A 40-year-old, gravida 3 para 2 (1-1-0-2), previous primary cesarean section for nonreassuring fetal status, presented at a tertiary hospital for confirmation of cesarean scar pregnancy (CSP). Transvaginal ultrasound confirmed a CSP at 8 2/7 weeks age of gestation with good embryonic cardiac activity, raising concern for early placenta accreta spectrum. A multidisciplinary team composed of an obstetrician, advanced pelvic surgeon, urologist, and anesthesiologist managed the patient. The patient underwent total abdominal hysterectomy with bilateral salpingectomy, as the patient has a completed family size. Before the procedure, she was given cefuroxime as prophylactic antibiotic. Intraoperatively, there were dense adhesions between the posterior bladder wall and the previous cesarean section scar. Inadvertent injury to the bladder wall was incurred during adhesiolysis. Cystorrhaphy was done by a urologist, while the rest of the surgery was unremarkable, with a 450 ml estimated blood loss. The postoperative course was unremarkable. Bladder rest was achieved by maintaining an indwelling Foley catheter, which remained in place upon discharge on postoperative day 3 and was continued for 7 days thereafter. At follow-up, a successful voiding trial was conducted, confirming the return of normal bladder function.

OBJECTIVE: Peritoneal dialysis(PD)-associated peritonitis is a common and major complication of PD and the most common cause of technical failure of PD. The presence of bacterial biofilm may be an important factor leading to refractory or recurrence of peritonitis. To investigate the formation and characteristics of bacterial biofilms on PD catheters after peritonitis-associated catheter removal. METHODS: The patients with maintenance PD who were regularly followed up in the Peking University People' s Hospital from June 2007 to January 2022 were retrospectively analyzed. The patients who withdrew from PD because of peritonitis and removed the PD catheter in our hospital and underwent the scanning electron microscope examination of the catheter were selected. The general information of the patients, the electron microscope results of the PD catheter and the bacterial culture results of the PD fluid were summarized. RESULTS: (1) A total of 18 patients were included, 11 were female (accounting for 61.1%). The average age of the patients was (59.1±11.5) years, and the average duration of dialysis was (80.1±47.4) months. Primary kidney diseases were predominantly chronic glomerulonephritis (55.6%), followed by diabetic nephropathy (27.8%), and others (16.6%). The reasons for catheters removal in 18 patients were refractory peritonitis in 11 cases, recurrent peritonitis in 5 cases, and fungal peritonitis in 2 cases. (2) 16 of the 18 patients (88.9%) had catheter bacterial biofilm, and the bacterial biofilm forms were all cocci. Some were arranged in grape-like shapes, and their diameters ranged from about 500 nm to 1 000 nm. The bacterial culture results of peritoneal dialysis fluid showed that the three most common pathogens were Escherichia coli, methicillin-sensitive Staphylococcus aureus (MSSA), and Staphylococcus epidermidis. (3) Among the 18 patients enrolled, 13 patients (72.2%) had peritonitis in the past. The causative bacteria of peritonitis in 9 patients were cocci, including coagulase-negative Staphylococci (Staphylococcus suis, Staphylococcus surface, Staphylococcus xylosus, Staphylococcus warneri), Staphylococcus aureus, Streptococcus (Streptococcus salivarius and Aerococus viridans). CONCLUSION Bacterial biofilm formation on the inner surface of PD catheter is common in peritonitis-associated catheter removal patients. Not all PD catheters removed due to peritonitis have bacterial biofilms. Bacterial biofilms and peritonitis pathogens may not be consistent.

OBJECTIVE: To investigate the differences in indwelling duration, clinical scenarios, and complications between the modified midline catheter (MMC) and the central venous catheter (CVC) in the treatment of patients in the medical intensive care unit (ICU) and the risk factors for complications based on real-world data. METHODS: A retrospective cohort study was conducted. The adult patients admitted to the medical ICU of the Third Xiangya Hospital of Central South University and had undergone placement of either a MMC or a CVC between January 1, 2023, and July 31, 2024, were consecutively enrolled by querying the hospital's electronic medical record system. Based on the type of catheter inserted, the patients were divided into the MMC group and the CVC group. The two groups were compared regarding the selection of catheters in the context of different underlying diseases, the actual clinical application after catheterization, catheter-related complications, the international normalized ratio (INR) and platelet count (PLT) during puncture and catheterization, the length of ICU stay, total length of hospital stay, catheter indwelling duration, and mortality during hospitalization. Multivariate Logistic regression analysis was employed to identify independent risk factors for catheter removal. RESULTS: Among the 274 patients, 52 received a MMC and 222 received a CVC. The utilization rate of MMC was significantly higher than that of CVC in patients with acute respiratory distress syndrome (ARDS), cardiovascular disease, and cancer [ARDS: 92.3% (48/52) vs. 70.3% (156/222), cardiovascular disease: 84.6% (44/52) vs. 54.5% (121/222), cancer: 30.8% (16/52) vs. 17.1% (38/222), all P < 0.05]. However, the use of MMC was significantly lower than CVC when vasoactive drug infusion was required [57.7% (30/52) vs. 79.7% (177/222), P < 0.05]. A significantly higher proportion of patients in the MMC group had a catheter indwelling time ≥ 12 days as compared with the CVC group [32.7% (17/52) vs. 13.5% (30/222), P < 0.05]. There were no statistically significant differences in other underlying diseases, venous access usage, INR and PLT during puncture and catheterization, length of ICU stay, total length of hospital stay, and in-hospital mortality of patients between the two groups. Regarding catheter-related complications, although the incidence of partial or complete catheter removal in the MMC group was significantly higher than that in the CVC group [36.5% (19/52) vs. 5.4% (12/222), P < 0.05], the incidence of puncture site fluid leakage, puncture site skin allergy, and deep vein thrombosis were significantly lower than those in the CVC group [puncture site fluid leakage: 1.9% (1/52) vs. 22.1% (49/222), puncture site skin allergy: 0% (0/52) vs. 20.7% (46/222), deep vein thrombosis: 3.8% (2/52) vs. 16.7% (37/222), all P < 0.05]. Furthermore, the proportion of patients experiencing three or more types of complications in the MMC group was significantly lower than that in the CVC group [5.8% (3/52) vs. 17.6% (39/222), P < 0.05]. Multivariate Logistic regression analysis of risk factors for catheter removal identified the use of a MMC [odds ratio (OR) = 8.518, 95% confidence interval (95%CI) was 3.710-19.560, P < 0.001] and a catheter indwelling time ≥ 12 days (OR = 3.133, 95%CI was 1.297-7.567, P = 0.011) as independent risk factors. CONCLUSIONS MMC was more frequently used in patients with ARDS, cardiovascular disease, and cancer, whereas CVC was primarily employed for vasoactive drug infusion. The use of MMC and a longer indwelling time were identified as independent risk factors for catheter removal. Despite a higher removal rate, the overall incidence of complications was significantly lower with MMC than with CVC. These findings suggest that MMC could serve as a routine alternative to CVC in most of clinical scenarios, provided that measures are implemented to prevent removal.

INTRODUCTION: Totally implantable venous access devices (TIVADs) or ports are increasingly used in oncology settings to provide long-term, easy venous access. This study reports our experience and results with 1180 cases in Singapore. METHOD: Data from January 2019 to January 2022, obtained from a hospital-approved secure database application called the Research Electronic Data Capture registry, were reviewed and analysed retrospectively. RESULTS: A total of 1180 patients underwent TIVAD implantation with a 100% technical success rate. The mean age of the cohort was 61.9 years. The mean dwell duration was 342 days (standard deviation [SD] 223; range 3-1911). By 1 February 2022, 83% of patients were still using the TIVAD, 13.6 % underwent removal after completion of treatment, 2.1% were removed due to infection, 0.6% due to malfunction, 0.6% due to port extrusion and 0.1% at patient's request. The right internal jugular vein (IJV) was the most commonly accessed site (83.6%), followed by the left IJV (15.6%). The early post-procedure complications were pain (24.7%), bruising (9.2%), swelling (3.6%), bleeding (0.5%), fever (0.4%), itchiness (0.2%) and allergic dermatitis (0.1%). The delayed post-procedure complications were TIVAD site cellulitis (3.80%); discharge (1.10%); skin erosion with device extrusion (0.60%); malpositioned catheter (0.33%), which was successfully repositioned, catheter-related bloodstream infections (0.25%); migration of TIVAD leading to catheter dislodgement (0.25%); venous thrombosis (0.25%); fibrin sheath formation requiring stripping (0.10%) and TIVAD chamber inversion (0.10%). CONCLUSION TIVAD implantation via the jugular vein under radiological guidance provides a safe, reliable and convenient means of long-term venous access in oncology patients. By sharing our experience and acceptable outcomes from a large oncology cohort, we aim to increase the awareness and adoption of TIVAD usage in oncology patients, especially in Asia.

OBJECTIVE: To provide evidence for further reducing the incidence of central line-associated bloodstream infection (CLABSI) according to investigation of the prevention and control of CLABSI in intensive care unit (ICU) in Shandong Province. METHODS: The questionnaire was developed by experts from Shandong Critical Care Medical Quality Control Center, combining domestic and foreign guidelines, consensus and research. A convenient sampling method was used to recruit survey subjects online from October 11 to 31, 2023 in the province to investigate the management status of central venous catheter (CVC) in ICU units of secondary and above hospitals. RESULTS: A total of 201 valid data were collected, involving 186 hospitals in the province, with a total of 201 ICU units, mainly comprehensive ICU (91%). The beds in ICU units were mainly single rooms (89%) and triple rooms (79%), and the ratio of doctors to total beds was 0.54 : 1. The training on the knowledge and operation of intravascular catheter-associated bloodstream infection in each ICU unit was mainly irregular (49%), and 96% of the catheter operators were authorized by the hospital. In terms of CVC selection, 89% of ICU units used dual-chamber CVC, and 86% of ICU units used catheters without antibiotic coating. When selecting the placement site, for conventional CVC catheterization, 65% preferred subclavian vein. Femoral vein was preferred in 87% of ICU units undergoing continuous renal replacement therapy. 95% of ICU units had established standardized operation procedure (SOP) for CVC placement. 86% of ICU units were capable of ultrasound positioning or guided puncture at the time of catheterization. During catheterization, 88% of ICU units met the sterile dress code. Before and after catheterzation, 81% and 77% of ICU units standardized hand hygiene. Only 31% of ICU units were covered from head to toe by aseptic wipes. For the choice of skin disinfectant, the majority of ICU units (72%) only used iodophor. After tube placement, 54% of ICU units chose sterile transparent dressing and 25% chose sterile gauze dressing. 98% of ICU units were sutured to secure the catheter. Regarding catheter replacement and removal, 45% of ICU units could not be removed or replaced within 2 days in emergency situations where the principle of sterility was not guaranteed. When CLABSI was suspected, 55% of ICU units were able to obtain the catheter tip, transcatheter blood culture, and contralateral peripheral vein blood culture at the same time. For CVC replacement frequency, most ICU units (75%) would not be replaced regularly, and some ICU units would be replaced regularly, but the frequency of replacement was different. For CLABSI prevention and control, 82% of ICU units developed a verification form or supervision form. When analyzing the sources of CLABSI data, most of them were filled in by themselves (60%). As for the frequency of data analysis, 57% were once a month. CONCLUSIONS All ICU units in Shandong Province are standardized in terms of the authorization of operators, the formulation of SOP, the formulation and implementation of verification form and supervision form, ultrasound-guided puncture, and hand hygiene before and after catheterization. However, there are still deficiencies in the training on knowledge and operation of intravascular catheter-associated bloodstream infections, maximum aseptic coverage, catheter replacement and removal, and the reporting sources of CLABSI data, which need to be strengthened in the follow-up work. At present, the selection of CVC, the selection of catheterization site, the selection of skin disinfectant and the selection of dressings after catheterization still need further research.

Objective To compare the clinical effects of three treatment methods including systemic thrombolysis(ST),catheter-directed thrombolysis(CDT),and AngioJet percutaneous mechanical thrombectomy(PMT)in acute lower extremity deep venous thrombosis(LEDVT). Methods The data of 82 patients diagnosed with LEDVT in the Department of Vascular and Gland Surgery of the First Affiliated Hospital of Hebei North University from January 2017 to December 2020 were collected.The patients were assigned into a ST group(n=50),a CDT group(n=16),and a PMT group(n=16)according to different treatment methods.The efficacy and safety were compared among the three groups. Results Compared with that before treatment,the circumferential diameter difference of both lower limbs on days 1,2,and 3 of treatment in the ST,CDT,and PMT groups reduced(all P<0.001).The PMT group showed smaller circumferential diameter difference of lower limbs on days 1,2,and 3 of treatment than the ST group(all P<0.001)and smaller circumferential diameter difference of the lower patellar margin on day 1 of treatment than the CDT group(P<0.001).The PMT group showed higher diminution rate for swelling of the affected limb at the upper and lower edges of the patella than the ST group(P<0.001)and higher diminution rate for swelling at the upper edge of the patella than the CDT group(P=0.026).The incidence of complications after treatment showed no significant differences among the three groups(all P>0.05).The median of hospital stay in the PMT group was shorter than that in the ST and CDT groups(P=0.002,P=0.001).The PMT group had higher thrombus clearance rate than the ST group(P=0.002)and no significant difference in the thrombus clearance rate from the CDT group(P=0.361).The vascular recanalization rates in the PMT(all P<0.001)and CDT(P<0.001,P=0.002,P=0.009)groups 3,6,and 12 months after treatment were higher than those in ST group,and there were no significant differences between PMT and CDT groups(P=0.341,P=0.210,P=0.341). Conclusions ST,CDT,and PMT demonstrated significant efficacy in the treatment of LEDVT,and PMT was superior to ST and CDT in terms of circumferential diameter difference of the lower limbs,diminution rate for swelling of the affected limb,thrombus clearance rate,length of hospital stay,and long-term vascular recanalization.There was no obvious difference in safety among the three therapies.

The female infant in this case study was admitted to the hospital 4 hours after birth due to preterm birth and respiratory distress. On the third day after birth, peripherally inserted central venous catheter (PICC) catheterization was performed. On day 42, thrombus was found at the entrance of the right atrium from the inferior vena cava during a cardiac ultrasound, and it was considered to be related to PICC placement. Low-molecular-weight heparin and urokinase were given. After two weeks of treatment, ultrasonic monitoring showed thrombus shrinkage. No bleeding or pulmonary embolism occurred during the treatment. The patient discharged after improvement. This article mainly introduces a multidisciplinary team approach to diagnosis and treatment of PICC-related thrombosis in neonates.

OBJECTIVE: To evaluate the effectiveness and safety of Rotarex catheter system in treating femoropopliteal artery stenosis accompanied with thrombosis. METHODS: From Jun. 2017 to Dec. 2019, the clinical data of 32 femoropopliteal artery stenosis accompanied with thrombosis cases treated with Rotarex catheter system were retrospectively analyzed. There were 23 males and 9 females aged from 50 to 89 years and the mean age was (70.7±10.3) years. Six cases had acute course of disease (≤2 weeks), 17 cases had subacute course of disease (>2 weeks, ≤3 months), and 9 cases had chronic course of disease (>3 months). Mean lesion length was (23.4±13.7) cm, mean occlusion length was (19.9±13.3) cm, and in-stent occlusion 7 cases. The superficial femoral artery (SFA) was involved in 13 cases, the popliteal artery (PA) was involved in 8 cases, and both SFA and PA were involved in the other 11 cases. All the cases were treated with Rotarex catheter system. When necessary, suction with large lumen catheter was enabled. Residual stenosis was treated with percutaneous transluminal angioplasty (PTA). Drug-coated balloon (DCB) was only used in patients with financial status, and stent was used only when it was necessary. Heparin was used for 24 h after procedures, and after that, antiplatelet agents were used. Doppler ultrasonography was taken during the followed-up. RESULTS: Technical success was 100%, and mean procedure time was (107.4±21.5) min. 8F (1F≈0.33 mm) and 6F Rotarex catheter were used in 27 and 5 cases respectively. In 27 cases, forward flow was obtained immediately after debulking with Rotarex catheter, and in the other 5 cases, suction with large lumen catheters were used. PTA was used in all 32 cases. DCB were used in 8 cases, of which 4 were used in in-stent stenosis. Twelve cases were implanted stents. There were no perioperative deaths. The only one procedure related complication was distal embolism. We took out the thrombus with guiding catheter. In all cases, mean hospital stay were (4.6±1.5) d. The ankle brachial index increased from 0.32±0.15 to 0.86±0.10 after treatment (t=-16.847, P < 0.001). The Rutherford stages decreased significantly (Z=-4.518, P < 0.001). All the patients were followed up for 6.0-36.0 months, and the median time was 16.0 months. 2 cases stopped antiplatelet agents, which resulted in acute thrombosis. Another percutaneous mechanical thrombectomy and PTA were taken in one of them. Two cases died of cardiovascular disease during the follow-up, and no amputation was observed. Target lesion restenosis occurred in 7 cases during the follow-up, and target lesion revascularization (TLR) was taken in two of them. CONCLUSION In treating femoropopliteal artery stenosis accompanied with thrombosis, Rotarex catheter can remove thrombus effectively, and that can expose underlying lesions and reduce stent use and complications rates. It is a safe and effective method.

Objective: To investigate the timing of pericardial drainage catheter removal and restart of the anticoagulation in patients with atrial fibrillation (AF) suffered from perioperative pericardial tamponade during atrial fibrillation catheter ablation and uninterrupted dabigatran. Methods: A total of 20 patients with pericardial tamponade, who underwent AF catheter ablation with uninterrupted dabigatran in Beijing Anzhen Hospital from January 2019 to August 2021, were included in this retrospective analysis. The clinical characteristics of enrolled patients, information of catheter ablation procedures, pericardial tamponade management, perioperative complications, the timing of pericardial drainage catheter removal and restart of anticoagulation were analyzed. Results: All patients underwent pericardiocentesis and pericardial effusion drainage was successful in all patients. The average drainage volume was (427.8±527.4) ml. Seven cases were treated with idarucizumab, of which 1 patient received surgical repair. The average timing of pericardial drainage catheter removal and restart of anticoagulation in 19 patients without surgical repair was (1.4±0.7) and (0.8±0.4) days, respectively. No new bleeding, embolism and death were reported during hospitalization and within 30 days following hospital discharge. Time of removal of pericardial drainage catheter, restart of anticoagulation and hospital stay were similar between patients treated with idarucizumab or not. Conclusion: It is safe and reasonable to remove pericardial drainage catheter and restart anticoagulation as soon as possible during catheter ablation of atrial fibrillation with uninterrupted dabigatran independent of the idarucizumab use or not in case of confirmed hemostasis.
