OBJECTIVE: To explore predictive value of Caprini score, Wells score and Autar score for lower extremity deep vein thrombosis (DVT) after hip fracture in elderly patients. METHODS: A total of 310 elderly patients with hip fracture were selected from January 2018 to September 2022. According to the lower extremity color ultrasound examination results, 155 patients with DVT were divided into thrombosis group, included 42 males and 113 females, aged from 60 to 101 years old with an average of (80.58±8.84) years old; and 155 patients without DVT were divided into control group, included 58 males and 97 females, aged from 60 to 94 years old with an average of (79.01±8.99) years old. Caprini score, Wells score and Autar score immediately after admission were collected and compared between two groups. Receiver operating characteristic (ROC) curve was used to evaluate predictive value of three thrombus risk assessment tables for DVT after hip fracture in elderly patients. RESULTS: Caprini score, Wells score and Autar score in thrombus group were significantly higher than those in control group (P<0.001). ROC curve analysis results showed that the best cut-off value of Caprini score was 8.5 points, the sensitivity was 46.5%, the specificity was 99.4%, and area under the curve(AUC) was 0.763. The best cut-off value of Wells score was 1.5, the sensitivity was 100%, the specificity was 99.4%, and AUC was 0.998. The best cut-off value of Autar score was 10.5 points, the sensitivity was 58.1%, the specificity was 84.5%, and AUC was 0.717. CONCLUSION Caprini scale, Wells scale and Autar scale all have good predictive efficacy for the risk of DVT in elderly patients with hip fracture, and could provide an important reference for clinical guidance for prevention, management and treatment of DVT after hip fracture in elderly patients, among which Wells scale has a higher predictive value.

PURPOSE: Static progressive stretch (SPS) can be applied to treat chronic joint stiffness. However, the impacts of subacute application of SPS to the distal lower limbs, where deep vein thrombosis (DVT) is common, on venous thromboembolism remain unclear. This study aims to explore the risk of venous thromboembolism events following subacute application of SPS. METHODS: A retrospective cohort study was conducted on patients diagnosed with DVT following a lower extremity orthopedic surgery before being transferred to the rehabilitation ward from May 2017 to May 2022. Patients with unilateral lower limb comminuted para-articular fractures, transferred to rehabilitation ward for further treatment within 3 weeks after operation, followed up more than 12 weeks since initial manual physiotherapy, and diagnosed DVT by ultrasound before rehabilitation course were included in the study. Patients with polytrauma, without evidence of previous peripheral vascular disease or incompetence, had medication for thrombosis treatment or prophylaxis before the operation, detected with paralysis due to nervous system impairment, infected after operation during the regime, or with acute progression of DVT were excluded. The included patients were randomized to the standard physiotherapy and the SPS integrated groups for observation. Associated DVT and pulmonary embolism data were collected during the physiotherapy course to compare the groups. SSPS 28.0 and GraphPad Prism 9 were used for data processing. A p < 0.05 was set significant difference. RESULTS: In total of 154 patients with DVT participating in this study, 75 of them were treated with additional SPS for postoperative rehabilitation. The participants in the SPS group showed improved range of motion (12.3° ± 6.7°). However, in the SPS group, there was no difference in thrombosis volume between the start and termination (p = 0.106, p = 0.787, respectively), although difference was seen intra-therapy (p < 0.001). Contingency analysis revealed the pulmonary embolism incidence (OR = 0.703) in the SPS group compared to the mean physiotherapy. CONCLUSION The SPS technique is a safe and reliable option to prevent potential joint stiffness without aggravating the risk of distal DVT for postoperative patients suffering from relevant trauma.

Objective: To investigate the predictive value of D-dimer for deep venous thrombosis (DVT) of lower extremity in adult burn patients. Methods: A retrospective case series study was conducted. The clinical data of 3 861 adult burn patients who met the inclusion criteria and were admitted to the Department of Burns of Zhengzhou First People's Hospital from January 1, 2015 to December 31, 2019 were collected. The patients were divided into DVT group (n=77) and non-DVT group (n=3 784) according to whether DVT of lower extremity occurred during hospitalization or not. Data of patients in the two groups were collected and compared, including the gender, age, total burn area, D-dimer level, with lower limb burn and inhalation injury or not on admission, with sepsis/septic shock, femoral vein indwelling central venous catheter (CVC), history of surgery, and infusion of concentrated red blood cells or not during hospitalization. Data were statistically analyzed with independent sample t test, Mann-Whitney U test, and chi-square test. The indicators with statistically significant differences between the two groups were analyzed with multivariate logistic regression analysis to screen the independent risk factors for DVT of lower extremity in 3 861 adult burn patients. The receiver operating characteristic (ROC) curve of the independent risk factors predicting DVT of lower extremity in 3 861 adult burn patients were drawn, and the area under the curve (AUC), the optimal threshold value, and the sensitivity and specificity under the optimal threshold value were calculated. The quality of the AUC was compared by Delong test, and the sensitivity and specificity under the optimal threshold value were compared using chi-square test. Results: There were no statistically significant differences in gender, occurrence of sepsis/septic shock or history of surgery during hospitalization between patients in the two groups (P>0.05), while there were statistically significant differences in age, total burn area, D-dimer level, lower limb burn and inhalation injury on admission, and femoral vein indwelling CVC and infusion of concentrated red blood cells during hospitalization between patients in the two groups (t=-8.17, with Z values of -5.04 and -10.83, respectively, χ² values of 21.83, 5.37, 7.75, and 4.52, respectively, P<0.05 or P<0.01). Multivariate logistic regression analysis showed that age, total burn area, and D-dimer level were the independent risk factors for DVT of lower extremity in 3 861 adult burn patients (with odds ratios of 1.05, 1.02, and 1.14, respectively, 95% confidence intervals of 1.04-1.06, 1.00-1.03, and 1.10-1.20, respectively, P<0.05 or P<0.01). The AUCs of ROC of age, total burn area, and D-dimer level for predicting DVT of lower extremity in 3 861 adult burn patients were 0.74, 0.67, and 0.86, respectively (with 95% confidence intervals of 0.68-0.80, 0.60-0.74, and 0.83-0.89, respectively, P values<0.01), the optimal threshold values were 50.5 years old, 10.5% total body surface area, and 1.845 mg/L, respectively, the sensitivity under the optimal threshold values were 71.4%, 70.1%, and 87.0%, respectively, and the specificity under the optimal threshold values were 66.8%, 67.2%, and 72.9%, respectively. The AUC quality and sensitivity and specificity under the optimal threshold value of D-dimer level were significantly better than those of age (z=3.29, with χ² values of 284.91 and 34.25, respectively, P<0.01) and total burn area (z=4.98, with χ² values of 326.79 and 29.88, respectively, P<0.01), while the AUC quality and sensitivity and specificity under the optimal threshold values were similar between age and total burn area (P>0.05). Conclusions: D-dimer level is an independent risk factor for DVT of lower extremity in adult burn patients, its AUC quality and sensitivity and specificity under the optimal threshold value are better than those of age and total burn area, and it has good predictive value for DVT of lower extremity in adult burn patients.

OBJECTIVE: To observe the clinical effect of moxibustion combined with plucking technique at Jiquan (HT 1) for preventing peripherally inserted central catheter (PICC)-related venous thrombosis in the upper limbs of malignant tumor patients. METHODS: A total of 80 malignant tumor patients undergoing PICC were randomized into an observation group and a control group, 40 cases in each one. In the control group, the routine care for PICC was exerted. In the observation group, besides the routine care, moxibustion combined with plucking technique at Jiquan (HT 1) was added. Mild moxibustion was exerted along the venous distribution of PICC (avoiding the entry site) for 10 to 15 min, and then, the circling moxibustion was applied to Quchi (LI 11), Xuehai (SP 10) and Tianfu (LU 3), 3 to 5 min at each acupoint. Finally, plucking technique was given at Jiquan (HT 1) for 5 to 10 min. This combined therapy was intervened since the 2nd day of PICC placement, once daily, 5 times a week, for 3 weeks totally. The incidence of the PICC-related venous thrombosis in the upper limbs was compared between the two groups on day 42 of placement. On day 2, 7, 14, 21, 28, 35 and 42 of PICC placement, the peak systolic velocity (PSV) and the end-diastolic velocity (EDV) of the subclavicular vein on the placement side were observed separately in the two groups. RESULTS: The incidence of the PICC-related venous thrombosis in the upper limbs in the observation group was lower than that in the control group (2.5% [1/40] vs 17.5% [7/40], P<0.05). From day 7 to 35 of PICC placement, PSV of the subclavicular vein on the placement side was higher than that on the day 2 of PICC placement in the observation group (P<0.05). On day 28 and 42 of PICC placement, PSV of the subclavicular vein on the placement side was lower than that on the day 2 of PICC placement in the control group (P<0.05). In the observation group, EDV of the subclavicular vein on the placement side was higher than that on the day 2 of PICC placement from day 7 to 28 of PICC placement (P<0.05). In the control group, EDV of the subclavicular vein on the placement side from day 28 to 42 of PICC placement was lower than that on the day 2 of PICC placement (P<0.05). From day 7 to 42 of PICC placement, PSV and EDV of the subclavicular vein on the placement side in the observation group were all higher than those in the control group (P<0.01, P<0.05). CONCLUSION The combined treatment of moxibustion with plucking technique at Jiquan (HT 1) can effectively prevent PICC-related venous thrombosis in the upper limbs and improve venous blood flow velocity in malignant tumor patients.

OBJECTIVES: To analyze the risk factors for postoperative deep vein thrombosis (DVT) in neurosurgical patients to provide the basis for the prevention of postoperative DVT. METHODS: A total of 141 patients underwent neurosurgery were enrolled. Thrombelastography (TEG) test was performed before and at the end of surgery. According to whether there was DVT formation after operation, the patients were divided into a thrombosis group and a non-thrombosis group. -test and rank sum test were used to compare the general clinical characteristics of the 2 groups, such as age, gender, intraoperative blood loss, -dimer, intraoperative crystal input, colloid input, blood product transfusion, operation duration, length of postoperative hospitalization. The application of chi-square test and rank-sum test were used to compared TEG main test indicators such as R and K values between the 2 groups. Logistic regression was used to analyze the possible risk factors for postoperative DVT in neurosurgical patients. RESULTS: There were significant differences in postoperative TEG index R, clotting factor function, intraoperative blood loss, hypertension or not, length of postoperative hospital stay, and postoperative absolute bed time (all <0.05). Logistic regression analysis showed hypercoagulability, more intraoperative blood loss and longer postoperative absolute bed time were risk factors for DVT formation after craniotomy. CONCLUSIONS Hypercoagulability in postoperative TEG test of patients is an important risk factor for the formation of postoperative DVT after neurosurgery, which can predict the occurrence of postoperative DVT to some extent.

PURPOSE: Periprosthetic fracture (PPF) is a serious complication that occurs in 0.3%-2.5% of all total knee arthroplasties used to treat end-stage arthritis. To our knowledge, there are no studies in the literature that evaluate the association between time to surgery after PPF and early postoperative infections or deep vein thrombosis (DVT). This study tests our hypothesis that delayed time to surgery increases rates of postoperative infection and DVT after PPF surgery. METHODS: Our study cohort included patients undergoing PPF surgery in the American College of Surgeons National Surgical Quality Improvement Program database (2006-2015). The patients were dichotomized based on time to surgery: group 1 with time ≤2 days and group 2 with time >2 days. A 2-by-2 contingency table and Fisher's exact test were used to evaluate the association between complications and time to surgery groups, and multivariate logistic regression was used to adjust for demographics and known risk factors. RESULTS: A total of 263 patients (80% females) with a mean age of 73.9 ± 12.0 years were identified receiving PPF surgery, among which 216 patients were in group 1 and 47 patients in group 2. Complications in group 1 included 3 (1.4%) superficial infections (SI), 1 (0.5%) organ space infection (OSI), 1 (0.5%) wound dehiscence (WD), and 4 (1.9%) deep vein thrombosis (DVT); while complications in group 2 included 1 (2.1%) SI, 1 (2.1%) OSI, 1 (2.1%) DVT, and no WD. No significant difference was detected in postoperative complications between the two groups. However, patients in group 2 were more likely (p = 0.0013) to receive blood transfusions (57.5%) than those in group 1 (32.4%). CONCLUSION Our study indicates patients with delayed time to surgery have higher chance to receive blood transfusions, but no significant difference in postoperative complications (SI, OSI, WD, or DVT) between the two groups.

Surgical operation in treating obesity and type 2 diabetes is popularizing rapidly in China. Correct prevention and recognition of perioperation-related operative complications is the premise of ensuring surgical safety. Familiar complications of the operation include deep venous thrombosis, pulmonary artery embolism, anastomotic bleeding, anastomotic fistula and marginal ulcer. The prevention of deep venous thrombosis is better than treatment. The concrete measures contain physical prophylaxis (graduated compression stocking and intermittent pneumatic compression leg sleeves) and drug prophylaxis (unfractionated heparin and low molecular heparin), and the treatment is mainly thrombolysis or operative thrombectomy. The treatment of pulmonary artery embolism includes remittance of pulmonary arterial hypertension, anticoagulation, thrombolysis, operative thrombectomy, interventional therapy and extracorporeal membrane oxygenation (ECMO). Hemorrhage is a rarely occurred but relatively serious complication after bariatric surgery. The primary cause of anastomotic bleeding after laparoscopic gastric bypass is incomplete hemostasis or weak laparoscopic repair. The common bleeding site in laparoscopic sleeve gastrectomy is gastric stump and close to partes pylorica, and the bleeding may be induced by malformation and weak repair technique. Patients with hemodynamic instability caused by active bleeding or excessive bleeding should timely received surgical treatment. Anastomotic fistula in gastric bypass can be divided into gastrointestinal anastomotic fistula and jejunum-jejunum anastomotic fistula. The treatment of postoperative anastomotic fistula should vary with each individual, and conservative treatment or operative treatment should be adopted. Anastomotic stenosis is mainly related to the operative techniques. Stenosis after sleeve gastrectomy often occurs in gastric angle, and the treatment methods include balloon dilatation and stent implantation, and surgical treatment should be performed when necessary. Marginal ulcer after gastric bypass is a kind of peptic ulcer occurring close to small intestine mucosa in the junction point of stomach and jejunum. Ulcer will also occur in the vestige stomach after laparoscopic sleeve gastrectomy, and the occurrence site locates mostly in the gastric antrum incisal margin. Preoperative anti-HP (helicobacter pylorus) therapy and postoperative continuous administration of proton pump inhibitor (PPI) for six months is the main means to prevent and treat marginal ulcer. For patients on whom conservative treatment is invalid, endoscopic repair or surgical repair should be considered. Different surgical procedures will generate different related operative complications. Fully understanding and effectively dealing with the complications of various surgical procedures through multidisciplinary cooperation is a guarantee for successful operation.

BACKGROUNDDeep vein thrombosis (DVT) may be associated with iliac vein compression. Up to now, the majority of data has come from a retrospective study about the correlation between DVT and iliac vein compression. This prospective study was to determine the incidence of DVT in individuals with iliac vein compression and identify risk factors predictive of DVT.

METHODSA total of 500 volunteers without symptoms of venous diseases of lower extremities and overt risk factors of deep venous thrombosis between October 2011 and September 2012 in Shijitan Hospital were enrolled in this cohort study. All the participants underwent contrast-enhanced abdominal computed tomography (CT) to evaluate iliac vein compression. Baseline demographic information and degree of iliac vein compression were collected. They were categorized into ≥50% or <50% iliac vein compression group. Ultrasound examination was performed to screen DVT at the time of CT examination and 3, 6, 9, and 12 months after the examination. Primary event was DVT of ipsilateral lower extremity. Correlation between DVT and iliac vein compression was estimated by multivariate Logistic regression after adjusting for age, gender, malignancy, surgery/immobilization, chemotherapy/hormonal therapy, and pregnancy.

RESULTSIn 500 volunteers, 8.8% (44) had ≥50% iliac vein compression and 91.2% (456) had <50% iliac vein compression. Ipsilateral DVT occurred in six volunteers including two in iliofemoral vein, two in popliteal vein, and two in calf vein within 1 year. Univariate analysis showed that the incidence of DVT was 6.8% in ≥50% compression group, significantly higher than that in <50% compression group (0.7%) (χ2 = 12.84, P = 0.01). Patients with malignancy had significantly higher incidence of DVT than those without malignancy (χ2 = 69.60,P< 0.01). Multivariate Logistic regression indicated that iliac vein compression and malignancy were independent risk factors of DVT. After adjustment for malignancy, patients with ≥50% iliac vein compression had 10-fold increased risk of developing DVT (adjusted relative risk [RR] = 10.162, 95% confidence interval [CI]: 1.149-89.865, P = 0.037). In subgroup analysis, patients with malignancy and ≥50% iliac vein compression had 12-fold increased the risk of DVT than those without malignance and ≥50% compression (RR = 12.389, 95% CI: 2.327-65.957, P = 0.003).

CONCLUSIONSIliac vein compression is common, but the incidence of DVT is low. Only individuals with ≥50% iliac vein compression or compression combined with other risk factors might have significantly increased the risk of DVT. Further study is recommended to improve prevention strategies for DVT in significant iliac vein compression.
