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.

PURPOSE: The aim of this study was to investigate the efficacy of low-molecular-weight heparin (LMWH) for the prevention of venous thromboembolism in Korean patients who underwent hip fracture surgery (HFS). MATERIALS AND METHODS: Prospectively, a total 181 cases were classified into the LMWH user group (116 cases) and LMWH non-user group (65 cases). Each group was sub-classified according to fracture types as follows: 81 cases of intertrochanteric fracture (group A: 49, group B: 32) and 100 cases of neck fracture (group C: 67, group D: 33). We compared the incidence of deep vein thrombosis (DVT) and pulmonary embolism (PE) according to LMWH use. RESULTS: Of the 181 cases, four DVTs were found in the LMWH user groups (1 in group A, and 3 in group C). One case of PE was found in LMWH non-user group D. The incidences of DVT and PE showed no statistically significant differences between the LMWH user and non-user groups (p=0.298 and 0.359, respectively). In subgroup analysis, no statistically significant differences were found between groups A and B and between groups C and D. CONCLUSION: The administration of LMWH was not effective in the prevention of venous thromboembolism and PE in the Korean patients who underwent HFS.

BACKGROUNDVenous thromboembolism is known to be an important social and health care problem because of its high incidence among patients who undergo surgery. Studies on the mechanical prophylaxis of thromboembolism after gynaecological pelvic surgery are few. The aim of our study was to evaluate the effect of mechanical thromboembolism prophylaxis after gynaecological pelvic surgery using a combination of graduated compression stockings (GCS) and intermittent pneumatic compression (IPC) or GCS alone.

METHODSThe study was performed on 108 patients who were randomly assigned to two groups. The first group received GCS before the operation and IPC during the operation (IPC + GCS group). The second group received GCS before the operation (GCS group). To analyze the effect of the preventive measures and the laboratory examination on the incidence of thrombosis and to compare the safety of these measures, the incidence of adverse reactions was assessed.

RESULTSThe morbidity associated with DVT was 4.8% (5/104) in the IPC + GCS group and 12.5% (14/112) in the GCS group. There were significant statistical differences between the two groups. There were no adverse effects in either group.

CONCLUSIONSThe therapeutic combination of GCS and IPC was more effective than GCS alone for thrombosis prevention in high-risk patients undergoing gynaecological pelvic surgery, and there were no adverse effects in either group.

OBJECTIVETo summarize the prevention and treatment experience of deep vein thrombosis in patients with abdominal tumors after standardized resection and lymph node dissection, and to investigate a standard therapeutic measure of thrombosis prevention in these patients.

METHODSThe clinical data of 548 patients who received radical operation and standardized lymph node dissection for abdominal tumors from January 2007 to April 2010 were analyzed retrospectively. According to different therapeutic scheme and time, the patients were divided into three groups: Group 1 included 163 cases from January 2007 to March 2008 were treated with compound Danshen injection 0.2 g and low molecular weight dextran 500 ml on the same day of surgery for 7 days; Group 2 included 149 cases from April 2008 to March 2009 were treated with the same regimen as that in Group 1 plus low molecular heparin 40 mg on the same day of surgery for 7 days; Group 3 included 236 cases from April 2009 to April 2010 were treated with the same regimen as that in Group 1 plus low molecular heparin on the third day of surgery for 7 days. The treatment effects and the complications in the three groups were analyzed and compared.

RESULTSSixty-four (39.3%) cases were D-Dimer positive and 15 (9.2%) cases were DVT positive under color Doppler ultrasound examination in Group 1; and those were 38 (25.5%) and 3 (2.0%) in Group 2; and 62 (26.3%) and 6(2.5%) in Group 3. Overall observation, the incidences of thrombosis in Group 2 and 3 were obviously lower than that of Group 1, but there was no significant difference between Group 2 and 3. Earlier use of low molecular heparin would lead to some complications.

CONCLUSIONSIt brings better effects in thrombosis prevention by using compound Danshen injection and low molecular weight dextran on the day of surgery, with low molecular heparin on the third day of surgery.

OBJECTIVE: To explore the effects of different administration methods of tranexamic acid(TXA) on the perioperative blood loss, hidden blood loss, transfusion rate and adverse reactions in lumbar spinal decompression and fusion. METHODS: Sixty patients who received lumbar spinal canal decompression and fusion from July 2019 to July 2020 were enrolled and divided into observation group and control group, with 30 cases in each group. The observation group was given 2 g TXA orally at 2 hours before operation, control group was given 1 g TXA for 5-10 min before skin incision and 6 hours after operation intravenously. The intraoperative blood loss, postoperative drainage, total blood loss, hidden blood loss, drainage tube removal time, blood transfusion rate, venous thrombosis rate, adverse event rate were recorded respectively. The changes of hemoglobin(Hb) and hematocrit (HCT) were observed before operation and 1, 3 days after operation. RESULTS: Hb and HCT at 1 and 3 days after operation were significantly improved compared with those before operation(P<0.01). However, there was no significant difference between the groups(P>0.05). There were no significant difference in amount of blood loss, postoperative drainage, total blood loss, intraoperative blood loss, hidden blood loss, postoperative drainage time, and blood transfusion rate between two groups (P>0.05). There were no venous thrombosis and adverse events occurred in both groups. CONCLUSION During the perioperative period of lumbar spinal decompression and fusion, oral TXA and intravenous TXA have the same effect in reducing perioperative blood loss and are safe and reliable. It is recommended that oral TXA be used to save medical costs and convenience.

OBJECTIVETo evaluate the application of inferior vena cava filter (IVCF) in prevention of peri-operative pulmonary embolism (PE) in lower limb bone fracture patients with deep venous thrombosis (DVT).

METHODSFrom January 2003 to December 2012, 2 248 cases of lower limb and pelvic fractures with DVT were retrospectively analyzed. Before the procedure of IVCF implantation began, January 2003 to December 2007, there were 1 052 cases of acute trauma patients with DVT were classified as the group of early none-IVCF. The IVCF implantation was began since January 2008. From that time to December 2012, 712 cases of bone fractures with DVT received filter implantation, which were classified as IVCF group. The other 484 patients who had not undergone filter deployment were divided as group of late none-IVCF. The baseline conditions of the three groups were significantly different in addition to the ages between group of early none-IVCF and IVCF group. The incidences of PE and mortality of PE in each group were recorded and analyzed by χ(2) test.

RESULTSThere were totally 31 cases of symptomatic PE, among which 12 cases died. Totally 712 filters were deployed successfully without any major complications. The incidences of symptomatic PE were 0.14% (1/712), 2.19% (23/1 052) and 1.45% (7/484) in IVCF group, group of early none-IVCF and group of late none-IVCF, respectively. The mortality of PE were 0 (0/712), 0.86% (9/1 052) and 0.62% (3/484) in these groups. The incidence of symptomatic PE in IVCF group was significantly different from that in the group of early and late none-IVCF (χ(2) = 11.762, P = 0.001; χ(2) = 7.395, P = 0.007, respectively). The mortality of IVCF group was also significantly lower compared with the other two groups (χ(2) = 6.122, P = 0.013; χ(2) = 4.424, P = 0.035, respectively).

CONCLUSIONIVCF implantation effectively prevents symptomatic and fatal PE of patients of lower limb and pelvic fractures with DVT in the peri-operative period.

OBJECTIVETo investigate the impact of hemocoagulase on coagulatory function and deep venous thrombosis after abdominal surgery.

METHODSFrom June 2008 to January 2009, 60 cases (gastric cancer 20 cases, colonic cancer 40 cases) undergoing gastrointestinal surgery at the Union Hospital of Fujian Medical University were randomized to the hemocoagulase group and the control group(n=30 in each group). Intravenous hemocoagulase at a daily dose of 2U was used on the same day and the next day postoperatively in the hemocoagulase group. D-dimer(D-D), tissue plasminogen activator(t-PA), plasminogen activator inhibitor-1(PAI-1), PT, APTT, TT, platelet count were measured before and after operation. Doppler ultrasound examination was carried out to exclude deep venous thrombosis on the 5th to 7th days after operation.

RESULTSSignificant increased D-D, t-PA, PAI-1, prolonged PT, APTT, shortened TT and lower platelet count after surgery were noticed as compared to the baseline in both groups(P<0.05, P<0.01). PT, APTT, D-D, t-PA, and PAI-1 significantly increased, and TT significantly shortened in the hemocoagulase group as compared to the control group after surgery(P<0.05, P<0.01). Deep venous thrombosis in the left lower limbs was noticed in 7 patients(23.3%) in the hemocoagulase group and 3 cases(10.0%) in the control group, however the difference was not statistically significant(P>0.05).

CONCLUSIONSHypercoagulable state usually appears after abdominal surgery and use of hemocoagulase may aggravate hypercoagulability and increase the incidence of deep venous thrombosis in lower limbs after abdominal surgery. Preventative use of hemocoagulase must be administered with caution.

We sought to document the clinical performance of the 1st American Academy of Orthopaedic Surgeons (AAOS) guideline on the prevention of symptomatic pulmonary embolism (PE) after total knee arthroplasty (TKA) in Korean patients, in terms of the proportions of the each risk-stratified group, efficacy and safety. Consecutive 328 patients underwent TKA were preoperatively assessed for the risks of PE and bleeding and categorized into 4 groups: 1) standard risk, 2) high risk for PE, 3) high risk for bleeding, and 4) high risks both for PE and bleeding. One of three options was administered according to the groups (aspirin in group 1 or 4; enoxaparin and following aspirin in group 2; antithrombotic stocking in group 3). Incidences of symptomatic deep vein thrombosis (DVT) and PE, and major or minor bleeding complications were evaluated. Majority of the patients (86%) were assessed to be with standard risks both for PE and bleeding. No patient experienced symptomatic DVT or PE and major bleeding. Eleven percent of the patients discontinued chemoprophylaxis because of bleeding-related wound complication. In conclusion, the 1st AAOS guideline functions successfully in Korean patients undergoing TKA in terms of prevention of symptomatic DVT and PE while avoiding major bleeding complications.

OBJECTIVETo investigate the effects of intermittent pneumatic compression (IPC) on coagulation function, deep venous hemodynamics and prevention of deep venous thrombosis (DVT) of lower limbs in patients after rectal cancer resection.

METHODSA total of 120 patients undergoing rectal cancer resection were randomly divided into non-IPC group (control group, n=60) and IPC group (n=60). The control group received routine treatment after resection and the IPC group received IPC based on the routine treatments. Prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), international normalized ratio (INR) and volume of D-dimer (D-D) were detected before operation and 1-, 3-, 5- and 7-day after operation. Meanwhile, blood flow velocity and caliber of external iliac vein, femoral vein and popliteal vein were examined by color Doppler ultrasound, then the average blood flow velocity and blood flow volume were calculated.

RESULTSIncidence of lower limb DVT was 13.3% (8/60) and 1.7% (1/60) in control group and IPC group respectively with significant difference (P<0.05). The differences in PT, APTT and INR were not significant (P>0.05) at 1-day after operation as compared to the preoperative level, while FIB and D-D both increased (P<0.05), all presented no significant difference among the two groups (P>0.05). PT shortened gradually (P<0.05), APTT and INR did not change significantly (P>0.05), FIB and D-D increased gradually (P<0.05), and no significant differences were found between the two groups at the same time point (all P>0.05). All the above parameters in the control group were significantly lower than those in IPC group (all P<0.05).

CONCLUSIONSIPC can improve hemodynamics indexes of deep veins of lower limb in patients after rectal cancer operation, and prevent the lower limb DVT. IPC is a safe, simple and convenient physical therapy.
