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.

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.

A 58-year-old female patient, diagnosed with adenocarcinoma of the lung, underwent percutaneous vertebroplasty at the L4 vertebral body due to painful spinal metastases. Because of deep venous thrombosis of the left femoral and iliac veins, an inferior vena cava filter had been placed before vertebroplasty. Bone cement migrated into the venous bloodstream and then was being trapped within the previously placed filter. This case illustrates that caval filter could capture the bone cement and prevent it from migrating to the pulmonary circulation.

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.

OBJECTIVESTo evaluate the application of inferior vena cava filter (IVCF) in prevention of peri-operative pulmonary embolism in patients with bone fracture combined with deep venous thrombosis (DVT).
METHODSFrom July 2007 to April 2011, 572 cases of bone fractures consequent with DVT that confirmed by Duplex were deployed IVCF to avoid fatal pulmonary embolism in the para-operative period. There were 318 male and 254 female patients with a mean age of (51±23) years (ranging from 16 to 94 years).
RESULTSAll the operations of deployment of the IVCFs were successfully. There were 174 permanent and 399 temporary IVCFs deployed. In all 399 temporary filters, 389 filters were taken out successfully. The mean station time in the IVC of the temporary filters was 22.8 days (7 to 60 days), among which, 118 were found of captured thrombus. After the follow-up of mean 16 months (3 to 40 months) of 566 patients, no pulmonary embolism occurred, but symptomatic DVT were revealed in 15 patients, and the conditions were improved after anticoagulation treatment. No serious complication of post thrombotic syndrome occurred.
CONCLUSIONIVCF deployment can prevent the trauma patients with deep vein thrombosis of fatal pulmonary embolism in the peri-operative period, which may also offer a safe condition to the orthopedic operations.

OBJECTIVETo assess the effectiveness and safety of non-permanent filter in preventing pulmonary embolism (PE) caused by deep venous thromboembolism (DVT).
METHODSThe clinical data of 12 patients who were implanted with non-permanent filter for documented deep venous thromboembolism in Peking Union Medical College Hospital from September 2003 to June 2006 were retrospectively analyzed.
RESULTSAmong these 12 patients, 10 were implanted with temporary filters, and 2 with retrievable filters. All the 12 operations were successful without major complications. In the 10 patients who received temporary filters, filters were smoothly removed after 4 weeks in 9 patients, while one patient was further treated with anticoagulation therapy for 12 weeks because large emboli were entrapped by filter. In the 2 patients who received retrievable filters, filter were smoothly removed 2 weeks later in one patient; however, in another patient, the filter was left inside because large emboli were entrapped by filter. In all the 12 patients, emboli were entrapped in 6 filters (50%), in which the emboli were larger than 2 cm in 2 patients, larger than 1 cm but less than 2 cm in 1 patient, and less than 1 cm in 3 patients. PE scanning was performed in 10 patients before primary implantation, and PE was found in 5 patients. PE scanning was performed in 8 patients 6 months after implantation, and minor PE was found in 4 patients, whose symptoms and affected pulmonary artery were obviously improved. All patients received regular follow-up (ranged from 3 months to 2 years), 1 patient died of malignant tumor 4 months after operation, 1 patient suffered inferior vena cava occlusion due to large emboli entrapped by the temporary filter, and 1 patient experienced the recurrence of symptomatic DVT. Symptoms were improved in all the 5 patients with PE.
CONCLUSIONSNon-permanent filter can safely and effectively protect patients from PE. More standardized criteria for placement and protocols to ensure timely removal should be developed and implemented.

OBJECTIVETo discuss the efficacy of anticoagulation on patency post-permanent inferior vena caval filter (IVCF) placements.
METHODSThe patients with deep vein thrombosis (DVT) of the lower extremity who were accepted permanent IVCF placement from December 2001 to December 2007 were reviewed retrospectively. Data on vital status, filter thromboembolism, anticoagulation time, and so on were obtained through follow-up. One hundred and thirty eight patients (75 male and 63 female) with a mean age of 65 years were enrolled in the study. All the patients were divided into non-anticoagulation group, anticoagulation group A with taking warfarin less than 6 months, or anticoagulation group B with taking warfarin more than 6 months. chi(2) test, t test, Kaplan-Meier survival curve, Log-rank test were used for statistics analysis.
RESULTSSixteen patients died, and 1 of them died of pulmonary embolism. Including the 1 patient mentioned before, there were 19 patients (13.8%) suffered from filter thromboembolism. Upon chi(2) test, there were no significant differences (P = 0.288) on the patency rates between non-anticoagulation, anticoagulation group A and anticoagulation group B (87.8%, 75.0%, and 88.3% respectively). Upon Kaplan-Meier survival analysis, there were still no significant differences (P = 0.227) on the mean patency time and the cumulate rates of patency at the 1st or 3rd year between the 3 groups (87.1%, 80.0%, 94.8% and 87.1%, 74.3%, 85.4% respectively).
CONCLUSIONAnticoagulation has no efficacy on patency post-permanent IVCF placements.

OBJECTIVETo investigate the effects of the different treatments of deep venous thrombosis (DVT) of lower extremities on the incidence of the pulmonary embolism (PE).
METHODS201 patients (97 males and 104 females, mean age 60.4 years ranged from 24 to 83) from August 2002 to June 2008 with DVT were retrospectively reviewed and divided into 3 groups based on different treatment, including anticoagulants plus thrombolytics alone (group 1), thrombectomy plus anticoagulants plus thrombolytics (group 2) and anticoagulants plus thrombolytics after delivery of inferior vena cava (IVC) filter (group 3) respectively. One hundred and seventy-four cases had left lower limb DVT, 24 cases had right lower limb DVT and 3 cases had both sides of lower limb DVT. Different incidence of PE in different period (7-14 d in hospital and follow-up after discharge) were calculated. Effects of the three different treatment methods of DVT on the incidence of PE were studied.
RESULTSFor in-patients, the prevalence of symptomatic PE was 2.8% (3/107) in the group of receiving anticoagulants plus thrombolytics alone, but in the other two groups, no symptomatic PE happened. There was no significant difference in incidence of symptomatic PE among the 3 groups (P=0.425). For patients discharged, after 6 to 72-month follow-up (mean 24-month), we found that no PE happened in group 1 and group 2, while in group 3, the incidence of PE was 2.4% (1/42). There was also no significant difference (P=0.656) among 3 groups.
CONCLUSIONSThere is no significant difference in relation to the incidence of PE in these 3 groups. Therefore vena cava filter implantation should be restricted to optimal indication.
