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 observe preventive effect of Caprini based thrombosis risk evaluation model on venous thromboembolism (VTE) after total knee replacement (TKA). METHODS: Totally 257 TKA patients were admitted from May 2017 to December 2021 were selected. They were divided into conventional intervention strategies (121 patients in control group) and intervention strategies based on Caprini thrombosis risk evaluation model (136 patients in observation group), based on whether Caprini thrombosis risk evaluation model was introduced in May 2019. In normal gourp, there were 79 males and 42 females aged from 50 to 78 years old with an average of (63.10±11.86) years old;body mass index (BMI) ranged from 19 to 32 with an average of (25.21±4.95) kg/m2;55 patients on the left side and 66 on the right side. In observation group, there were 81 males and 55 females aged from 50 to 78 years old with an average of (64.35±10.54) years old;BMI ranged from 19 to 32 with an average of (24.43±5.18) kg/m²;87 patients on the left side and 49 on the right side. The incidence of VTE, visual analogue scale (VAS), Hospital for Special Surgery (HSS) score, affected limb swelling, mean velocity(Vm), peak velocity (PV), D-dimer (D-D), prothrombin time(PT), and incidence of complications were analyzed and compared. RESULTS: The incidence of VTE in observation group was 1.47%(2/136), and 9.09%(11/121) in control group, and there was statistically difference between two groups (χ²=6.976, P=0.008). At 7 days after operation, VAS, HSS score and the difference in circumference of the affected limb in observation group were significantly better than those in control group, and had statistically differences (P<0.05). Blood flow Vm and PV levels between two groups were significantly increased (P<0.001), and blood flow Vm and PV levels in observation group were significantly higher than those in control group on the 7th day after operation, and had differences (P<0.001). The serum D-D level in observation group was significantly lower than that of in control group on the 7th day after operation, and PT level was significantly higher than that of in control group, and had difference(P<0.05). There was no difference in total incidence of complications between two groups (χ²=4.488, P=0.034). CONCLUSION Intervention strategy based on caprini thrombus risk evluation model could effectively reduce incidence of VTE and complications in TKA patients, improve swelling, hemodynamics and coagulation function of the affected limbs, and contribute to recovery of knee joint function.

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.

This study was undertaken to determine the prevalence and the natural course of venous thromboembolism (VTE) without thromboprophylaxis to ascertain whether routine thromboprophylaxis is necessary following unicompartmental knee arthroplasty (UKA) in Korean patients. The medical records and multidetector row computed tomography (MDCT) imaging of the consecutive 77 UKAs in 70 patients were reviewed. In all patients, MDCTs were undertaken preoperatively and at 1-week after surgery, and VTE symptoms were evaluated. At postoperative 6-months, follow-up MDCTs were undertaken in all patients in whom VTEs were newly detected after surgery. VTE lesions were newly detected in 18 (26%) of the 70 patients. However, none of the patients complained of VTE-related symptoms and MDCT demonstrated that all VTEs were small and involved limited portion without lower leg edema or pleuroparenchymal complication. At the 6-month follow up MDCT, all types of VTEs were shown to be completely resolved, regardless of their location. All of the VTE lesions maintained an asymptomatic status for 6-month after surgery. VTE following UKA in Korean patients who do not receive thromboprophylaxis seems to occur frequently, but all of the VTEs are clinically insignificant and all VTEs are spontaneously regressed. Routine thromboprophylaxis or thrombolytic treatment in Korean patients undergoing UKA may not be necessary.

Intermittent Pneumatic Compression (IPC) device has been used to prevent venous thromboembolism (VTE). This study investigated the effectiveness of IPC device. We evaluated incidences of deep vein thrombosis (DVT) and pulmonary embolism (PE) in total hip arthroplasty (THA) patients after use of IPC device, and compared with historical incidences from our institution. We applied IPC device in 741 patients who underwent 870 elective primary THAs from January 2010 to December 2013, DVT was detected in 3 patients (0.3%) by sonography, and one (0.1%) of them was symptomatic. Symptomatic PE occurred in 1 patient (0.1%) and there were no cases of fatal PE. The incidence of symptomatic DVT was significantly lower than the historical control (P = 0.042). The IPC is a safe and effective prophylaxis of VTE after primary THA in Korea.

Although inflammatory bowel disease (IBD) is a chronic disorder that mainly affects the gastrointestinal tract, extraintestinal complications can occur in IBD patients. Among many extraintestinal complications, venous thromboembolism (VTE) is particularly a feared complication due to its significant morbidity and mortality. IBD patients have about 2 to 3 fold higher risk of developing VTE compared with the general population, and the current management guidelines for IBD patients propose recommendations for the prevention of VTE. This review aims to summarize clinical characteristics of VTE in IBD patients and to outline strategies for preventing and treating VTE in these patients.

OBJECTIVETo evaluate the efficacy and safety of three antithrombotic agents on venous thromboembolism (VTE) after unilateral total knee arthroplasty.

METHODSFrom November 2011 to March 2014, 149 patients undergoing unilateral total knee arthroplasty for knee osteoarthritis were reviewed. Among them, there were 66 males and 83 females, ranging in age from 48 to 76 years old. All the cases were randomly divided into three groups including Aspirin group, low-molecular-weight heparin (LMWH) group, and rivaroxaban group, according to antithrombotic agents. Deep vein thrombosis (DVT), pulmonary embolism (PE) and bleeding complication (including wound ecchymosis, hematoma and other local complications, gastrointestinal, cardiovascular, urinary hemorrhage and other major bleeding events) of antithrombotic agents were observed and analyzed statistically at the 6 week, 8 week, and 12 week after operation.

RESULTSAmong patients who received Aspirin (48 cases), 4 patients had DVT, in 1 patient had PE, and 2 patients had bleeding complication. Among 54 patients in low-molecular-weight heparin group, 3 patients had DVT, 1 patient had PE, and 3 patients had bleeding complication. While among those patients received the rivaroxaban (47 cases), 3 patients had DVT, 0 patient had PE, and 11 patients had bleeding complication. There were no statistically differences among three groups on DVT, and PE (P>0.05). The incidence of bleeding complication in rivaroxaban group was higher than the other two antithrombotic agents, and the difference among the three groups was statistically significant (P<0.05).

CONCLUSIONAspirin, low-molecular-weight heparin, and rivaroxaban could effectively reduce the incidence of VTE after total knee arthroplasty, and their efficacy was similar. Rivaroxaban has a higher incidence of bleeding complication and further clinical trials are required to be conducted to assess the safety of rivaroxaban in clinical.

In 2010, we proposed the first Korean Guidelines for the Prevention of Venous Thromboembolism (VTE). It was applicable to Korean patients, by modifying the contents of the second edition of the Japanese guidelines for the prevention of VTE and the 8th edition of the American College of Chest Physicians (ACCP) evidence-based clinical practice guidelines. From 2007 to 2011, we conducted a nationwide study regarding the incidence of VTE after major surgery using the Health Insurance Review and Assessment Service (HIRA) database. In addition, we have considered the 9th edition of the ACCP Evidenced-Based Clinical Practice Guidelines, published in 2012. It emphasized the importance of clinically relevant events as opposed to asymptomatic outcomes with preferences for both thrombotic and bleeding outcomes. Thus, in the development of the new Korean guidelines, three major points were addressed: 1) the new guidelines stratify patients into 4 risk groups (very low, low, moderate, and high) according to the actual incidence of symptomatic VTE from the HIRA databases; 2) the recommended optimal VTE prophylaxis for each group was modified according to condition-specific thrombotic and bleeding risks; 3) guidelines are intended for general information only, are not medical advice, and do not replace professional medical care and/or physician advice.

OBJECTIVEThe aim of this study was to compare the efficacy of low molecular weight heparin (LMWH) combined with graduated compression stockings (GCS) with GCS alone as prophylactic measures for venous thromboembolism (VTE) in post-operative patients with gynecologic cancer.

METHODSPatients diagnosed with gynecologic cancer undergoing primary major surgery between 2010 and 2011 in our institute were randomized to receive LMWH+GCS or GCS as VTE prophylaxis post-operatively.

RESULTSAltogether 247 patients were enrolled. The incidence of VTE in patients treated with LMWH + GCS was significantly lower than that in patients using GCS alone (0.8% Vs. 8.1%, P = 0.01). There were no severe bleeding complications in the patients with prophylactic use of LMWH and the occurrence rate of wound dehiscence was comparable between the two groups (P > 0.05). Multivariable logistic regression analysis revealed that age over 60 years (P = 0.015) , duration of operation over 3 hours (P = 0.04) and without prophylactic use of LMWH (P = 0.02) were independent risk factors for VTE.

CONCLUSIONSDual prophylaxis with LMWH and GCS should be recommended for gynecologic cancer patients undergoing major surgery for its better efficacy than GCS. Prophylactic use of LMWH is safe and convenient. Patients with older age and prolonged operation time are at highest risk of developing VTE post-operatively.
