The present study was conducted to evaluate this issue. The study of prevalence and risk factors of postoperative lower limb deep vein thrombosis (DVT) in Thai gynecologic patients was limited. The Thrombus diameter has a significant effect on the natural course of ICMVTs, especially with diameter larger than 0.6 cm. Thrombus diameter, thrombus length, FIB, and D-dimer were four independent risk factors of non-completely dissolved ICMVTs. Multivariate analysis revealed that thrombus diameter over 0.6 cm (odds ratio, 8.900 95 % confidence interval : 3.623-21.865), thrombus length over 5.0 cm (OR, 3.904 95 % CI, 1.121-13.603), FIB over 3.0 g/L (OR, 3.627 95 % CI, 1.356-9.689), and D-dimer over 1.0 mg/L (OR, 2.602 95 % CI, 1.075-6.296) were four independent risk factors of non-completely dissolved ICMVTs.Ĩ5.8 % of ICMVT was tending to disappear at the third months after ORIF for closed intra-articular DFFs. There existed 14 cases (10.0 %) without change on the size and 6 cases (4.2 %) with proximal propagation. At the follow up of 3 months,120 cases was tending to disappear with 88 cases(62.9 %) completely dissolved and 32 cases(22.9 %) partly dissolved. The postoperative ICMVTs was diagnosed at 5.47 ± 2.46 days after ORIF for closed intra-articular DFFs. Multivariable analysis was performed to evaluate the relationship between the resolution of ICMVT three months postoperatively and risk factors including age, Body Mass Index (BMI), gender, thrombosis length (> 5 / ≤5 cm), thrombosis diameter(> 0.6/≤0.6 cm), and thrombosis-related biochemistry indices. Sonography was used to evaluate the resolution of muscular vein thrombosis at the time point of the third month postoperatively and the results were compared between the two time points. There were 29 males and 111 females with the average age of 70.16 ± 8.75 years old. After the administration of antithrombotic agents immediately after diagnosis, the location and prognosis of postoperative ICMVT were examined by Duplex ultrasonography (DUS) with a three-month follow-up. From August 2018 to August 2020,a total of 140 patients with flesh ICMVT after ORIF for closed intra-articular DFFs were collected during hospitalization. The study was designed as a prospective clinical cohort study at our hospital. To observe the outcome of isolated calf muscle vein thrombosis (ICMVT) undergoing open reduction and internal fixation (ORIF) for closed intra-articular distal femur fractures (DFFs) and to analyze related factors. Lethal thromboemboli would occur at proximal veins as a result of proximal propagation from calf DVTs. SV is considered to be the primary site of DVT the DVT then propagated to proximal veins through the drainage veins. Proximal tips of fresh thrombi were mainly located in the popliteal vein and tibioperoneal trunk, occurring in these locations in 63% of limbs. The incidence of DVT gradually decreased according to the drainage route of the central SV. SV showed the highest incidence of DVTs in eight venous segments. Fresh and organized thrombi were detected in 84% of patients. CV was involved in all limbs with DVT with isolated calf DVTs were seen in 47% of patients. The CV was subdivided into two subgroups, drainage veins of the soleal vein (SV) and non drainage veins of SV.Įighty-nine patients had bilateral limb DVTs. Venous segments were classified into three groups: iliofemoral vein, popliteal vein and calf vein (CV). The distribution and chronology of DVT in each deep venous segment were examined.
We investigated 100 autopsy cases of PE from limb DVT. To clarify the histopathological characteristics of deep vein thrombosis (DVT) resulting in lethal pulmonary thromboembolism (PE).
