The short-term outcome of residual thrombus of the lower extremity after pharmacomechanical catheter-directed thrombolysis for deep vein thrombosis

Impact of concomitant popliteal vein thrombosis in patients with acute iliofemoral deep vein thrombosis treated with endovascular early thrombus removal

Summary: Background: Catheter-based thrombus removal (CBTR) reduces the risk of moderate to severe post-thrombotic syndrome (PTS) in patients with acute iliofemoral deep vein thrombosis (IF-DVT). However, the impact of concomitant popliteal DVT on clinical and duplex sonographic outcomes is unknown. Patients and methods: In this post-hoc analysis including the entire cohort of the randomized controlled BERNUTIFUL trial (48 patients), we compared clinical (incidence/severity of PTS assessed by Villalta score and revised venous clinical severity scores, rVCSS), disease-specific quality-of-life (QOL, CIVIQ-20 survey) and duplex sonographic outcomes (patency, reflux, post-thrombotic lesions) at 12 months follow-up between patients with IF-DVT with and without concomitant popliteal DVT treated by CBTR. Results: Overall, 48 IF-DVT patients were included (48% men, median age of 50 years), of whom 17 (35%) presented with popliteal DVT. At baseline, patients with popliteal DVT were older, had a higher body mass index and more important leg swelling. At 12 months, freedom from PTS (93% vs 87%, P=0.17), median total Villalta score (1 vs 1.5; P=0.46), rVCSS (2 vs 1.5, P=0.5) and disease-specific QOL (24 points vs 24 points, P=0.72) were similar between patient with and without popliteal DVT, respectively. Duplex sonographic outcomes were similar, except for more frequent popliteal post-thrombotic lesions and reflux (P=0.02) in patients with popliteal DVT. Conclusions: Relevant clinical outcomes 1 year after successful CBTR were favorable, regardless of the presence or absence of concomitant popliteal DVT. However, post-thrombotic popliteal vein lesions and reflux are more frequent in IF-DVT patients with popliteal involvement. Their impact on long-term outcomes remains to be investigated.

Application of CT Scan in Diagnosis of Iliac-Femoral Vein Thrombosis after Hip Replacement

Based on the knowledge of the previous film, the CT scan was used to diagnose the disease of women and men after the diagnosis of atherosclerosis by scanning the CT microscope. This article first examines the existing medical procedures in China, highlighting the advantages and disadvantages of various systems in terms of usability and user experience. Combined with the actual needs of hospitals, this paper developed a set of preoperative intelligent measurement system (MIPS) based on pattern recognition for total skeletal joint replacement. It is beneficial for doctors to better observe the lesions of patients before surgery and carry out necessary operations in the PATIENT DR film. In the process, the model is used to identify the patient, and the patient is given a fake score based on the characteristics of the DR film. In nonsymptomatic patients, 13.5% had muscle contraction > 50%, 2.0% had muscle contraction 70%, and the mean pelvic area was 23.48%. The left ventricular muscle has a 45.0% contraction rate, the left ventricle has a 70% contraction, and the median contraction rate is 47.58%. The right muscle, which is inserted between the right artery and the inner lymphatic artery, is the most common type of compression of the right muscle, accounting for 59.26%. In terms of the mean muscle contraction rate on the right side, patients with DVT with right muscles were higher than patients with DVT with left ventricles (48.54% to 22.29%, P < 0.001). The mean incidence of left ventricular DVT patients was higher than that of right ventricular DVT patients (71.88% versus 45.83% P < 0.0011).
