Objective To evaluate and compare the treatment efficacy and safety between catheter-directed thrombolysis monotherapy and catheter-directed thrombolysis combined with percutaneous mechanical thrombectomy for patients with subacute iliofemoral deep vein thrombosis. Methods We conducted a retrospective analysis of a total of 74 subacute iliofemoral deep vein thrombosis patients who underwent catheter-directed thrombolysis with and without percutaneous mechanical thrombectomy. Patients treated with catheter-directed thrombolysis combined with percutaneous mechanical thrombectomy (percutaneous mechanical thrombectomy group, n = 30) or catheter-directed thrombolysis monotherapy (catheter-directed thrombolysis group, n = 44) were included. The primary endpoints were the clinical efficacy rate of thrombolysis, primary patency, and the incidence of post-thrombotic syndrome (at 12 months diagnosed according to the original Villalta score criteria. Secondary endpoints were the total urokinase dose, the thrombolysis time, the detumescence rate and complications. Results The percentage of successful thrombolysis for percutaneous mechanical thrombectomy group was higher than that for catheter-directed thrombolysis group ( P = 0.045). At the 12-month follow-up, there was no difference in the primary patency ( P > 0.05) or the incidence of post-thrombotic syndrome ( P = 0.36). Percutaneous mechanical thrombectomy group had significant advantages in reducing urokinase doses and thrombolysis times compared with catheter-directed thrombolysis group for patients with thrombus clearance levels II and III ( P < 0.05). Conclusion Catheter-directed thrombolysis combined with percutaneous mechanical thrombectomy performs better in removing vein thrombi, reducing urokinase doses, and shortening thrombolysis times.

Summary: Background: This study sought to compare effectiveness and safety of percutaneous mechanical thrombectomy (PMT) and thrombolysis alone (THR) in patients with acute or subacute iliofemoral deep vein thrombosis (IfDVT). Patients and methods: Observational and randomized trials, published between January 2001 to February 2019 were identified by searching MEDLINE. Studies on deep venous thrombosis (DVT) treated with either THR or PMT adjunctive to conventional anticoagulation and compressive intervention were included. Meta-analysis of proportions was conducted to assess effectiveness outcomes of successful lysis and primary patency, post-thrombotic syndrome (PTS), valvular reflux, recurrent DVT, as well as safety outcomes of major bleeding, hematuria, and pulmonary embolism. Results: Of 77 identified records, 17 studies including 1417 patients were eligible. Pooled proportion of successful lysis was similar between groups (THR: 95 % [I2 = 68.4 %], PMT 96 %, [I2 = 0 %]; Qbet [Cochran’s Q between groups] 0.3, p = 0.61). However, pooled proportion of 6-month primary patency was lower after THR than after PMT (68 % [I2 = 15.6 %] versus 94 %; Qbet 26.4, p < 0.001). Considerable heterogeneity within groups did not allow for between-group comparison of PTS and recurrent DVT. Major bleeding was more frequent after THR than after PMT (6.0 % [I2 = 0 %] versus 1.0 % [I2 = 0 %]; Qbet 12.3, p < 0.001). Incidence of hematuria was lower after THR as compared to PMT (2 % [I2 = 56 %] versus 91.3 % [I2 = 91.7 %]; Qbet 714, p < 0.001). Incidences of valvular reflux and pulmonary embolism were similar across groups (THR: 61 % versus PMT: 53 %; Qbet 0.7, p = 0.39 and THR: 2 % versus PMT: 1 %; Qbet 1.1, p = 0.30, respectively). Conclusions: In patients with iliofemoral DVT, percutaneous mechanical thrombectomy was associated with a higher cumulative 6-month primary patency and a lower incidence of major bleeding compared to thrombolysis alone. Risk of hemolysis from mechanical thrombectomy needs further consideration.

Abstract. Background: Rheolytic thrombectomy (RT) for acute iliofemoral deep vein thrombosis (DVT) with first-generation techniques is often incomplete and adjunctive conventional catheter-directed thrombolysis (CDT) is required in more than half of patients to achieve venous patency. Patients and methods: From the prospective Bern Venous Stent Registry, we investigated rates of primary treatment success, primary patency, and post-thrombotic syndrome (PTS) from 40 consecutive patients (mean age 51 ± 19 years, 45 % women) with acute iliofemoral DVT, treated with a novel directional RT technology and stent placement. Overall, 24 patients were treated for native-vessel iliofemoral DVT (11 with single-session RT, 13 with bail-out RT after failed CDT) and 16 for iliofemoral stent thrombosis. Pulse-spray thrombolysis (r-tPA 10 mg) was performed in 29 (73 %) patients. The mean follow-up duration was 193 ± 132 days (minimum 90 days). Results: Overall, primary treatment success of RT was 95 %; only two patients required adjunctive CDT to restore patency. In 24 patients with native-vessel DVT, six-month primary patency was 92 % (95 %CI 75–99 %), and 23 patients (96 %) were free from the PTS according to the Villalta score. In 16 patients with stent thrombosis, six-month primary patency was 63 % (95 %CI 35–85 %) and 50 % were free from PTS. Except for transient macroscopic haemoglobinuria in all patients, no other side effects were recorded. Conclusions: In patients with iliofemoral DVT of native or stented vessels, RT followed by stent placement appears to be effective and safe. The novel technique enables single-session DVT treatment in the majority of patients without the need for prolonged CDT.

Deep vein thrombosis (DVT) is an important cause of short-term mortality and long-term morbidity. Among the different presentations of DVT, thrombus in the iliofemoral veins may be considered the severest form. Although anticoagulation is the mainstay of the management of iliofemoral thrombosis, despite adequate anticoagulant treatment, complications including post-thrombotic syndrome is not uncommon. The latter is often overlooked but can cause considerable morbidity to the affected individuals. Preventing this condition remains a challenge but recent clinical trials of catheter directed thrombolysis and elasticated compression stockings provide some advance in this context. In this article, with the aid of a clinical case, we review the particular considerations to take into account when managing patients with an iliofemoral DVT.

Among patients with proximal iliofemoral deep vein thrombosis (DVT) and an elevated Villalta score, anticoagulation therapy alone may not be a sufficient management strategy in select cases. In this article, we report a case of severe bilateral iliofemoral DVT that resisted the standard treatment for DVT, requiring catheter-directed thrombolysis and subsequent mechanical thrombectomy.

Background Catheter-directed thrombolysis with assisted mechanical thrombolysis is the standard of medical care for proximal deep vein thrombosis. We studied the immediate and intermediate (six months) safety and effectiveness of catheter-directed thrombolysis in patients with proximal lower limb deep vein thrombosis. Methodology Thirty consecutive patients aged between 20 and 70 years with proximal lower limb deep vein thrombosis formed the study group. Catheter-directed thrombolysis was done with streptokinase infuse through a catheter kept in the ipsilateral popliteal vein. Unfractionated heparin was given along with streptokinase. Mechanical thromboaspiration using guiding catheter was performed in addition to thrombolytic therapy. After six months, post-thrombotic syndrome and deep venous patency were assessed by using Villalta scale and duplex ultrasound, respectively. Results Thirty patients with proximal lower limb deep vein thrombosis were treated with catheter-directed thrombolysis. Mean age of the study patients was 41.7 ± 15 years. Mean duration of illness was 13.3 ± 12 days. The mean duration of thrombolysis was 4.5 ± 1.3 days. Grade III (complete) lysis was achieved in 10 (33%) and Grade II (50–90%) lysis in 20 (67%) of patients. Patients with significant residual lesion in Grade II lysis following catheter-directed thrombolysis underwent percutaneous transluminal angioplasty alone (12/20) or venous stenting (8/20). All patients improved clinically following catheter-directed thrombolysis or assisted catheter-directed thrombolysis. Four patients (13%) developed pulmonary embolism during course of hospital stay and among them two (6.5%) patients died. Eleven patients (37%) had minor bleeding or hematoma at local site, and seven (23%) developed anemia requiring blood transfusion and four (13%) patients had thrombocytopenia. After six months, iliofemoral patency was found in 20 (72%) and post-thrombotic syndrome was seen in six (21%) patients. Two (6.5%) patients died during follow-up due to nephrotic syndrome and carcinoma breast. Conclusion Catheter-directed thrombolysis and conventional manual aspiration thrombectomy are an effective treatment for proximal lower extremity deep vein thrombosis with good short and intermediate outcome.
