Background: The purpose of this study was to assess the safety and efficacy with midterm outcomes of pharmacomechanical thrombectomy (PMT) performed by using a relatively new thrombectomy device in the treatment of lower extremity deep vein thrombosis (DVT). Methods: Between February 2014 and February 2016, a total of 46 patients with lower extremity DVT were treated with PMT by using Cleaner rotational thrombectomy system. Preprocedural, intraprocedural, postprocedural, and follow-up records of patients were collected and retrospectively analyzed. Results: Mean age of patients was 50.5 (14.8) years, and 58.7% of them were female. Technical success rate of procedure was 91.3%. Mean procedure time was 81.8 (40.3) minutes. Early clinical improvement was observed in all patients with successful treatment. No serious adverse event related to procedure and mortality was observed. Mean follow-up time was 16.0 (7.9) months. Reocclusion was observed in 7 (17.5%) patients during the follow-up period. Venous patency rates of patients at 1-, 3-, 6-, and 12-month follow-up visits were 95%, 92.5%, 89.7%, and 79.5%, respectively. Mild, moderate, and severe postthrombotic syndrome were observed in 8 (20%) patients, 4 (10%) patients, and 1 (2.5%) patient, respectively. Postthrombotic syndrome–free survival rate was 67.5%. Conclusion: Cleaner rotational thrombectomy system appears to be safe and effective in the treatment of lower extremity DVT. Further larger randomized studies are needed to determine the long-term outcomes of this treatment modality.

Hemolysis Rate

Abstract Percutaneous mechanical thrombectomy (PMT) is an efficient way to treat the deep vein thrombosis (DVT). During the course of treatment, blood cell will be destroyed by the component of thrombectomy device, causing hemolysis. In this research, the computational fluid dynamics (CFD) methodology is used to investigate hemolysis effect of rotary cutting thrombectomy device. And a prototype of rotary cutting thrombectomy device is made to carry out two corresponding experiments to verify the simulation results. CFD results indicate that the hemolysis rate increases significantly with the rise of rotation speed of cutting component. The experimental results are in good consistence with the CFD results, and shows that the longer the working time, the higher the hemolysis rate. Thus a rotation speed between 5,000 rpm and 10,000 rpm can be considered reasonable. The results can be served as a helpful guidance for the design of such thrombectomy devices.

Objectives: This paper documents our experience and outcomes of using a relatively new endovascular rotational thrombectomy device for salvage of thrombosed vascular access. Methodology: A retrospective study reviewing patients with thrombosed native AVF or AVG who underwent endovascular declotting using a rotational thrombectomy device between November 2018 and May 2020 at a tertiary university hospital in Southeast Asia. We evaluated demographics, procedural data, technical and procedural success, patency rates and complications. Results: A total of 40 patients underwent single session endovascular declotting of thrombosed vascular access. The mean follow-up period was 21.6 months (range 13.4–31 months). The technical success was 92.5% and clinical success was 80%. About 50% of patients had concomitant thrombolysis for pharmacomechanical thrombectomy. One patient had a myocardial infarction during the post-operative period. There were no other major complications within 30 days. The primary patency was 45.5% at 6 months and 22.7% at 12 months. Assisted primary patency was 68.1% at 6 months and 61.6% at 12 months, which was maintained up to 2 years. The secondary patency was 84.1% at 6 and 12 months. Conclusion: Our study shows that rotational thrombectomy device for single session thrombectomy of thrombosed arteriovenous fistulas and grafts is safe and effective. A high technical and clinical success rate was achieved, with low complication rates and specific advantages compared to other techniques, including reduced length of hospital stay. Our reported mid-term outcomes are reasonable with an assisted primary patency of 62% at 12 and 24 months. The use of newer techniques and novel dedicated thrombectomy devices show promise.

Purpose: To evaluate a rotational thrombectomy device in the treatment of acute and subacute/chronic thrombotic infra-aortic occlusions of native vessels and bypass grafts. Methods: From July 2000 to February 2002, 98 patients (65 men; mean age 66±9 years, range 47–90) with 100 thrombotic occlusions (mean age of occlusion 31±33 days, range 0–140) measuring an average of 21±11 cm long (range 2–40) were treated with rotational thrombectomy (Rotarex). There were 33 acute (≤14 days) thrombotic/embolic native artery occlusions (group I), 58 subacute/chronic (>14 days) native artery occlusions (group II), and 9 acute bypass graft occlusions (group III). Results: The device activation time was 4.9±1.4 minutes, during which 4.0±1.4 passes of the device were performed. The amount of aspirated fluid was 240±119 mL. Slightly less than half the arteries (48%) were stented. Primary success (residual stenosis <30%) was achieved in 92% (94% for group I, 93% for group II, and 78% for group III; 100% for the ipsilateral approach, 56% for the crossover approach). Among the 18 complications, 3 were serious (2 amputations after unsuccessful intervention and 1 death); there were 8 vessel perforations and 7 cases of peripheral embolization. Thirty-day survival and limb salvage was 88% for group I, 100% for group II, and 66% for group III. Conclusions: The device is an easy-to-handle, useful tool for ipsilateral treatment of acute and subacute thrombotic arterial and bypass graft occlusions. The use of this device is limited by the 8-F diameter of the catheter and the limited capacity for crossover interventions.
