Insights
Deep venous stenting treats post-thrombotic syndrome, but stent thrombosis can occur. Mechanical thrombectomy using the RevCore System successfully restored stent patency in a chronic thrombosis case.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Endovascular Therapy
Background:
- Deep venous stenting is a common treatment for post-thrombotic syndrome.
- Stent thrombosis is a complication leading to symptom recurrence.
- Limited options exist for restoring stent patency after thrombosis.
Observation:
- A 50-year-old male with prior iliocaval reconstruction presented with recurrent left lower extremity swelling.
- This was due to occlusion of his left external iliac and common iliac vein stents.
- The patient underwent mechanical thrombectomy with the RevCore System and angioplasty.
Findings:
- Following the procedure, the patient showed widely patent bilateral iliac vein stents.
- Complete resolution of his symptoms was observed one month later.
- The RevCore System proved effective for chronic in-stent thrombosis.
Implications:
- Mechanical thrombectomy with the RevCore System is a viable option for managing chronic deep venous stent thrombosis.
- This approach can lead to durable stent patency and symptomatic improvement.
- Further investigation into the RevCore System's efficacy in similar cases is warranted.
Abstract:
In recent years, deep venous stenting has increasingly become a treatment strategy for post-thrombotic syndrome. Stent thrombosis can occur, resulting in symptom recurrence despite medical therapy, and there are few options available for durable stent patency restoration. We present a case of a 50-year-old male with prior iliocaval reconstruction that experienced recurrent left lower extremity swelling secondary to occlusion of left external iliac and common iliac vein stents during follow-up. Mechanical thrombectomy with the RevCore System and angioplasty was performed. One month later, the patient demonstrated widely patent bilateral iliac vein stents and complete symptomatic resolution. The RevCore System is a feasible alternative for treatment of chronic in-stent thrombosis.

The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...
