A case report of successful intravascular shockwave lithotripsy and ad hoc directional venous atherectomy of extensive chronic femoral deep venous thrombosis

BACKGROUND: Conventional treatment for chronic deep venous thrombosis (DVT) is anticoagulation. However, limited interventional endovascular options exist for patients with non-healing venous ulcers secondary to chronic DVT. CASE SUMMARY: We present a case of 67-year-old man with severely symptomatic post-thrombotic syndrome (PTS) with persistent high-grade femoral DVT despite prior compressive therapy and chronic oral anticoagulation. It has been successfully treated with intravascular shockwave lithotripsy and ad hoc directional venous atherectomy facilitating subsequent mechanical thrombectomy and venoplasty. The procedure was without complication and resulted in significant clinical improvement. DISCUSSION: We believe our novel endovascular interventional approach represents a unique modality of intervention for patients with chronic DVT and PTS resistant to conventional venoplasty.
