Successful reconstruction of the infrarenal inferior vena cava and bilateral iliac veins occlusion 27-years after catheter-related thrombosis

Chronic occlusion of the inferior vena cava (IVC) and iliac veins may result from thrombosis associated with central venous catheters in the neonatal period.[1-3]Longstanding iliocaval obstruction leads to significant morbidity, including venous claudication, edema, varicosities, and venous ulceration.[4]Endovascular recanalization has become the treatment of choice, offering high technical success and sustained patency [5].A-27-year old man presented with bilateral lower limb edema, extensive abdominal and limb varicosities, venous claudication, and a chronic ulcer on the right lower extremity.His medical history revealed a premature birth at 28 weeks of gestation and catheter-related thrombosis during a neonatal intensive care unit stay.Computed tomography angiography demonstrated chronic occlusion of the infrarenal IVC and both iliac veins, with patent common femoral veins.Extensive collateral circulation was present in the periaortic, pelvic, and abdominal wall regions.The procedure was performed under general anesthesia.
