[Surgical treatment of left iliac compression syndrome]

To explore the remedial indications, operational methods, and perioperational treatment of iliac compression syndrome (ICS) in left extremity.

The clinical data of 46 patients with symptoms of chronic swelling or varicose vein in left lower extremity and the diagnosis of left ICS were analyzed. Interventional treatment, iliac vein loosening by laparotomy and right iliac artery anastomosis behind left iliac vein lesion, and vascular graft orthotopic transplantation were performed in 32, 8 and 6 cases respectively. Surgical management of saphenous vein and femoral valves were performed simultaneously or by secondary operation in 41 cases. 36 patients were complicated by acute left lower extremity deep venous thrombosis (DVT), of which resection of lesion in left iliac vein and vascular graft orthotopic transplantation after thrombectomy, and iliocaval bypass were performed in 25 and 11 cases respectively. After treatment, the patients were followed up for 6 - 66 months.

No operation death and acute pulmonary embolism was found among the patients. The treatment showed a good long-term effect.

Lesions of left iliac vein are the important cause of swelling and varicose veins and acute DVT in left lower extremity and should be managed as early as possible. Interventional treatment and surgery are effective.
