Single-Stage Endovascular Thrombectomy and Stenting as the First-Line Strategy in the Treatment of Phlegmasia Cerulea Dolens Caused by Iliac Vein Lesions

Background: Phlegmasia cerulea dolens (PCD) is a rare and serious complication of deep venous thrombosis and iliac vein lesions (IVLs) are the most common cause of PCD. The pur -pose of this study was to explore the safety and efficacy of single-stage endovascular thrombus removal and stenting to treat PCD caused by IVLs.Methods: Clinical data of 13 patients with PCD secondary to IVL were retrospectively analyzed. They underwent endovascular thrombus removal, including rheolytic thrombectomy, manual aspiration thrombectomy, and simultaneous iliac vein stenting after thrombus removal. The safety and efficacy of single-stage endovascular thrombectomy and stenting in the treatment of PCD were evaluated.Results: The technical success rate was 100% (13/13). Postoperative symptoms were signifi-cantly relieved in all patients. There were no perioperative major bleeding complications or other critical adverse events. Two (15.4%) patients had slightly elevated serum creatinine concentra-tion after surgery, which returned to normal before discharge. At the 12-month follow-up, the stent primary patency rate was 81.8% and there were no cases of severe post-thrombotic syndrome.Conclusions: Single-stage endovascular thrombectomy and stenting in PCD due to IVLs was minimally invasive, safe, and effective; it is recommended as a first-line treatment for PCD caused by IVLs.
