Successful treatment of phlegmasia cerulea dolens with combination surgical and catheter-assisted thrombectomy.

Phlegmasia cerulea dolens is a rare condition caused by complete venous occlusion that leads to impaired arterial flow. Prompt diagnosis and treatment initiation are paramount in preventing progression to gangrene, the need for amputation, and possibly the death of the patient. Thrombolysis or surgical thrombectomy, for advanced disease and cases in which anticoagulation is contraindicated, represent the current standard treatment. Here we report the case of a 47-year-old male who sustained severe trauma during a car accident. After having a prophylactic retrievable inferior vena cava filter placed, he developed caval thrombosis with progression to phlegmasia cerulea dolens. He was successfully treated with a combination of surgical thrombectomy of the lower extremity veins and catheter-assisted thrombectomy of the iliac veins and inferior vena cava, in the setting in which an initial attempt at balloon thrombectomy of the iliac veins and inferior vena cava failed. He was discharged from the hospital in stable condition and on follow-up visits had full resolution of symptoms. Ultrasound evaluation showed no residual venous clot. The presented case illustrates how the use of catheter-assisted thrombectomy alleviated the need for a laparotomy and direct caval evacuation of the thrombus and provided a timely and effective treatment of phlegmasia cerulea dolens with impending gangrene.
