Successful Management of Spontaneous Iliac Vein Rupture with Double Bare Stent Technique: A Case Report and Review of Literature.

Spontaneous rupture of the iliac vein is a rare cause of retroperitoneal hematoma. A misdiagnosis may delay the treatment and consequently put the patient in a life-threatening emergency. We report the case of a 73-year-old woman who presented with hemorrhagic shock from bleeding caused by a large left retroperitoneal hematoma. She was successfully treated with an endovascular approach by using a double bare stent technique. An extensive review of the literature was conducted and a total 44 articles with 50 patients were identified. Among these patients, 88.2% were women, 94.1% presented with a left-sided rupture, and the mortality rate was 13.7%. Spontaneous iliac vein rupture was more likely to occur in the left side in female patients. Conservative treatment was an option in hemodynamically stable patients. Exploratory laparotomy and surgical iliac vein repair was necessitated in most patients. Endovascular treatment including placement of covered stent and coil embolization had been widely used to treat spontaneous vein rupture since 2003. Double bare stent technique was also an effective alternative if a suitable covered stent was unavailable.
