A retrospective study on endovascular management of iatrogenic vascular injuries.
VASCULAR(2012)
Abstract
The purpose of this study was to evaluate the outcome of endovascular management of iatrogenic vascular injuries (IVIs). We retrospectively reviewed the clinical records of 19 consecutive patients who underwent endovascular therapy of IVIs. Endograft implantation was conducted in 13 patients, intravascular embolization using coil was performed in four patients, combined treatment involving endovascular balloon intervention and percutaneous thrombin injection was done in one patient and the remaining one patient received balloon compression for hemostasis. There were no deaths after the operation. In the patients with vessel rupture (n=9) or perforation (n=4), cessation of bleeding and restoration of blood flow were achieved following the endovascular treatments. Four cases of pseudoaneurysm and one case of arteriovenous fistula were successfully eliminated. At a median follow-up of 23.8 months (range 4-84), one patient suffered a mild cerebral infarction secondary to covered stent placement and one patient developed a partial renal infarction secondary to coil embolization. Additionally, stent collapse was found in one patient with stenosis of the iliofemoral vein, accounting for the failure to resolve the lower limb edema. In conclusion, endovascular therapy is an effective technique in the management of different types of IVIs, but is associated with minor ischemic complications.
