[Endovascular repair of iliocaval arteriovenous fistula complicating lumbar disc surgery]. / Traitement endovasculaire d'une fistule artério-veineuse ilio-cave compliquant une chirurgie discale lombaire.

Vascular complications of lumbar disc surgery are rare. Few cases have been reported. Arteriovenous fistulas are the most common. They are due to anatomical relationships between the last lumbar vertebrae, the corresponding discs, and the iliac vessels; degenerative lesions of the intervertebral discs facilitate instrumental vessel perforation, and operative difficulty. Computed tomography is particularly accurate for making the diagnosis. Treatment strategies consist in surgery or endovascular management. Percutaneous endovascular treatment using a stent-graft is a reasonable option for treating arteriovenous fistula. We describe the case of a 50-year-old patient who developed an iliocaval arteriovenous fistula following lumbar disc hernia surgery. The lesion was excluded by a stent-graft. The postoperative period was uneventful.

[Thrombosis of an aorto-iliac stent graft used for treating an iliocaval arteriovenous fistula following lumbar disc surgery]. / Thrombose d'une endoprothèse couverte aorto-bi-iliaque posée en cure d'une fistule artério-veineuse après chirurgie discale lombaire.

OBJECTIVES: Major vessel injury is a rare complication of spinal surgery. Iliac artery injury is the most common. Frequently, a chronic arteriovenous fistula develops. METHODS: We describe the case of a 63-year-old woman who had developed a chronic arteriovenous fistula following lumbar disc hernia surgery. The patient was treated using an Anaconda™ stent graft (Vascutek Terumo). After 2years, the prothesis thrombosed and an aorto-iliac bypass was performed. RESULTS: A gel soft prosthesis 18/9 (Vascutek Terumo) was implanted by laparotomy. The postoperative period was uneventful. A month later, the patient had recovered good lower limb function. CONCLUSION: The choice between endovascular versus open surgery must take into account the patient's age, the risk of long-term complications, and the need for radiographic surveillance. Curative open surgery remains a valid option for young patients.
