Iliofemoral Venous Thrombosis Caused by Compression of an Internal Iliac Artery Aneurysm: A Minimally Invasive Treatment

The Successful Treatment of an Ilio-Iliac Fistula and Aneurysms Affecting the Abdominal Aortic and Iliac Arteries via Endovascular Stent Graft Repair

Spontaneous ilio-iliac arteriovenous fistula (AVF) associated with aneurysms affecting the abdominal aortic and iliac arteries is a rare condition. The classical clinical symptoms of ilio-iliac AVF include high-output heart failure, abdominal pain, abdominal bruits and thrills, a pulsatile abdominal mass, and venous congestion symptoms (leg edema and hematuria). The prompt repair of AVF is necessary to restore the patient's hemodynamics. We report a case in which a patient with aneurysms affecting the abdominal aortic and iliac arteries and an ilio-iliac AVF presented with high-output heart failure and leg ischemia and was successfully treated via endovascular stent graft repair.

A Rare Presentation of an Isolated Internal Iliac Artery Aneurysm: Report of a Case and Literature Review

Isolated internal iliac artery aneurysms (IIIAAs) are extremely rare. We present the case of a 75-year-old white Caucasian male patient admitted for right lower limb deep venous thrombosis and low-risk pulmonary embolism due to the compression of the external iliac vein from an IIIAA. A review of the literature was also performed to identify the epidemiologic, clinical characteristics and diagnostic and operative strategies of this disease. At present, a recommendation for the best operative strategy in the presence of an IIIAA is difficult. Our analysis demonstrated controversial results, but we are confident to recommend the endovascular treatment in an elective setting.

Sequential coil embolization of bilateral internal iliac artery aneurysms prior to endovascular abdominal aortic aneurysm repair

PURPOSE

To report the endovascular repair of concomitant aneurysms of the abdominal aorta and both internal iliac arteries.

CASE REPORT

A 72-year-old man with a 5.5-cm abdominal aortic aneurysm (AAA) extending to the right common iliac artery also presented with separate aneurysms of both internal iliac arteries. The patient refused conventional surgery, so an endovascular strategy was devised. Initially, the iliac aneurysms were sequentially coil embolized, allowing several weeks to elapse between the embolization sessions to encourage collateral development. A bifurcated Talent endograft was inserted successfully 8 months after the initial intervention; no evidence of endoleaks or mesenteric ischemia has been seen over a 1-year follow-up.

CONCLUSIONS

This case illustrates the feasibility of inducing collateralization prior to endovascular AAA repair that would jeopardize internal iliac artery circulation bilaterally. Sequential embolization of the internal iliac arteries over several months initiates this response, paving the way for eventual endovascular repair of the primary aortic aneurysm.
