Angioplasty of the Superior Gluteal Artery in 34 Patients With Buttock Claudication

Endovascular Treatment of Claudication due to Isolated Internal Iliac Artery Occlusive Disease

Aortoiliac occlusive disease is a common cause of lower extremity claudication. Patients are typically found to have diminished femoral pulses and abnormal noninvasive vascular studies of the lower extremities. Isolated lesions of the internal iliac arteries are much less commonly treated but can cause similar claudication symptoms in the buttocks, hips, or thighs. Occlusive disease in the internal iliac artery is more challenging to diagnose because the lower extremity pulses and vascular studies can be normal. This may falsely steer the diagnosis away from a vascular etiology. We present a case of disabling buttock claudication in a patient with normal pulses and isolated ipsilateral internal iliac artery stenosis. This was treated successfully with drug-eluting balloon angioplasty. We review the literature for similar cases of isolated internal iliac artery occlusive disease and summarize the disease characteristics and treatment modalities.

Internal Iliac Artery Stenosis: Diagnosis and How to Manage it in 2015

Lower extremity arterial disease (LEAD) is a highly prevalent disease affecting 202 million people worldwide. Internal iliac artery stenosis (IIAS) is one of the localization of LEAD. This diagnosis is often neglected when a patient has a proximal walking pain since most physicians evoke a pseudoclaudication. Surprisingly, IIAS management is reported neither in the Trans-Atlantic Inter-Society Consensus II nor in the report of the American College Foundation/American Heart Association guidelines. The aims of this review are to present the current knowledge about the disease, how should it be managed in 2015 and what are the future research trends.
