Open operative balloon angioplasty of the internal carotid artery: a technique in evolution.
Open operative balloon angioplasty is a treatment alternative for certain nonatherosclerotic lesions of the internal carotid artery (ICA) including fibromuscular dysplasia (FMD). Standard operative exposure of the carotid bifurcation is performed with atraumatic passage of a guidewire and balloon through a carotid bulb arteriotomy. Under direct fluoroscopic guidance, precise dilatation of the involved area is possible with minimal risk of intimal tear/flap or distal embolization as compared with graduated intraluminal dilatation or percutaneous balloon angioplasty. Vascular control of the common and external carotid arteries lessens the risk of embolization resulting from the constant backflow of blood through the ICA before, during, and after balloon angioplasty, adding to the overall safety and efficacy of the procedure. We report a case of asymptomatic critical carotid artery stenosis associated with FMD successfully treated with open operative balloon angioplasty and review the current literature regarding treatment options for FMD of the ICA.
