We report a case of extracranial internal carotid artery aneurysm successfully treated with aneurysmal resection and primary end-to-end anastomosis of the proximal and distal internal carotid artery. An 82-year-old woman presented with dysphagia and discomfort of the throat. Magnetic resonance imaging showed a giant aneurysm, and angiography revealed an unruptured partially thrombosed giant aneurysm of 4-cm diameter located in her right extracranial internal carotid artery. Aneurysmal resection and primary end-to-end anastomosis of internal carotid artery were performed. Postoperative computerized tomography angiograms showed that the aneurysm had disappeared and that the patency of the right internal carotid artery was preserved. The postoperative course was uneventful, and her symptoms improved.
We propose that primary end-to-end anastomosis is an ideal method for treating aneurysms because it can maintain antegrade cerebral perfusion and is minimally invasive.
