By Ed Susman CHICAGO, IL -- December 4, 2006 -- Large and giant life-threatening aneurysms of the internal carotid artery can be successfully excluded by sealing the parent artery with either metal coils, researchers reported here at the 92nd scientific assembly and annual meeting of the Radiological Society of North America (RSNA). In their study, there were no deaths and no long-term morbidity in performing the minimally-invasive endovascular occlusion of the parent artery, said researcher Frédéric Clarençon, MD, a resident in the department of neuroradiology at Hôpital Pitié Salpétrière, Paris, France. "More than 90% of the aneurysms were excluded. About 9% of the time, the parent vessel will recanalize which justifies long-term angiographic follow-up," Dr. Clarençon said in his oral presentation on November 30th. "The occlusion of the parent artery for treatment of the giant/large aneurysms of the internal carotid artery is still a valid, safe and effective technique with good angiographic results and good clinical tolerance to the vessel occlusion on long-term follow-up," he said. Dr. Clarençon reviewed data on the treatment of patients who presented to his hospital with large internal carotid artery aneurysms, defined as greater than 15 mm in diameter, or giant internal carotid artery aneurysms, defined as lesions 25 mm in diameter. Between 1996 and November 2006, 12 men and 8 women with a mean age of 45 years (range 23 to 68 years), underwent a cerebral magnetic resonance imaging (MRI) and an angiomagnetic resonance test. Patients may also have been diagnosed using a computed tomography (CT) scan and angio-CT before treatment. Occlusion of parent artery was performed usually using coils, Dr. Clarençon said. In 2 cases glue was also used to occlude the parent artery in 2 cases. In all cases, Dr. Clarençon was able to review at least 5 years of follow-up with either CT or MRI. In 19 of the 20 cases, the aneurysm remained sealed over the course of follow-up. A second embolization was required for 1 patient. Shrinkage of the aneurismal thrombosed compartment was seen on all control imaging scans.
