TREATMENT OF DISSECTING PSEUDOANEURYSM OF THE CERVICAL INTERNAL CAROTID-ARTERY USING A WALL STENT AND DETACHABLE COILS - CASE-REPORT

OBJECTIVE AND IMPORTANCE: This case illustrates the use of an endovasc ular stent and coiling combination to treat a giant wide-necked pseudo aneurysm of the cervical internal carotid artery. CLINICAL PRESENTATIO N: A 20-year-old male patient presented with a bilateral dissection of the cervical internal carotid artery and a right giant wide-necked ps eudoaneurysm of the cervical segment of the internal carotid artery af ter a high-speed motor vehicle collision. INTERVENTION: After failing conservative therapy, the patient was treated by endovascular placemen t of a Palmaz wall stent at the level of the pseudoaneurysm and fillin g of the pseudoaneurysm with multiple Guglielmi detachable coils. Obli teration of the pseudoaneurysm was achieved, and patency of the right internal carotid artery was maintained. CONCLUSION: The patient's neur ological symptoms resolved completely after treatment, and he sustaine d no neurological complications during the 20-month follow-up period. This case illustrates the successful treatment of a wide-based giant p seudoaneurysm by using a combination of an endovascular stent and coil embolization.
