Endovascular stenting for pseudoaneurysms of the cervical carotid artery.
The authors report two cases of pseudoaneurysm of the cervical carotid artery treated with endovascular stenting. One patient presented with cerebral ischemia due to traumatic carotid dissection and underwent stent placement 3 weeks after injury when the wide-necked pseudo aneurysm was seen to enlarge at the dissecting portion. The aneurysm thrombosed while the carotid artery remained patent without ischemic complications for 2 years. The other patient developed repeated massive bleeding from an exposed pseudoaneurysm at the right carotid-subclavian junction resulting from radiotherapy for thyroid cancer with subsequent skin infection. Since skin grafting failed and two attempts at coil embolization resulted in compaction with recurrent enlargement of the aneurysm, endovascular stenting was performed with endosaccular coil packing between the stent struts. Hemostasis was achieved for 2 months. Both cases illustrate successes of the stent in highly difficult situations.
