Abstract:
Objective To summarize the important role of guiding road in treatment of carotid artery lesion by covered stent.Methods From January 2013 to October 2014,the consecutive data were collected from 10 patients with carotid artery lesions treated with covered stents,including 8 of aneurysms,one of traumatic pseudoaneurysm and one of recurrent carotid cavemous fistula.For 5 lesions with straight carotid artery path,the use of conventional 6F Envoy guiding catheter path was established,or the introduce sheath itself was used as guiding catheter;for 4 lesions with tortuous carotid artery path,Neuron070 guiding catheters and 70 cm 7-French reinforced long introduce sheath was used to establish guiding road;for one ophthalmic artery lesion with tortuous carotid artery path,conventional 6F Envoy guiding catheter was used to establish guiding road.The established guiding roads were followed by navigation of covered stent.Hunt-Hess scale was performed to evaluate the neurological functions before operation,immediate post-operation and one week after surgery.Results Except for the guiding road for one of ophthalmic artery aneurysm with tortuous carotid artery path,the remaining covered stents in the 9 patients successfully reached the lesions.All covered stents were successfully deployed in the patent arteries across the lesions,the lesions were cured immediately without contrast agent filling;the cure rate reached 90％.Hunt-Hess scale score was 0 in 9 patients before operation,immediate post-operation and one week after surgery;that was one in one subarachnoid hemorrhage patient.Conclusions A good guiding road is the key to reach the carotid artery lesion for covered stent.Usage of Neuron070 guiding catheter and reinforced long introduce sheaths can significantly extend the scope of application of the covered stent in tortuous carotid artery lesions.
