External carotid artery-to-petrous internal carotid artery radial artery graft bypass for a giant high cervical aneurysm

Abstract

Abstract Objective To investigate optimal treatment strategies for giant high-cervical internal carotid artery aneurysms. Methods A retrospective analysis was conducted, examining clinical data, surgical approaches, and postoperative outcomes in a case involving a patient with a giant high-cervical internal carotid artery aneurysm. Additionally, pertinent literature was reviewed to contextualize the findings. Results A 52-year-old male patient presented with a one-year history of intermittent coughing, exacerbated by a two-month history of headaches. Digital Subtraction Angiography (DSA) revealed the presence of a giant high-cervical internal carotid artery aneurysm on the right side. The patient underwent an external carotid artery-radial artery-internal carotid artery petrosal segment bypass and aneurysm isolation surgery. Postoperative angiography demonstrated the disappearance of the aneurysm and patency of the bypass. Notably, there were no occurrences of new cerebral ischemia or infarction, no manifestation of new neurological dysfunction, and a marked improvement in the patient's original symptoms. Conclusion The treatment of giant high-cervical internal carotid artery aneurysms necessitates cerebral vascular bypass surgery, with the external carotid artery-radial artery-internal carotid artery petrosal bone segment bypass proving to be an efficacious and preferable therapeutic modality for such lesions.
