Bilateral Cavernous Carotid Aneurysms: The Growth Potential of a Contralateral Aneurysm after Therapeutic Unilateral Internal Carotid Artery Occlusion

Atypical Symptomatic Bilateral Spontaneous Cavernous Carotid Aneurysm with Systemic Vessel Wall Pathology in Young Female: A Rare Case Report

Bilateral cavernous carotid aneurysm (CCA) is a rare entity. Its association with connective tissue disorder makes the diagnosis and treatment of symptomatic patient an enigma. We present a case report of a 25-year-old female medical student presented to us with bilateral spontaneous atypically symptomatic CCA with incidentally diagnosed case of Ehlers–Danlos syndrome. Both surgical and endovascular options of treatment were weighed and were ultimately treated satisfactorily by high-flow bypass with carotid artery ligation with an insurance bypass.

Bilateral cavernous carotid aneurysms treated by two-stage extracranial-intracranial bypass followed by parent artery occlusion: case report and literature review

Bilateral cavernous carotid aneurysms (CCAs) are often not amenable to neurosurgical clipping or endovascular coiling. Here, we report the case of a 50-year-old female who presented with a 1-year history of gradual severe headache. Preoperative angiograms revealed bilateral CCAs. Among these findings, the right giant CCA had been trapped after the external carotid artery-saphenous vein-middle cerebral artery (ECA-SV-MCA) bypass 8 years prior. Additionally, the left CCA was again trapped after the internal maxillary artery-radial artery-middle cerebral artery (IMA-RA-MCA) bypass, followed by parent artery occlusion (PAO), because of the enlargement of a 0.4-cm aneurysm to a 1.3-cm aneurysm during the 5th to 8th years following surgery. Postoperative radiologic findings proved that the aneurysms disappeared with good graft patency of the bilateral anastomoses and excellent filling of the bilateral MCA territories. This is the first case of bilateral CCAs treated with two stages of bilateral high-flow extracranial-intracranial (EC-IC) bypass, including an IMA-RA-MCA bypass.
