Petrous Internal Carotid Artery Aneurysm: A Systematic Review

et al. 2020

Object: Petrous internal carotid aneurysm (PA) concomitant with a mass lesion and cranial nerve palsy is relatively rare. In recent years, flow-diverter stent implantation is being widely used as an alternative treatment for PA. However, alternative treatments are not available for all patients for various reasons, including the tortuosity of the parent carotid artery, allergies to contrast material, or high cost. It is, therefore, important to compare the relative outcomes of different treatment methods. Here, we have accordingly reviewed the available literature on the treatments for PA. Methods: We searched PubMed, MEDLINE, and other databases, such as OvidSP using the terms "aneurysm ", "carotid artery", and "petrous " and identified 221 articles. We also performed a literature review and discussed and compared the etiologies, symptoms, treatment methods, and clinical outcomes in patients with PA. Results and Conclusions: The systematic review revealed that the onset of secondary aneurysms was generally manifested by bleeding (p<0.001), while the onset of primary aneurysms was manifested by cranial nerve deficits (p= 0.0014); the prognosis after treatment of 34 cranial nerve palsies in 25 cases was reported.

“…Nevertheless, they can produce a wide range of clinical signs and symptoms, depending on the aneurysm's size, direction of growth, and location within the carotid canal. Typically, patients present with symptoms in the third de- cade of life; 29,52 these commonly include headaches, 10,27,52,66 diplopia, 27 Horner syndrome, 10,25,52 facial numbness, 23,42 facial palsy, 27,42 pulsatile tinnitus, 27,53,66 dizziness, 42 or hearing loss. 10,25,27,42,43,53 Symptoms arise as a result of hemorrhage into or mass effect on neighboring structures of the carotid canal.…”

“…21 Early attempts at surgery were associated with high rates of mortality. 27 Cerebral revascularization with a high-flow interpositional bypass is a feasible strategy in patients with complex aneurysms that cannot be directly clipped and who do not tolerate ICA occlusion, as demonstrated with a balloon occlusion test. 10,39,53 As mentioned earlier, the balloon occlusion test produces false-negative results in predicting which patients will experience complications related to a surgical ICA occlusion.…”

“…36,66 Histological examination demonstrates degeneration of the internal elastic lamina and medial aplasia as seen in intracranial berry aneurysms. 27,31 The management of these lesions remains challenging, particularly in those that present incidentally in asymptomatic patients. Current treatment options include close observation, proximal occlusion or trapping with endovascular balloon occlusion, coil embolization, stent placement with or without coil embolization, and surgical trapping followed by revascularization through a high-flow bypass.…”

Aneurysms arising in the petrous segment of the internal carotid artery (ICA) are rare. Although the causes of petrous ICA aneurysms remain unclear, traumatic, infectious, and congenital origins have been implicated in their development. These lesions can be detected incidentally on routine neuroimaging. Patients can also present with a wide spectrum of signs and symptoms, including cranial nerve palsies, Horner syndrome, pulsatile tinnitus, epistaxis, and otorrhagia. The treatment of petrous ICA aneurysms remains challenging. Treatment options include close observation, endovascular therapies, and surgical trapping with or without revascularization. Management dilemmas exist, particularly for incidental lesions found in asymptomatic patients. The authors review the literature and discuss the anatomy of the petrous ICA as well as the pathophysiological features of aneurysms arising in this region, and they propose a management paradigm with current treatment options.
