Extracranial Internal Carotid Artery Aneurysm in a Patient with Marfan Syndrome

Surgical management of extracranial internal carotid artery aneurysm-Case report and literature review

Key Clinical Message

Extracranial internal carotid artery aneurysms (EICAAs) can lead to serious medical conditions, such as stroke or compression over cranial nerves. In very few cases, there may be hemorrhagic complications due to the rupture. Although rare, they should be suspected cause in every patient with transitory ischemic attack or stroke, especially in the presence of pain, palpable mass or bruit in the neck.

Abstract

Extracranial internal carotid artery aneurysms (EICAAs) are rare arterial aneurysms, with a prevalence of less than 1%. Although they are not common, these aneurysms can lead to serious medical conditions, such as stroke or compression over cranial nerves. In very few cases, there may be hemorrhagic complications due to the rupture of the aneurysm. This report presents a case of a successful surgical intervention for EICAA, and an overview of symptoms, risk factors, causes, diagnostic procedures, treatments, and potential postoperative complications. A 70-year-old Albanian lady had been experiencing pain due to a pulsating mass in her neck for many years. Physical examination did not reveal any signs of infection, injury, or previous surgery. A palpable thrill and a carotid bruit were detected over an evident pulsating mass on the left side of her neck. Her past medical history was consistent with three transitory ischemic attacks in recent months and a stroke 5 years earlier. Comorbidities included hypercholesterolemia, hypertension, and long-standing coronary artery disease. Imaging investigation in terms of ultrasound and CT-scan confirmed the presence of an aneurysm of the proximal tract of the internal carotid artery measuring 42 × 31 mm. Surgery was indicated on symptomatic and anatomical grounds. The procedure was carried out under general anesthesia. After proximal and distal clamping, the aneurysm was excised followed by end-to-end anastomosis of the internal carotid artery. The postoperative course was uneventful, and the patient was discharged home on the fifth postoperative day. Despite the growing number of reported cases of successful endovascular treatment for internal carotid artery aneurysms, open surgery remains a safe and effective treatment option. However, it is crucial to provide customized treatment plans for each patient based on their individual characteristics and the particularities of their aneurysm.

Extra-Thoracic Aneurysms in Marfan Syndrome: A Systematic Review of the Literature

INTRODUCTION

Marfan syndrome (MS) most often shows as thoracic aortic aneurysm (TAA) or aortic dissection, but it may also involve other vascular territories.

OBJECTIVE

To identify those extra-thoracic vascular manifestations most frequently associated with MS.

METHODOLOGY

Systematic review of the literature with PRISMA criteria. The following databases were included: Medline, Embase, Web of Science (WOS), Cumulative Index of Nursing and Health Sciences Literature (CINHAL); Spanish database MEDESY Cochrane Central Register of Controlled Trials (CENTRAL).

RESULTS

10,008 articles were identified, leaving 155 for the first stage of data analysis (total incidence of aneurysms) and 83 for the second (descriptive data analysis). Overall, 518 aneurysms were identified: 149 in the head and neck, 94 in the extremities 275 in the aortic, iliac and visceral sectors. Mostly, they were simultaneously discovered during studies of the AAT. In the abdominal aorta, the presentation with rupture in 11 of 32 patients stands out. Resection and bypass was the most frequently used method for repair in the treated cases.

CONCLUSIONS

Although its frequency in the general population is unknown, this systematic review suggests that extra-thoracic aneurysmal arterial involvement in the MS may be more frequent than expected. We believe screening for aneurysms in other vascular sectors may be advisable, especially in patients with MS and AAT.

Giant internal carotid artery aneurysms and porcelain aorta in an elderly patient with Marfan syndrome

Marfan syndrome (MFS) an inherited disorder caused by FBN1 gene variants, is well known to cause lethal aortic aneurysm and dissections at a relatively young age. Here, we report giant internal carotid artery aneurysms (ICAAs) and porcelain aorta in an elderly patient with MFS.

Clinical Analysis of Interventional Therapy for Eight Cases of Extracranial ICA Aneurysm

Objective:

To explore the interventional therapy and clinical efficacy of extracranial ICA aneurysm.

Methods:

The clinical data of eight patients with extracranial ICA aneurysm treated by interventional stent implantation from December 2014 to February 2018 in the Neurosurgery Department of the Third Hospital of Mianyang were analyzed. And this research was a retrospective analysis. All patients underwent digital subtraction angiography (DSA) and were diagnosed with extracranial carotid artery aneurysm. These patients, therefore, were treated with interventional stent implantation.

Results:

Interventional treatment was successfully conducted on all eight patients. In eight patients, the aneurysm cavity was not developed immediately after angiography, and in one case, the aneurysm cavity was developed with coil-assisted embolization. All the internal carotid arteries were well developed, with no complications such as intraoperative rupture, bleeding and thrombosis occur. Follow-up for three months to two years showed that the patients recovered well, the GOS score was 4 points for patients with cerebral infarction, and the rest reached five points. Follow-up CTA showed no signs of aneurysm recurrence or ICA restenosis.

Conclusion:

Interventional stent placement is a preferable and relatively safe method for the treatment of extracranial carotid artery aneurysm with less trauma and short operation time.

Beyond plaque: A pictorial review of non-atherosclerotic abnormalities of extracranial carotid arteries

The common carotid artery (CCA) and extracranial internal carotid artery are subject to a wide variety of non-atheromatous pathologies. These entities are often overshadowed in both research and clinical realms by atherosclerotic disease. Nevertheless, non-atherosclerotic disease of the carotid arteries may have profound, even devastating, neurologic consequences. Hence, this review will cover both common and uncommon forms of extracranial carotid artery pathologies in a pictorial format, in order to aid the diagnostician in identifying and differentiating such pathologies.
