Aneurysm II: Clinical Manifestations and Diagnostic Studies01:21

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Aneurysm I: Introduction

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Summary

Extracranial carotid artery aneurysms are rare but serious, often caused by atherosclerosis. Surgical repair with aneurysmectomy and arterial reconstruction is necessary, yielding good long-term results with low stroke incidence.

Area of Science:

  • Vascular Surgery
  • Cerebrovascular Diseases
  • Aneurysm Treatment

Background:

  • Extracranial carotid artery aneurysms are uncommon vascular lesions.
  • These aneurysms can lead to significant neurological complications.
  • Atherosclerosis is the leading cause, followed by trauma and prior surgery.

Purpose of the Study:

  • To present the treatment outcomes of extracranial carotid artery aneurysms.
  • To analyze the etiology, location, and surgical repair methods.
  • To evaluate the incidence of neurological sequelae and long-term patency.

Main Methods:

  • Retrospective multicentric study of 91 extracranial carotid artery aneurysms in 76 patients.
  • Surgical interventions included aneurysmectomy with various reconstruction techniques (anastomosis, vein graft, Dacron graft, ligature).
  • Patient follow-up ranged from 2 months to 12 years.

Main Results:

  • Atherosclerosis accounted for 80.2% of cases; 67% involved the internal carotid artery.
  • Symptomatic presentations included transient ischemic attack (36.3%) and stroke (12.1%).
  • Postoperative stroke occurred in 5.5% of patients; long-term follow-up showed no new neurological events and patent reconstructions.

Conclusions:

  • Extracranial carotid artery aneurysms require diverse surgical approaches based on individual characteristics.
  • Aneurysmectomy with arterial reconstruction is crucial for successful repair.
  • The study demonstrates favorable long-term outcomes with low recurrence and morbidity.
