Aneurysm II: Clinical Manifestations and Diagnostic Studies

Clinical manifestations of thoracic aortic aneurysm may include dyspnea from pressure on the respiratory system, deep, diffuse chest pain that radiates to the interscapular area, and a brassy, paroxysmal cough.

Aneurysms in the aortic arch and ascending aorta can reduce coronary artery blood flow, leading to angina. Additionally, they may cause respiratory or swallowing difficulties from laryngeal nerve compression.

Compression of the superior vena cava can result in jugular venous distention and facial and arm edema.

An abdominal aortic aneurysm manifests as a pulsatile mass in the periumbilical area, left of the midline, with audible bruits.

Complications of aortic aneurysm include rupture into the retroperitoneal space, causing flank bruising or Grey Turner sign, and rupture into the thoracic or abdominal cavity, leading to hypovolemic shock.

Next, diagnostic studies include chest X-rays to reveal thoracic aorta widening, abdominal X-rays to show aortic wall calcification, and ultrasounds to screen for aneurysm size. CT or MRI scans assess the aneurysm's location.
