Aneurysm | #neetpg topic discussion | Dr. Praveen Kr Gupta [DBMCI eGurukul]

Aneurysm is the dilation of a vessel wall without rupture, commonly caused by atherosclerosis or cystic medial necrosis.

Aneurysms can be fusiform or circular, with an external collagen layer preventing complete blood leakage, forming a hematoma.

In tertiary syphilis, there is arbitration of Vasa vasoram leading to vascular ischemia and fibrosis, known as "tree bark vessels."

Mycotic aneurysms are named for their mushroom-like shape, caused by bacterial etiology such as Staph aureus or salmonella gastroenteritis.

Dissection involves a rupture in the internal elastic lamina, commonly seen in hypertension and can be classified as Stanford A (ascending aorta) or Stanford B (descending aorta).

Treatment for ascending aortic involvement is surgical repair, while descending aortic involvement can be managed conservatively with anti-hypertensives.
