Capillary aneurysms
Capillary Aneurysms
Capillary aneurysms (pronunciation: /kæpɪlɛri æn.jʊr.ɪzm/) are small, localized dilations or outpouchings of capillaries, the smallest and most numerous of the blood vessels in the body.
Etymology
The term "capillary aneurysm" is derived from the Latin capillaris meaning "hair-like" and the Greek aneurysma meaning "dilation".
Definition
A capillary aneurysm is a small, balloon-like swelling in the wall of a capillary. This can occur when the wall of the capillary becomes weakened, often due to damage or disease.
Causes
Capillary aneurysms can be caused by a variety of factors, including genetic disorders, inflammation, infection, and trauma. Certain medical conditions, such as hypertension and atherosclerosis, can also increase the risk of developing capillary aneurysms.
Symptoms
Capillary aneurysms often do not cause any symptoms and may go unnoticed until they rupture, leading to bleeding or hemorrhage. When symptoms do occur, they can include pain, swelling, and changes in skin color.
Diagnosis
Diagnosis of capillary aneurysms typically involves imaging tests, such as ultrasound, CT scan, or MRI. These tests can help to visualize the aneurysm and determine its size and location.
Treatment
Treatment for capillary aneurysms depends on the size and location of the aneurysm, as well as the patient's overall health. Options may include observation, medication, or surgery.
