HAEMANGIECTASIA Meaning and
Definition
-
Haemangiectasia is a medical term that refers to a pathological condition characterized by the dilation or enlargement of blood vessels, particularly the capillaries. The term is derived from 'haemangi' (meaning blood vessels) and 'ectasia' (meaning dilation or enlargement).
In haemangiectasia, the walls of the blood vessels become weak and lose their elasticity, resulting in abnormal and persistent enlargement. This condition commonly affects the smallest blood vessels, known as capillaries, although it can also involve larger vessels.
The exact cause of haemangiectasia is not well understood, but it is often associated with underlying medical conditions that weaken or damage blood vessels. These conditions can include long-term hypertension, atherosclerosis (the deposition of fatty plaques in arteries), or connective tissue disorders such as Marfan syndrome or Ehlers-Danlos syndrome.
The clinical presentation of haemangiectasia can vary depending on the affected blood vessels' location and size. Symptoms may include visible red or purple dilated blood vessels, known as telangiectasias, skin discoloration, ulcers, or bleeding. Depending on the severity and location of the condition, complications such as tissue necrosis or chronic wounds might arise.
Diagnosis of haemangiectasia typically involves a physical examination, medical history evaluation, and possibly imaging studies like ultrasound or angiography to assess the extent of blood vessel involvement.
Treatment options for haemangiectasia may vary based on individual cases, but may include medication to control underlying medical conditions, topical treatments to manage symptoms or promote healing, or in some cases, surgical interventions to repair or remove damaged blood vessels.

Etymology of HAEMANGIECTASIA
The word "haemangiectasia" is derived from two root terms: "haema" and "angiectasia".
1. "Haema" (or "hema") is derived from the Greek word "haima", which means "blood". In medical terminology, it is commonly used to refer to blood-related conditions or structures.
2. "Angiectasia" is derived from the Greek term "angiektasis", which combines "angiei", meaning "vessel", and "ektesis", meaning "expansion" or "dilation". In medical terminology, "angiectasia" is used to describe an abnormal or pathological dilation of blood vessels.
Therefore, "haemangiectasia" refers to an abnormal or pathological dilation of blood vessels.
