A vascular anomaly is a localized defect in blood vessels or lymph vessels. These defects are characterized by an increased number of vessels, and vessels that are both enlarged and heavily curved. Some vascular anomalies are congenital, others appear within weeks to years after birth, and others are acquired by trauma or during pregnancy ...
Abnormal development of the lymph vessels results in their failure to connect and drain into the venous system. [9] These lymph vessels can become blocked due to the collection of lymph which forms a cyst as a mass, and are known as lymphatic malformationss. They can be macrocystic, microcystic, or a combination of the two. [9]
A vascular tumor is a vascular anomaly where a tumor forms from cells that make blood or lymph vessels; a soft tissue growth that can be either benign or malignant. [1] Examples of vascular tumors include hemangiomas, hemangioendotheliomas, Kaposi's sarcomas, angiosarcomas, and hemangioblastomas. An angioma refers to any type of benign vascular ...
Lymphohemangioma is a disease characterized by swelling of the lymph nodes and blood vessels.It is variously described as a "mixture of clear fluid and blood-filled cysts", [citation needed] a mass of abnormal swollen veins and lymph nodes, or a tumorous growth of lymph and blood vessels.
An aneurysm is a localized enlargement of arteries, characterized by a balloon-like bulge. [6] It results from the abnormal weakening of blood vessel wall. [7] Common types of aneurysm include abdominal aortic aneurysm, thoracic aortic aneurysm and intracranial aneurysm. [7]
Pulmonary arteriovenous malformations are abnormal communications between the veins and arteries of the pulmonary circulation, leading to a right-to-left blood shunt. [5] [6] They have no symptoms in up to 29% of all cases, [7] however they can give rise to serious complications including hemorrhage, and infection. [5]
There are three distinct types of lymphangioma, each with their own symptoms. They are distinguished by the depth and the size of abnormal lymph vessels, but all involve a malformation of the lymphic system. Lymphangioma circumscriptum can be found on the skin's surface, and the other two types of lymphangiomas occur deeper under the skin.
Arteriosclerosis, literally meaning "hardening of the arteries", is an umbrella term for a vascular disorder characterized by abnormal thickening, hardening, and loss of elasticity [3] of the walls of arteries; [4] this process gradually restricts the blood flow to one's organs and tissues and can lead to severe health risks brought on by atherosclerosis, which is a specific form of ...
