Gastric antral vascular ectasia, dilation of small blood vessels in the last part of the stomach. Telangiectasias are small dilated blood vessels found anywhere on the body, but commonly seen on the face around the nose, cheeks, and chin. Venous ectasia, dilation of veins or venules, such as: Chronic venous insufficiency, often in the leg
Vascular resistance is the amount of force circulating blood must overcome in order to allow perfusion of body tissues. Narrow vessels create more vascular resistance, while dilated vessels decrease vascular resistance. Vasodilation acts to increase cardiac output by decreasing afterload, −one of the four determinants of cardiac output. [4]
AGE is the second most common cause of death while diving (drowning being the most common stated cause of death). Gas bubbles within the arterial circulation can block the supply of blood to any part of the body, including the brain, and can therefore manifest a vast variety of symptoms.
Lymphangiectasia, also known as "lymphangiectasis", [1] is a pathologic dilation of lymph vessels. [2] When it occurs in the intestines it is known as intestinal lymphangiectasia, colloquially recognized as Waldmann's disease in cases where there is no secondary cause. [3]
There are generally three aortic sinuses, one anterior and two posterior sinuses. These give rise to coronary arteries: [4] [better source needed] The left aortic or left posterior aortic sinus gives rise to the left coronary artery; The right aortic or anterior aortic sinus gives rise to the right coronary artery;
The ptosis of Horner syndrome can be quite mild or barely noticeable (partial ptosis). [7] When anisocoria occurs and the examiner is unsure whether the abnormal pupil is the constricted or dilated one, if a one-sided ptosis is present then the abnormally sized pupil can be presumed to be on the side of the ptosis.

Since one side of the body sweats and flushes appropriately to the condition, the other side of the body will have an absence of such symptoms. [ 3 ] Harlequin syndrome can alternatively be the outcome of a one-sided endoscopic thoracic sympathectomy (ETS) or endoscopic sympathetic blockade (ESB) surgery.
A second specialist ultrasound exam remains preferable to a CT scan. [ citation needed ] As a wide range of pelvic and abdominal pathology can cause symptoms consistent with those symptoms due to left ovarian vein reflux, prior to embolisation of the left ovarian vein, a careful search for such diagnoses is essential.
