Blue rubber bleb nevus syndrome is a rare disorder that consists mainly of abnormal blood vessels affecting the skin or internal organs – usually the gastrointestinal tract. [1] The disease is characterized by the presence of fluid-filled blisters ( blebs ) as visible, circumscribed, chronic lesions ( nevi ).
The esophageal veins drain blood from the esophagus to the azygos vein, in the thorax, and to the inferior thyroid vein in the neck. It also drains, although with less significance, to the hemiazygos vein, posterior intercostal vein and bronchial veins. [citation needed]
Esophageal varices seven days after banding, showing ulceration at the site of banding. The upper two thirds of the esophagus are drained via the esophageal veins, which carry deoxygenated blood from the esophagus to the azygos vein, which in turn drains directly into the superior vena cava. These veins have no part in the development of ...
In such treatments, functional blebs facilitate the circulation of aqueous humor, the blockage of which will lead to increase in eye pressure. Use of collagen matrix wound modulation device such as ologen during glaucoma surgery is known to produce vascular and functional blebs, which are positively correlated with treatment success rate.
Depending on the amount of the blood loss, symptoms may include shock. Upper gastrointestinal bleeding can be caused by peptic ulcers, gastric erosions, esophageal varices, and rarer causes such as gastric cancer. The initial assessment includes measurement of the blood pressure and heart rate, as well as blood tests to determine the hemoglobin.
A venous lake (also known as phlebectasis [1]) is a generally solitary, soft, compressible, dark blue to violaceous, 0.2- to 1-cm papule commonly found on sun-exposed surfaces of the vermilion border of the lip, face and ears. [2] [3] [4] Lesions generally occur among the elderly. [5] [6]
To ensure complete separation of the azygous vein system from the intramucosal venous plexus, an end-to-end anastomosing stapling device transects and anastomosis a region of the esophagus 4–6 cm above the gastroesophageal junction. This anastomosis can then be reinforced with vicryl suture.
Esophageal diseases can derive from congenital conditions, or they can be acquired later in life. Many people experience a burning sensation in their chest occasionally, caused by stomach acids refluxing into the esophagus , normally called heartburn.
