An arteriovenous malformation (AVM) is an abnormal connection between arteries and veins, bypassing the capillary system. Usually congenital , this vascular anomaly is widely known because of its occurrence in the central nervous system (usually as a cerebral AVM ), but can appear anywhere in the body.
A common method of grading cerebral AVMs is the Spetzler-Martin (SM) grade. [14] This system was designed to assess the patient's risk of neurological deficit after open surgical resection (surgical morbidity), based on characteristics of the AVM itself. Based on this system, AVMs may be classified as grades 1–5.
Although the lesions can be notoriously hard to find, the patient usually is diagnosed by endoscopy. A new technique, pill enteroscopy, has been a major advance in diagnosis, especially in the small bowel which is difficult to reach with traditional endoscopy. With this technique a pill that contains a video camera and radio transmitter is ...
An endoclip is a metallic mechanical device used in endoscopy in order to close two mucosal surfaces without the need for surgery and suturing. Its function is similar to a suture in gross surgical applications, as it is used to join together two disjointed surfaces, but, can be applied through the channel of an endoscope under direct visualization

The device is able to give a more normal life to people with abnormal heart rhythms and a risk of sudden cardiac arrest, said Dr. Ali Sheikh, a cardiac electrophysiologist who helped install the ...
Therapeutic endoscopy is the medical term for an endoscopic procedure during which treatment is carried out via the endoscope. This contrasts with diagnostic endoscopy , where the aim of the procedure is purely to visualize a part of the gastrointestinal , respiratory or urinary tract in order to aid diagnosis .
Gastric antral vascular ectasia (GAVE) is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia. [1] [2] The condition is associated with dilated small blood vessels in the gastric antrum, which is a distal part of the stomach. [1]
