- Try building your search one term at a time, and be as specific as you can! Search term example: "chronic cough".
- Do not enter multiple findings such as "anemia, chronic cough, weight loss, vomiting" all at the same time.
- After selecting your term from the search results a list of possible diagnoses will be generated. If the list is too long, you will be able to narrow it down by entering additional terms.
- Do not enter values such as "heart rhythm 110" or "sodium 125", instead use "tachycardia" or "hyponatremia".

- Definition
-
Abnormal, tangled collections of dilated blood vessels that result from congenitally malformed vascular structures in which arterial afferents flow directly into venous efferents without the usual resistance of an intervening capillary bed; A common type is the congenital arteriovenous fistula (ARTERIOVENOUS FISTULA /congenital); For arteriovenous malformations in the brain, INTRACRANIAL ARTERIOVENOUS MALFORMATIONS is available; (From Merck Manual, 15th ed)----------------------------------------------Arteriovenous Malformation; AVM; Arteriovenous Malformation of the Brain; Spinal Arteriovenous Malformation; Arteriovenous malformation (AVM) is a congenital defect in which arteries and veins are tangled and not connected by capillaries; The lack of capillaries allows blood traveling through the abnormal vessels to flow rapidly and under high pressure and prevents the nutrient rich blood in the arteries from reaching the tissues; AVM can occur in many different parts of the body, but those located in the brain, brainstem and spinal cord (neurological AVM) can affect the entire body-----[NORD 2005]-------------
