Symptoms of AVMs vary according to their location. Most neurological AVMs produce few to no symptoms.Often the malformation is discovered as part of an autopsy or during treatment of an unrelated disorder (an "incidental finding"); in rare cases, its expansion or a micro-bleed from an AVM in the brain can cause epilepsy, neurological deficit, or pain.
A cerebral AVM causes blood to be shunted directly from arteries to veins because the capillary bed is lacking, causing a disrupted circulation. [10] [11] The overall annual incidence of haemorrhage from a ruptured AVM is 2-4%. Smaller AVMs have a greater propensity for haemorrhaging, whereas larger AVMs tend to more often cause seizures ...

In medicine (gastroenterology), angiodysplasia is a small vascular malformation of the gut. It is a common cause of otherwise unexplained gastrointestinal bleeding and anemia. Lesions are often multiple, and frequently involve the cecum or ascending colon, although they can occur at other places.
Verapamil, nimodipine, and other calcium channel blockers may help reduce the intensity and frequency of the headaches. [1] A clinician may recommend rest and the avoidance of activities or vasoactive drugs which trigger symptoms (see § Causes). [1] Analgesics and anticonvulsants can help manage pain and seizures, respectively. [1]

This is most commonly in the lower back area in the region of the conus medullaris or cauda equina. Therefore, spina bifida affects the bowel similarly to a lower motor neuron spinal cord injury, resulting in a flaccid, unreactive rectal wall. The anal sphincter does not contract and close, leading to stool leakage. [12]
The treatment of intestinal ischemia depends on the cause and can be medical or surgical. However, if bowel has become necrotic, the only treatment is surgical removal of the dead segments of bowel. [34] In non-occlusive disease, where there is no blockage of the arteries supplying the bowel, the treatment is medical rather than surgical ...
