Vascular myelopathy later in this article. However, TIAs can result from emboli in calcific aortic disease and aortic coarctation. Spinal arteriovenous malformations (AVMs, or angiomatous malformations) are congenital (from birth) abnormalities of blood vessels. Arteries that directly communicate with veins bypass the capillary network (which has not yet developed) and thus creates a shunt. AVMs appear as a mass of convoluted, dilated vessels. In regards to the spinal cord, they are usually located in the thoracolumbar region (between the thoracic and lumbar regions, 60% of the time), as opposed to the upper thoracic (20%) and cervical regions (approximately 15%). Cervical malformations arise
Endometrial arteries body and they enrich the endometrium of the uterus. The joining of endometrial arteries and veins of the endometrium is known as arteriovenous. Endometrial arteries are also involved in the menstrual cycle. When the egg implants onto the endometrium and is not fertilized the endometrial arteries become narrow and the endometrium begins to disintegrate. This is when the endometrium sheds and results in menstruation. Endometrial arteries Arcuate arteries located in the uterus branch out and supply blood to different layers of the uterus. These arteries meet the myometrial-endometrial junction and lead to straight and endometrial arteries. The endometrium receives blood
