Carotid stenting dilation and cerebral angiography. Carotid stenting is the preferred therapy for patients who are at an increased risk with carotid surgery. High risk factors include medical comorbidities (severe heart disease, heart failure, severe lung disease, age > 75/80, etc.) and anatomic features (contralateral carotid occlusion, radiation therapy to the neck, prior ipsilateral carotid artery surgery, intra-thoracic or intracranial carotid disease) that make surgery difficult or risky. Anatomic high surgical risk: Co-morbid high surgical risk: Using the criteria of successful trials, candidates are either symptomatic (TIA or stroke) patients with >50% stenosis of the carotid artery, or are asymptomatic with >80%
Endometrial arteries the baby. The uterus, part of the female reproductive system, is composed of the myometrium and the endometrium. The myometrium is made of smooth tissue and the endometrium lines the uterus. The endometrium is important in pregnancy because it is involved in the development of the placenta and it is where the fertilized egg implants itself during pregnancy. In the endometrium there are endometrial arteries which are also known as spiral arteries. The arcuate arteries located in the myometrium, branch out into the myometrium and then spread throughout endometrium forming endometrial arteries which is how the endometrium obtains blood.
