Peripheral artery disease peripheral artery disease: If peripheral artery disease is suspected, the initial study is the ankle–brachial index (ABI). The ABI is a simple, non-invasive test, which measures the ratio of systolic blood pressure in the ankle to the systolic blood pressure in the upper arm. This is based on the idea that if blood pressure readings in the ankle are lower than those in the arm, a blockage in the arteries that provide blood from the heart to the ankle is suspected. An ABI range of 0.90 to 1.40 is considered normal. A person is considered to have PAD when the
Artery of the pterygoid canal small branch which anastomoses with the other tympanic arteries. It can end in the oropharynx. In this case; the artery passes backward along the pterygoid canal with the corresponding nerve. It The artery is a small, inconstant branch which passes into the pterygoid canal and anastomoses with a pterygopalatine branch of the maxillary artery. Artery of the pterygoid canal The artery of the pterygoid canal (Vidian artery) is an artery in the pterygoid canal, in the head. It usually arises from the external carotid artery, but can arise from either the internal or external carotid artery or serve as an
