Ankle–brachial pressure index types of leg ulcers: Studies in 2006 suggests that an abnormal ABPI may be an independent predictor of mortality, as it reflects the burden of atherosclerosis. It thus has potential for screening for coronary artery disease, although no evidence-based recommendations can be made about screening in low-risk patients because clinical trials are lacking. Ankle–brachial pressure index The ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm (brachium). Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral
Sphenopalatine artery Sphenopalatine artery The sphenopalatine artery (nasopalatine artery) is an artery of the head, commonly known as the artery of epistaxis. The sphenopalatine artery is a branch of the maxillary artery which passes through the sphenopalatine foramen into the cavity of the nose, at the back part of the superior meatus. Here it gives off its posterior lateral nasal branches. Crossing the under surface of the sphenoid, the sphenopalatine artery ends on the nasal septum as the posterior septal branches. Here it will anastomose with the branches of the greater palatine artery. The sphenopalatine artery is the artery responsible for the
