An anterior communicating aneurysm (ACA) is a weakened area in an artery at the base of the brain that supplies blood to the frontal lobes. It can cause severe complications, including rupture and bleeding, which can lead to brain damage or death. Symptoms may include sudden onset of severe headache, nausea, vomiting, vision changes, or…
The inferior phrenic artery arises from the abdominal aorta, supplying blood to the diaphragm, along with contributions from the musculophrenic artery. It provides vital nourishment to this crucial muscle, enabling its respiratory and protective functions in separating the thoracic and abdominal cavities. Blood Supply to the Diaphragm: Keeping the Wall Separated Imagine your body as…
Anteroseptal infarct is a heart attack affecting the anterior (front) and septal (dividing) walls of the heart. It occurs due to a blockage in the left anterior descending artery, causing insufficient blood flow and damage to the heart muscle. Despite being a serious event, it often goes unnoticed until a routine EKG reveals characteristic ST-segment…
The femoral artery, a crucial artery in the leg, carries oxygenated blood from the aorta to the thigh and lower leg. It plays a vital role in maintaining blood flow and supplying oxygen and nutrients to the tissues in these regions. A healthy femoral artery ensures proper circulation and functionality of the lower extremities. Arteries…
A left mammary artery graft (LIMA graft) is a surgical procedure used in coronary artery bypass grafting (CABG) to improve blood flow to the heart. The left mammary artery, located beneath the left breast, is harvested and used to create a graft that bypasses a blocked coronary artery. This graft is typically connected to the…
The superior labial artery, a branch of the facial artery, supplies blood to the upper lip. It arises from the facial artery just below the inferior orbital margin and runs down alongside the side of the nose to the upper lip, where it anastomoses with the inferior labial artery. The superior labial artery plays a…
An anterior artery aneurysm is a weakened area in the wall of the anterior cerebral artery, a blood vessel in the brain. It can cause a subarachnoid hemorrhage, a life-threatening condition where blood leaks into the space between the brain and the skull. Symptoms include sudden, severe headache, nausea, vomiting, seizures, and loss of consciousness….
The lateral plantar artery is a branch of the posterior tibial artery that supplies blood to the lateral aspect of the foot. It arises just distal to the origin of the medial plantar artery and courses laterally across the sole of the foot, deep to the plantar aponeurosis. The lateral plantar artery gives off several…
A brain aneurysm size chart is a tool used by healthcare professionals to assess the size of a brain aneurysm, which is a weakened area in the wall of a blood vessel in the brain. The chart helps determine the risk of rupture, which can lead to a life-threatening subarachnoid hemorrhage. Aneurysms are classified based…
A vertebral artery stent is a small, expandable mesh tube inserted into the vertebral artery, a major blood vessel in the neck that supplies blood to the brain. The stent helps to keep the artery open and prevent blockages that can cause stroke. Vertebral artery stents are typically used to treat vertebral artery dissection, stenosis,…
A basilar apex aneurysm is a dilation of the basilar artery at its junction with the posterior cerebral arteries. It is a rare but serious condition that can lead to stroke. Diagnosis is typically made through imaging studies such as CT angiography or MRI. Symptoms may include headache, dizziness, vision problems, and difficulty swallowing. Risk…
The transverse facial artery is a branch of the facial artery that supplies the cheek and buccal musculature. It arises from the facial artery just below the mandible and courses laterally, deep to the facial muscles and superficial to the masseter muscle. The transverse facial artery supplies branches to the parotid gland, masseter muscle, and…
