A pulmonary embolism is a blockage of an artery in the lungs. The embolism prevents blood and nourishment from getting to a specific area of the lungs. This may lead to the death of lung tissue in this area. Damage to the lungs may make it difficult for the lungs to work properly. In severe cases, a pulmonary embolism can lead to death.

The mesenteric arteries supply blood to the large and small intestines. Mesenteric ischemia occurs when the blood cannot flow through one or more of these arteries as well as it should due to narrowing or blockage, and the intestines don’t receive the necessary oxygen to perform normally.

Renovascular disease affects the blood vessels of your kidneys, called the renal arteries and veins. When your kidney blood vessels narrow (stenosis) or have a clot (thrombosis), your kidney is less able to function properly.

Peripheral artery disease (PAD) is disease of any blood vessel that is not part of the heart or brain. PAD is caused by fatty deposits that can build up in the walls of the arteries (atherosclerosis) and is a common circulatory problem in which narrowed arteries reduce blood flow to the limbs, usually the legs. Conditions related to PAD include: acute limb ischemia; claudication; gangrene / limb salvage; and ulcerative disease.

Carotid artery disease occurs when the major arteries in the neck become narrowed or blocked. These arteries supply blood from the heart to the brain. Carotid artery disease is a serious health problem because it can cause a stroke. Cartoid artery disease can be asymptomatic or symptomatic.

Visceral artery aneurysms are aneurysms in the abdominal cavity, including the celiac artery, the superior mesenteric artery, the inferior mesenteric artery, the hepatic artery, the splenic artery and the renal arteries. These arteries can weaken, which can lead to an expansion or bulging called an aneurysm.

The part of your aorta that runs through your chest is called the thoracic aorta, and when a weak area of the thoracic aorta expands or bulges, it is called a thoracic aortic aneurysm (TAA). Approximately 25 percent of aortic aneurysms occur in the chest.

The aorta is the largest artery that supplies oxygen-rich blood to the body and it runs from the heart through the center of the chest and abdomen. When a weak area of the abdominal aorta expands or bulges, much like a balloon, it is called an abdominal aortic aneurysm (AAA).
