Aneurysms; Definition, four types, two locations, dilation of an artery due to a weakness in the
arterial wall
Four types of aneurysms
- saccular aneurysms : outpouching of one wall in a circumscribed area
- fusiform aneurysms : involves complete circumference of artery
- dissecting aneurysms : accumulation of blood separating the layers of the arterial wall
- pseudoaneurysm: tear of the full thickness of the arterial wall, leading to a collection of blood contained in the connective tissue
Two locations: abdominal aorta and thoracic aorta
A. location one: abdominal aortic aneurysm
Findings of abdominal aortic aneurysm
- usually asymptomatic
- vague abdominal or back pain
- tenderness on palpation
- hypotension
- diminished pulses in lower extremities
- commonest site: just below renal arteries and above iliac arteries
Treatment – surgical repair
Nursing Interventions
- care of the client undergoing surgery
- after surgery, watch for back pain, a sign of retroperitoneal hemorrhage
- monitor perfusion
- provide comfort measures
- provide emotional support
- teach client – to avoid prolonged sitting and lifting of heavy objects
B. location two: thoracic aortic aneurysm
Findings of thoracic aortic aneurysm
- may be asymptomatic
- vague chest pain
- dyspnea
- distended neck veins
Management – surgical repair
Nursing interventions
- care of the client undergoing surgery
- care of the client undergoing cardiac surgery
Etiology – atherosclerosis
