Aneurysms Of The Side Branches Of The Aorta

Aneurysms can occur at any major side branch of the aorta; these aneurysms are far less frequent than AAA or TAA.

Risk factors include atherosclerosis, hypertension, cigarette smoking and older age. A localized infection can cause mycotic aneurysms.

Aneurysms can occur at any major side branch of the aorta; these aneurysms are far less frequent than AAA or TAA. Risk factors include atherosclerosis, hypertension, cigarette smoking and older age. A localized infection can cause mycotic aneurysms. The subclavian artery aneurysms are sometimes associated with cervical ribs or thoracic outlet syndrome. Aneurysms A. splanchnica are rare. About 60% occur in the splenic artery, 20% in the hepatic artery and 5.5% in the superior mesenteric artery. Aneurysms of the splenic artery are more common in women than in men (4: 1). Causes are fibromuskuläe dysplasia, a portal hypertension, many pregnancies, a perforating or blunt abdominal trauma, pancreatitis and infection. A hepatic arterial aneurysm is more common in women than in men (2: 1). They arise because of a previous abdominal trauma of unauthorized i.v. Drug abuse, a media degeneration of the arterial wall or periarterieller inflammation. can renal artery aneurysms dissect or rupture and cause acute closures (renal artery and renal artery occlusion: Acute renal artery occlusion). Symptoms and signs The symptoms are variable. Aneurysms of the subclavian artery, local pain, a pulsating feeling, venous thrombosis or edema (due to compression of adjacent veins), distal ischemic symptoms, transient ischemic attacks, stroke, hoarseness or impaired motor or sensory function (due to nerve compression recurrent laryngeal nerve or plexus) cause. Aneurysms of the superior mesenteric artery can cause abdominal pain and ischemic colitis. Regardless of the location of mycotic and inflammatory aneurysms may cause local pain and cause systemic infections (eg. As fever, malaise and weight loss). Diagnostic ultrasound or CT Most aneurysms of the side branches of the aorta are not diagnosed before rupture, although calcified asymptomatic and occult aneurysms can be detected on the X-ray absorption or other imaging procedures that are performed for other reasons. Ultrasound or CT are usually used to detect aneurysms of the side branches of the aorta or confirm. Angiography may be used as required, which are assumed that they exist because of the aneurysm or embolism to evaluate distal. Open therapy intervention, sometimes endovascular stent graft The treatment of choice is the surgical removal and replacement with a graft. An endovascular surgery is an option for some patients. The decision for supplying asymptomatic aneurysms, due to the risk of rupture, the extent and location of the aneurysm and the perioperative risk. The surgical treatment of aneurysms of the subclavian artery can (if present) include the removal of a neck rib prior to surgery. For aneurysms of the A. splanchnica the risk of rupture and a fatal outcome is up to 10%, and v. a. in women of childbearing age and in patients with hepatic aneurysms increases (> 35%). Elective care of aneurysms A. splanchnica is therefore indicated in women of childbearing age, in symptomatic aneurysms of other ages and hepatic aneurysms. In aneurysms of the splenic artery, the surgical treatment in the ligature of the artery without arterial reconstruction or aneurysm exclusion and vascular reconstruction there. Depending on the location of the aneurysm, a splenectomy may be required. The treatment of mycotic aneurysms is to aggressive antibiotic therapy, which is directed against the specific pathogen. Basically, these aneurysms need to be rehabilitated and surgically.
