Viszeral Arterielle Aneurysmen 2016 Dr. Abidin Geles Welche Arterien sind betroffen: oo Truncus coeliacus oo A. lienalis oo A. hepatica communis oo A. gastrica sinister oo A. mesenterica superior et inferior oo A. renalis History oo 1809: first reported hepatic artery aneurysm as a post-mortem finding after ruptur(1) oo 1903: first successful operative repair by ligating(2) oo 1951, first successful VAA treatment by ligation and revascularization (3) (11) Wie gefährlich ist VAA? oo High incidence of rupture and hemorrhage (6) oo distribution of aneurysms among the visceral vessels : splenic artery (60%), hepatic artery (20%), superior mesenteric artery (5.5%), celiac artery (4%), gastric and gastroepiploic arteries (4%), jejunal, ileal, colic (3%), pancreaticoduodenal and pancreatic arteries (2%), gastroduodenal artery (1.5%), and inferior mesenteric artery (<1%) (7) oo The real incidence is unknown because most cases are asymptomatic (10) 1-2% of all vascular aneurysms (9) Visceral artery aneurysms are rare, with an incidence of just 0.01% to 0.2% oo Renal and splanchnic artery aneurysms 0.01% - 0.09% and 0.1% - 2% (4) oo 22% of reported visceral artery aneurysms are with rupture, resulting in 8.5% mortality rate (7,5) oo Mortality 21 % for hepatic artery aneurysms to 100% for celiac artery ones. (10) oo hepatic artery aneurysms with a high rupture risk of 80% (6) oo patients with hepatic aneurysms have also multiple aneurysms visceral (31%) and non-visceral circulation (42%)(6) oo splenic artery aneurysm rupture risk of 20% (6) oo mortality rate : 20% to 70% with the rupture of a VAA depending on the location and size (12) oo Ätiologie: Atherosclerosis (32% of cases), Medial degeneration/dysplasia (24%), Abdominal trauma (22%), Infection and inflammatory disease (10%), Connective tissue disorders (Marfan syndrome, Ehlers-Danlos syndrome, Osler-Weber-Rendu disease, fibromuscular dysplasia, Kawasaki, hereditary hemorrhagic telangiectasia, And hyperflow conditions (portal hypertension, pregnancy) indications for intervention: diameter => 1.5-2 cm, rapid growth of the aneurysm, symptomatic aneurysm, and the childbearing age (8) (6) Diagnosis oo Computed tomography oo Magnetic resonance oo Ultrasonography oo Arteriography Einteilung nach Symptomatik oo Asymptomatisch oo Symptomatisch oo Ruptur (6) (6) (6) (6) (6) Marone EM, Mascia D, Kahlberg A, et al. Is open repair still the gold standard in visceral artery aneurysm management? Ann Vasc Surg 2011; 25: 936-46. oo 94 patients with VAA/VAPA between 1988 and 2010, 74 patients managed with open traditional surgical technique, 20 with an endoluminal technique oo 100 % success with the open approach, 1 mortality (1,3%), and morbidity of 9.4% oo endovascular group had no perioperative mortality but a 10% peri-operative morbidity oo Conclusion: endovascular treatment is safe and feasible in selected patients, but incomplete exclusion may be observed, requiring late surgical conversion in a significant number of patients. Long-term results (high survival, low complication rate) confirm the durability of the surgical approach that in our experience remains the gold standard with satisfactory results, especially for aneurysms involving the visceral hilum.
