Seven pigs underwent subsequent intraarterial DSA. Both surgical procedure and transarterial angiography were carried out under anesthesia with mechanical ventilation after tracheal intubation.Results Bifurcation aneurysms were surgically created in ten animals. After surgical procedure, 2 pigs died from aneurysmal rupture and one died of anesthetic overdose. DSA was performed in all other 7 animals and it demonstrated 6 patent aneurysms and one occluded. Three of the 6 patent bifurcation aneurysms were wide necked and 3 were narrow necked.Conclusion Arterial bifurcation aneurysm model can be successfully constructed in swine. It will provide us with an in vivo model to observe and develop therapeutic devices, teach endovascular techniques, and study aneurysmal hemodynamics.展开更多
