Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).

Abstract: The clinical, radiographic and histologic features of sixty-one popliteal aneurysms in 36 patients are reviewed. Twenty-seven aneurysms were thrombosed and presented with an acutely ischaemic limb or the sudden onset of severe claudication. Thirty-four patent aneurysms presented with either ischaemic ulceration or claudication due to tibial artery disease or were asymptomatic with normal distal pulses. Thrombosis made reconstruction difficult and at times required a femoro-tibial graft. In others reconstruction was not possible leading to amputation either as primary treatment or following failed revascularization. In patent aneurysms one or more tibial arteries were frequently occluded. It is postulated that obliterative atheromatous disease of the tibial vessels and the slow flow through the aneurysmal vessels is responsible for the high incidence of thrombosis, poor graft patency and a high amputation rate.
Which is the apt title for the abstract? option1: The significance of tibial artery disease in the management of popliteal aneurysms. option2: Medical software regulation: why now? [editorial]
