Q: Abstract: During infragenicular bypass, internal occlusion of the distal vessel avoids unnecessary dissection and potentially damaging use of external clamps or vessel loops while improving exposure and patency. This technique is especially useful in patients with small or calcific vessels in whom distal reconstruction is necessary for limb salvage.

A: No

Q: Abstract: Disseminated intravascular coagulopathy (DIC) was demonstrated in a patient who underwent surgical thromboexclusion by blood flow reversal for dissecting aortic aneurysm. Large clots in the descending thoracic aorta and extra-anatomic bypass grafting might have been causative factors of the consumption coagulopathy. Low-dose heparin together with fresh-frozen plasma was effective; however, extreme caution should be adopted with such patients to minimize the development of DIC, because the factors responsible for the coagulation abnormalities are not removed in patients who undergo the surgical treatment of thromboexclusion.
