Endovascular treatment of traumatic rupture of thoracic aorta: long term results.

Background: The aim of this study was to evaluate the endovascular treatment of acute post-traumatic thoracic aorta rupture. Rupture of the thoracic aorta is caused in a majority of cases by blunt trauma of the chest as a result of motor vehicle accident. Hypovolemic shock due to massive hemorrhage leads to death in almost 90% of victims.

Lack of usefulness of ureteral reconstruction with free bladder mucosa flap in dogs confirmed by microangiography.

Background: There is a paucity of data addressing the blood supply in the surgically reconstructed ureter, and complete lack of microangiographic studies of the reconstructed ureter with the use of a free bladder mucosa flap. The present study evaluated the blood supply in the reconstructed dog ureter after a 5-centimeter segment resection, supplemented by a tube constructed from a free bladder mucosa flap.

Material And Methods: Female mongrel dogs (n=29) were used in this study.
