Prosthetic aortic arch replacement. A new experimental technique.

An experimental method for rapid replacement of the transverse aortic arch is presented. Branched intraluminal prostheses were fashioned of varying sizes containing ascending and descending aortic limbs and branches for the brachiocephalic and subclavian vessels. Rigid rings were sewn into the ends to allow rapid fixation of the grafts using extraluminal ligatures.

Massive hemoptysis in patients with cystic fibrosis: three case reports and a protocol for clinical management.

The clinical management of massive hemoptysis in patients with cystic fibrosis proceeds according to the following paradigm. The site of bleeding is identified by bronchoscopy, ideally under general anesthesia. Then selective bronchial arteriography is performed.
