Nasopharyngeal angiofibroma (NA) is a rare vascular benign nonencapsulated neoplasm, characterized by local aggressiveness and destructive potential, typically diagnosed in adolescent males. We report a case of NA affecting a 15-year-old male that presented with a persistent nasal obstruction and epistaxis with 1 year of evolution. Clinical and radiological patterns pointed out a differential diagnosis of NA.

The reduced size should allow application to most distal coronary vessels currently grafted. This technology may be useful in off-pump and minimally invasive surgical approaches to coronary revascularization.

Recently, special interest has developed in mechanical anastomotic devices to facilitate minimal invasive techniques or limited access surgery. The experience with two series of patients undergoing coronary artery bypass grafting (CABG) using the St.

To explore this possibility we developed methods for adenoviral-mediated gene transfer to canine saphenous veins.
Methods: During a single procedure, autogenous canine saphenous vein segments were transduced ex vivo and used as coronary artery bypass grafts.
Background: Coronary anastomoses are currently primarily carried out with the use of running nonabsorbable sutures. Recently, a renewed interest has developed for facilitated mechanical anastomotic devices especially for minimal invasive techniques or limited access surgery. The initial experience with the first successful creation of mechanical vein-to-coronary artery anastomoses in humans is reported.
View Article and Find Full Text PDFObjectives: A new device designed to create proximal vein graft anastomoses to the aorta in coronary artery bypass grafting was recently developed by the St Jude Medical Anastomotic Technology Group (Minneapolis, Minn). This new anastomosis system consists of a nickel-titanium (nitinol) connector, an aortic cutter, and a delivery device.
Methods: The loading of the vein on the aortic connector and its delivery to the aorta are described.
Background: A new stainless steel anastomosis device developed by St. Jude Medical Cardiovascular Group was studied in a canine model.
Methods: In 12 dogs, coronary saphenous vein grafts were made to the left anterior descending coronary artery and to the circumflex coronary artery; one anastomosis was completed with the St.
Increasing interest in minimally invasive cardiac surgical procedures has generated a renewed interest in facilitated methods to create vascular anastomosis. These devices, in order to be viable, must perform equally or better than sutures. An extensive review of the literature was performed on the different ways to create a mechanical vascular anastomosis.
