Because of the significant mortality associated with the conventional surgical approach to @entity1028 ( @entity1028 ) in the high risk @entity1 and in those with @entity1756 , we have developed a new approach to this problem, intraluminal @entity439 exclusion. This was achieved by an intraluminal prosthesis which approximated the diameter of the aorta above and below the @entity439 and is inserted through the femoral artery. The prosthesis consisted of biomedical grade elastomeric @entity2636 with a NITINOL and/or stainless steel frame and was designed in such a configuration that it could be compressed inside a 15 F catheter and then regain its original shape after being discharged inside the aorta. The @entity2636 prosthesis tolerated static pressures in excess of 300 Torr. Aneurysmal aortas were created in three adult @entity742 using large knitted Dacron pathches (6 X 9 cm) sewn onto a longitudinal aortotomy. After 4-6 weeks, an intraluminal prosthesis was passed transfemorally to the location of the @entity449 . Following satisfactory placement and expansion of the prosthesis, a laceration was produced in the aneurysmal wall. No bleeding developed, which confirmed the integrity of the prosthesis in excluding the @entity439 from the aorta proper. Pulsation in the iliac arteries indicated the presence of aortic blood flow through the prosthesis. Autopsy examination demonstrated directly that the prosthesis was open and that its two ends were fixed in the aorta above and below the @entity439 . The study has demonstrated that intraluminal @entity1028 exclusion could be achieved with an intraluminal @entity2636 prosthesis inserted through the femoral artery.
