Aneurysm resection and vascular transplantation

Although occlusive surgery can cure aneurysms, gangrene rarely occurs after the main arteries of the extremities are occluded, but its function is difficult to completely recover, and chronic ischemia (such as intermittent breakage, cold skin, edema, ulcers) is often left behind. , Muscle atrophy, etc.) signs. Therefore, the principle of the treatment of aneurysms of the main artery should be to strive to remove the tumor sac and repair the arteries. (1) Aneurysm resection and vascular transplantation (2) Aneurysm resection and arterial repair For small aneurysms, the wall of the tube can be sutured directly after the tumor sac is removed [Figure 2]; or wedge-shaped resection is performed transversely [Figure 3] . As long as some arterial walls are healthy, repair can be performed. (3) After aneurysm resection and arteriolar end-to-end anastomosis, small aneurysm resection, arterial defects within 2 to 3 cm, anastomosis at both ends should be the preferred method. You can also leave the tumor sac without resection and anastomosis at both ends. However, if the defect is too long, a blood vessel transplant is required.
