Aneurysm artery ligation

Various methods of ligating arteries are used to slow and coagulate the blood flow in the tumor sac to achieve the purpose of curing aneurysms. But because the collateral artery communicates with the tumor sac, the results are often unsuccessful or often relapsed. In addition, aneurysm sac resection is performed, after all blood vessels leading to the sac are ligated, the tumor is completely removed. Generally speaking, with sufficient collateral circulation and sympathetic ganglionectomy, this operation can cure aneurysms and is safer. But when peeling off the tumor sac, it will inevitably destroy part of the collateral blood flow. Although the more important distal arterial tissues are free from necrosis, long-term chronic ischemia often occurs after surgery, so it is mainly suitable for less important blood vessels, and the nerves and other tissues near the tumor sac are easy to separate (such as the elbow Or arteries below the knee joint, etc.). After resection of tumor sacs in other parts, vascular transplantation should be sought to restore arterial blood flow.
