Aneurysm artery ligation

Various methods of ligating the artery are to slow down and condense the blood flow in the tumor sac to achieve the purpose of curing the aneurysm. However, because the collateral artery communicates with the tumor sac, the results are often unsuccessful or often relapse. Another aneurysmal cystectomy, after ligation of all the blood vessels leading to the tumor sac, the tumor was completely removed. In general, this procedure can cure an aneurysm and is safer when the collateral circulation is sufficient and combined with sympathectomy. However, when the tumor sac is removed, it will inevitably destroy part of the collateral blood supply. Although the more important arterial distal tissue can be prevented from necrosis, long-term chronic ischemia can often occur after surgery, so it is mainly suitable for non-important blood vessels, and the nerves and other tissues near the tumor sac are easily separated (such as elbows). Or small arteries below the knee joint, etc.). After resection of the tumor sac in other areas, vascular grafting should be sought to restore arterial blood flow. Treatment of diseases: ascending aortic aneurysm, thoracic and aortic aortic aneurysm Indication Arterial ligation is generally only used as a temporary measure, or when it is necessary (such as an aneurysm has been infected, the patient is not good at the time; or technical conditions are limited, no other surgery can be performed). Sometimes it can also be used as a radical preparatory step. Surgical procedure After ligation of the upper and lower arteries of the aneurysm, the tumor sac is incision, and the contents are removed, and then gauze is used for filling; or free or pedicled muscle can be transplanted into the sac to block the collateral circulation and improve the effect of ligation.
