What is ロンドン脱⽑ surgery? ロンドン脱⽑ surgery is a minimally invasive method that is performed under local anesthesia. It deals with the treatment of disorders such as aneurysms of the abdominal artery or aorta, cardiovascular accidents, stenosis, obstructive arteriopathies, and other problems related to the vascular system. In the case of an aneurysm, the goal is to prevent the aneurysm sac from rupturing, and this is achieved through the use of special stents. In the treatment of cardiovascular accidents, endovascular surgery can remove occlusions from the arteries. Why is it done? It is often done to treat an aortic aneurysm. In the case of an abdominal aortic aneurysm, the aorta can become dilated as a result of improper lifestyles such as smoking, stress, lack of physical activity, and poor diet. When the aorta reaches and exceeds 5 cm in diameter (the correct value is 2 cm), it is advisable to perform ロンドン脱⽑ surgery to prevent rupture of the aneurysmal sac, so this surgery is preventive. What does it consist of? When ロンドン脱⽑ surgery is used to treat visceral artery aneurysms, the surgery is performed by inserting a catheter into the femoral aorta at the level of the groin through a small incision. The catheter is advanced to the aneurysm, where it attaches to the aorta and isolates the aneurysm sac from blood flow through the stent and from embolizing materials. In the event of a cardiovascular accident, the catheter can be inserted into the femoral artery and guided to the brain. Once the blood clot is reached, the catheter releases a stent that is used to release blood flow. When the stent is removed, it also drags the occlusion with it. Preparation for endovascular surgery: Endovascular surgery must be preceded by a series of tests to determine if the patient suffers from serious coagulopathies that could be fatal during surgery. The patient must also provide their complete medical history. Postoperative recovery: X-rays and ultrasounds are performed after the operation to check the result of the procedure. The patient can usually leave the hospital two days later and return to work about a week later, while full recovery can take up to a month. It is important that you carefully follow your doctor's instructions regarding medications to take and follow-up visits until you are fully recovered. Alternative treatments: Regarding the treatment of cardiovascular accidents, pharmacological treatment may be sufficient in one out of every three cases, but the volume of thrombi must be reduced.
