The large blood vessels in the heart like being inflated, bulging into a “ball”, continue to expand, may burst hemorrhage. Hankow’s Song dad every day “carrying” this “untimely bomb”, every day fearful. The day before yesterday, the hospital vascular surgery experts, in the old man’s blood vessels installed on the “chimney”, cleverly excluded the crisis. Father Song is 78 years old, suffering from hypertension for many years, is an “old patient”. Three years ago, the detection of abdominal aortic aneurysm, then in the hospital vascular surgery by endovascular treatment, the risk of aneurysm rupture bleeding. A week ago, Dad’s body review, accidentally found a large blood vessel outside the heart – thoracic aorta “aneurysm”, about 7 cm in diameter, worried about the “aneurysm” broken, asked the doctor to hurry He was worried that the “tumor” would break and asked the doctor to remove the “heart problem”. Detailed examination revealed that the location of the hemangioma was “tricky”, located in the aortic arch, where three branch arteries supplying blood to the brain and upper extremities were divided, making surgery extremely risky and difficult. If the traditional method is adopted to implant a stent to seal the aneurysm, it will block the nearby left subclavian artery, which is an important vascular channel from the aorta to the cerebellum and the left upper limb. How to seal the hemangioma and at the same time ensure the adjacent blood vessels are open, He Tao, director of vascular surgery, thought of the latest international “chimney technology”. After careful preparation, this special surgery was performed the morning before yesterday. Director He made a tiny incision at the root of the old man’s left thigh and used a catheter to send a laminated stent all the way into the thoracic aorta to block the diseased hemangioma from the normal blood vessels; then a “window” was opened in the stent to insert a “chimney “A small cylinder-shaped stent was implanted to connect the left subclavian artery and open a special channel to ensure the blood supply to the brain and the left upper limb. ”The chimney technique is currently one of the more advanced endovascular treatment techniques in international medicine, which requires very high operating skills from doctors and is currently only carried out in very few hospitals in China.” The director introduced, in simple terms, that is, to build two stents in the aorta, that is, in the implantation of a stent to close the aneurysm, and then set aside a certain gap from between the stent and the vessel to join another tiny stent, forming a ‘chimney structure’ in the plan, which can ensure that the patient’s whole body blood flow is smooth and the organs do not appear ischemic state. It also solves aneurysms that are prone to rupture. However, this technique does not apply to all aneurysm patients, and doctors will tailor the minimally invasive treatment to the location and characteristics of the patient’s aneurysm. ”An aneurysm is not the same thing as a tumor, which is not strictly speaking an aneurysm. It is not a tumor in the strictest sense of the word, but rather a ball-shaped aneurysm caused by an injury to an artery that is abnormally dilated and expanded by the impact of high-pressure blood flow. The tumor is like a ball, which is constantly ‘inflated’ by branch blood vessels, and will continue to expand. The mortality rate of patients exceeds 90 percent.” The director introduced that the causes of aneurysms are complex, except for congenital factors such as congenital dysplasia of the arteries, which are mostly related to atherosclerosis, hypertension and hyperlipidemia later in life. Experts remind that since aneurysms are not painful and symptomatic in the early stage, many patients are discovered accidentally when they are examined for other diseases, and some are even discovered only when the aneurysm suddenly breaks and becomes life-threatening. Once an aneurysm is diagnosed, especially if it is more than 5 cm in diameter, it must be treated at the hospital as soon as possible. If there is sudden pain in the chest and back or abdomen, be alert to the possibility that the aneurysm will rupture and send it to the hospital as soon as possible.
