Abdominal Aortic Aneurysm Treatment Abroad
Abdomen Aortic Aneurysm AAA Endovascular repair in Bangkok Thailand
Abdominal aortic aneurysm may not be noticeable, but deadly illness that is waiting to burst. We are fortuned to be living in a time where advanced medical technology and medical expertise can reduce the risk of death. Statistics have shown that 50 – 90% of patients overcome the disease. Our expert vascular surgeon shared with us his experience the treatment of abdominal aortic aneurysm. The aorta sends blood to each organ in the body, driven by the heart. Blood is supplied through the pulmonary artery, to the abdomen where the main artery splits into two just below the belly to supply the legs and pelvis. If there is any damage in this part of the blood vessel, the blood will seep out and will not be able to reach any other organ in the body, resulting in death. Abdominal aortic aneurysm is a condition where the blood vessel dilates to more than 1.5 – 2 cm in diameter. The cause is unclear; risk factors are smoking, hypertension, high blood cholesterol and genetics. There is a high occurrence among men and it affects men more than women.
The most fearsome fact is that the patient may not have any warning sign and when a symptom occurs, the artery is about to burst. The sign is simultaneous abdominal and back pain. Occasionally, the patient feels pounding due to the rupture inside the abdomen. If the patient is obese, this situation may not be noticeable.
Treatment If the aneurysm is less than 5 cm, it may not require surgery. An aneurysm larger than 3 cm has to be checked annually, an aneurysm larger than 4 cm should be checked every 6 months. If it reaches 5 cm, the patient should consult a vascular surgeon for treatment plan. In case where the aneurysm grew at a rate faster than 5 mm in 6 months or 1 cm in one year or larger than 5.5 cm, there is a high risk that it may burst and surgery is required. Open Abdominal Surgery, which is generally known as a major surgery, is the standard type of surgery. The patient need to be a sleep by anesthetics and the incision will be from the sternum to the pelvis. A graft will be inserting to replace the aneurysm. The long-term result is good; the surgery can be time extensive and a higher risk for complications. Endovascular Aneurysm Repair is a minor surgery and a stent graft will be inserted in the femoral arteries on both legs near the groin area. This is a new type of surgery that requires specially trained surgeon to perform. The incision site is small and the patient does not need to be knocked out. It also decreases risk and blood loss. Short-term and medium-term results are quite effective, but routine follow up with the physician is still necessary to assess long-term results. Mortality rate within the first 30 days of asymptomatic endovascular aneurysm repair is 1 – 1.5%, which is three times less than open abdominal surgery. The patient’s general health and the anatomy of the aneurysm are assessed to decide treatment plan. For relatively healthy patients who are less than 60 years of age, open abdominal surgery will be performed. Patient’s age of 70 years are advised to have endovascular aneurysm repair. This group includes younger patients who may have other health conditions such as heart or lung diseases, as well as patients who may be at risk of complications. The treatment will be decides case by case.
