What are the tupes of Aortic Aneurysm Surgery?
Types of Surgery : Technique of surgery and the approach depends on the site of thoracic or thoraco abdominal aortic aneuiysm. Initial preparations are same for all the cases. For monitoring arterial pressure left radian artery is cannulated for ascending aortic and arch aneurysm. For descending thoracic or thoraco abdominal aneurysm, the right radial artery is cannulated. If a left thoracotomy is needed, it is better to use a double lumen endobronchial tube so that single lung anaesthesia can be given.
Insertion of Swan-Ganz pulmonary arterial catheter helps in monitoring cardiac output and pulmonary artery pressure. If circulatory arrest is planned, thermister probes for monitoring nasopharyngeal and rectal temperatures are placed. TEE is another useful monitor for any such case. An aneurysm that has eroded sternum poses problem at the time of opening by a median sternotomy. Then cardio pulmonary bypass can be instituted by cannulation of femoral artery and vein. Hypothermia and low flow or even circulatory arrest is employed for sternotoiny.
