The paravisceral and thoracic aorta are approached via a left-sided posteriolateral thoracotomy incision in approximately the 9th intercostal space. [10] For a thoracoabdominal aortic aneurysm, this approach can be extended to a median or paramedian abdominal incision to allow access to the iliac arteries.
Thoracoabdominal aortic aneurysms (TAAA) involve the aorta in the chest and abdomen. As such, major branch arteries to the head, arms, spinal cord, intestines, and kidneys may originate from the aneurysm. An endovascular repair of a TAAA is only possible if blood flow to these critical arteries is preserved.
A thoracotomy is a surgical procedure to gain access into the pleural space of the chest. [1] It is performed by surgeons (emergency physicians or paramedics under certain circumstances) to gain access to the thoracic organs, most commonly the heart, the lungs, or the esophagus, or for access to the thoracic aorta or the anterior spine (the latter may be necessary to access tumors in the spine).
Younger patients may develop aortic aneurysms of the thoracoabdominal aorta after an aortic dissection. [citation needed] It can also be caused by blunt injury. Atherosclerosis is the principal cause of descending aortic aneurysms, while aneurysms of the aortic arch may be due to dissection, atherosclerosis, or inflammation. [4]
When this type of surgery is done the chest is opened up. An incision will be made on the side of the chest where the affected area of the lung is located. The incision will be in between the two ribs located in that area. The surgeon will then be able to have access to the chest cavity once the two involved ribs have been pried open.
Air can leak out of the pleural space through an incision made for a thoracotomy to cause subcutaneous emphysema. [8] On infrequent occasions, the condition can result from dental surgery, usually due to use of high-speed tools that are air driven. [ 24 ]
The transaortic approach sees the catheter and valve inserted through the top of the right chest. Under general anesthesia, a small surgical incision is made alongside the right upper breastbone, followed by a small puncture of the aorta. The delivery system is then fed slowly to the correct position at the aortic valve.
Cardiothoracic surgery is the field of medicine involved in surgical treatment of organs inside the thoracic cavity — generally treatment of conditions of the heart (heart disease), lungs (lung disease), and other pleural or mediastinal structures.
