Aorta surgery is a medical procedure aimed at addressing issues with the body’s largest artery, the aorta. This vital artery plays a crucial role in transporting oxygen-rich blood from the heart to the rest of the body. It originates at the heart and extends down to the abdomen, ensuring the distribution of oxygenated blood throughout the entire body.
Aneurysms are caused by the aorta’s walls being weak and stretched out as a result of a high blood flow through it. Aortic dissection, which is also caused by high blood pressure, occurs when the layers of the aorta wall are forced apart.
The aorta’s capacity to deliver blood containing oxygen to the body’s cells and tissues is compromised by these problems. Life-threatening injury can occur in specific circumstances.
When an aneurysm increases in size by approximately half an inch each year, healthcare providers may consider surgical intervention. The timing for surgery on a slow growing aneurysm can vary. However, given the heightened risk of dissections and ruptures when the aneurysm reaches around 2.4 inches, most surgeons opt for surgical intervention when the aneurysm’s diameter is between 2 to 2.2 inches.
Before the patient’s aorta wall is in danger of breaking, aortic surgery is required. Aortic dissection may occur if their aorta wall becomes overly strained.
Aortic dilation (widening) and aortic dissection (tearing), both of which increase the risk of potential life-threatening events, are caused by a variety of diseases and disorders.
Aortic dissection and aneurysms may be caused by the following conditions:
Aortic aneurysms (weakened, bulging artery walls in the aorta) come in a variety of forms that can be treated with aorta surgery. Anywhere along the aorta, including the following, can experience an aneurysm:
Aortic dissection, or the separation of the layers of the aorta wall, is another condition that can be treated with aorta surgery. A tear in the aorta’s inner layer allows blood to pass through. The condition poses a danger to life.
Aorta surgery is essential for individuals who have congenital heart conditions like coarctation (narrowing) of the aorta or transposition (reversal) of the great arteries since they require corrective procedures.
The specific type of aorta procedure performed on the patient will influence the associated risks.
Risks associated with repairing an aortic dissection may include:
Depending on the circumstances, a healthcare provider can perform aortic surgery using various approaches or methods, such as:
Endovascular surgery involves surgical procedures conducted by surgeons using slender, long tubes called catheters within the patient’s body. Healthcare providers use catheters to guide a stent graft through small incisions in the groin, leading to the location of the aneurysm within the blood vessels.
A short wire-mesh tube (scaffold) known as an endovascular stent graft strengthens the aorta’s weak area. The graft permits blood to travel through it without pressing on the aneurysm by firmly sealing the region with the artery above and below the aneurysm.
The following benefits of endovascular treatment for thoracic aneurysms:
Ensure that the healthcare provider is informed about all medications the patient is using, including over-the-counter ones. Prior to surgery, they may advise the patient to discontinue certain medications for a specified duration.
Attend all scheduled appointments, including those for imaging, bloodwork, and electrocardiograms, as directed by the healthcare provider. They get important information from this that they can use during the operation.
Request a ride to and from the hospital. They might also want someone to stay with them the first few days after they return from the hospital.
Learn what to do in advance, such as when to stop eating the night before surgery.
The type of aorta problem the patient has will determine the surgical approach, as will the approach the healthcare provider takes.
The patient’s treatment will commence in the ICU, where they might regain consciousness with a breathing tube in place. Once they regain the ability to breathe independently, the tube will be removed. Afterward, as the patient’s condition allows, they will gradually start ambulating. When a patient’s condition no longer necessitates intensive care, they will be transferred to a different room.
Once a patient meets the criteria for discharge, they will have a discussion with their healthcare provider regarding the possibility of returning home.
People often stay in the hospital for a week following aorta surgery for an aneurysm. Additionally, they require at least a month of recovery. A patient who undergoes minimally invasive surgery could only need one or two days in the hospital.
Patients can generally expect a hospital stay of approximately one week following an aortic dissection, although it may extend to three or four weeks if complications arise. The survival rate after aortic surgery is influenced by factors such as the type of surgery performed and other variables.
Survival rates are typically higher following elective (preventive) aorta surgery compared to emergency surgery. For instance, 99% of patients undergoing elective endovascular surgery for abdominal aortic aneurysms survive 30 days post-surgery. Surgical excision for the same aneurysm yields a 96% to 98% 30-day survival rate. However, when an aneurysm ruptures, only around 50% to 70% of patients survive the surgery.
After one year, the survival rates for aortic arch and ascending aorta aneurysms ranged from 81% to 95%. They ranged from 60% to 73% after eight to ten years.
If a patient has any of the following symptoms, patient need to contact their healthcare provider:
Patients with an aortic aneurysm or dissection will need regular follow-up appointments with their healthcare provider. During these visits, the healthcare provider will monitor for potential complications, assess the stability of the aorta, and may recommend radiographic imaging through CT scans or MRI as part of the evaluation.
