Aortic Aneurysm Surgery Success Rate

What Happens During Ascending Aortic Aneurysm Repair

What is the success rate for aortic root replacement surgery?

Your surgeon will replace the weakened part of your aorta with a graft . If other parts of your aorta are damaged, like the aortic root or aortic arch, your surgeon can fix those parts at the same time. Your surgeon may also replace your aortic valve if needed. The extent of surgery depends on your aortas condition as well as your medical history and family history.

Once youre moved to the operating room, your care team will help you feel comfortable and relaxed. Youll be given general anesthesia that puts you to sleep during the surgery. During parts of your surgery, youll be on a heart-lung machine . Your care team may also use deep hypothermic circulatory arrest to stop your blood circulation.

Your surgery will include the following steps:

  • Incision. Your surgeon will make an incision in the front of your chest .
  • Clamping. Your surgeon will use a tool called an aortic cross-clamp to pause blood flow through your ascending aorta.
  • Graft insertion. Your surgeon will replace the bulging section of your ascending aorta with a tube called a graft. This graft functions as a new lining for your artery. Your surgeon will sew the graft in place with stitches.
  • Closure. Your surgeon will close the incision in your chest with stitches or staples.
  • This surgery usually takes three to four hours. The time can vary based on how many issues need to be fixed.

    What Is An Abdominal Aortic Aneurysm Repair

    Your doctor may recommend abdominal aortic aneurysm repair to treatan aneurysm. An aneurysm is a bulging, weak spot in the aorta that may beat risk for rupturing. In this case, the aneurysm is in part of the aortathat is in the abdomen. Repair of an AAA may be done in one of two ways:

    • Open repair. For this surgery, your doctor makes a large incision in the abdomen to expose the aorta. Once he or she has opened the abdomen, a graft can be used to repair the aneurysm. Open repair remains the standard procedure for an abdominal aortic aneurysm repair.

    • Endovascular aneurysm repair . This is a minimally invasive option. This means it is done without a large incision. Instead, the doctor makes a small incision in the groin. He or she will insert special instruments through a catheter in an artery in the groin and thread them up to the aneurysm. At the aneurysm, your doctor will place the stent and graft to support the aneurysm.

    The doctor will determine which procedure is right for y

    Minimally Invasive Surgery for Aortic Aneurysms | Q& A

    Johns Hopkins expert vascular surgeons can provide minimally-invasive aneurysm repair, with shorter hospital stays and quicker recovery. They even perform a hybrid surgery for those who arent eligible for the least invasive procedure but cant have open surgery.

    How A Thoracic Aortic Aneurysm Is Treated

    A leaking thoracic aneurysm is an emergency and requires immediate treatment with either surgery or placement of a special type of covered aortic stent .

    The location of the aneurysm partly determines whether or not a stent-graft can be used to treat the aneurysm. It is important to treat aneurysms before they rupture, because once a thoracic aneurysm ruptures chances of survival fall to 50%. However, when patients are treated before the aneurysm ruptures, chances of survival are greater than 90%.

    During traditional open surgery, the aneurysm is opened and an artificial blood vessel or graft is sewn in its place. The aneurysm itself is not necessarily removed. However, our preferred way to treat thoracic aortic aneurysms is with stent-grafts, which can be done without major chest surgery in some patients.

    What Are The Types Of Thoracic Aortic Aneurysm Surgery

    There are two procedures to treat a thoracic aortic aneurysm:

    • Open thoracic aneurysm repair is an open surgery that requires a long incision along the side of your chest. Your surgeon removes the damaged portion of the aorta and replaces it with synthetic material .
    • Thoracic endovascular aortic repair is a minimally invasive procedure. Your surgeon reaches your aorta by placing a small, hollow tube through a blood vessel in your groin. They use the catheter to place a small mesh device that repairs the diseased portion of the aorta and restores proper blood flow.

    Symptoms Of A Thoracic Aortic Aneurysm

    Update on Abdominal Aortic Aneurysm Research: From Clinical to Genetic ...

    Most thoracic aortic aneurysms develop slowly over time and can remain remarkably asymptomatic until they actually leak, tear or rupture, which is often an emergency.

    As a result, most thoracic aortic aneurysms are diagnosed incidentally when someone undergoes a CT scan for some other reason. Thoracic aneurysms can sometimes be detected on a plain chest X-ray or when someone undergoes an ultrasound examination of their heart.

    When a thoracic aneurysm ruptures, the patient will often experience excruciating chest or back pain and may have difficulty breathing and may lose consciousness. Sometimes patients will notice an unusual back pain that they have never felt before, prior to the aneurysm actually leaking. Rarely, some aneurysms grow large enough to put pressure on certain nerves, or the airway or food pipe , and cause symptoms such as hoarseness, wheezing or difficulty swallowing.

    Preparing For The Surgery

    Before proceeding with the surgery, the doctor will perform a series of tests to identify the location and the size of an aneurysm. Depending on the condition, the surgeon will provide instructions to prepare for the operation. These guidelines include a healthy diet that helps in reducing the blood pressure and procedures to avoid smoking.

    What Happens During Thoracic Aortic Aneurysm Surgery

    In open thoracic aortic aneurysm repair, your surgeon:

  • Makes a large incision along the side of your chest.
  • Uses special tools to stop blood flow temporarily in the affected segment of your aorta.
  • Replaces the damaged section of your aorta with a synthetic graft.
  • Closes the incision with stitches.
  • During TEVAR, your provider:

  • Inserts a catheter and special wires through an artery in your groin.
  • Guides the catheter to your thoracic aorta.
  • Injects a contrast dye through the catheter so they can see your thoracic aorta clearly.
  • Uses CT or X-ray guidance to position the stent accurately.
  • Removes the catheter and wires and places a bandage over the incision area in your groin.

    Here Are A Few To Consider

    An aortic aneurysm is a bulge in the aorta, the largest blood vessel in the body. Aneurysms can form in the chest or abdomen . Sixty percent of aortic aneurysms involve the part of the aorta that extends immediately from the heart. Forty percent occur in the segment extending into the abdomen. The larger the aneurysm grows, the greater the chance it may dissect or rupture, which is life-threatening.

    Abdominal aortic aneurysms , or aneurysms in the abdominal part of the aorta, are the 13th leading cause of death in the United States and the 10th leading cause of death in men.

    NewYork-Presbyterians aortic surgeons had a 100% success rate in treating abdominal aneurysms involving the arteries of the kidneys .

    This success has become possible through the creation of a comprehensive Aortic Center at NewYork-Presbyterian/Columbia University Medical Center. This integrated program, directed jointly by cardiac and vascular surgeons in the Department of Surgery, features a 24/7 on-call team of cardiologists, vascular surgeons, cardiac surgeons, and interventionalists who specialize in the treatment of aortic aneurysms and dissections. This team is carefully coordinated by Tracy Andrews, DNP, ACNP, a highly experienced cardiac surgical nurse practitioner, who rapidly assesses incoming patients, obtains critical test results, and directs patients to the appropriate specialists for treatment.

    How Is Repair Of An Aortic Aneurysm Accomplished

    Aortic Aneurysm Patient Success Story: Tom Tansor

    There are a number of ways to repair or replace the portion of an aorta damaged by an aneurysm. Which option is used will depend on such factors as where your aneurysm is located , how big it is, and the overall state of your health. Your surgeon will determine which of the following procedures is most appropriate in your particular situation:

    • Endovascular surgery may be an option for some patients. This minimally invasive procedure involves making a couple of tiny incisions in blood vessels in your groin inserting long, thin tubes known as a catheters through the vessels to the point where your aneurysm is located and then using X-ray guidance and long, thin instruments threaded through the catheters to place a little mesh tube known as a stent graft inside the affected portion of the vessel. In circumstances when it is appropriate, endovascular surgery can sometimes be done with the patient under local rather than general anesthesia in addition, it usually does not require hypothermic circulatory arrest or use of a heart-lung bypass machine. Since this approach avoids the need to open the chest at all, it usually results in much faster healing.

    What Is Thoracic Aortic Aneurysm Surgery

    Thoracic aortic aneurysm surgery is a treatment for a bulge in the part of your aorta that runs through your chest . Your aorta is the large artery that carries blood from your heart throughout the rest of your body. It starts at your heart and extends through your chest and abdomen before it ends at your pelvis.

    Aneurysms occur when there is a weak spot in one of your arteries. This weakening can lead to ballooning or expansion in that section of your artery. Thoracic aortic aneurysms are rare, affecting only about 1 in every 10,000 people.

    Proteolysis Metalloproteinases And Inflammation

    In AAA, the aortic media appears to degrade by way of a proteolytic process. This implies an increase in the concentration of proteolytic enzymes relative to the concentration of their inhibitors in the abdominal aorta as the individual ages.

    Some research has focused on the role of the metalloproteinases, a group of zinc-dependent enzymes responsible for tissue remodeling. Reports have documented increased expression and activity of matrix metalloproteinases in people with AAAs. MMPs and other proteases have been shown to be secreted into the extracellular matrix of AAAs by macrophages and aortic smooth-muscle cells.

    MMPs and their inhibitors are present in normal aortic tissue and are responsible for vessel-wall remodeling. Aneurysmal tissue tends to demonstrate increased MMP activity and decreased inhibitor activity, which favor the degradation of elastin and collagen. The mechanism that tips the balance in favor of degradation of elastin and collagen in the aortic wall of AAAs by MMPs and other proteases is not yet known.

    Upon histologic examination, AAAs demonstrate a chronic adventitial and medial inflammatory infiltrate. Infiltration of AAAs with lymphocytes and macrophages may trigger protease activation via various cytokines .

    Summary:
    For patients undergoing repair of intact abdominal aortic aneurysms, long-term survival has improved in recent decades. For patients undergoing repair of ruptured abdominal aortic aneurysms, short-term survival has improved and long-term survival has remained stable. A less invasive procedure, endovascular aneurysm repair, is allowing surgical repair for older people with additional health problems.

    Long-term survival for patients undergoing surgical repair of intact abdominal aortic aneurysms has improved in recent decades, according to a Swedish study reported in Circulation: Journal of the American Heart Association.

    An abdominal aortic aneurysm is a bulge in the main artery leading away from the heart that occurs below the kidneys . If such a bulge bursts, hemorrhaging can occur within the abdominal cavity. These aneurysms can be monitored or corrected surgically while the bulge is intact, but require emergency surgery when ruptured.

    In the new study, researchers examined patient outcomes of 8,663 operations to repair intact aneurysms and 4,171 to repair ruptured ones from 1987 to 2005. The researchers used the patients relative five-year survival rate as a key measure. That rate excluded patients who died within 90 days of surgery and was based on a comparison of expected survival rates in a broader population with the same demographic characteristics.

    What Happens Before Aorta Surgery

    How Dangerous Is Abdominal Aortic Aneurysm Surgery?

    Tell your provider about all of the medicines you take, even those without a prescription. They may ask you to stop taking some of them for a specific amount of time before surgery.

    Go to any appointments that your provider requires, such as for an electrocardiogram, imaging or bloodwork. This gives them valuable information theyll need for your surgery.

    Ask someone to drive you to and from the hospital. You also may want someone to stay with you for the first few days after you get home from the hospital.

    Ask your employer if you can receive disability coverage while you recover.

    Get instructions about how to prepare, such as when to stop eating the night before surgery.

    How long does aorta surgery take?

    The time needed for aorta surgery depends on which procedure youre having, among other factors. An abdominal aortic aneurysm surgery takes three to six hours. However, if its done with an endovascular method, it takes about two to five hours.

    Examples of other surgery times:

    • A thoracic endovascular aortic repair: about two hours.
    • A more complex repair: three to eight hours.
    • An aortic dissection repair: six hours.

    Developing Case Mix Groups

    The development of the case-mix groups was based on the anatomy of the AA disease , admission method , ruptured vs intact AA, type of the procedure , and a subgroup of patients dying in-hospital from AA with no previous AA operation. The anatomy of the AA disease was identified by specific OPCS codes that differentiate complex AA procedures from infra-renal AA procedures . There were further issues that had to be resolved in the development of case-mix groups.

    Categorisation of elective and emergency

    There were several potential methods to distinguish elective or emergency AA cases. Admission method in HES data defines elective and emergency admissions, OPCS codes differentiate between elective and emergency procedures and ICD-10 codes can describe whether AA is intact or ruptured . Table presents cross-tabulation of these three methods for the index AA operation episodes. The table demonstrate the degree of overlap between these methods in identifying elective and emergency episodes in the HES dataset.

    Table 1 Cross tabulation of different rules to categorise elective and emergency in index episodes

    Categorisation of ruptured aortic aneurysm

    There were 27,359 ruptured AA cases identified using the ICD10 diagnosis codes for ruptured AA of these 1092 were ruptured complex AA repair cases , 15,717 were ruptured infra-renal repair cases , and 10,750 were cases of rupture with no definitive repair operation .

    Aneurysm Diameters At Baseline And Growth Over Time

    The largest aneurysm was in the DTA for 636 ITT patients and 89 CM patients. Mean maximum diameter at baseline was 5.6 cm in ITT patients and 6.3 cm in CM patients. After excluding scans using techniques other than CT or MRI and one scan dated 20 years before ETTAA, 1767 scans in 882 patients were included. Times between first and subsequent scans ranged from 3 days to 7.35 years.

    The final model describing diameter measurement trajectories in the absence of treatment is shown in . Average diameter in the DTA at baseline for a person of average age, with no comorbidities was 5.57 cm . At first scan, larger aneurysms were found for older patients , connective tissue disorders , and COPD . At baseline, adjusting for age, scan type, and comorbidities, the mean difference between maximum diameter in upper and lower sections of the thoracic aorta was small .

    Diagnosing An Aortic Aneurysm

    With the help of x-ray, angiogram, MRI scan, and CT scan, it is possible for the surgeon to locate an aorta aneurysm along with its size and shape. These are non-invasive procedures, and the results are precise and immediate. Along with the results, the doctor will consider the age factor of the patient, family history, and other conditions before opting for the surgery.

    Risks Of Preventive Surgery

    Does Your Aortic Aneurysm Need Surgery?

    Surgery on an aneurysm can lead to serious complications, especially lung complications and damage to the heart. It may even lead to death, for example due to circulatory collapse. The risk of complications is determined by various factors. One of these is the patients general health. For instance, people who have cardiovascular disease have a higher risk. Sometimes further surgery is needed right after surgery or at a later date.

    So doctors estimate the patients risk of complications. Reasons not to have preventive surgery include the following:

    • The person has other serious conditions, such as heart disease.
    • The persons general health is so poor that a procedure seems to be too risky, for example due to old age and the associated problems.

    Surgery is considered if the risk of the aneurysm unexpectedly rupturing in the next few years seems to outweigh the risks associated with the surgery.

    How Long Does It Take To Recover From Ascending Aortic Aneurysm Repair

    Most people stay in the hospital for up to 10 days. But you may need more time depending on your condition. You may also benefit from cardiac rehab after you leave the hospital. This helps you regain your strength and independence.

    Full recovery usually takes four to six weeks. But some people need several months to fully get back to normal.

    What Lifestyle Changes Should I Make After My Surgery

    Its important to make lifestyle changes to reduce your risk of future heart problems. These include:

    • Eating a heart-healthy diet. Especially cut down on sodium .
    • Exercise Ask your provider whats safe and ideal for you.
    • If you smoke or use tobacco products, its time to quit. Smoking and tobacco products like vaping damage your arteries and causes many other health problems.
    • Manage high blood pressure, high cholesterol and diabetes.
    • Join a support group to share your experiences with others who are in your shoes.
