Surgery to replace the abdominal aortic artery under the kidneys

Abdominal aortic replacement surgery under the kidneys is a vascular surgery in which cases of abdominal aortic aneurysm under the kidneys and abdominal aortic obstruction under the kidneys.

1. Renal abdominal aortic replacement surgery is in place

The aortic is the largest artery that leads blood to feed parts of the body. When the aortic runs through the chest, it is called the thoracic aortic; when the aortic goes to the abdomen is called the abdominal aortic. In the position under the navel, the abdominal aortic divides into two branches of the pelvic artery, which provide blood to the lower veins.

Aortic aneurysm is an isentous dilated artery that is 50% larger in diameter than the normal size of that artery segment. Aortic aneurysms can occur in every position along the length of the aortic, however up to 80-85% of aortic aneurysms appear in the lower segment where the renal arteries should be called abdominal aortic aneurysms under the kidneys.

There are many causes of aortic aneurysms such as:

  • The artery's veins degenerate due to diseases such as arteriosclerosis, fibrous dysenterous diseases, necrosis of the artery members due to drugs,…
  • Aneurysms caused by bacterial, viral, non-infectious inflammation,…
  • Post-traumatic aneurysm and wound, aneurysm after arterial stenosis,…
  • Aneurysm due to some congenital diseases such as Marfan syndrome, Ehlers-Danlos syndrome,…

Aneurysms if not treated will always tend to gradually enlarge. Enlarged aneurysms can pinch the surrounding muscles, affecting the function of these bodies. The compression of the bulge also feeds the peripheral institutions of the bulge. The most dangerous complications of an aortic aneurysm are rupture of the aneurysm, which seriously threatens the patient's life.

Surgery to replace the abdominal aortic segment under the kidneys is aneurysm with an artificial passage in which cases:

  • Abdominal aortic aneurysms over 2.5 times the neck diameter above or above 5cm.
  • Abdominal aortic aneurysms have complications such as infection, threat of rupture, rupture, embolization of the veins of the dysenterosis.
  • Stage II or higher genus anemia in Leriche syndrome.

Surgery is not performed when the patient's condition is not allowed, the patient is too old to be weak or has many serious coordinated medical diseases. For patients with gastrointestinal cancer, the doctor must carefully consider the risk factors before doing so.

2. Surgical procedure for replacement of abdominal aortic artery under the kidneys

2.1. Pre-surgery preparation

Before the surgery, patients and their families will be clearly explained by medical staff about the condition, purpose of the surgery, complications, possible complications from the disease, due to the operation, due to the process of anesthesia, anesthesia or localized disease.

In order to prepare for the surgery, patients will be given some necessary tests such as: Straight chest x-ray, electrocardigraphy, cardiac ultrasound, respiratory function measurement, blood formula test, blood type, blood clot function, liver and kidney function assessment test, electrolyzer, urine test ,…

Patients will be fostered, improve their physical condition, balance disorders as a result of the disease or due to location, chronic diseases, age. Blood transfusion if the patient has a lot of anemia. Except for emergency surgery, medical diseases such as diabetes mellitus, hypertension,… will be treated stably before surgery. Patients will have to fast at least 8 hours before surgery, medical staff will guide the patient to remove, clean the surgical area and the whole body. Pre-surgery antibiotics may be used to fight infection or not.

2.2. Steps to proceed

The patient is lying on his back on the operating table, with pillows cushioned across the nose of the breast. The anesthesiology team conducts in-administration anesthesia, urination, gastric nostiousness, central intravenous transmission to monitor and compensate for the outbreak when necessary. Blood pressure, electrocardiitis are constantly monitored on the screen. The surgical team then carried out the disinfection, revealing the entire abdomen and two inguinal inguinals, spreading the acid.

Surgical steps:

  • Open the upper and lower umbilical white line abdomen, assess the organs in the abdomen (with lumps, ulcers or extra veses,…)
  • The doctor removes the intestines from the surgery, keeping warm and anti-tension when taking the intestines out of the abdomen. Then, open the leafitoneum into the position of the duodenal ligament, turn the corner of treitz and D4 duodenum to reveal the abdominal aortic artery close to the renal artery. Reveals the dependent lower vascular replacement position and bulging mass edging or clogged circuit length. May reveal the abdominal aortic segment of the pelvic fork, the original pelvic artery, the outer pelvic artery, or the lateral common femoral artery.
  • Patients are given a full-body heparin dose of 50UI/kg. The doctor clamps the upper and lower blood vessels of the lesion, proceeding to the abdominal aortic replacement:

Case of aneurysm: the doctor opens along the abdominal aortic aneurysm, stitches the bleeding of the vertebrae arteries. Replace the damaged artery segment with a straight or Y-shaped artificial artery depending on the case, proceed to stitch the blood vessels. Clamp the vascular cholera to remove the atherosclerosis plaques at the mouth. Restore circulation to the lower mesenterous artery if left colon anemia is suspected. After replacing the artificial vascular segment, the doctor proceedes to stitch the coat of the aneurysm to cover the artificial vascular segment.

Where the patient has Lerich syndrome: the doctor does not open the artery but clamps and stitches the clogged vascular segment, the next steps of the vascular replacement technique are carried out as in the case of aneurysm.

  • The surgeon will conduct a tour if necessary. Then stitch the leaf mesenterosis into, clean, stack the intestines, close the incisions to finish the surgery.

Iron deficiency anemia

Myeloid anemia is one of the post-surgical complications

3. Possible complications after abdominal aortic replacement surgery under the kidneys

  • Bleeding is a common symptom, if there is a hemolysis, a large hematoma patient will be prescribed an emergency hemorrhistry re-operation.
  • Post-embolic embolbol surgery: There are many causes that can cause post-surgery embolbolies such as not handling all the damage, using anti-freezing drugs is not reasonable or the technique of vascular recovery is not good. The doctor will prescribe re-surgery to restore the patient's circulation.
  • Multiple-degree infection, which can be local or full-body infection, from mild to severe. Treatment involves cutting only spasms, tightening vessels and bridges outside the anatomy, re-surgery,…
  • Intestinal anemia caused by the operation affects the lower mesenteritis artery and the pelvic artery in the sides, if there is peritonitis caused by intestinal necrosis, the doctor will prescribe a re-operation of the intestine.
  • Myeloid anemia due to surgery turns off the vertebrae arteries, treated with rehabilitation treatment.

Abdominal aortic replacement surgery under the kidneys was considered a benchmark for the treatment of abdominal aortic aneurysms under the kidneys for decades. However, arterial replacement surgery is a major specialist surgery, the duration of the surgery is prolonged, the risk of complications and mortality is high. Currently, endal intervention (stent-graft placement) and Hybrid surgical techniques have gradually replaced classic surgery in many cases.
