Aortic Aneurysm

The aorta is the largest artery and carries blood from the heart to the body. Patients with aortic aneurysms have bulging in the aorta that may have the potential to rupture or dissect. The patients experience chest pain, weight loss, fever, and pulsatility in the abdomen.


Our Offerings

  • Arch aneurysms: The aortic arch is the section of the aorta closest to the heart. Patients may have bulging of the aorta at the site of the aortic arch. Patients with this condition experience coughing up blood, difficulty swallowing, and shortness of breath.
  • Descending Thoracic Aneurysms: The thoracic aorta is part of the aorta in the thoracic region. The descending thoracic aneurysm occurs in the thoracic aorta facing the legs. The majority of the patients do not experience any symptoms. Symptoms, if present, are hoarseness, cough, and back or chest pain.
  • Throacoabdominal Aortic Aneurysms: These are difficult-to-treat aneurysms due to the complexity of their location. This occurs in a section of the aorta that extends from the thoracic region to the abdomen.
  • Infrarenal and Iliac Aneurysms: Infrarenal aneurysms are present in the section of the abdominal aorta below the kidneys. An iIliac aneurysm is characterized by weakness and bulging of the iliac artery in the pelvis.
  • EVAR: Endovascular Aneurysm Repair (EVAR) is a minimally invasive surgery to treat the abdominal aneurysm. The procedure is performed under imaging guidance.
  • TEVAR: Thoracic endovascular aortic repair is a procedure that involves treating the aneurysm located in the upper section of the aorta.
  • Hybrid Procedures: Hybrid surgery is used to repair an aneurysm or other complex aortic disorders in patients at high risk for undergoing conventional surgery.
  • Fenestrated EVAR: It is a minimally invasive procedure for repairing the aorta by making small incisions in the groin while maintaining the blood flow to the kidneys and other organs. It is used for patients who are not eligible for EVAR.
  • Follow up with USG: Several guidelines recommend that patients with asymptomatic aneurysms be followed up with ultrasound at a scheduled period, depending upon the diameter of the aneurysm. For instance, follow-up is every six months if the diameter of the aneurysm is less than 4.5 cm.

What are the types of aneurysms?

The types of aneurysms are thoracic aneurysms, abdominal aneurysms, and thoracoabdominal aneurysms.

Is an aortic aneurysm a severe condition?

An aortic aneurysm, if stable, is not a severe health threat. However, more giant aneurysms have a high risk of rupture that may result in severe internal bleeding.
