What are Aortic Aneurysms?
The aorta is the main blood vessel that carries blood from the heart to the rest of the body.
An aortic aneurysm is an abnormal bulging or ballooning in a weakened area of the aorta wall. Aneurysms can occur anywhere along the aorta but are commonly found in the abdominal and thoracic regions.
Symptoms
- Aortic aneurysms often do not cause symptoms until they reach a critical size, or rupture.
- Very often, aneurysms are detected incidentally- for example, when a scan is performed for an unrelated reason.
- The type of symptoms experienced largely depends on the exact location of the aneurysm (can occur anywhere along the aorta)
- Some individuals may experience chest or abdominal pain, back pain, or discomfort.
- Symptoms can also include shortness of breath, hoarseness, and difficulty swallowing if the aneurysm presses on nearby structures.
Causes
- The primary cause is usually the weakening of the aortic wall, which can be attributed to factors like high blood pressure, atherosclerosis (hardening of the arteries), and genetic predisposition.
- Smoking, a family history of aneurysms, and certain connective tissue disorders can also increase the risk.
Complications
- The most severe complication is aneurysm rupture, which can lead to internal bleeding and is a life-threatening emergency.
- Blood clots may form within the aneurysm, these clots can fly off (embolise) to other parts of the body and cause blockage of blood supply to the legs or other critical organs.
- If left untreated, aneurysms can progressively enlarge and become more challenging to manage.
Diagnosis
- Diagnosis often involves imaging tests such as ultrasound or CT scans to visualize the size and location of the aneurysm.
- Regular monitoring is crucial to assess the aneurysm’s growth rate- this will guide treatment decisions.
Treatment Options
Treatment depends on the size, location, and overall health of the patient.
Surveillance
For smaller aneurysms with no symptoms, regular monitoring might be advised.
Medication
Blood pressure medications may be prescribed to reduce stress on the aortic wall.
Surgical Procedures
- Open Repair: A large incision is made to replace the weakened section with a synthetic graft.
- Endovascular Aneurysm Repair (EVAR): A minimally invasive procedure involving a stent-graft. Peri-operative risks are usually lower and recovery quicker.
Conclusion
Aortic aneurysms are a serious medical condition that requires careful monitoring and, in some cases, intervention to prevent life-threatening complications. If you suspect or are diagnosed with an aortic aneurysm, it is crucial to work closely with your vascular surgeon to determine the most suitable treatment plan based on your individual condition. Early detection and management can significantly improve outcomes and reduce the risk of rupture.

FAQ about Aortic Aneurysms
An aortic aneurysm is a bulge or enlargement in the aorta, the main blood vessel that delivers blood from your heart to the rest of your body. This condition can be serious as the wall of the aorta can weaken, leading to a risk of rupture. This leads to life-threatening internal bleeding.
Firstly, take a deep breath. It’s important to gather as much information as you can and discuss your concerns and treatment options with a specialist. Early diagnosis and management are key in dealing with aortic aneurysms. Dr. Lim and his team are here to support you every step of the way, providing compassionate care, detailed information, and expert medical advice to help you make informed decisions about your health.
The treatment for aortic aneurysms is multifaceted and based on various factors including size, location, and individual health conditions. Dr. Lim emphasizes a tailored approach to each patient’s condition. Treatment approaches include:
- Monitoring and Medication:
Small aneurysms may be closely monitored with regular imaging tests and medications to manage blood pressure and prevent the aneurysm from growing.
An EVAR is a minimally invasive procedure that involves placing a stent-graft within the aneurysm to reinforce the weakened section of the aorta. This procedure can be suitable for patients with certain types and locations of aneurysms and is associated with shorter recovery times compared to open surgery.
This is a more traditional method where an incision is made in the abdomen to access the aneurysm. The weakened section of the aorta is replaced with a synthetic graft. Open repair is highly effective but involves a longer recovery period.
Not all aortic aneurysms require surgery. Small aneurysms are often monitored with regular imaging tests to check for any changes in size or symptoms. Surgery is generally recommended when the aneurysm is large, growing quickly, or causing symptoms like backaches or abdominal pain. Dr. Lim will assess your particular situation and help you decide the best course of action based on your overall health, lifestyle, and personal preferences.
Dr. Lim meticulously evaluates several factors to determine the most appropriate surgical approach for your aortic aneurysm. These include the size, shape, and location of the aneurysm, your age, medical history, and overall health. Endovascular aneurysm repair (EVAR) is a minimally invasive option suitable for some patients, while open surgery may be necessary for others. Dr. Lim will discuss the benefits and risks of each option with you and collaborate with you to decide the best treatment plan tailored to your needs.
A rupture of an aortic aneurysm is a medical emergency and can lead to severe internal bleeding and potentially be life-threatening. It’s crucial to seek immediate medical attention if you experience sudden, intense, and persistent abdominal or back pain, as this could be indicative of a ruptured aortic aneurysm.
