What is an Aortic Dissection?

An aortic dissection occurs when a tear in the aorta's inner lining lets blood into the wall and separates its layers, creating a false lumen. The dissection may involve the ascending aorta, descending thoracic aorta, abdominal aorta, or multiple segments.

Aortic dissections are commonly classified as:

  • Type A: Involves the ascending aorta and may extend into the aortic root, arch, coronary arteries, or other branches.
  • Type B: Does not involve the ascending aorta and usually begins in the descending aorta.

A dissection can interfere with blood flow to the heart, brain, kidneys, intestines, spinal cord, or limbs and may cause complications such as rupture, cardiac tamponade, aortic valve leakage, stroke, or organ ischemia.

What is the Importance of Timely Treatment?

Aortic dissection can rapidly become life-threatening. A tear involving the ascending aorta can lead to rupture, cardiac tamponade, aortic regurgitation, coronary artery obstruction, stroke, or reduced blood flow to other organs.

Acute Type A aortic dissection requires immediate evaluation by an experienced aortic or cardiac surgical team, with emergency operative repair generally recommended. Patients who are stable enough for transfer may be transferred to a high-volume aortic centre with appropriate expertise.

What are the Common Symptoms of an Aortic Dissection?

  • Sudden, severe chest pain
  • Severe upper-back pain
  • Pain that may spread to the neck, jaw, abdomen, or back
  • Shortness of breath
  • Fainting or loss of consciousness
  • Sweating, weakness, or a feeling of impending illness
  • Stroke-like symptoms such as weakness, numbness, confusion, or difficulty speaking
  • Abdominal pain
  • Reduced blood flow to an arm or leg, which may cause pain, weakness, numbness, or a cold limb
  • Unequal blood pressure or pulses between limbs

Latest Research and Technologies in the Treatment of Aortic Dissection in Singapore

  • Modern management of aortic dissection focuses on rapid diagnosis, accurate anatomical assessment, specialised surgical or endovascular treatment, and intensive postoperative monitoring. CT angiography, echocardiography, and MRI are used when appropriate to define the location and extent of disease. Treatment may include open ascending aortic or arch repair, valve or aortic-root procedures, hybrid approaches, and endovascular techniques for selected descending-aorta dissections.

Treatment options for Aortic Dissection

Open Surgical Repair: Acute Type A aortic dissection generally requires emergency open surgery. The procedure may involve replacement of the ascending aorta, hemiarch or arch reconstruction, and repair of associated complications such as aortic regurgitation or coronary involvement.

Bentall Procedure : A Bentall procedure may be performed when the aortic root and aortic valve are significantly affected. It involves replacement of the aortic root and ascending aorta with a composite graft containing an artificial valve, with reimplantation of the coronary arteries into the graft.

Valve-Sparing Aortic Root Repair: In selected Type A dissections involving the aortic root, the native aortic valve may be preserved when appropriate. The dilated or dissected root is replaced or reconstructed while retaining the patient's own valve, when clinically appropriate.

Endovascular Repair (TEVAR): Thoracic endovascular aortic repair (TEVAR) may be considered for Type B dissection when complications such as rupture, malperfusion, persistent pain, uncontrolled hypertension, or other high-risk features are present and the anatomy is suitable.

  • Clinical assessment:
  • Symptom assessment: Sudden chest or back pain, pain radiation, shortness of breath, fainting, or neurological symptoms.
  • Blood pressure: Measurement in both arms to identify significant differences that may indicate impaired blood flow.
  • Pulse examination: Checking pulses in the arms and legs for differences or reduced blood flow.
  • Cardiovascular examination: Assessment for abnormal heart sounds, aortic regurgitation, or signs of cardiac complications.
  • Neurological assessment: Checking for weakness, numbness, confusion, speech difficulties, or other signs of stroke or reduced blood flow to the brain.
  • Organ and limb perfusion: Assessment for signs of reduced blood supply to the kidneys, intestines, spinal cord, or limbs.
  • Medical history: Review of hypertension, aortic aneurysm, previous aortic procedures, or known cardiovascular disease.
  • Family history: Assessment for a family history of aortic disease or inherited connective-tissue disorders.
  • Underlying conditions: Evaluation for conditions such as Marfan syndrome, other connective-tissue disorders, or bicuspid aortic valve.
  • Imaging Tests:
  • CT Angiography (CTA): Provides rapid, detailed images of the aorta and can identify the location and extent of the dissection and involvement of major branches.
  • Transesophageal Echocardiography (TEE): Provides detailed assessment of the ascending aorta, aortic root, valves, heart function, and complications such as pericardial effusion.
  • Transthoracic Echocardiography (TTE): Helps evaluate heart function, aortic valve regurgitation, and pericardial effusion, although it does not fully visualise the entire aorta.
  • MRI/MRA: Provides detailed aortic imaging and can be useful for selected patients, particularly during longer-term surveillance.

Frequently Asked Questions

Recovery varies considerably. After surgical repair, hospital recovery may be followed by several weeks or months of gradual physical rehabilitation. Long-term follow-up is required because the remaining or repaired aorta can develop later changes. Many patients need lifelong imaging surveillance.

Patients with an acute aortic dissection should not attempt to manage the condition through walking or exercise. It requires urgent medical assessment. After treatment, doctors generally reintroduce walking gradually as part of recovery.

Appropriate treatment centres may have advanced CT angiography, echocardiography, cardiac surgery, intensive care, and endovascular capabilities. However, technology and specialist expertise vary between centres, so patients should assess the specific facility and aortic team.

Some hospitals in Singapore have international-patient departments that may assist with appointment coordination, medical records, travel-related documentation, accommodation, interpretation, and follow-up arrangements. These services vary between hospitals and should not be considered a substitute for clinical assessment.

Rather than relying only on rankings, consider whether the centre has an experienced multidisciplinary aortic team, appropriate emergency facilities, cardiac and vascular surgical expertise, advanced imaging, intensive care, and the ability to provide both open and endovascular treatment when indicated. Experience with complex aortic disease and postoperative surveillance is also relevant.

No single success rate applies to all aortic dissections in Singapore. Outcomes depend on whether the dissection is Type A or Type B, the patient's condition at presentation, organ involvement, complications, treatment timing, surgical complexity, and the treating centre's experience and resources.

Experience varies by specialist and centre. Patients should look for teams with specific experience in aortic surgery and complex aortic disease rather than relying solely on general cardiac-surgery experience.

Treatment risks depend on the type of dissection and procedure performed. Possible complications include bleeding, stroke, kidney injury, infection, heart complications, neurological complications, organ malperfusion, recurrent or residual aortic disease, and the need for additional procedures.

A suspected aortic dissection is a medical emergency. Sudden severe chest or back pain, fainting, breathing difficulty, or neurological symptoms should prompt immediate emergency medical attention. Do not try to treat it at home or delay evaluation.

Aortic dissection does not typically cause physical deformities in the conventional sense. However, complications involving blood flow to the brain, spinal cord, or limbs can result in neurological or physical disability. Early treatment and appropriate management of complications are important.

Yes. Aortic dissection can affect quality of life through changes in physical activity, medications, blood-pressure control, and emotional well-being. Regular imaging and long-term follow-up may be required. With appropriate treatment and rehabilitation, many patients can gradually return to daily activities, although recovery varies depending on complications and residual aortic disease.

Yes. An untreated dissection can progress and cause rupture, organ malperfusion, stroke, heart failure, aortic valve problems, or death. Even after successful treatment, residual aortic disease may enlarge or change over time, which is why long-term imaging surveillance is important.

Risk reduction includes maintaining good blood-pressure control, avoiding smoking, managing cardiovascular risk factors, following prescribed treatment, and attending recommended imaging follow-up. People with inherited aortic conditions or a family history of aortic disease may require genetic assessment and screening of first-degree relatives.

Risk is higher in people with hypertension, thoracic aortic aneurysm, inherited connective-tissue disorders, bicuspid aortic valve with associated aortic disease, and a family history of aortic disease. Age and other cardiovascular risk factors can also contribute. Certain pregnancy-related conditions may increase risk in susceptible individuals.
