What is TEVAR in Aortic Dissection?

Acute type B aortic dissection begins distal to the left subclavian artery. It is often managed medically, but intervention is required when complicated (malperfusion, uncontrolled pain, rapid aortic growth, rupture).

Thoracic endovascular aortic repair (TEVAR) uses a stent graft delivered through the femoral artery to seal the proximal entry tear, preserve the true lumen and promote thrombosis of the false lumen. It is preferred in complicated acute and subacute dissection.

TEVAR requires follow-up for risks such as paraplegia, retrograde type A dissection, graft infection and endoleak. Lifelong surveillance is mandatory after the procedure.

Symptoms

Sudden severe back or chest pain
Hypertensive emergency
Malperfusion (bowel, kidney, limb)
Paraplegia
Rapid hemodynamic decline
Neurologic findings
Loss of peripheral pulses

Risk Factors

Uncontrolled hypertension
Connective tissue disease (Marfan, Loeys-Dietz)
Bicuspid aortic valve
Prior aortic surgery
Trauma
Aortic aneurysm
Genetic predisposition

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Tearing back pain
  • Severe hypertensive crisis
  • Cold extremity
  • Altered consciousness
  • Abdominal pain with shock
  • Prior history of dissection

Hypertension (High Blood Pressure)

Kardiyoloji

Hypertension is a condition in which blood pressure readings remain above 140/90 mmHg; early treatment helps prevent serious complications.

Coronary Artery Disease

Kardiyoloji

Narrowing of the coronary arteries due to atherosclerosis can cause chest pain (angina) and heart attack.

Heart Failure

Kardiyoloji

Heart failure is a chronic cardiac condition characterized by shortness of breath, leg swelling, and fatigue.

Heart Attack (Myocardial Infarction)

Kardiyoloji

A heart attack is a medical emergency; because heart muscle is lost by the minute, immediate intervention saves lives.

Atrial Fibrillation

Kardiyoloji

Atrial fibrillation is a common arrhythmia characterized by an irregular heartbeat and increased risk of stroke.

Heart Palpitations

Kardiyoloji

Palpitations are usually due to benign causes, but underlying cardiac rhythm disorders must be ruled out.

Heart Valve Diseases

Kardiyoloji

Valve stenosis or regurgitation increases the workload of the heart and, over time, can lead to heart failure.

Aortic Aneurysm

Kardiyoloji

Aortic aneurysms are often silent; early diagnosis allows treatment before rupture (a life-threatening tear).
