Summary
Delayed surgical repair is a viable strategy for acute thrombosed aortic dissection, reducing unnecessary operations. This approach demonstrated comparable survival and event-free rates for both Type A and Type B dissections.
Area of Science:
- Cardiovascular Surgery
- Vascular Medicine
- Thoracic Surgery
Context:
- Thrombosed aortic dissection treatment remains controversial.
- Initial management strategies vary, impacting patient outcomes.
- Retrospective analysis of acute thrombosed aortic dissection cases.
Purpose:
- To evaluate the efficacy of delayed surgical repair versus initial medical management for acute thrombosed aortic dissection.
- To compare outcomes between medically and surgically treated patients.
- To identify predictors for delayed surgical intervention.
Summary:
- Ninety-six patients with acute thrombosed aortic dissection (35 Type A, 61 Type B) were initially treated medically.
- Delayed surgery was performed for uncontrollable cardiac tamponade, recanalization, large ulcer-like projections, or aortic enlargement.
- Both Type A and Type B dissections showed similar 1- and 5-year survival and event-free rates, regardless of initial treatment strategy.
- A lower false-to-true lumen ratio (F/T ratio) was observed in operated Type A cases (31% vs. 51%).
- Operated Type B cases presented with a larger initial aortic size compared to non-operated cases.
Impact:
- Conservative management for thrombosed aortic dissection can decrease unnecessary surgeries.
- The strategy of delayed surgical repair is justified, offering a safe and effective alternative.
- Provides evidence supporting a more selective surgical approach in managing thrombosed aortic dissections.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
