Aneurysm III: Interprofessional Care

422
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.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Surgery
  • Interventional Radiology

Background:

  • Acute type B aortic dissection (ATBD) is a life-threatening condition requiring timely intervention.
  • Endovascular repair offers a minimally invasive treatment option for ATBD.
  • Evaluating the outcomes of endovascular repair in a large cohort is crucial for clinical practice.

Purpose of the Study:

  • To report the experience and outcomes of endovascular repair for acute type B aortic dissection (ATBD).
  • To assess the safety, feasibility, and efficacy of this treatment modality.
  • To analyze perioperative findings and long-term follow-up results.

Main Methods:

  • Retrospective analysis of 125 ATBD patients undergoing endovascular repair with stent-graft.
  • Inclusion of demographic data, operation details, perioperative findings, and follow-up results.
  • Analysis of procedural success, complications, costs, and mortality rates.

Main Results:

  • Successful stent-graft implantation in all 125 patients, with 135 devices used.
  • No perioperative mortality; major adverse events included renal infarction, stroke, and renal dysfunction.
  • Mean follow-up of 23.5 months, with three reported deaths and no re-interventions.
  • Higher hospital costs for complicated ATBD cases compared to uncomplicated ones.

Conclusions:

  • Endovascular repair is a safe and feasible treatment for ATBD.
  • Emergency repair for complicated ATBD yields satisfactory results, though associated with increased costs.
  • The procedure demonstrates good long-term outcomes with no need for re-intervention in this cohort.
