Aneurysm III: Interprofessional Care

434
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.

Summary
This summary is machine-generated.

Endovascular repair is expanding to treat the entire aorta, offering alternatives to open surgery for complex aortic diseases. While effective for many conditions, its role in uncomplicated Type B aortic dissection remains debated.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Medical Device Technology

Background:

  • Open repair remains standard for ascending and arch aorta pathologies.
  • Endovascular repair is increasingly used for high-risk patients and various aortic conditions.
  • Technological advancements have expanded endovascular applicability to the entire aorta.

Purpose of the Study:

  • To provide a comprehensive overview of current endovascular treatment options for the entire aorta.
  • To review the outcomes and established roles of various endovascular techniques.
  • To highlight emerging technologies and future directions in aortic repair.

Main Methods:

  • Review of endovascular repair techniques including hybrid procedures, chimney grafts, branched and fenestrated stent grafts.
  • Analysis of Thoracic Endovascular Repair (TEVAR) for descending aortic pathologies.
  • Evaluation of endovascular thoracoabdominal aortic aneurysm repair (EVAR) and infrarenal aneurysm repair techniques.
  • Discussion of Off-the-Shelf (OTS) devices, custom-made devices (CMD), and new sealing techniques like endovascular sealing (EVAS).

Main Results:

  • TEVAR is established for descending aortic pathologies, often superior to open repair.
  • Endovascular thoracoabdominal aortic aneurysm repair shows excellent short-term results and promising durability.
  • Fenestrated stent grafts are effective for pararenal aneurysms; OTS options show short-term feasibility for juxtarenal aneurysms.
  • New devices address anatomical limitations, and techniques like EVAS show promise, requiring long-term data.

Conclusions:

  • Endovascular repair offers diverse and evolving solutions for the entire aorta, from ascending to iliac arteries.
  • While established for many conditions, ongoing research and technological development are crucial for optimizing long-term outcomes.
  • Staging and device selection (OTS vs. CMD) are key considerations, especially in complex or emergency cases.
