Anesthetic considerations for endovascular aortic repair

Area of Science:

• Cardiovascular Surgery
• Anesthesiology
• Vascular Medicine

Background:

• Endovascular aortic repair (EVAR) presents an alternative to traditional open surgery for aortic pathologies.
• The evolution of EVAR devices and techniques has expanded treatment options.
• Understanding perioperative management is crucial for successful EVAR outcomes.

Purpose of the Study:

• To review available endovascular aortic repair devices.
• To discuss outcomes associated with endovascular aortic repair.
• To outline anesthetic considerations and potential complications during EVAR.

Main Methods:

• Review of current endovascular aortic repair devices and their applications.
• Analysis of reported outcomes following endovascular aortic repair.
• Discussion of anesthetic management strategies, including hemodynamic optimization and ventricular asystole induction.
• Identification of risks such as arterial rupture, paraplegia, and post-implantation syndrome.

Main Results:

• Various devices are available for endovascular aortic repair, with outcomes varying by device and patient factors.
• Anesthetic management is tailored to the specific device and deployment site.
• Hemodynamic optimization and potential induction of ventricular asystole are key considerations.
• Risks include arterial rupture, requiring resuscitation facilities, and potential postoperative paraplegia necessitating spinal cord protection.
• Post-implantation syndrome is a risk in patients with large aneurysms.

Conclusions:

• Endovascular aortic repair is a viable alternative to conventional surgery, requiring specialized anesthetic management.
• Careful patient selection and monitoring are essential to mitigate risks like paraplegia and post-implantation syndrome.
• Preparedness for complications, including arterial rupture, is critical for patient safety during EVAR.
