Anesthesia case management for endovascular aortic aneurysm repair
AANA Journal
|June 7, 2014
Summary
Endovascular aortic repair (EVAR) offers a less invasive option for abdominal aortic aneurysms, reducing risks like organ damage and blood loss. Careful anesthetic management is crucial for patient safety during this procedure.
Area of Science:
- Cardiovascular Surgery
- Vascular Medicine
- Anesthesiology
Background:
- Increasing life expectancy and obesity rates are driving a rise in aortic and microvascular diseases.
- Endovascular Aortic Repair (EVAR) provides a less invasive treatment option for abdominal aortic aneurysms, especially for patients with poor surgical candidacy.
- EVAR avoids aortic cross-clamping, minimizing hemodynamic instability and inflammatory responses.
Purpose of the Study:
- To review the anesthetic considerations for Endovascular Aortic Repair (EVAR).
- To highlight the benefits and potential complications associated with EVAR.
- To emphasize the importance of understanding the perioperative process for comprehensive patient care.
Main Methods:
- Review of current literature on EVAR procedures and anesthetic techniques.
- Analysis of the physiological effects of EVAR compared to traditional open surgery.
- Examination of common complications and their management during EVAR.
Main Results:
- EVAR significantly reduces risks of myocardial ischemia, acute kidney injury, mesenteric ischemia, and blood loss compared to open surgery.
- Potential complications of EVAR include cerebral/myocardial ischemia, hemorrhage, access vessel damage, and endoleak.
- Local anesthesia with monitored anesthetic care is the predominant anesthetic approach for EVAR.
Conclusions:
- EVAR is a valuable therapeutic option for abdominal aortic aneurysms, offering reduced perioperative morbidity.
- Anesthesiologists must be aware of EVAR's unique benefits and potential complications.
- Comprehensive understanding of the surgical and perioperative aspects is essential for optimal anesthetic management and patient outcomes.

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...

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.

445
A nurse managing a patient with aortic regurgitation begins with a comprehensive assessment, including a review of the patient's medical history, family history, and lifestyle factors. During the cardiac examination, the nurse listens for heart sounds and checks for signs of valve abnormalities. The nurse also observes for symptoms such as dyspnea, orthopnea, and paroxysmal nocturnal dyspnea and assesses the patient's endurance and daily activity tolerance.Based on the findings, the nurse...

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
