Summary
Open repair of juxtarenal aortic aneurysms (JAA) has acceptable mortality but often leads to renal dysfunction. Further research is needed to improve kidney function preservation during JAA repair.
Area of Science:
- Vascular Surgery
- Nephrology
- Surgical Outcomes
Background:
- Juxtarenal aortic aneurysms (JAA) represent a significant subset of abdominal aortic aneurysms.
- Open repair with suprarenal aortic cross-clamping remains the primary treatment for JAA, despite endovascular advances.
Purpose of the Study:
- To systematically review perioperative mortality and postoperative renal dysfunction after open repair of non-ruptured JAA.
Main Methods:
- Systematic literature search of Medline, Embase, and Cochrane databases (1966-2008).
- Inclusion of 21 non-randomized cohort studies (1256 patients).
- Assessment of heterogeneity, perioperative mortality, new-onset dialysis, and postoperative renal dysfunction using random effects models.
Main Results:
- Mean perioperative mortality was 2.9% (95% CI, 1.8-4.6).
- Mean incidence of new-onset dialysis was 3.3% (95% CI, 2.4-4.5).
- Postoperative renal dysfunction incidence varied widely (median 18%), with cold renal perfusion efficacy undetermined.
Conclusions:
- Open repair of non-ruptured JAA offers acceptable perioperative mortality.
- Postoperative renal dysfunction is a frequent complication following JAA repair.
- Strategies for renal function preservation require further investigation.

01:26Aneurysm III: Interprofessional Care
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. This...
01:25Aortic Regurgitation III: Medical Management
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...
01:22Aneurysm IV: Nursing Management
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...
