Background: The management of symptomatic abdominal aortic aneurysms (AAA) remains a surgical challenge.

Objectives: To compare the outcomes of endovascular aneurysm repair (EVAR) versus open surgical repair (OSR) in patients with symptomatic AAA.

Methods: Patients treated for symptomatic AAA between April 2020 and April 2025 were retrospectively analyzed, comparing perioperative mortality and major adverse events between EVAR and OSR.

Results: A total of 494 AAA patients were identified, 49 (9.9%) were symptomatic (40 [81.6%] EVAR group, 9 [18.4%] OSR group). Patients undergoing OSR had a higher rate of juxtarenal involvement (OSR 6/9 [66.7%] vs. EVAR 3/40 [7.5%]; P < 0.001). Any signs of rupture were more prevalent in the EVAR group (27/40 [67.5%] vs. OSR 2/9 [22.2%]; P = 0.013). Technical success was achieved in 83.7% (n=41/49). In-hospital mortality was 22.4% (n=11/49), with no difference between groups (EVAR 9/40 [22.5%] vs. OSR 2/9 [22.2%]; P = 0.986). At logistic regression analysis, open repair was associated with a significantly higher risk of major complications (odds ratio [OR] 16.9, 95% confidence interval [95%CI] 1.79–158.3, P = 0.013), and a shock index > 0.9 remained an independent predictor of intra-hospital mortality (OR 372.5, 95%CI 1.58-87889.4, P = 0.034). During a mean follow-up of 28.8 ± 18.6 months, late mortality was 18.4% (n=7/38). Estimated survival analysis over 60 months did not demonstrate a significant difference between groups (log-rank test, P = 0.317).

Conclusions: Both EVAR and OSR yield satisfactory technical outcomes. Hemodynamic instability at presentation remains a critical predictor of mortality.

Objectives: To assess the results of endovascular revascularization for lower extremity ischemia in dialysis patients.

Methods: We conducted a retrospective review of all dialysis patients who underwent endovascular treatment for critical limb ischemia (CLI) in our institution between 2007 and 2011. Data collected included comorbidities, clinical presentation, anatomic distribution of vascular lesions, amputation and survival rates.

Results: We identified 50 limbs (41 patients). Indications included: gangrene in 22%, non-healing wounds in 45%, rest pain in 31%, and debilitating claudication in 4%. Mean follow-up was 12 months (1–51 months). Nineteen patients required amputations. Freedom from amputation at 5 years was 40%. Factors associated with amputation included non-healing wounds or gangrene (68% and 36% respectively) and diabetes (P < 0.05). The survival rate was 80% after 5 years.

Conclusions:  Despite improvement in endovascular techniques for lower extremity revascularization, the incidence of limb salvage among dialysis patients remains poor, resulting in a high rate of major amputations.
