Objectives: The purpose was to assess whether combining patient reported scores (VVSymQ®) and physician reported scores (VCSS) stratifies disease severity in C2 patients. Methods: Consecutive patients were pooled from the VANISH-1 and VANISH-2 cohorts. VCSS and VVSymQ® were calculated for each patient. The relationship between scoring systems was evaluated using Pearson's correlation and frequency distribution analysis. Results: Two-hundred and ten C2 limbs were included. Scoring systems demonstrated: VVSymQ®: mean = 8.72; VCSS: mean = 6.32; correlation (r = 0.22, p = 0.05). Frequency distribution analysis demonstrated 61.4% of patients had low VVSymQ® and low VCSS; 31.3% had elevated VVSymQ® and increased VCSS; 7.3% were inconsistent with C2 disease. Strict concordance analysis revealed 40.5% had VVSymQ® (< 9)/VCSS (0-6), 18.6% had VVSymQ® (≥ 9)/VCSS (7-9), and 2.9% had VVSymQ® (≥9)/VCSS (≥10). Conclusions: For combined elevated VVSymQ® and VCSS, moderate/severe disease is corroborated, and intervention may be indicated. For combined lower scores, the disease severity is mild and conservative therapy is more appropriate. [ABSTRACT FROM AUTHOR]

Endovascular aneurysm repair has improved outcomes for ruptured abdominal aortic aneurysms (rAAA) compared with open repair. We examined the impact of aorto-uni-iliac (AUI) vs standard bifurcated endograft configuration on outcomes in rAAA. Patients 18 years or older in the Vascular Quality Initiative database who underwent endovascular aneurysm repair for rAAA from January 2011 to April 2020 were included. Patient characteristics were analyzed by graft configuration: AUI or standard bifurcated. Primary and secondary outcomes included 30-day mortality, postoperative major adverse events (myocardial infarction, stroke, heart failure, mesenteric ischemia, lower extremity embolization, dialysis requirement, reoperation, pneumonia, or reintubation), and 1-year mortality. A subset propensity-score matched cohort was also analyzed. We included 2717 patients: 151 had AUI and 2566 had standard bifurcated repair. There was no significant difference between the groups in terms of age, major medical comorbidities, anatomic aortic neck characteristics, or rates of conversion to open repair. Patients who underwent AUI were more commonly female (30% vs 22%, P =.011) and had a history of congestive heart failure (19% vs 12%, P =.013). Perioperatively, patients who underwent AUI had a significantly higher incidence of cardiac arrest (15% vs 7%, P <.001), greater intraoperative blood loss (1.3 L vs 0.6 L, P <.001), longer operative duration (218 minutes vs 138 minutes, P <.0001), higher incidence of major adverse events (46.3% vs 33.3%, P =.001), and prolonged intensive care unit (7 vs 4.7 days, P =.0006) and overall hospital length of stay (11.4 vs 8.1 days, P =.0003). Kaplan-Meier survival analyses demonstrated significant differences in 30-day (31.1% vs 20.2%, log-rank P =.001) and 1-year mortality (41.7% vs 27.7%, log-rank P =.001). The propensity-score matched cohort demonstrated similar results. The AUI configuration for rAAA appears to be implemented in a sicker cohort of patients and is associated with worse perioperative and 1-year outcomes compared with a bifurcated graft configuration, which was also seen on propensity-matched analysis. Standard bifurcated graft configuration may be the preferred approach in the management of rAAA unless AUI configuration is mandated by patient anatomy or other extenuating circumstances.

The existing renal artery aneurysm (RAA) literature is largely composed of reports of patients who underwent intervention. The objective of this study was to review the natural history of RAA. This single-institution retrospective analysis studied all patients with RAA diagnosed by computed tomography imaging between 2015 and 2019, identified by our institutional radiology database. Imaging, demographic, and clinical data were obtained via the electronic medical record. He growth rate was calculated for all patients with radiological follow-up. The cohort consists of 331 patients with 338 RAAs. Most patients were female (61.3%), with 11 (3.3%) of childbearing age. The mean age at diagnosis was 71.5 years (range, 24-99 years). Medical comorbidities included hypertension (73.7%), prior smoking (34.4%), and connective tissue disease (3.9%). Imaging indications included abdominal pain (33.5%), unrelated follow-up (29.6%), and follow-up of an RAA initially diagnosed before the study period (10.7%). Right RAA (61.9%) was more common than left (35.1%); 3% of patients had bilateral RAA. The mean diameter at diagnosis was 12.9 ± 5.9 mm. Size distribution included lesions measuring less than <15 mm (69.9%), 15 to 25 mm (27.1%), and more than 25 mm (3.0%). Anatomic locations included the distal RA (26.7%), renal hilum (42.4%), and mid-RA (13.1%). The majority were true aneurysms (98%); of these, 72.3% were fusiform and 27.7% were saccular. Additional characteristics included calcification (82.2%), thrombus (15.9%), and dissection (0.9%). Associated findings included aortic atherosclerosis (65.6%), additional visceral aneurysms (7.3%), and abdominal aortic aneurysm (5.7%). The mean clinical follow-up among 281 patients was 41.0 ± 24.0 months. The mean radiological follow-up among 137 patients was 26.0 ± 21.4 months. Of these, 43 patients (31.4%) experienced growth, with mean growth rate of 0.23 ± 4.7 mm/year; the remainder remained stable in size. Eight patients eventually underwent intervention (5 endovascular), with the most common indications including size criteria (4/8) and symptom development (3/8). No patient developed rupture. On multivariate analysis, obesity (P =.04) was significantly associated with growth. An initial diameter of more than 25 mm was significantly associated with subsequent intervention (P =.006), but was not significantly associated with growth. Four of five RAAs with an initial diameter 30 mm or greater did not undergo intervention. The mean clinical follow-up for these patients was 24 months; none developed rupture and two remained stable in size. This large institutional cohort found that the majority of RAAs remained stable in size, with few patients meeting indications for repair based on societal guidelines. Current guidelines recommending intervention for asymptomatic aneurysms more than 30 mm seem to be appropriate given their slow progression. [ABSTRACT FROM AUTHOR]
