Modified Harborview Risk Score improves ease in predicting mortality after ruptured abdominal aortic aneurysm repair.

Objective: The Harborview Risk Score (HRS) is a simple, accurate 4-point preoperative risk scoring system used to predict 30-day mortality following ruptured abdominal aortic aneurysm (rAAA) repair. The HRS assigns 1 point for each of the following: age >76 years, pH <7.2, creatinine >2 mg/dL, and any episode of severe hypotension (systolic blood pressure <70 mmHg).

Preoperative risk score accuracy confirmed in a modern ruptured abdominal aortic aneurysm experience.

Objective: Various risk score calculators used to predict 30-day mortality after treatment of ruptured abdominal aortic aneurysms (rAAAs) have produced mixed results regarding their usefulness and reproducibility. We prospectively validated the accuracy of our preoperative scoring system in a modern cohort of patients with rAAAs.

Methods: A retrospective review of all patients wiith rAAAs who had presented to a single academic center from January 2002 to December 2018 was performed.

A reliable method for renal volume measurement and its application in fenestrated endovascular aneurysm repair.

Objective: Renal volume has been shown to correlate with renal function. Renal volume and renal function both decline steadily in the sixth decade of life and beyond. We sought to assess (1) the inter-rater reliability for manually measuring renal volume using computed tomography and (2) change in renal volume over time as it relates to renal function in fenestrated endovascular aortic aneurysm repair (FEVAR).

Evaluation of the learning curve for fenestrated endovascular aneurysm repair.

Objective: The objective of this study was to evaluate the learning curve for fenestrated endovascular aortic aneurysm repair (FEVAR).

Methods: Data were collected prospectively on all FEVAR procedures conducted by a single surgeon between June 2007 and January 2015. During the study period, 136 FEVARs were performed, and this experience was divided into four quartiles each consisting of 34 cases.

Re-entry into the true lumen from the subintimal space.

Endovascular reconstruction of the femoral and popliteal arteries is replacing femoral-popliteal bypass. This is made possible by subintimal recanalization to manage long chronic total occlusions. Re-entry into the true lumen is the most challenging step in this process.
