Sex-specific criteria for repair should be utilized in patients undergoing aortic aneurysm repair.
This study’s goal was determine if identifying inherent anatomic differences between sexes, aortic size index (ASI) and aortic height index (AHI) may provide an additional method for guiding treatment for abdominal aortic aneurysm (AAA) surgery. Females are more likely to undergo repair at smaller aortic diameter compared with male patients. The authors identified all patients who underwent AAA repair between 2003 and 2019 in the Vascular Quality Initiative database. The Dubois and Dubois formula was used to calculate body surface area; aortic diameter was divided by body surface area to calculate ASI, and aortic diameter was divided by height to calculate AHI. They identified 55,647 patients, of whom 12,664 were female (20%). For both types of repairs (intact and rupture), female patients were older, less likely to undergo endovascular aneurysm repair, and more likely to have comorbid conditions. Female patients underwent repair at smaller median aortic diameter compared with male patients for intact (5.4 vs 5.5 cm) and rupture repair (6.7 vs 7.7 cm). When they analyzed the cumulative distribution of rupture repair in male patients, they found that 12% of rupture repairs were performed at an aortic diameter below 5.5 cm, but to achieve the same proportion of rupture repair in female patients, the repair diameter was only 4.9 cm. When both ASI and AHI were used, female and male patients both reached 12% of rupture repair at an ASI of 2.7 cm/m(2) and an AHI of 3.0 cm/m.

Effect of sex on nadir hematocrit and rates of acute kidney injury in coronary artery bypass.
Researchers explored whether there a sex-related difference on nadir hematocrit and rates of acute kidney injury in coronary artery bypass. A prospective, observational study was conducted of 17,363 patients not on dialysis undergoing the procedure between 2011 and 2016 across 41 institutions from the Perfusion Measure and Outcomes registry. There was no sex-related differences found for nadir hematocrit or rates of acute kidney injury.

Gender disparities in vascular access surgical outcomes in elderly hemodialysis patients.
In this study, the investigators assessed clinically relevant arteriovenous fistulas (AVF) and arteriovenous grafts (AVG) surgical outcomes in elderly male and female patients initiating hemodialysis with a central venous catheter (CVC). The investigators concluded that while AVFs should be considered the preferred vascular access in most circumstances, clinical AVF surgical outcomes were uniformly worse in females. They suggest that clinicians should also consider AVGs as a viable alternative in elderly female patients initiating hemodialysis with a CVC to avoid extended CVC dependence.

Physiologic and psychological gender differences in bariatric surgery.
This paper aims to describe differences in bariatric surgery outcomes by gender and to understand the physiologic and psychological differences that may explain this gender gap. It concludes that, despite significantly lower weight loss and increased complication rates, males tend to have markedly higher satisfaction and psychological well-being scores than females.

The influence of gender on functional outcomes of lower extremity bypass.
The researchers aimed to evaluate the effect of gender on early and late procedural and functional outcomes of lower extremity bypass (LEB). They found that women have complication rates similar to men with inferior early and late functional outcomes after LEB. The reduced patency rates in women with critical limb ischemia did not translate into differences in limb salvage.
