BACKGROUND Women have poorer outcomes after vascular surgery as compared to men as shown by studies recently. Frailty is also an independent risk factor for postoperative morbidity and mortality. This study examines the interplay of gender and frailty on outcomes after infrainguinal vascular procedures. MATERIALS AND METHODS The American College of Surgeons National Surgical Quality Improvement Program database was used to identify all patients who underwent infrainguinal vascular procedures from 2005-2012. Frailty was measured using a modified frailty index (mFI; derived from the Canadian Study of Health and Aging). Univariate and multivariate analysis were performed to investigate the association of preoperative frailty and gender, on postoperative outcomes. RESULTS Of 24,645 patients (92% open, 8% endovascular), there were 533 deaths (2.2%) and 6198 (25.1%) major complications within 30 d postoperatively. Women were more frail (mean mFI = 0.269) than men (mean mFI = 0.259; P < 0.001). Women and frail patients (mFI>0.25) were more likely to have a major morbidity (P < 0.001) or mortality (P < 0.001) with the highest risk in frail women. On multivariate logistic regression analysis, female gender and increasing mFI were independently significantly associated with mortality (P < 0.05) as well as major complications. The interaction of gender and frailty in multivariate analysis showed the highest adjusted 30-d mortality and morbidity in frail females at 2.8% and 30.1%, respectively and that was significantly higher (P < 0.001) than nonfrail males, nonfrail females and frail males. CONCLUSIONS Female gender and frailty are both associated with increased risk of complications and death following infrainguinal vascular procedures with the highest risk in frail females. Further studies are needed to explore the mechanisms of interaction of gender and frailty and its effect on long-term outcomes for peripheral vascular disease.

Inferior gluteal artery pseudoaneurysm 37 years after transpelvic gunshot wound

Vascular injury secondary to blunt or penetrating trauma may result in pseudoaneurysm. Most injuries are recognized acutely following trauma, although cases of missed injury have been reported. Delay from initial injury to diagnosis of pseudoaneurysm usually ranges from weeks to months, and rarely exceeds a year [1,2]. We report a case of post-traumatic inferior gluteal artery pseudoaneurysm diagnosed 37 years after a gunshot injury to the pelvis and successfully treated with transcatheter embolization.

BACKGROUND Post-traumatic pulmonary embolic events are associated with significant morbidity. Computed tomographic (CT) measurements can be predictive of right ventricular (RV) dysfunction after pulmonary embolus. However, it remains unclear whether these physiologic effects or clinical outcomes differ between early (<48 hours) vs late (≥48 hours) post-traumatic pulmonary embolism (PE). METHODS All patients with traumatic injury and CT evidence of PE between 2008 and 2013 were identified. The study population was divided into 2 groups based on the time of diagnosis of the PE. The primary outcome was PE-related mortality. RESULTS Fifty patients were identified (14 early PE and 36 late PE). Patients sustaining a late PE had a higher PE-related mortality rate (16.7% vs 0%), larger RV diameters, RV/left ventricular diameter ratios, RV volumes, and RV/left ventricular volume ratios (all P < .05). CONCLUSIONS Early post-traumatic PE appears to be associated with fewer RV physiologic changes than late post-traumatic PE and may be representative of primary pulmonary thrombosis. It remains to be seen whether early CT findings of PE should be managed according to previously established guidelines for embolic disease.
