Background: Identifying sex-related differences/variables associated with 30 day/1 year mortality in patients with chronic limb-threatening ischemia (CLTI). Methods: Multicenter/retrospective/observational study. A database was sent to all the Italian vascular surgeries to collect all the patients operated on for CLTI in 2019. Acute lower-limb ischemia and neuropathic-diabetic foot are not included. Follow-up: One year. Data on demographics/comorbidities, treatments/outcomes, and 30 day/1 year mortality were investigated. Results: Information on 2399 cases (69.8% men) from 36/143 (25.2%) centers. Median (IQR) age: 73 (66–80) and 79 (71–85) years for men/women, respectively (p < 0.0001). Women were more likely to be over 75 (63.2% vs. 40.1%, p = 0.0001). More men smokers (73.7% vs. 42.2%, p < 0.0001), are on hemodialysis (10.1% vs. 6.7%, p = 0.006), affected by diabetes (61.9% vs. 52.8%, p < 0.0001), dyslipidemia (69.3% vs. 61.3%, p < 0.0001), hypertension (91.8% vs. 88.5%, p = 0.011), coronaropathy (43.9% vs. 29.4%, p < 0.0001), bronchopneumopathy (37.1% vs. 25.6%, p < 0.0001), underwent more open/hybrid surgeries (37.9% vs. 28.8%, p < 0.0001), and minor amputations (22% vs. 13.7%, p < 0.0001). More women underwent endovascular revascularizations (61.6% vs. 55.2%, p = 0.004), major amputations (9.6% vs. 6.9%, p = 0.024), and obtained limb-salvage if with limited gangrene (50.8% vs. 44.9%, p = 0.017). Age > 75 (HR = 3.63, p = 0.003) is associated with 30 day mortality. Age > 75 (HR = 2.14, p < 0.0001), nephropathy (HR = 1.54, p < 0.0001), coronaropathy (HR = 1.26, p = 0.036), and infection/necrosis of the foot (dry, HR = 1.42, p = 0.040; wet, HR = 2.04, p < 0.0001) are associated with 1 year mortality. No sex-linked difference in mortality statistics. Conclusion: Women exhibit fewer comorbidities but are struck by CLTI when over 75, a factor associated with short- and mid-term mortality, explaining why mortality does not statistically differ between the sexes.

To determine outcomes of postdissection thoracoabdominal aneurysms by either open or endovascular repair with fenestrated or branched endografts.A systematic review was conducted for open or endovascular repair of postdissection thoracoabdominal aneurysms, between January 2009 and February 2020. A meta-analysis was performed for postoperative complications and both early and late mortality and reinterventions.Fifteen noncomparative studies (eight endovascular repair and seven open repair) were suitable for meta-analysis. Overall, 1337 patients were included, 1068 in the open repair group (73% male; mean age 58 years) and 269 in the endovascular repair group (79% male; mean age 65 years). The 30-day mortality was 6% for open repair vs 3% for endovascular repair (P = .35), whereas the 30-day reintervention rate was 3% for open repair vs 1% for endovascular repair (P = .66). The only significant difference was reported for 30-day respiratory complication rate (30% open repair vs 2% endovascular repair; P .01). The incidence of spinal cord ischemia was 9% for open repair vs 8% for endovascular repair (P = .95). The mean follow-up was 44 months: 48 months (range, 10-72 months) after open repair and 17 months (range, 12-25 months) after endovascular repair (P .01). Late aortic reinterventions were more frequent after endovascular repair (11% vs 32%; P .001). The late overall mortality rate was 19% for open repair vs 7% for endovascular repair (P = .08), whereas aortic-related mortality was 7% for open repair vs 3% for endovascular repair (P = .22).In the absence of comparative studies, this meta-analysis showed that endovascular repair seems to be a viable alternative for patients unfit for open repair.

The purpose of this study was to evaluate the long term results of endovascular aneurysm repair (EVAR) in patients with abdominal aortic aneurysm (AAA) and ectatic common iliac arteries (CIAs).In a retrospective analysis of a prospectively collected database in two high volume centres, patients with AAAs undergoing elective standard EVAR were divided into two groups: those with both CIA diameters18 mm, and those with at least one ectatic iliac artery (CIA ≥ 18 mm). Patients with an intentional external iliac artery landing zone were excluded. Primary outcomes were survival and freedom from re-intervention. Secondary end points were EVAR failure and iliac related endoleak and iliac re-intervention.From 2000 to 2015, 648 patients were included in the study, 277 (43%) had at least one CIA ≥ 18 mm. Pre-operative risk factors were similar between the two groups, with the exception of chronic renal insufficiency (p = .010) and cerebrovascular events (p = .040), which were higher in the ectatic CIA group. At 30 days from primary procedure, there was a higher rate of type Ib endoleak in patients with ectatic iliacs (p = .020). A statistically significant increase in the incidence of late type Ib endoleak in patients with ectatic iliac arteries was confirmed at a mean follow up of 74.8 months (p = .01). The need for iliac related re-intervention was higher in patients with CIAs ≥18 mm (odds ratio 1.94; 95% confidence interval 1.1-3.2).Ectatic iliac arteries are considered suitable landing zones for EVAR, although there is an increased risk of secondary interventions in time mainly due to late CIA dilation and secondary type Ib endoleak. Patients receiving EVAR with flared iliac limbs may benefit a more intensive surveillance to avoid late failures.
