This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.ResultsIn accordance with the inclusion criteria, 17 articles discussing transcarotid approach EVAR were retrieved, encompassing 18 patients. Among these patients, 6 patients were related to ascending aortic disease, including 4 cases of pseudoaneurysms, 1 case of penetrating ulcer, and 1 case of dissection. 9 patients had descending aortic disease, comprising 6 aneurysms, 2 penetrating ulcers, and 1 pseudoaneurysm. There were 3 cases of abdominal aortic disease, including 2 aneurysms and 1 endoleak.

Further, the effect of center volume in fenestrated endografting on outcomes will be sought as this is ill defined. The data herein have the potential to affect referral patterns and locations of complex fenestrated aortic aneurysm care. If lower volume centers achieve equivalent outcomes to higher volume centers, then limiting access to a small number of centers may not be justified.MethodsVascular Quality Initiative (VQI) was utilized as the data source. Four adverse outcomes categories were investigated : (1) Lack of follow up data in the VQI database at 1 year postoperatively; (2) Thirty day operative mortality; (3) Composite perioperative adverse event outcome; and (4) Twelve month mortality. Social determinants of health exposure variables included rural status, non-metropolitan living area, highest and lowest decile and quintile area deprivation index, insurance status, and non-home living status. Designated categories were created for patients operated on in centers within the top 25% of case volume, centers in the bottom 25% of case volume, and in centers with less than 10 total fenestrated endograft cases. Univariable analyses were performed with Chi-squared testing for categorical variables and &lt;i&gt;t&lt;/i&gt; test for comparison of means. Multivariable binary logistic regression was performed to identify risks for the composite adverse perioperative event.ResultsThere was no statistically significant association with the composite adverse perioperative event category, 30-day mortality or 12-month mortality for any of the social determinants of health or center volume categories. Patients who live in rural areas (&lt;i&gt;P&lt;/i&gt; = .029) and patients with Military/VA insurance (&lt;i&gt;P&lt;/i&gt; &lt; .001) were significantly more likely to be lost to follow up at their index VQI center at 1 year. When accounting for all standard co-morbidities, none of the following variables had any significant association with the composite adverse perioperative event on multivariable analysis: absolute center volume as an ordinal variable (&lt;i&gt;P&lt;/i&gt; = .985); procedure at a bottom 25&lt;sup&gt;th&lt;/sup&gt; percentile volume center (&lt;i&gt;P&lt;/i&gt; = .214); procedure at a center with less than 10 total fenestrated cases in the database (&lt;i&gt;P&lt;/i&gt; = .521); rural home status (&lt;i&gt;P&lt;/i&gt; = .622); remote from metropolitan home status (&lt;i&gt;P&lt;/i&gt; = .619); highest 10% ADI (&lt;i&gt;P&lt;/i&gt; = .903); highest 20% ADI (&lt;i&gt;P&lt;/i&gt; = .219); Lowest 10% of ADI (&lt;i&gt;P&lt;/i&gt; = .397).

Two years later, the patient presented again with restenosis. She underwent balloon angioplasty of affected vessels with an IN.PACT Admiral® 6 × 40 drug-coated (Paclitaxel) balloon. The patient presented to her local hospital a week later with severe pruritis and a rash, for which she received a dose of parenteral steroid.

The aim of this paper is to present a 10-year analysis of outcomes in patients undergoing primary repair and selective patch angioplasty in CEA.MethodsA retrospective, single-center study including all consecutive patients undergoing elective CEA at our institution between 2014 and 2023. The Primary outcomes were technical success and 30-day overall survival, ipsilateral ischemic stroke, reintervention, and major adverse cardiac events (MACE) rates. The secondary outcomes were &gt;30-day ipsilateral ischemic stroke, reintervention and primary patency. All outcomes were analyzed in relation to the carotid closure technique (primary closure, patch angioplasty, or eversion). A Generalized Linear Mixed Model (GLMM) was used to assess the association between closure technique and both early and late outcomes. Kaplan-Meier estimates were used to analyze follow-up outcomes depending on the closure technique.ResultsA total of 625 CEA procedures were performed on 577 patients [mean age: 71 ± 9 years; 30.7% female], comprising 87.4% primary repairs, 10.4% patch angioplasty, and 2.2% eversion CEA. Technical success was achieved in (n = 615, 98.4%) of the procedures, with no significant difference between repair types (&lt;i&gt;P&lt;/i&gt; value .947). The mean follow-up duration was 60 ± 38.45 months. Early (&lt;30-day) ipsilateral stroke and reintervention did not differ significantly across carotid repair groups. GLMM analysis showed that congestive heart failure (CHF) was a significant predictor of increased risk for stroke and MACE (OR: 8.870, CI 95% 2.046-38.451, &lt;i&gt;P&lt;/i&gt; = .005) (OR: 7.037, CI 95% 1.902-26.038, &lt;i&gt;P&lt;/i&gt; = .005), respectively. Regional anesthesia significantly lowered the risks of stroke (OR: 0.216, CI 95% .065-.721, &lt;i&gt;P&lt;/i&gt; = .014) and MACE (OR: 0.380, CI 95% .158-.914, &lt;i&gt;P&lt;/i&gt; = .032). Long-term (&gt;30-day) ipsilateral stroke and 2-year primary patency were comparable across the groups. GLMM analysis of &gt;30-day stroke revealed no statistically significant differences between patch and primary CEA (OR: 1.947, 95% CI: .321-11.819, &lt;i&gt;P&lt;/i&gt; = .363). Neither age &gt;80 years (&lt;i&gt;n&lt;/i&gt; = 94, 15%) nor female sex (&lt;i&gt;n&lt;/i&gt; = 177, 30.7%) were significantly associated with increased stroke risk (age: OR 0.524, 95% CI: 0.021-7.013, &lt;i&gt;P&lt;/i&gt; = .415; sex: OR 0.524, 95% CI: 0.087-3.152, &lt;i&gt;P&lt;/i&gt; = .370). The analysis of 2-year patency outcomes revealed no significant associations between patch vs primary CEA, sex, or age greater than 80 years.
