The dataset comprised 24 variables, including age, gender, nutritional status, comorbidities, and surgical details. The decision tree classifier was developed and validated using Python 3.7 and the scikit-learn toolkit.ResultsDTA identified poor nutritional status as the most significant predictor, followed by compromised immunity, active cancer, octogenarians, chronic kidney disease, and chronic obstructive pulmonary disease.

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).

Though asymptomatic in many individuals, treatment is often indicated if the AVM causes flank pain, hematuria, or medically refractory hypertension, or if there is an associated renal artery aneurysm. We present a case of a large right renal AVM with associated renal artery aneurysm and large varix which was incidentally found on magnetic resonance imaging of the spine. Endovascular and open surgical options were considered, including ex-vivo renal vascular reconstruction and nephrectomy. The patient was successfully treated with endovascular embolization of the AVM with coil packing of the arterial aneurysm and inflow artery. The patient recovered uneventfully with well-maintained renal function and blood pressure control. We review and discuss the literature on the etiology and treatment options for renal AVM.</p>","PeriodicalId":94265,"journal":{"name":"Vascular and endovascular surgery","volume":" ","pages":"198-203"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142305365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
