Mesenteric malperfusion was identified in 8 of 49 patients (20%) with malperfusion syndrome. Femoral arterial perfusion was initiated to restore true lumen flow, and intraoperative TEE was used to assess abdominal aortic true lumen expansion and superior mesenteric artery (SMA) perfusion. Central aortic repair was performed after confirmation of mesenteric reperfusion.Results: Dynamic and static mesenteric obstructions were present in 5 and 3 patients, respectively. Femoral perfusion improved SMA flow in all dynamic cases and in 2 static cases. Seven patients (87.5%) survived to discharge; 1 patient with preoperative coma, shock, and static SMA obstruction died. In 1 patient with combined SMA and celiac artery obstruction, residual celiac malperfusion was not detected intraoperatively.Conclusions: Femoral arterial perfusion guided by intraoperative TEE is a feasible and effective strategy for mesenteric malperfusion in ATAAD. However, static branch obstruction and limitations of TEE warrant consideration of hybrid approaches.","PeriodicalId":7995,"journal":{"name":"Annals of vascular diseases","volume":"19 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13082909/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147697226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All patients presented with acute abdominal pain, and some experienced vomiting. Thirteen patients received conservative treatment, while only 1 patient underwent open surgery with extra-anatomical bypass; this patient required no further intervention 10 years postoperatively. One of the patients, whose abdominal pain worsened with food intake, showed SMA stenosis and decreased intestinal blood flow. His symptoms improved after heparin anticoagulation therapy followed by direct oral anticoagulant therapy. Over a follow-up period of 7.20 ± 3.21 years, none of the patients experienced recurrent SIDSMA-related abdominal pain, and all survived without the need for additional invasive treatment.Conclusions: Conservative treatment effectively manages SIDSMA over the long term without reintervention. Early diagnosis and management of intestinal ischemia are essential for optimal treatment outcomes.","PeriodicalId":7995,"journal":{"name":"Annals of vascular diseases","volume":"19 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12921437/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147269602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This pilot, hypothesis-generating study aimed to explore the spatial balance between blood microvessels and lymphatic vessels in human carotid plaques.Methods: Carotid plaques from 4 patients who underwent carotid endarterectomy were examined histologically. Blood microvessels (CD31+) and lymphatic vessels (Podoplanin+) were quantified in severely and mildly thickened lesions. The blood microvessel-to-lymphatic vessel (BMV/LV) ratio was compared between regions, along with macrophage polarization (CD80+: M1 and CD163+: M2).Results: Severely thickened lesions exhibited a 15.5-fold higher density of blood microvessels than mildly thickened lesions (median 31 vs. 2 vessels; p = 0.012), whereas lymphatic vessel counts were comparable (median 31 vs. 32 vessels; p = 0.978). Consequently, the BMV/LV ratio was 16-fold higher in severely thickened lesions (1.203 vs. 0.121, p = 0.060). CD80-positive areas were larger in severely thickened lesions (0.395% vs. 0.078% area, p = 0.006), whereas CD163-positive areas were comparable between regions (1.036% vs. 0.215%, p = 0.154).Conclusions: Mildly thickened carotid atherosclerotic plaques demonstrated relative lymphatic predominance, whereas severely thickened lesions showed angiogenic predominance accompanied by increased M1 macrophage infiltration. These exploratory findings suggest that regional imbalance between lymphatic vessels and blood microvessels within individual plaques may contribute to localized plaque vulnerability.","PeriodicalId":7995,"journal":{"name":"Annals of vascular diseases","volume":"19 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13051298/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147632261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review proposes a conceptual distinction between predictive ML and exploratory ML. Predictive ML aims to maximize accuracy on unseen data. Exploratory ML focuses on identifying underlying structures in data to generate hypotheses. Exploratory ML plays an important role under conditions where conventional hypothesis-driven statistics have limitations, including high-dimensional data, small sample sizes, and biopsy-inaccessible organs such as the vascular system. Because ML-derived results are based on associations rather than causality, they should be interpreted as hypothesis-generating rather than confirmatory. Methods including unsupervised learning, interpretable supervised learning, and network analysis are discussed as exploratory ML approaches. The differences in objectives and evaluation criteria between exploratory ML and conventional hypothesis-driven statistics are also discussed, together with the structural gap in peer review. The key argument is that studies using exploratory ML should be evaluated not by predictive performance but by the stability, reproducibility, and interpretability of the identified structures. Without this shift, exploratory analyses may be systematically misjudged within current evaluation standards. This perspective may bridge exploratory analysis and confirmatory research and support new study designs in medicine.","PeriodicalId":7995,"journal":{"name":"Annals of vascular diseases","volume":"19 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13279870/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148293364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
