While the European Society for Vascular Surgery (ESVS) recommends endovascular repair as the first-line treatment, open surgery remains a valuable option when endovascular repair is not feasible due to clinical or technical constraints.MethodA systematic literature review was conducted covering the period from 2010 to 2024. Twenty-five surgically treated SMAA cases were identified. Data were collected on patient characteristics, surgical indications, procedures performed, and clinical outcomes.ResultThe majority of patients were male (80%) with a mean age of 46 years. Indications for open repair included mycotic aneurysm (48%), collagenous disease or fibrodysplasia (20%), emergency repair for hemoperitoneum (4%), and unfavorable anatomy for endovascular treatment (28%). Surgical techniques included simple aneurysmectomy (56%) and aneurysm resection with graft reconstruction (44%). No intra- or postoperative bleeding or major complications were reported. In-hospital mortality was 16%, primarily due to acute bowel ischemia (12%). Among survivors, vascular reconstructions demonstrated 100% patency at a mean follow-up of 14 months (range 1-48 months), with no need for reintervention and no deaths during follow-up.ConclusionOpen surgical repair remains a viable treatment option in cases of infected SMAA, collagenous disease, or complex anatomy unsuitable for endovascular repair. It ensures satisfactory survival, favorable clinical outcomes, and durable mid-term patency without the need for reintervention.</p>","PeriodicalId":23549,"journal":{"name":"Vascular","volume":" ","pages":"17085381251379848"},"PeriodicalIF":0.9,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145056002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the concern about the difficulty in hemostasis after removing the sheath, the patient was immediately transferred to our hospital. In emergency situations, when there were no covered stents of appropriate sizes available, we ultimately opted to physician-modified endograft (PMEG) for endovascular repair.

Long-term outcomes are poorly studied between covered stents (CS) and bare metal stents (BMS) for the SFA.MethodsPatients (2017-2021) undergoing CS and BMS to the SFA were identified at an academic institution. Comparative statistics and Kaplan-Meier analysis were used to evaluate outcomes by group.ResultsOne hundred and nineteen patients undergoing stenting were included with 60 patients undergoing CS (50%) and BMS in 59 (50%). There were no differences in sex (<i>p</i> = 0.5), preoperative ABI (<i>p</i> = 0.2) or indication for surgery between groups (<i>p</i> = 0.8). CS patients had undergone more prior SFA interventions (<i>p</i> = 0.03) and were younger (62 vs. 66 years; <i>p</i> = 0.04). Regarding anatomic and operative characteristics, CS patients had more TASC C/D lesions (69 vs. 47%; <i>p</i> = 0.006) less severe calcification (8 vs.17%; <i>p</i> = 0.0006) and more often underwent angioplasty and stenting (90 vs 51%; <i>p</i> < 0.0001) and less often angioplasty, DCB and stenting (5 vs. 43%; <i>p</i> < 0.0001). CS patients had larger SFA (5.7 vs 4; <i>p</i> < .0001), longer lesions (119 vs. 89 mm; <i>p</i> = 0.0008), higher popliteal runoff score (8.3 vs. 6.4; <i>p</i> = 0.02), longer surgery (140 vs. 118 min; <i>p</i> = 0.03), less fluoroscopy time (21 vs. 26 min; <i>p</i> = 0.03), larger SFA stent (6.2 vs. 5.6 mm; <i>p</i> < 0.0001), and longer stented length (260 vs. 171 mm; <i>p</i> < 0.0001). There were no differences in concomitant iliac/tibial treatment between groups (<i>p</i> = 0.3). Regarding outcomes, there were no differences in amputation (CS 10 vs. BMS 10.2%; <i>p</i> = 1) but overall mortality was lower in CS patients (8 vs 22%; <i>p</i> = 0.04) as was acute limb ischemia (17 vs. 34%; <i>p</i> = 0.03). CS patients underwent fewer endovascular (<i>p</i> = 0.03) and open reinterventions (<i>p</i> = 0.005) but a shorter time to first endovascular reintervention (5.6 vs. 17.8 months; <i>p</i> = 0.0002) on unadjusted analysis. Kaplan-Meier estimated survival at 48 months was 83% for CS and 75% for BMS (<i>p</i> = 0.28). At 36 months, primary patency was 35% for CS vs. 41% for BMS (<i>p</i> = 0.09), primary-assisted patency was 57% for CS vs. 68% for BMS (<i>p</i> = 0.04) and secondary patency for CS was 61% vs. 61% for BMS (<i>p</i> = 0.99).ConclusionsIn this series, CS was associated with lower reintervention rates than BMS despite higher TASC classification, longer lesions, and higher popliteal runoff scores. CS was more often used to salvage previous SFA intervention. At 3 years, however, patency was similar between groups. These data suggest some advantages for CS over BMS in endovascular salvage of failed SFA intervention and potentially a preferred modality for more complex SFA lesions than BMS.</p>","PeriodicalId":23549,"journal":{"name":"Vascular","volume":" ","pages":"17085381251379289"},"PeriodicalIF":0.9,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145041515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One method that can aid in selecting a suitable vein for bypass is simulating the solid-fluid interaction, and performing such simulations requires knowledge of the mechanical properties of bypass grafts. Therefore, extracting the mechanical properties of bypass grafts is essential.MethodsIn this study, human bypass grafts were subjected to uniaxial tensile testing, and their elastic modulus was extracted and compared.
