Despite technical advancements, access-related vascular complications, occurring in approximately 10% of TAVI procedures, remain a substantial challenge. Objective: This study investigated the clinical and morphological characteristics of percutaneous TF-TAVI patients experiencing occlusive (OC) and hemorrhagic (HC) complications managed with surgical or endovascular reintervention. Methods: The cohort included patients from a Dutch and a German tertiary referral hospital, managed with TF-TAVI procedures between 2017 and 2021 that required reintervention for OC or HC. Demographics, comorbidities, procedural details, and preoperative imaging data were collected and compared between groups. Results: Among 109 TF-TAVI patients, 32 with OC and 77 with HC required reintervention. The OC group presented significantly smaller access arterial diameters (common femoral artery: OC 6.7 mm vs. HC 8.9 mm, p&lt;.001; external iliac artery: OC 7.2 mm vs. HC 8.3 mm, p&lt;.001; common iliac artery: OC 9.4 mm vs. HC 10.5 mm, p=.012) while the HC group presented higher tortuosity index (TI) (OC 1.24 vs. HC 1.30; p=.017). No differences were observed regarding baseline characteristics, vessel calcification or vascular closure device use. Conclusions: In patients requiring reintervention following TF-TAVI, smaller arterial diameters were associated with OC, while higher TI was linked to HC. These findings emphasize the importance of preoperative imaging in developing individualized prevention strategies. <\/jats:p>","DOI":"10.1024\/0301-1526\/a001154","type":"journal-article","created":{"date-parts":[[2024,10,30]],"date-time":"2024-10-30T17:01:20Z","timestamp":1730307680000},"page":"133-141","source":"Crossref","is-referenced-by-count":4,"title":["Comparison of patients with occlusive or hemorrhagic access site complications requiring reintervention after percutaneous transfemoral transcatheter aortic valve implantation"],"prefix":"10.1024","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0601-9223","authenticated-orcid":true,"given":"Moritz","family":"Wegner","sequence":"first","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, Faculty of Medicine and University Hospital Cologne, University of Cologne, Cologne, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-6361-6912","authenticated-orcid":true,"given":"Reinier R.","family":"Smeets","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Maastricht University Medical Center, Maastricht, The Netherlands"},{"name":"Department of Vascular Surgery, Slingeland Ziekenhuis, Doetinchem, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leo F.","family":"Veenstra","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Maastricht University Medical Center, Maastricht, The Netherlands"},{"name":"Department of Cardiology, Zuyderland Medical Center, Heerlen, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5090-3468","authenticated-orcid":true,"given":"Wael","family":"Ahmad","sequence":"additional","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, Faculty of Medicine and University Hospital Cologne, University of Cologne, Cologne, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amelie L.","family":"Behrens","sequence":"additional","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, Faculty of Medicine and University Hospital Cologne, University of Cologne, Cologne, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florian","family":"Kursch","sequence":"additional","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, Faculty of Medicine and University Hospital Cologne, University of Cologne, Cologne, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5810-2868","authenticated-orcid":true,"given":"Hendrik","family":"Wienemann","sequence":"additional","affiliation":[{"name":"Clinic III for Internal Medicine, Faculty of Medicine and University Hospital Cologne, University of Cologne, Cologne, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernhard","family":"Dorweiler","sequence":"additional","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, Faculty of Medicine and University Hospital Cologne, University of Cologne, Cologne, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan","family":"Baldus","sequence":"additional","affiliation":[{"name":"Clinic III for Internal Medicine, Faculty of Medicine and University Hospital Cologne, University of Cologne, Cologne, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6990-8135","authenticated-orcid":true,"given":"Matti","family":"Adam","sequence":"additional","affiliation":[{"name":"Clinic III for Internal Medicine, Faculty of Medicine and University Hospital Cologne, University of Cologne, Cologne, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6545-5813","authenticated-orcid":true,"given":"Barend M.
