Aortic clamping can be highly risky and endovascular approach can be unsuccessful. We report our experience describing three cases of chronic mesenteric ischemia. In all three cases the preoperative computed tomography angiography revealed an ostial occlusion of the celiac trunk and of the superior mesenteric artery (SMA), a coral reef abdominal aorta, and severe calcification of the iliac arteries. An antegrade aorto-mesenteric bypass using a hybrid clampless anastomosis on the supraceliac aorta was performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The procedures were performed via laparotomy. We carried out the exposure of the anterior supraceliac aorta limited to the zone without major calcifications; then we performed a side-to-end media-adventitial anastomosis between the supraceliac aorta and a Dacron graft 7\u00a0mm without any arteriotomy or clamping. The proximal graft and the aortic anastomosis site were punctured using a 18 G needle. An introducer was then positioned over a wire through the prosthetic graft and pushed into the aorta. Balloon expandable covered stenting to open and stabilize the anastomosis site was performed. Finally, the graft was tunneled to the SMA, and an end-to-side anastomosis was performed. The postoperative courses were uneventful, and the patients were promptly discharged. The follow-up, which in the first case is 4 years, showed the complete patency of the graft in each of the cases treated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The hybrid clampless anastomosis appears to be safe and useful in cases of severe aortic calcification.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15385744231215566","type":"journal-article","created":{"date-parts":[[2023,11,17]],"date-time":"2023-11-17T05:08:31Z","timestamp":1700197711000},"page":"419-425","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Hybrid Clampless Anastomosis in Antegrade Aorto-Superior Mesenteric Artery Bypass"],"prefix":"10.1177","volume":"58","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4519-506X","authenticated-orcid":false,"given":"Elisabetta","family":"Tanda","sequence":"first","affiliation":[{"name":"Unit of Vascular Surgery, \u201cCliniche San Pietro\u201d Hospital, AOU Sassari, Sassari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sara","family":"Zappadu","sequence":"additional","affiliation":[{"name":"Unit of Vascular Surgery, \u201cCliniche San Pietro\u201d Hospital, AOU Sassari, Sassari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriele","family":"De Donno","sequence":"additional","affiliation":[{"name":"Unit of Vascular Surgery, \u201cCliniche San Pietro\u201d Hospital, AOU Sassari, Sassari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Salvatora","family":"Dettori","sequence":"additional","affiliation":[{"name":"Unit of Vascular Surgery, \u201cCliniche San Pietro\u201d Hospital, AOU Sassari, Sassari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandro","family":"Ciccarello","sequence":"additional","affiliation":[{"name":"Unit of Vascular Surgery, \u201cCliniche San Pietro\u201d Hospital, AOU Sassari, Sassari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Franco","family":"Piredda","sequence":"additional","affiliation":[{"name":"Unit of Vascular Surgery, \u201cCliniche San Pietro\u201d Hospital, AOU Sassari, Sassari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gian Franco","family":"Fadda","sequence":"additional","affiliation":[{"name":"Unit of Vascular Surgery, \u201cCliniche San Pietro\u201d Hospital, AOU Sassari, Sassari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,11,17]]},"reference":[{"key":"e_1_3_4_2_2","first-page":"603","volume-title":"Vascular and Endovascular Surgery: A Comprehensive Review","author":"Schwartz LB","year":"2006","unstructured":"Schwartz LB, McKindey JF, Funaki B, Gewertz BL.
