Recently, minimally invasive procedures, such as minimally invasive cardiac surgery, robot surgery, and catheter therapy have been developed in cardiovascular surgery. However, all these surgeries cannot be performed by minimally invasive approaches. Several complications associated with median sternotomy have been reported, although post-sternotomy hemorrhage from the posterior intercostal artery is extremely rare.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Case presentation<\/jats:title>\n                <jats:p>We present a case of posterior intercostal artery bleeding following lower partial sternotomy. A 79-year-old man underwent aortic valve replacement using lower partial median inverted L-shaped sternotomy that cut into the right second intercostal space. A postoperative chest radiograph indicated a hematoma in the right upper chest wall and pleural effusion. Hence, we inserted a drainage tube immediately. Approximately 2\u00a0hours after the surgery, his blood pressure gradually decreased. Blood drainage was observed from the tube, and the amount of blood drainage was not large. Contrast-enhanced computed tomography revealed a huge hematoma and hemorrhage from the fourth right posterior intercostal artery. Immediately, we performed emergency surgery. The lower partial sternotomy was repeated. We detected the origin of the bleeding that was identified in the right fourth posterior intercostal artery, and the bleeding was stopped. The postoperative course was uneventful.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>This case highlights the possibility of intraoperative bleeding from the intercostal artery, even in the absence of clearly rib fracture. In our case, we did not identify the cause of bleeding, although we suggest the inhomogeneous stress on the posterior ribs upon attaching the sternal retractor for lower partial sternotomy may have affected the posterior intercostal artery.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s13019-021-01718-1","type":"journal-article","created":{"date-parts":[[2021,11,21]],"date-time":"2021-11-21T22:02:26Z","timestamp":1637532146000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Massive hemorrhage from the posterior intercostal artery following lower partial sternotomy"],"prefix":"10.1186","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6868-0095","authenticated-orcid":false,"given":"Masashi","family":"Hattori","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Matsumura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fumitaka","family":"Yamaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,11,21]]},"reference":[{"key":"1718_CR1","doi-asserted-by":"publisher","first-page":"1146","DOI":"10.1016\/S1010-7940(97)01210-4","volume":"11","author":"E St\u00e5hle","year":"1997","unstructured":"St\u00e5hle E, Tammelin A, Bergstr\u00f6m R, Hambreus A, Nystr\u00f6m SO, Hansson HE.
