As the population ages and the prevalence of obesity increases, cardiac surgeons will be challenged to consider obese patient physiology and body habitus, surgical exposure and sternotomy closure techniques, and postoperative medical management to ensure optimal outcomes. In this article, we describe techniques to improve operative exposure in both obese and non-obese patients undergoing basic cardiac surgery and highlight the roles of surgical team members to ensure patient safety and provide optimal anesthetic management. We describe pre-operative techniques regarding incision-site marking and alternative positioning techniques on the operating table to improve visualization and decrease risk of upper extremity injury. We summarized the roles of surgical team members regarding patient positioning, especially in those that are obese, and the challenges associated for anesthesia staff pre- and intraoperatively. Procedural techniques regarding sternotomy management and closure, cannulation, internal mammary harvest, and mitral valve exposure are discussed. Cardiac surgical teams must consider the risks associated with the obese patient population undergoing cardiac surgery procedures and employ techniques pre-, intra-, and postoperatively in a multidisciplinary fashion. Safe and efficacious techniques are paramount to optimal patient outcomes.</p>","PeriodicalId":17587,"journal":{"name":"Journal of visualized surgery","volume":"4 ","pages":"80"},"PeriodicalIF":0.0,"publicationDate":"2018-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.21037/jovs.2018.03.19","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36115650","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}

Starting from our recent series of TAAAD patients we carried out a retrospective analysis, regarding the failure of primary exclusion at the time of the initial operation. We classified the location of the principal entry tears perfusing the residual false channel. The proposed technique represents our attempt to correct the mechanism of false channel perfusion during primary repair. We describe a new technique designed to address some limitations of standard hemiarch aortic replacement. Its goal are: (I) to reinforce the intimal layer at the arch level; (II) to eliminate inter-luminal communications at the arch level using suture lines around the arch vessels; (III) to provide an elephant trunk configuration for further interventions.</p><p><strong>Methods: </strong>Between August 2016 and January 2018, 11 patients underwent emergency surgery using this technique; 7 were men; the median age was 74 years. All patients were treated using systemic circulatory arrest under moderate hypothermia (26 °C) and selective cerebral perfusion. All patients had supra-coronary repair; 1 patient had aortic valve replacement + CABG. In the first two patients a manual suture around supra-aortic trunks was used; the subsequent seven patients were treated with a mechanical suture bladeless device.

Median cardiopulmonary bypass time was 130 min (IQR, 110-141 min); median arrest time for re-layering was 17 min (IQR, 16-20 min); median total arrest was 36 min (IQR, 29-39 min). Distal aortic anastomosis was performed in zone 0 in 4 patients, zone 1, with innominate replacement, in 5 patients, in zone 2, with branches to innominate and left common carotid arteries, in 2 patients. Median follow up (closing date 06/01/2018) was 443 days (IQR, 262-557 days); no late deaths occurred. No dehiscence at the level of stapler or manual sutures was observed.
