OBJECTIVES: Prerequisites for successful trachea transplantation include the use of a biocompatible construct, submucosal vascularization and an epithelial covering. Implantation of non-epithelialized tracheal scaffolds may lead to stenosis. However, epithelial grafting or seeding can only be attempted onto a well-vascularized submucosal bed. Our aim was to investigate a method to prevent stenosis during prelamination of non-epithelialized, gently decellularized rabbit tracheae and to evaluate whether grafting of revascularized constructs with buccal mucosa is feasible...

Prior to the 1970s, pediatric coronary artery bypass surgery (PCABS) was seldomly performed due to the lack of compelling surgical indications. The advent of coronary sequelae secondary to Kawasaki disease (KD) and the occurrence of coronary artery complications due to newly developed procedures, such as the arterial switch operation and early repair for intrinsic congenital coronary malformations, necessitated the development of PCABS. Because children grow rapidly and their life expectancy is very long, with increasing exercise capability requirements, the strategy for PCABS should differ from that for bypass surgery in adults...

BACKGROUND: Observational studies suggest a survival advantage with bilateral single internal thoracic artery (BITA) versus single internal thoracic artery grafting for coronary surgery, whereas this conclusion is not supported by randomized trials. We hypothesized that this inconsistency is attributed to unmeasured confounders intrinsic to observational studies. To test our hypothesis, we performed a meta-analysis of the observational literature comparing BITA and single internal thoracic artery, deriving incident rate ratio for mortality at end of follow-up and at 1 year...

The internal thoracic artery (ITA) is the largest thoracic wall artery and is clinically important primarily for use in coronary artery bypass grafting. A number of anatomic variants of the ITA have been reported; however, bilateral, aberrant lateral branches of the ITA never have. The importance of this finding lies in the positioning of the artery at a potential chest tube insertion site. Here, we report the identification, on CT scan, of this rare variation in a young male trauma patient.

BACKGROUND: The resuscitative endovascular balloon occlusion of the aorta, because of its efficacy and feasibility, has been widely used in treating patients with severe torso trauma. However, complications developing around the site proximal to the occlusion by resuscitative endovascular balloon occlusion of the aorta have almost never been studied. CASE PRESENTATION: A 50-year-old Japanese woman fell from a height of approximately 10 m. At initial arrival, her respiratory rate was 24 breaths/minute, her blood oxygen saturation was 95% under 10 L/minute oxygenation, her pulse rate was 90 beats per minute, and her blood pressure was 180/120 mmHg...

We herein present the unique case of a 68-year-old male diabetic patient who developed sterile necrosis of the sternum 1 month after myocardial revascularization with the use of bilateral internal thoracic artery grafts. The sternum had been closed by the bilateral Robicsek wiring technique. The sternum was removed, and bilateral pectoralis major flaps were used to cover the defect. The patient had an uneventful recovery.

In Kawasaki disease (KD), giant coronary aneurysms in the proximal segments of the coronary arteries have long been among the serious complications associated with acute myocardial infarction. To treat myocardial ischemia in children, Kitamura et al. first performed coronary artery bypass grafting in a pediatric patient using an autologous saphenous vein. In the early 1980s, they began to use the internal thoracic artery (ITA) as a bypass graft to the left anterior descending artery, which later was proven to improve long-term life expectancy with its favorable long-term patency, as well as growth potential...

Recent evidence shows that multi-arterial coronary artery bypass grafting (MABG) based on bilateral internal thoracic (BITA) or left internal thoracic (LITA) and radial artery (RA) improves long-term outcomes compared with single arterial coronary artery bypass grafting (SABG) (LITA + saphenous vein graft). How this evidence affected the worldwide use of MABG, if at all, is not well defined. Accordingly, we report 10-year temporal trends of MABG utilization from 2 continents. A study population of 1,683,434 non-emergent, primary, isolated LITA-based coronary artery bypass grafting (CABG) (≥2 grafts) patients was derived from the Society of Thoracic Surgeons (STS) (1,307,528 (79...

OBJECTIVES: Bilateral internal thoracic artery (BITA) grafting strategy is the current trend in coronary artery bypass grafting for multivessel coronary artery disease. Although better long-term outcomes have been shown, BITA grafting is underutilized as a main strategy for revascularization by most of the surgeons. The survey was conducted to ascertain the current usage and concerns of BITA grafting in India. METHODS: Database of 856 Indian cardiac surgeons currently with predominantly adult practice was prepared and a questionnaire was sent about use of single and bilateral ITA grafts and BITA grafting strategy in different clinical scenarios...

Although improved long-term outcomes obtained with the use of arterial grafts for coronary revascularization in comparison with the traditional association of a single arterial and saphenous vein grafts have been demonstrated in the overall population, the efficacy of this newer technique in the elderly is difficult to prove because their shorter life expectancy due to advanced heart disease, associated with severe comorbidities. Moreover, more widespread use of this technique is limited by the concerns on the potential morbidity, particularly the longer time required to perform the operation and the possibility of deep sternal wound infection in case of bilateral internal thoracic artery harvesting due to the decreased blood supply to the sternum and surrounding tissues...

BACKGROUND: There are significant gender differences in arterial revascularization approaches in coronary operations. This study addressed these differences to determine whether discrepancies are related to underlying risk profiles or systematic gender bias. METHODS: Changes in gender-specific rates of revascularization approaches were determined in 19,557 patients undergoing isolated coronary artery bypass grafting (CABG). A propensity-balanced group was generated on a subset of 1,254 CABG patients based on 45 pretreatment covariates to assess rates in matched groups (627 patients per group)...

BACKGROUND: Clinical evidence comparing the surgical risk and long-term effectiveness of the bilateral internal thoracic artery (BITA) and single internal thoracic artery (SITA) for coronary artery bypass grafting (CABG) in hemodialysis patients is limited. We sought to clarify the short-term and midterm outcomes of CABG using BITA or SITA grafts in hemodialysis patients. METHODS: Between October 2000 and December 2015, 161 hemodialysis patients underwent isolated CABG by internal thoracic artery grafting; 67 received BITA grafts and 94 SITA grafts...

The internal thoracic artery skeletonization method typically involves careful dissection with electrocautery. However, skeletonization using harmonic technology is safer than the conventional method. Ultrasonic shears may be faster than traditional methods, and may optimize the quality of skeletonized grafts during harvesting, preserving their functional and structural conduit integrity, and facilitating harvesting of the bilateral internal thoracic artery. This tutorial shows in detail the skeletonization harvest technique, using Ethicon's harmonic shears (Ethicon Endo-Surgery©, CVD, Cincinnati, OH, USA) Our results, using this technique, showed no harvesting damage and excellent graft quality as evaluated intraoperatively...
