BACKGROUND: The necessity of sternal precautions for patients following cardiac surgery with median sternotomy has been questioned by clinicians, researchers, and even patients. The primary purpose was to determine if sternal skin deformation during shoulder movements and upper extremity activities is compressive or distractive and if there are any significant differences between the skin deformation at different positions during shoulder movements and upper extremity activities. The secondary purpose was to determine if sternal skin deformation is correlated with scapular stabilizer muscle strength...

BACKROUND: Coronary bypass surgery using the internal mammary artery (IMA) is among the most commonly performed procedures in treatment of advanced coronary vessel disease. Further, bilateral harvesting of the IMA is associated with increased rates of sternal wound infections. OBJECTIVE: This study aimed to explore changes in sternal perfusion, following left internal mammary artery (LIMA) harvesting. METHODS: 60 patients were divided equally into intervention- and control cohorts and underwent assessment of oxygen saturation (sO2) and relative blood flow (RBF) by laser doppler flowmetry remission spectroscopy preoperatively, 24 h and 72 h postoperatively...

The accurate evaluation of sternal lymph nodes (StLNs) is critical for the staging of canine thoraco-abdominal tumours. Computed tomography (CT) provides a non-invasive means of assessing StLNs, but its diagnostic accuracy for identifying metastases is unclear. In this retrospective cross-sectional study, we assessed the diagnostic power of various CT measurements. Fifty-seven dogs that underwent concurrent CT and cytological examination of the StLNs were enrolled retrospectively. The size, shape, X-ray attenuation and uniformity of the StLNs were assessed...

BACKGROUND: Flexion and compression forces to the trunk can cause severe instability of the vertebral column and the anterior chest wall, mostly associated with an unstable fracture of the sternum. In combination, the worst case would be a complete disruption of the trunk. Some authors consider the sternum-rib-complex to be the fourth vertebral column. This study discusses the possibilities to treat instable trunk injuries with sternal fractures concomitant to vertebral spine fractures through anterior sternal plating employing a locked plate osteosynthesis in a low profile design instead of the use of bulky implants...

BACKGROUND: Esophageal substitutes need conveyance from the abdomen into the neck for restoration of alimentary continuity. Reports suggest that the use of plastic camera sleeve may prove advantageous in restoring conveyance. This study aims to evaluate the practicability of this approach, specifically, in laparoscopy-assisted surgeries. METHODS: The efficacy of camera sleeve in conduit transposition was prospectively evaluated over 2 years. The following parameters were assessed: success/failure; time taken; blood loss; adequacy of length of the conduit delivered into the neck; conduit orientation; ease of procedure through different routes; conduit damage; complications; and drawbacks...

Accurate knowledge of surface anatomy is fundamental to safe clinical practice. A paucity of evidence in the literature regarding thoracic surface anatomy in children was identified. The associations between surface landmarks and internal structures were meticulously analyzed by reviewing high quality computed tomography (CT) images of 77 children aged from four days to 12 years. The results confirmed that the sternal angle is an accurate surface landmark for the azygos-superior vena cava junction in a plane through to the level of upper T4 from birth to age four, and to lower T4 in older children...

Within the Brachyura there are a variety of specialized holding mechanisms, which facilitate the close attachment of the highly reduced pleon underneath the cephalothorax. The most common mechanism in eubrachyurans, known as the press-button, consists of a sternal protrusion and a corresponding pleonal socket. Reports on the microstructural properties of the surface of these holding structures are scarce and patchy. In this study, the European Green Crab Carcinus maenas, is used as model to describe the microstructure of a typical press-button mechanism with the use of scanning electron microscopy and light microscopic histology...

We investigate the state of sedimentological environment and contaminant status of Repparfjorden (N Norway) impacted by submarine disposal of mine tailings during the 1970s using sedimentological and geochemical properties of seventeen sediment cores. The impact of tailings disposal is mainly restricted to the inner fjord where the discharge occurred. Sediment cores retrieved from the inner fjord contain layers of mine tailings up to 9-cm thick, 3-9cm below the seafloor. Spreading of the tailing-related metal Cu and particles is limited to the inner fjord and to a 2cm layer in one core from the outer fjord...

BACKGROUND: To minimize cardiac perforation during the minimally invasive repair of pectus excavatum (MIRPE), several surgeons have suggested using a suction device to intraoperatively lift the sternum. Whether or not this technique is effective for all PE patients is not yet known. As such, our aim was to quantify the extent to which a suction device is capable of lifting the sternum with a short duration of use. METHODS: 30 PE patients received a low-dose CT scan as part of standard PE evaluation...

Sternal cleft (SC) is a rare form of chest wall deformity with an incidence of <0.15%. It occurs because of failure of fusion of the sternal bars about the 7-9th week of intrauterine life. It could occur in isolation or as a part of a syndromic complex. This condition exposes the vital mediastinal structures to a huge risk of injury, aside from cosmetic issues. Treatment in the neonatal period is most favourable, though other modalities are available in the later stages of life, but it can be challenging...

OBJECTIVES: In cardiac surgery, postoperative bleeding remains a frequent complication with various possible adverse outcomes. Re-exploration due to bleeding is frequent in this type of patient. Sternal wound infection is an infrequent but serious and devastating complication. Whether re-exploration due to bleeding significantly affects the incidence of sternal wound infection is uncertain. There is no consensus on allowed severity of bleeding and timing of intervention. METHODS: A retrospective, observational cohort study of 15 350 consecutive patients who underwent cardiac surgical procedures from 1 April 2006 through 31 December 2013 in 3 different university hospitals in Denmark was performed...

Secondary graft-oesophageal fistula is a fatal complication of aortic arch replacement. We report a successful two-stage surgical management of a graft-oesophageal fistula seen in a 68-year-old woman 3 years after total aortic arch replacement. She presented with a prolonged intractable fever without haematemesis. The fistula occurred between the distal aortic anastomosis and oesophagus; the entire graft was surrounded by air. In the first-stage operation, we performed re-replacement of the entire infected graft, oesophagectomy with cervical oesophagostomy, omental transfer and cervical routing of the stomach roll, through an extended left thoracotomy incision with sternal transection...

Central venoarterial (VA) placement of extracorporeal membrane oxygenation (ECMO) is performed surgically, and in the majority of cases, the patient remains with an open sternum. Herein, a case of a 3-year-old patient who underwent insertion of a central VA ECMO for heart failure due to acute myocarditis is described. An alternative technique for ECMO placement providing sternal closure and minimizing infection risk for the safe patient transport is described.
