[Disinsertion of the left innominate vein during median vertical sternotomy (author's transl)].

The left innominate vein may be torn during median vertical sternotomy. This tear may in fact be a disinsertion of the venous trunk from the superior vena cava. Repair of this disinsertion is difficult, with a risk of stenosis. It requires the most careful technique, after dissection of the superior vena cava on either side of the tear. It is made much more simple by the use of extracorporeal circulation, which empties and collapses the superior vena cava. Finally, it may be necessary to repair this loss of substance by enlarging it with a fragment of saphenous vein.

Coverage of the open sternotomy wound with Biobrane dressing.

Massive edema accumulated after prolonged cardiopulmonary bypass for coronary grafting such that neither the sternum nor the presternal skin could be closed after insertion of a left ventricular assist device. To protect the mediastinum from infection, we applied Biobrane synthetic temporary wound dressing and placed a moist gauze dressing over it. When the dressing was removed 4 days later, the wound was pink, granulating, free from infection, and suitable for closure. Use of Biobrane biologic dressing should be considered when the mediastinum must remain exposed after median sternotomy.

Median sternotomy infection. Management and reconstruction.

Median sternotomy infections are a difficult and potentially lethal problem. Three patients are presented who manifested variations of this clinical problem, and techniques to treat this complication are described. Successful management entails maximum debridement, elimination of mediastinal dead space utilizing omental or pectoralis major muscle flaps, adjunctive systemic antibiotics, closed irrigation systems, and reconstruction of chest wall stability.

Creatine kinase and lactate dehydrogenase in the muscles encountered during median sternotomy and in the myocardium of the cardiac chambers.

The validity of using creatine kinase MB and lactate dehydrogenase serum isoenzymes to confirm the diagnosis of perioperative myocardial infarction in patients who have had cardiac operations has been questioned, since both have been detected in skeletal muscles. Little is known concerning the concentration of either isoenzyme in the muscles routinely encountered during median sternotomy. Since we have previously shown that the dog is an adequate model in which to study creatine kinase and lactate dehydrogenase isoenzymes, eight healthy dogs were placed under general anesthesia and 1 gm blocks were resected from selected muscles (intercostals, rectus abdominis, diaphragm, and sternothyroid) and from the walls of all four cardiac chambers. Each 1 gm block was homogenized individually in Ringer's lactate, centrifuged, and the supernatants were analyzed for total creatine kinase and lactate dehydrogenase activity by spectrophotometry. Isoenzymes were determined by agarose gel electrophoresis. The study shows that the chest wall muscles and atrial myocardium have appreciable quantities of creatine kinase MB. Hence, serum creatine kinase MB bands in the perioperative period can be generated by manipulation of chest wall muscles and the atrial wall as well as by infarction of the ventricular myocardium.

Sternotomy infection after harvesting of the internal mammary artery.

Use of the internal mammary artery for coronary revascularization does not increase the incidence of postoperative median sternotomy wound infection. When infection does occur in these patients, however, successful treatment is more likely to require more aggressive surgical manipulation, such as the use of vascularized muscle pedicle grafts, to eventually close the sternal defect.

[A cosmetically advantageous approach to median sternotomy].

A horizontal submammary skin incision was chosen as approach route to median sternotomy in 36 patients undergoing cardiac operations. The low complication rate in conjunction with a cosmetically acceptable result makes this procedure the method of choice for selected patients. The potentially higher risk of infection should not be overlooked when planning the operation.

The orthopedic approach in infected median sternotomy.

A retrospective review of 10 infected median sternotomies revealed that the management may be difficult and several procedures may be required to obtain a satisfactory result. Repeated curettage was successful in four patients. The cavity created by d ebridement was treated by the temporary insertion of gentamicin beads in one patient and by the Papineau bone grafting procedure in two. In two patients the thoracic cage became unstable as a result of extensive d ebridement and was stabilized successfully by inserting Harrington compression rods. One patient died of mediastinitis.

Reconstruction after median sternotomy infection.

Reconstruction after median sternotomy infections is a difficult problem. We have presented ten consecutive patients with a wide variety of underlying cardiac illnesses who have had this dreaded complication develop. All of these patients have undergone successful reconstruction after adequate debridement and elimination of the mediastinal dead space using a combination of well vascularized omentum and pectoralis major muscle flaps. Stability of the chest wall has been accomplished primarily with pectoralis major muscle flaps. Complications have been few, morbidity has been significantly reduced and mortality, thus far, has been eliminated, although we certainly have no expectations that it will remain so.

Aortocoronary bypass procedures and sternotomy infections: a study of antistaphylococcal prophylaxis.

In a prospective study of cephalothin prophylaxis for patients who underwent aortocoronary bypass an unacceptably high rate (44%) of Staphylococcus aureus sternotomy infections occurred in a placebo-treated group. In two other groups of patients, one group given cephalothin intraoperatively and the other given the antibiotic both intra- and postoperatively, such infections occurred with similar frequency (2.6% and 2.1% respectively). This study demonstrates the need for antistaphylococcal agents during aortocoronary bypass operation. No advantage is derived by extending this therapy beyond the operative period.

Avulsion of the innominate vein during median sternotomy.

Two cases of disinsertion of the left innominate vein from the superior vena cava (S.V.C.) during primary median sternotomy have been encountered during the past 6 years. Methods of management consisting of either (1) ligation and division of the left innominate vein and patch angioplasty of the SVC injury, or (2) patch angioplasty of the disinsertion injury itself with preservation of the left innominate vein are presented. The rationale and possible complications of each method of treatment are discussed based on the anatomy and collateral circulation of the left innominate vein and other experiences with division of the left innominate vein.

[X-ray findings of the sternum after sternotomy (author's transl)].

X-ray examination of the sternum after sternotomy supplies proof of rupture of a suture, of dehiscence of the sternum, malpositioning of the wire ligature, of the cutting-through of the fixation wire by the bone, of the fracture, pseudoarthrosis and inflammation. Fractures can be located in the manubrium sterni, the body of the sternum, the xiphoid process and in one of the two parts of the sternum. Pseudoarthroses can be seen in the manubrium, in the body of the sternum or as longitudinal pseudoarthroses. Pseudoarthroses were found only in conjunction with inflammatory chances. Signs pointing to an osteomyelitis of the sternum can be very discreet. This applies to both the reactive scleroses and to osteolyses. In individual cases the examination of a fistula system allows identification of a connection to the bone or to the ligature material. Retrosternal abscesses can be differentiated in the computer tomogram from dissections after bolus injection. Diagnosis by exclusion requires tomography in two planes with complicated blurs. In such cases the diagnostic reliability is probably far superior to the reliability achieved by plain roentgenography and with longitudinal blurring.

Brachial plexus injury following median sternotomy.

Brachial plexus injuries are annoyingly common after median sternotomies and vary from those causing minor symptoms to those producing major disability. We compared two groups of patients operated upon with the arms either abducted to a 90 degree angle or at the sides and found no difference in the incidence of brachial plexus injury. However, the finding of Horner's syndrome in one patient and the finding in another (at autopsy) of brachial plexus penetration by a fractured first rib caused us to question traction on the brachial plexus as the correct pathogenesis of the injury. A concomitant autopsy study demonstrated fractured first ribs penetrating the brachial plexus in 11 of 15 patients whose sternum was opened with the sternal retractor placed in the usual location, but in none in 15 patients whose sternum was opened with the retractor displaced two intercostal spaces caudally. The injury can be minimized by opening the sternal retractor as little as is necessary and by placing it as caudally as possible commensurate with adequate exposure.

[Tactics and technique of primary correction of aortic arch interruption using a median sternotomy].

Primary correction of an interrupted aortic arch was performed in seven neonates aged 2 to 26 days. The operation was performed from median sternotomy with extracorporeal circulation using hypothermic arrest of the circulation for reconstruction of the aortic arch. In all neonates it proved possible to make a direct anastomosis of the ascendent and descendent aorta. At the same time in six children a defect of the ventricular septum was closed, in two the common arterial trunk was corrected, in one resection of subaortic stenosis was performed and in another child correction of the aortopulmonary window. After the operation three neonates died from sepsis and multiorgan failure. At present four patients are alive who, 10 to 20 months after operation, are in a good condition. All have a non-restrictive anastomosis of the aorta. Primary correction of an interrupted aortic arch and associated defects is preferred by the authors to two-stage surgery.

[Limited skin incision and partial median sternotomy for the repair of atrial septal defects in children].

Eight patients underwent the repair of atrial septal defect using the limited skin incision and partial median sternotomy. The average length of skin incision was 55% of the longitudinal size of the sternum. Our approach did not prolong the operation time and decreased the bloodloss. Moreover, postoperative events, such as hematoma, sternal instability, and wound infection, were not observed, and the cosmetic result was excellent. We think this method is safe and effective especially for children with atrial septal defect.

[Secondary sternotomy in pediatric heart surgery].

PURPOSE: To analyze the results observed in children who underwent surgical correction of congenital anomalies, in whom the sternotomy was left open to avoid postoperative heart compression. METHODS: Fourteen children with mean age of 11 months, with different kind of congenital malformations who underwent definitive correction were submitted to the technique of delayed sternal closure. The indication was: hemodynamic instability due to sternal approximation (8), uncontrolled bleeding (4) and preventive (2). In all patients a bovine pericardial patch was sutured to the skin edges allowing a good decompression of the heart. RESULTS: Among the 14 children, two died in the immediate postoperative period, before the secondary sternal closure. There were two other deaths in the remaining 12 children who underwent sternal approximation, one due to acute pneumothorax and the other due to low cardiac output. The incision was closed after hemodynamic stabilization was achieved, and happened usually around the 3rd postoperative day. There were no cases of mediastinal infection. CONCLUSION: The technique of delayed sternal closure is an important approach in pediatric cardiac surgery and can be life saving. In our experience a bovine pericardial patch proved to be effective in decompressing the heart and also in protecting the mediastinal cavity.

[The sternotomy and thoracotomy approaches in the treatment of differentiated thyroid cancer in an advanced phase].

The authors report their experience in the treatment of well-differentiated thyroid cancer. The analysis of 5 cases treated with extensive surgery give the opportunity to discuss about the use of sternotomy or thoracotomy to eradicate mediastinal lymph nodes. The importance of preoperative assessment, especially by histological examination is stressed as well as the role of surgery in the multidisciplinary approach for the treatment of the disease.

Mucormycosis of a median sternotomy wound.

Mucormycosis is an unusual complication of cardiothoracic surgery. The fungi may infect the sternotomy wound causing a progressive gangrene or seed the implanted prosthetic valve or graft resulting in endocarditis or graft failure. There have been six previous reports of mucormycosis following cardiothoracic surgical procedures. Four cases involved prosthetic devices, the remaining two are examples of sternal wound mucormycosis acquired from the use of contaminated elasticized bandages. The first case of sternal wound mucormycosis not associated with elasticized bandages is reported here. The infection occurred in a diabetic patient who had undergone coronary artery bypass surgery and mitral valve replacement. The patient received corticosteroids and broad-spectrum antibiotics at the time of and after operation. The patient developed invasive sternal mucormycosis and died on day 10 after surgery, despite aggressive surgical débridement and amphotericin B therapy. No elasticized bandages were used and the source of the infection was not identified. Previous cases of mucormycosis in cardiothoracic surgery are reviewed and the specific clinical setting in which this fungal disease should be suspected defined.
