Management of a floating sternum after repair of pectus excavatum   总被引:7,自引:0,他引:7  
PURPOSE: The aim of this study was to examine the authors' experience with patients who have floating sternum after correction of pectus excavatum via the classical Ravitch procedure. A floating sternum is defined as a sternum in which the only attachment to the chest wall is its superior (cranial) border, and in which the body is secured only by the manubrium and whatever lateral and inferior fibrous bands are present. Typically, a floating sternum is caused by either extensive resection of the costal cartilages and perichondrium during correction of pectus excavatum or failure of proper regrowth of these cartilages. METHODS: The authors retrospectively assessed the charts of all patients diagnosed with a floating sternum noting age at original correction of pectus excavatum, time from original correction of pectus excavatum to diagnosis of floating sternum, age at correction of floating sternum, complaints before stabilization of the sternum, methods of repair, and postoperative complications. RESULTS: Between July 1993 and June 1999, floating sternum was diagnosed in 7 patients. The mean age of patients who underwent operative correction of a floating sternum was 28.9 years (range, 16 to 42 years). The mean time interval between original correction of pectus excavatum, or "redo," and diagnosis of a floating sternum was 9.9 years (range, 2 to 20 years). Complaints before correction of the floating sternum included sternal pain and instability, exercise intolerance, and difficulty breathing. Operative repair consisted of mobilizing the lateral and inferior edges of the sternum, detaching the fibrous perichondrium, performing anterior sternal osteotomies, and finally supporting the sternum with substernal Adkins struts. All 7 patients had successful stabilization of the sternum. Two of 7 patients underwent 2 procedures to successfully stabilize the sternum. One patient has Adkins struts still in place because of hematopoetic malignancy. Six of 7 patients are now without symptoms. CONCLUSIONS: A floating sternum is a morbid phenomenon that may manifest many years after the original procedure. It can cause significant sternal pain, chest wall instability, and respiratory dysfunction, which are the hallmark indications for correction. Repair of a floating sternum can be accomplished successfully.  相似文献

Injuries to the sternum and thoracic cage are relatively frequent in this age of motor-vehicle accidents, high-speed sports activities, and industrial injuries, yet non-union of a fracture of the sternum is exceptionally rare. Sternotomy is commonly performed in cardiothoracic surgery, and the sternum is usually divided vertically or transversely, but non-union of the sternal cut is rare. Fracture of the sternum in a child is especially rare.  相似文献

The number of redo cardiac operations, especially coronary artery bypass grafting (CABG), has recently been increasing mainly due to the failure of saphenous vein grafts. Re-opening a median sternotomy is troublesome, because of possible adhesion of the heart to the sternum. Preoperative computed tomography is quite useful and helpful in determining the degree of the adhesion of the heart and ascending aorta to the back of the sternum. We report here a safe and useful technique for sternal re-entry using a retractor for harvesting the internal thoracic artery (ITA). When re-opening a median sternotomy the incision is made to the sternal wires; the wires are then cut and removed. Small rake retractors, which are connected to the ITA retractor, are hooked to both ends of the left side of the sternum. The ITA retractor is gently wound up to lift up the sternum. An oscillating saw is then applied to divide the anterior table of the sternum. When the posterior table of the sternum is carefully divided, the left side of the sternum is automatically elevated slightly. Complete division of the sternum can be confirmed by this slight elevation. If the left side of the sternum is elevated a little bit more by the ITA retractor, the dissection of the adhesion between the sternum and the heart can be performed without assistance. This technique is most beneficial for a case of redo CABG with the use of the left ITA, but it can be applied in any patients who previously underwent median sternotomy.  相似文献

Failed regeneration of costal cartilage after open repair of pectus chest wall deformities can result in a floating sternum. A floating sternum can be repaired by insertion of a rib graft between the rib and sternum, and stabilization with a metal strut. The metal implant is usually removed with a second operation. We report use of bioabsorbable struts to stabilize rib grafts during repair of a floating sternum in an 18-year-old male with a failed open repair of pectus carinatum. He had an uncomplicated peri-operative course. One year later, the sternum had a normal appearance and was sturdy. A second operation for removal of hardware was not necessary.  相似文献

Pectus excavatum is the most common chest deformity. Children with severe deformities suffer physical complaints such as frequent respiratory infections and decreased endurance. Patients with even mild deformities may complain of physical and psychological symptoms after puberty. In most patients, cardiac and respiratory function deteriorates, meaning that surgical correction is important for alleviation of symptoms and improving cardiopulmonary function and quality of life. The methods of surgical repair remain controversial. The traditional method, first described by Ravitch, comprises resection of deformed cartilages and correction of the sternum by wedge osteotomy in the upper sternal cortex. Ravitch’s methods have been modified using autologous or exogenous materials to fix the lower sternum. Nuss reported a novel method in which neither an anterior wound nor the cutting of cartilage or sternum is required; instead, a convex metal bar is placed behind the sternum. We have reported sternocostal elevation, in which a section of costal cartilage is resected, and all of the cartilage stumps are resutured to the sternum. The secured ribs pull the sternum bilaterally, such that the resultant force causes the sternum to rise anteriorly. Because most pectus excavatum patients are young and maintain an acceptable quality of life preoperatively, we believe that the morbidity rate is one of the most important factors in selecting the method for corrective surgery. Repair can be performed safely through the use of skilled techniques and a deep understanding of the anatomy and physiology of the thorax.  相似文献

A primary giant cell tumor (GCT) originating from the sternum is extremely rare. We report a case of a GCT originating from the sternum in a 45-year-old man who was referred to us for a mass in the anterior chest wall that had been growing slowly. Computed tomography revealed a soft tissue mass involving a large osteolytic and destructive lesion of the sternum body. Subtotal sternectomy and reconstruction with methylmethacrylate were performed. The tumor was 8.5 x 4.5 x 2.5cm, and the histopathological examination confirmed GCT. Radical wide resection of primary sternum tumors and reconstruction with an appropriately rigid prosthetic material are necessary to minimize local recurrence.  相似文献

A new method is described for stabilizing dehiscence or instability of median sternotomy incisions using stainless steel retention sutures. The method has been used successfully in patients who had disruption of the sternum following open-heart surgery and resulted in no complications. It is recommended also as a preventive measure for closure of the sternum in elderly, debilitated patients with a fragile sternum and with prolonged low cardiac output after operation.  相似文献

The deformity of pectus excavatum is caused by a negative pressure in the anterior mediastinum sucking in the body of the sternum. This is usually due to the heart lying on the left side, leaving the mediastinum empty so that the sternum and costal cartilages are sucked in to fill the empty space. The operation consists of excising the deformed cartilages, mobilizing the sternum, and suturing the pericardial sac into a central position which corrects the deformity.  相似文献

Poly (L-lactide) sternal coaptation pin has been developed as an assistant material for the fixation of sternum. We used the novel material to a patient who underwent median sternotomy. A 21-year-old male was suspected to have invasive thymoma in the anterior mediastinum. The median sternotomy was indicated as an approach for the resection of tumor. Tumor was completely resected and there was no invasion to sternum. For the fixation of sternum, three poly (L-lactide) sternal coaptation pins were inserted in the bone marrow of sternum and five stainless steel wires were used as conventional procedure. Sternum was adapted without slippage and no complication from the material was observed in the post-surgical period. The application of poly (L-lactide) sternal coaptation pin is a good option for ensuring the fixation of sternum.  相似文献
