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 results of 25 funnel chest operations are reported. All patients have been treated by a modified Ravitch method. Fixation of the anterior chest wall was achieved by inserting two metal wires. Cosmetic and functional results were critically examined postoperatively. For clinical assessment the cardiorespiratory and ergometric tests were analysed. Cosmetic results were graded by the classification of Hecker. All patients showed a very good cosmetic result. The functional situation could be improved only partially.
The findings of fine needle aspiration (FNA) cytology, immunocytochemical staining and electron microscopy (EM) in a case of malignant peripheral neuroectodermal tumor (PNET) presenting as a soft tissue mass in the lateral abdominal wall are reported. The immediate evaluation of the aspirate revealed cells of a small round cell malignant tumor. To provide a specific preoperative diagnosis, additional cytologic material was aspirated for immunocytochemical and ultrastructural investigations. While the results of EM were nonspecific, allowing only the exclusion of other small round cell malignancies, immunocytochemical staining of the aspirate was suggestive of a PNET. The diagnosis of PNET was corroborated by histopathologic and immunohistochemical findings. This case indicates that an exact preoperative categorization of small round cell malignant tumors can be made by FNA biopsy in otherwise equivocal cases when immunocytochemical and ultrastructural techniques are also utilized.
