Hidroneumotórax producido por la migración de un clavo de Kirschner / Hydropneumothorax caused by migration of a Kirschner wire

Las agujas de fijación tienen un amplio uso en el manejo quirúrgico de fracturas y luxaciones. Infrecuentemente se ha descrito la migración intratorácica de las mismas, que generalmente origina complicaciones graves. Presentamos un caso en el que una aguja de Kirschner, utilizada para la fijación de una luxación posterior de hombro, dio lugar a un neumotórax y a un derrame pleural hemático masivo que presenta especial interés por su curso insidioso, relacionado en parte a las características especiales de la paciente (AU)

Pins and wires have a wide use in the management of fractures and dislocations. Migration of these devices within the chest is rare, but can cause serious complications. We report a case of intrathoracic migration of a Kirschner wire used for the treatment of a posterior shoulder dislocation, causing pneumothorax and massive hemothorax, having an insidious course, probably related to the special characteristics of the patient (AU)

[Postoperative course in 7 cases of primary sarcoma of the lung]. / Evolución posquirúrgica de 7 sarcomas pulmonares primitivos.

Unlike lung metastases of extrapulmonary sarcomas, primary sarcoma of the lung is very rare. We analyzed 7 primary sarcomas treated surgically in Hospital Universitario La Paz, Madrid, Spain between 1985 and 2001. Preoperative histologic diagnosis was correct for 2 patients. Surgery was performed in all 7 patients. Resection was extended to the left atrium in 1 patient, to the chest wall in another, and the parietal pleura were removed from 2 others. Surgical resection was considered complete in 6 cases. Histology revealed 4 cases of malignant fibrous histiocytoma, 1 angiosarcoma, 1 osteogenic sarcoma, and 1 undifferentiated sarcoma. Enlarged lymph nodes removed during surgery were tumor free. Three patients received complementary treatment. The 3 longest-surviving patients were treated with surgery alone; at the end of the study, these patients remained alive 16, 9, and 4 years after surgery. One patient has a recurrent lymph node tumor in a single lung. Three patients died within 1 year and another died 24 months after surgery. In conclusion, surgical treatment of primary sarcoma of the lung can achieve good survival.

Evolución posquirúrgica de 7 sarcomas pulmonares primitivos / Postoperative course in 7 cases of primary sarcoma of the lung

Los sarcomas primitivos pulmonares son muy raros, pero no los metastásicos. Se analizaron 7 sarcomas primarios operados en nuestro servicio entre 1985 y 2001. El diagnóstico histológico preoperatorio fue correcto en 2 pacientes. Se realizó cirugía en todos. En uno se amplió la resección a aurícula izquierda, en otro a pared torácica y en otros 2 se extirpó pleura parietal. Se consideró cirugía completa en 6 casos. En el estudio histológico 4 fueron fibrohistiocitomas malignos, uno angiosarcoma, uno sarcoma osteogénico y uno sarcoma indiferenciado. Las adenopatías extirpadas estaban libres de tumor. Se hizo tratamiento complementario en 3 pacientes. En los 3 de mayor supervivencia se realizó sólo cirugía, con un seguimiento de 16, 9 y 4 años, respectivamente. Uno tiene actualmente una recidiva tumoral nodular en pulmón único. En cuanto a los fallecidos, 3 murieron antes de un año y otro después de 24 meses de evolución. En conclusión, la cirugía en los sarcomas pulmonares primitivos puede conseguir una elevada supervivencia

[Bronchoplasty in bronchopulmonary tumors. Review of 50 cases]. / Broncoplastias en tumores broncopulmonares. Revisión de cincuenta casos.

Bronchoplasty in oncological surgery is performed to remove a tumor while preserving most of the pulmonary parenchyma. Survival in selected patients is similar to survival after lung removal. We report a series of 50 bronchoplastic procedures performed in 37 patients with bronchopulmonary cancer. Twelve had carcinoid tumors and 1 had single lung metastasis from adenocarcinoma of the colon. Twenty-seven operations were performed on the right side and 23 on the left. The pulmonary parenchyma was not resected in 2 patients. The pulmonary artery was also repaired in 5 patients. Mortality at 30 days was 2% (1 patient) and survival at 5 years was 47% calculated according to the method of Kaplan-Meier. Survival was 37 months in only 1 of the 8 patients with mediastinal adenopathy, for whom complementary radiation therapy was provided. Survival among the patients with carcinoid tumors is 91.6% to date, as all but 1 are alive at present. The single death was due to intestinal diverticulosis. The patient with metastasis is alive 12 years after surgery. Spirometric function tests were performed in 17 patients 1 year after surgery and ventilation perfusion was studied in 13. A slight loss of forced vital capacity and maximum expiratory volume in 1 second, while ventilation perfusion corresponding to the parenchyma preserved was normal. Bronchoplasty is the treatment of choice for endobronchial tumors with low degrees of malignancy. Bronchoplasty is an effective surgical treatment for a select group of carcinomas.
