RESUMO
Objective To summarize the clinical experiences of video-mediastinoscopy followed by stenting procedure in treating the superior vena cava syndrome (SVCS),and to investigate their application significant.Methods Nine patients with SVCS without clear histologic diagnosis before procedure were reviewed retrospectively,who were admitted into hospital from November 2007 to October 2013.All of 9 patients were received video-mediastinoscopy and they did not performed pathological check.They were placed the endovascular stent.Results Video-mediastinoscopy followed by stenting procedure 6 cases,parasternal TN mediastinoscopy 2 cases,joint neck and parasternal TV mediastinoscopy 1 case.Nine cases have received a clear pathological diagnosis.There was no death case in-hospital.The operative complication was hemorrhage of 1 case.The cubital venous pressures were (18.6±5.1) cmH2O at stending,(13.5±3.3) cmH2O,(11.3±2.5) cmH2O,(10.3± 2.0) cmH2O at 24,48,72 h after stending,and down to the normal at 72 h (F =67.245,P ＜0.01).The clinical symptoms were obviously relieved.All of them were remained free from SVCS during the follow-up.Conclusion The hybrid procedure of video-mediastinoscopy followed by stenting placement is a highly effective and safe treatment.It can accurately provide informations on diagnosis and treatment.
RESUMO
Introducción: El tratamiento moderno del hemotórax traumático coagulado implica su evacuación temprana y el uso de técnicas mínimamente invasivas. El objetivo de este trabajo es evaluar el resultado de la toracoscopía rígida o sin video en la evacuación del hemotórax coagulado traumático. Material y métodos: Estudio descriptivo, prospectivo de 15 enfermos, 13 hombres y 2 mujeres con edad promedio de 25.5 años en los que se realizó evacuación de hemotórax traumático coagulado de siete o menos días de evolución mediante toracoscopía rígida con mediastinoscopio de Carlens. La operación se llevó a cabo por una o dos incisiones de 2.5 cm. En ninguno se utilizó intubación endotraqueal de doble luz. Resultados: La etiología fue de heridas por arma blanca en 9, proyectil de arma de fuego en 5 y en 1 por trauma cerrado. Además del hemotórax coagulado se encontraron perforación del diafragma en 3, laceración hepática en 1, y laceración pulmonar en otro. Se realizó incisión accesoria en 4 y una fue convertida a toracotomía limitada por dificultad técnica. El tiempo quirúrgico promedio fue de 53.3 min. No hubo mortalidad y la morbilidad fue 1 caso de neumonía (6.6%). El promedio de estancia posoperatoría fue de 3.8 días. El costo estimado fue de 528 dólares americanos. Conclusiones: La toracoscopía rígida con mediastinoscopio de Carlens es un excelente método para evacuar el hemotórax traumático coagulado, con las ventajas de simplicidad en el equipo, menor costo y no necesitar intubación endotraqueal de doble luz. El procedimiento debe ser considerado en el manejo del hemotórax coagulado traumático de siete días o menos de evolución.
Introduction: Modern treatment of clotted traumatic hemothorax involves early evacuation and the use of minimally invasive techniques. The objective of this paper is to evaluate the results of rigid non-video thoracoscopy in the management of clotted traumatic hemothorax. Material and methods: In this prospective work, 15 consecutive patients, 13 men and 2 women, average age 25.5 years, were submitted to evacuation of a clotted traumatic hemothorax within 7 days or less of injury by means of rigid non-video thoracoscopy with a Carlens mediastinoscope through 1 or 2 one inch incisions under general anesthesia using a single lumen endotracheal tube. Results: Etiology were stab wounds in 9, gunshot wounds in 5 and blunt trauma in 1. Associated findings were diaphragmatic perforations in 3, hepatic laceration in 1 and pulmonary laceration in 1. An accessory incision was necessary in 4 cases, and 1 patient was converted to a limited thoracotomy due to technical difficulties. Average surgical time was 53.3 min. There was no mortality; one patient developed pneumoniae (6.6%). Average post-operative stay was 3.8 days. Estimated cost was 528 US dlls. Conclusions: Rigid non-video thoracoscopy using a Carlens mediastinoscope is an excellent method for the evacuation of clotted traumatic hemothorax with the advantages of simplicity of the equipment, diminished costs and the avoidance of double lumen endotracheal intubation. Rigid thoracoscopy should be considered in the management of short term, seven days or less, clotted traumatic hemothorax.
RESUMO
Objective To explore the value of left parasternal anterior mediastinaotomy (Chamberlain procedure) in the diagnosis of mediastinal lymph node enlargement with unknown causes and anterior mediastinal space-taking lesions. Methods By using the Chamberlain procedure, biopsy was performed in 32 cases of enlarged mediastinal lymph nodes with unknown causes or mediastinal space-taking lesions, which were found by CT scans. Results All of the 32 cases were pathologically diagnosed, with a diagnostic accuracy of 100%. Three patients with pericardial effusion received concurrent pericardial fenestration and then their symptoms relieved. Four patients underwent concurrent lung biopsy. The operating time was (48?15) min, the blood lose was ( 40.6?23.5) ml, and the postoperative hospital stay (3.6?1.4) days. No deaths or postoperative complications occurred. Conclusions Chamberlain procedure is a safe and valuable method in the diagnosis of mediastinal space-taking lesions with unknown causes or enlargement of the fifth and sixth groups of mediastinal lymph nodes, which routine mediastinoscope cannot reach. Some other simple therapies, such as lung biopsy or pericardial fenestration, can also be employed at the same time.
