Introduction: Inhalations, postural drainage and respiratory physiotherapy are not always effective in removing tracheobronchial secretions. Objectives: To evaluate an alternative surgical technique, modified crichothyroidotomy, to aspirate tracheobronchial secretions. Method: Modified crichothyroidotomy is the introduction of a catheter number 8, 10 or 12 into the crichothyroid membrane in order to stimulate coughing and the aspiration of secretions. This is a descriptive study of the benefits as well as immediate and late complications caused by the use of this technique in 45 patients with excessive tracheobronchial secretions inadequately removed by usual methods. Results: Immediate surgical complications were bleeding (10 patients), oropharynx deviation (3), subcutaneous emphysema (1) and difficult introduction (1). Mean catheter permanence was 14 ± 16 days and, in all cases, the catheter provoked coughing and allowed the easy aspiration of secretions. The most frequent occurrence (17 patients) was the expulsion of the catheter by coughing, inadequate catheter handling during aspiration and moving of the patients. Conclusion: This is a simple technique with a low morbidity rate and represents constitutes an effective alternative to be used in the aspiration of tracheobronchial secretions.

Estudo sobre a eficácia da aerostasia pulmonar, em modelo animal, utilizando diferentes tipos de suturas

J Bras Pneumol.2003;29(5):295-301

Abstract PDF PT

Background: The search for an ideal procedure to accomplish aerostasis, after partial surgical resection of the lung parenchyma, remains a practical challenge for the thoracic surgeon. Objective: The objective of this study was to compare the ability of four types of parenchymal pulmonary sutures in preventing air leaks, using a porcine model with incremental endobronchial pressures. Method: Ex vivo experimental study in porcine lungs (n = 5) at the Laboratory of Experimental Surgery of the Universidade de Caxias do Sul. Four different parenchymal pulmonary types of suture were analyzed: type 1 (absorbable suture), type 2: (stapled suture), type 3 (stapled suture with bovine pericardium) and type 4 (stapled suture with biologic glue). The surgical sutures (n = 40) were exposed to different intrabronchial pressure levels, varying from 10 cmH2O to 60 cmH2O. The presence of air leaks along the suture line was verified through the water seal maneuver. Results: The mean intrabronchial pressure level needed to cause suture line air leaks for each type were: type 1 (n = 10): 29 cmH2O; type 2 (n = 10): 38.5 cmH2O; type 3 (n = 10): 44 cmH2O; and type 4 (n = 10): 51.4 cmH2O. The comparison between the mean intrabronchial pressure level of type 1 and of types 2 and 3 sutures was statistically significant, respectively: p = 0.04 and p = 0.01. However, the comparison between types 2, 3 and 4 did not show statistic significance (p > 0.05). Conclusions: The pulmonary suture covered by biologic glue demonstrated more resistance to incremental levels of intrabronchial pressure. Parenchymal pulmonary sutures using stapled suture exclusively or stapled with bovine pericardium or biologic glue demonstrated an increased ability to avoid air leaks if compared to absorbable sutures in a model of porcine lung with incremental levels of intrabronchial pressure. There were no differences between stapler exclusively or stapler and bovine pericardium or biologic glue.

Video-assisted thoracoscopic implantation of a diaphragmatic pacemaker in a child with tetraplegia: indications, technique, and results

Implante de marca-passo diafragmático por videotoracoscopia em criança com tetraplegia: indi-cações, técnica e resultados

Abstract PDF PT PDF EN Portuguese Text

We report the case of a child with tetraplegia after cervical trauma, who subsequently underwent diaphragmatic pacemaker implantation. We reviewed the major indications for diaphragmatic pacing and the types of devices employed. We highlight the unequivocal benefit of diaphragmatic pacing in the social and educational reintegration of individuals with tetraplegia.

Extralobar pulmonary sequestration with hemothorax secondary to pulmonary infarction

Sequestro extralobar com hemotórax secundário a infarto pulmonar

Darcy Ribeiro Pinto Filho, Alexandre José Gonçalves Avino, Suzan Lúcia Brancher Brandão

J Bras Pneumol.2009;35(1):99-102

Abstract PDF PT PDF EN Portuguese Text

Pulmonary sequestration is an uncommon condition that accounts for 0.5-6% of all pulmonary malformations and is typically diagnosed in childhood. Of the two forms of pulmonary sequestration, intralobar and extralobar, the latter is less frequently encountered. The current report describes the case of a 32-year-old female patient with chest and abdominal pain. Imaging (chest X-rays and computed tomography scans of the chest) revealed consolidation and pleural effusion. The initial thoracocentesis revealed hemothorax. Subsequent diagnostic video-assisted thoracoscopy revealed extralobar pulmonary sequestration. Consequently, the therapeutic decision was to make the conversion to thoracotomy in order to resect the lesion and safely ligate the intercostal vascular pedicle.

Surgical treatment of primary spontaneous pneumothorax on the first episode

Tratamento cirúrgico do pneumotórax espontâneo primário no primeiro episódio

Darcy Ribeiro Pinto Filho, André Germano Leite, Fabíola Délia Perin, Ronaldo Barbieri

J Bras Pneumol.2001;27(3):153-157

Abstract PDF PT

Purpose: To assess the results of the surgical treatment of primary spontaneous pneumothorax (PSP) by means of axillary thoracotomy, blebs resection and abrasive pleurodesis, by comparing the results with the different options of treatment, and to discuss the surgical approach as the best therapeutic option for patient with the first occurrence of PSP. Material and methods: 35 axillary thoracotomy with abrasive pleurodesis for the treatment of PSP were carried out at the Department of Thoracic Surgery of the University of Caxias do Sul between January 1996 and March 1999. Results: 23 patients with their first episode of PSP and 12 patients in their second episode were treated. The pleural drains were kept for in an average period of 2.7 ± 1.6 days. The average time in hospital was about 4.9 ± 2.4 days. Morbidity was 8.5% and mortality rate was zero. There was no relapse in an average period of 22 months of follow-up. Conclusion: The indication of axillary thoracotomy and abrasive pleurodesis to the patients with primary spontaneous pneumothorax (PSP) at the first or recurrent episode showed low rates of morbidity and no relapse, besides short periods of hospitalization and pleural drain permanence. The possibility of indication as the first therapeutic method for the PSP should be considered.

Objective: To evaluate the efficacy of the joint use of cervical mediastinoscopy and video-assisted thoracoscopy for the sampling of mediastinal lymph nodes in patients with non-small cell lung cancer (NSCLC) and candidates for pulmonary resection. Methods: Sixty-two patients diagnosed with NSCLC were submitted to cervical mediastinoscopy and video-assisted thoracoscopy. The samples obtained (from paratracheal chains, anterior and posterior subcarinal chains, paraesophageal chains and pulmonary ligament) were submitted to frozen section analysis. The following variables were also evaluated: age; gender; weight loss; diagnostic method; tomographic findings; histological type; staging; and location and size of the primary tumor. Results: In 11 patients, mediastinoscopy showed no involvement of the subcarinal chain, whereas such involvement was identified when video-assisted thoracoscopy was used: positive predictive value = 88.89% (95% CI: 51.75-99.72); negative predictive value = 94.34% (95% CI: 84.34-98.82); prevalence = 17.74% (95% CI: 9.2-29.53); sensitivity = 72.73% (95% CI: 39.03-93.98); and specificity = 98.77% (95% CI: 93.31-99.97). In 60% of the patients with involvement of the posterior subcarinal chain, the primary tumor was in the right inferior lobe. (p = 0.029) Conclusions: The joint use of cervical mediastinoscopy and video-assisted thoracoscopy for the evaluation of posterior mediastinal lymph nodes proved to be an efficacious method. When there is no access to posterior chains by means of ultrasound with transbronchial or transesophageal biopsy, which dispenses with general anesthesia, this should be the method of choice for the correct evaluation of mediastinal lymph nodes in patients with NSCLC.
