Multicenter Study Clinical TrialAlteplase for the treatment of central venous catheter occlusion in children: results of a prospective, open-label, single-arm study (The Cathflo Activase Pediatric Study).
Alteplase is approved for use in the restoration of function to occluded central venous access devices (CVADs); however, there are few prospective studies in children. This study was undertaken to evaluate the safety and efficacy of alteplase in the treatment of CVAD occlusions in a pediatric population. ⋯ The administration of alteplase is safe and effective for the restoration of function to CVADs in pediatric patients.

Pneumothorax as a complication of percutaneous radiofrequency ablation for lung neoplasms.
The present study was performed to determine the frequency of the complication of pneumothorax after radiofrequency (RF) ablation for lung neoplasms and risk factors affecting such pneumothoraces. ⋯ The frequency of pneumothorax after RF ablation in our experience is similar to the frequency of pneumothorax after lung biopsy reported in the literature. Various conditions for RF ablation did not influence the incidence of pneumothorax. Emphysema was the only individual factor that correlated significantly with the development of iatrogenic pneumothorax.

Comparative StudyControl and performance characteristics of eight different suction biopsy devices.
To determine the control and performance characteristics of eight different suction biopsy devices. ⋯ Each of the suction biopsy devices has unique advantages and disadvantages. Suction biopsy devices with the least favorable overall performance were the conventional syringe and the conventional syringe with a plunger lock. The highest overall performance was seen with the RPD and RPD syringe holder.

Case ReportsBronchopleural fistula treatment with use of a bronchial stent-graft occluder.
The purpose of this report is to describe our experience in the successful treatment of two patients with postpneumonectomy bronchopleural fistula (BPF). With use of computed tomography reformatting, the stent-graft occluders were tailored to precisely fit the fistula site and remnant bronchus stump. These were placed under fluoroscopic guidance via a preexisting chest tube tract in one case and via an open thoracostomy window site in the other. The BPFs were successfully occluded without complications, and the stent-graft occluders remained stable in position for 1 year and 6 months of follow-up, respectively.
