Percutaneous Trans-Thoracic Procedures in Children With Tumors of Thoracic Wall, Mediastinum and Lung. The Experience of a Single Institution
Background
While percutaneous trans-thoracic procedures (PTTP) are commonly performed in adults with
tumors of thoracic wall, mediastinum and lung, the experience is limited in children, in whom
however less invasive methods should be the choice for the diagnosis or the identification of
small pulmonary nodules that need to be removed, sparing lung tissue. The results of the PTTP
performed by the interventional radiologists in our Pediatric Surgery Department are analyzed.
Methods
CT-guided biopsies, utilizing a 64-slice CTscanner, with low-radiation dose, were performed
applying the coaxial technique with 16-18G needles with a single tissue path. For localization
of lung nodules before surgery, two 20G-hook wires were positioned beyond the nodule. CT
images after each manipulation of the needles were obtained. US-guided biopsies were
performed either with or without coaxial technique through a needle bracket. Younger patients
required sedation. All patients underwent a chest radiogram two hours after the procedure and
remained under observation for 24 hours.
Results
From January 2015 to March 2019, 23 procedures were performed in 22 patients (Age:16M-
19Y): 6 patients underwent CT-guided biopsy (4 lung nodules, 2 mediastinal mass); 3
underwent 4 CT-guided hook-wire localization of pulmonary nodules, just before surgery; 13
underwent US-guided biopsy (posterior mediastinum 2; anterior mediastinum 5,
thoracic/intrathoracic mass 5). Adequate core biopsies were obtained in all patients, except
three, who underwent thoracoscopy/thoracotomy. The hook-wires were successfully
positioned in all cases, as confirmed by histology. After the procedure, two patients presented
perilesional hemorrhage and one pneumothorax, but they did not required treatment.
Conclusion
PTTP were successful in most patients, without significant complications. These techniques
should be encouraged to avoid diagnostic aggressive surgical approaches in children with
cancer. For all cases a multidisciplinary team is essential to discuss the indications and planning
the procedures

Fatal pericardial tamponade after superior vena cava stenting.
Contains fulltext :
80672.pdf (publisher's version ) (Closed access)We discuss a fatal complication of percutaneous superior vena cava (SVC) self-expandable stent placement in a patient with superior vena cava syndrome (SVCS). The SVCS was caused by a malignant mediastinal mass with total occlusion of the SVC. Twenty-four hours after the procedure, the patient died of a hemopericardial tamponade. In the literature, only seven cases have been described with this life-threatening complication. Patients with a necrotic tumor mass are more likely to develop this complication. Knowledge of this complication may increase patient survival
Toward a Buddhist systems methodology 1: Comparisons between Buddhism and systems theory
This paper compares some key concepts from Buddhism with ideas from different traditions of systems thinking. There appear to be many similarities, suggesting that there is significant potential for dialogue and mutual learning. The similarities also indicate that it may be possible to develop a Buddhist systems methodology to help guide exploration and change within Buddhist organisations
