RESUMO
The objective of this article is to report our first experience of CT guided percutaneous thoracic biopsy and to demonstrate the accuracy and safety of this procedure. This was a retrospective study of 28 CT-Guided Percutaneous Needle Biopsies of the Chest performed on 24 patients between November 2014 and April 2015. Diagnosis was achieved in 18 patients (75%), negative results were found in 3 patients (12,5%). Biopsy was repeated in these cases with two positive results. Complications were seen in 7 patients (29%), Hemoptysis in 5 patients (20%), Pneumothorax in 1 patient (4,1%) and vaso-vagal shock in 1 patient (4,1%). CT Guided Percutaneous Needle Biopsy of the Chest is a safe, minimally invasive procedure with high sensitivity, specificity and accuracy for diagnosis of lung lesions.

PURPOSE: The purpose of this study is to present an alternative technique for management of a type II endoleak associated with aneurysm sac enlargement. TECHNIQUE: We report the use of a transseptal needle-sheath system for a transcatheter transcaval embolization (TTE) in a 3-staged treatment of a persistent type II endoleak after abdominal EVAR. Inferior vena cava is cannulated through a femoral venous access, and aneurysmal sac access is gained with a puncture through the walls of the 2 vessels at the site where the vein is adjacent to the aneurysm. The whole system (sheath-dilator-needle) is then advanced across the vascular walls into the aortic sac. Thus, embolization with glue is performed. CONCLUSION: The TTE using a transseptal needle-sheath system demonstrated to be feasible and effective to treat a persistent type II endoleak after failure of 2 attempts of transarterial embolization of the feeding vessels.
