Bilateral Endobiliary Biopsy and Tumor Stricture Recanalization By Endoluminal RFA With Subsequent Stenting Using PTBD Fistuli
01. Contrast is injected via the right side PTC catheter 02. Guide wire is conducted through the stricture 03. Guide wire is conducted from the left side also 04. Endoluminal biopsy forceps is open 05. Forceps is closed – biopsy is done 06. Biopsy is performed from right side also 07. Tumor block is processed using 8 Fr diameter bipolar endoluminal RF electrode 08. Stents are positioned bilaterally 09. Both stents are expanded in tumor stricture area 10. Biliary patency complete restoration is documented 11. Movie file – enduluminal biopsy using left PTBD fistula
CT Guided Biopsy Of Posterior Mediastinum
CT angiography – the biopsy target is identified in posterior mediastinum CT – Puncture site Markers on the Skin Surface CT– The needle is inserted beyond the pleura and adequate direction is documented CT – The needle is introduced to the target surface CT – Biopsy needle in the target
