RESUMEN
PURPOSE: We evaluated technical success, safety and effectiveness of percutaneous radiological gastrostomy (PRG) with a modified technique: single puncture and double anchor. MATERIALS AND METHODS: From January 2008 to June 2011, 163 patients underwent PRG with a single-puncture double-anchor technique. The stomach was punctured with a 17-gauge Chiba needle, and gastropexy was performed by placing two anchors in the gastric lumen. Finally, a 12-F Wills-Oglesby percutaneous gastrostomy catheter was inserted. Technical success and complications at 30 days were evaluated on the basis of imaging and patients' medical records. RESULTS: PRG was successfully completed in all 163 patients. Only a single puncture was required in all patients. The average PRG procedure time was 9 min. Three patients had major complications: haemorrhage (n=2) and pneumoperitoneum (n=1). Ten patients had minor complications: tube malfunction/breakage (n=9), and leakage through the insertion site (n=1). Two patients died 30 days after the procedure. CONCLUSIONS: Single-puncture double-anchor PRG is a fast, safe and effective technique.

PURPOSE: The aim of this study was to evaluate the effectiveness of the new Amplatzer vascular plug (AVP) for the occlusion of vascular abnormalities and peripheral vessels, especially those with a large diameter. MATERIALS AND METHODS: The new device was used for the occlusion of five internal iliac arteries to prevent retrograde endoleak following endograft repair, three left subclavian arteries for the treatment of type II endoleaks after positioning thoracic aorta stent-grafts, one pulmonary arteriovenous malformation, one haemodialysis fistula in a patient with forearm oedema and one large gastric varix in a patient who had undergone transjugular intrahepatic portosystemic shunt (TIPS) for haemorrhage. RESULTS: The five internal iliac arteries and the three left subclavian arteries were successfully occluded within 8 and 5 min, respectively. The pulmonary arteriovenous fistula was closed within 3 min and percutaneous oxygen saturation rose from 73% to 93%. The haemodialysis fistula was closed with one device within 4 min. The gastric varix was embolised with two AVPs and two coils within 12 min. CONCLUSIONS: The AVP is an effective device for occluding large diameter vascular abnormalities and peripheral vessels. It is inexpensive and enables safe and low-risk embolisation, with saving of time and requiring only low X-ray dose.
