Clinical Application Of Real-time Virtual Navigate System In Percutaneous Neurolytic Celiac Plexus Block

ObjectTo study the clinical efficacy, safety and feasibility of real-time virtual navigation system (RVS) used in percutaneous neurolytic celiac plexus block (PNCPB).MethodsDuring May of2013to May of2014, a total of41cases were treated percutaneous neurolytic celiac plexus block under real-time virtual navigation system guided. All the patients were under intense pain because of malignant tumor in upper abdomen.Conventional analgesic solution was implement to all the patients before percutaneous neurolytic celiac plexus block. In41patients,22patients’retroperitoneal anatomical structure could not be showed clearly under ultrasound. After neurolytic celiac plexus block, we collected the patients’VAS numbers at the1st day,7th day,30th day and90th day respectively, and compared these numbers to the VAS numbers before neurolytic celiac plexus block. According to the data, we evaluated the clinical effects and recorded the complication caused by percutaneous neurolytic celiac plexus block, then evaluated comprehensively the clinical effects of pain control under real-time virtual navigation guided percutaneous neurolytic celiac plexus block.ResultAll patients were treated successfully under real-time virtual navigation guided neurolytic celiac plexus block. The numbers of VAS at the1st day,7th day,30th day and90th day after operation were significantly lower than those of VAS before treatment, the differences were statistically significant (P<0.05). The total effective rate of pain control showed a trend of gradual decline during the increase of time. There was no serious complications occurred in these patients except one acute pancreatitis.ConclusionReal-time virtual navigate system guided percutaneous neurolytic celiac plexus block is safe and effective, especially for patients whose retroperitoneal anatomical structure could not be showed clearly under conventional ultrasound.
