title: Retrocrural splanchnic nerve alcohol neurolysis with a CT-guided anterior transaortic approach.
abstract: Retrocrural splanchnic nerve alcohol neurolysis with a CT-guided anterior transortic approach, a new method for splanchnic block alleviation of chronic abdominal pain, is described. Ten patients with chronic abdominal pain requiring narcotic treatment, six with pancreatic carcinoma, one with gastric carcinoma, two with chronic pancreatitis, and one with pain of unknown etiology, were referred for splanchnic nerve neurolysis. With CT guidance, a 20 gauge needle was placed through the aorta into the retrocrural space at T11-T12, and 5-15 ml 96% alcohol was injected into the retrocrural space. Following the procedure, 6 of 10 patients were pain free, 2 patients had temporary pain relief, and 2 patients were without response. There were no significant complications. CT-guided anterior transaortic retrocrural splanchnic nerve alcohol neurolysis is technically feasible, easier to perform than the classic posterolateral approach, and may have less risk of complications. The success rate in this initial trial was reasonable and, therefore, this technique provides an additional method for the treatment of abdominal pain.
