Abstract

Palliative transcatheter tumour embolization was performed in 40 patients having non-operable renal carcinoma using particulate, semiliquid and liquid embolizing substances. In addition the Gianturco-Andersen-Wallace (GAW) coil was applied in 7 patients showing remarkable vascular recanalization. Effects of the angiotherapeutic procedures were controlled by re-angiography in 33 cases. Sonography was performed in 15 cases and computed tomography in 24 patients before and after embolization. It was found that the re-angiography was necessary: a) as thhe first control to prove the extension of thrombotic obstruction and to assess the remaining collateral circulation; b) as an indication for re-embolization in 7 cases showing remarkable recanalization. Follow-up computed tomography and sonography helped to observe the long-term changes: shrinkage of the tumour and the embolized kidney, and recurrence of the tumor growth or local retroperitoneal and liver metastases. The analysis of our observations confirms the value of re-angiography for the short-term follow-up study. Sonography and computed tomography are reliable procedures for the further follow-up of patients.

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.
