EVALUATION OF VENOGRAPHIC FINDINGS OF "FINE-NETWORK PATTERN" DURING ENDOSCOPIC INJECTION SCLEROTHERAPY

Abstract

Endoscopic injection sclerotherapy (EIS) has used widespreadly and a transparent overtube made EIS much easier with its clear visual field. We succeeded to get the venographic findings of "fine-network pattern (FNP)" for the small varices during EIS under negative pressure control.The characteristics of FNP on varicography are described below. 1) FNP can be demonstrated on EIS for small varices, after major varicose vein has been thrombosed. 2) Small varices has been thrombosed with no ulceration by only one injection of FNP on varicography. 3) No patients who were received intravariceal injection to get FNP on varicography have stenosis after EIS. 4) To get FNP on varicography is probably the final aim of treatment with EIS by intravariceal injection technique.
