Radial Artery Spasm Clinical Trial

Official title: The Efficacy of Papaverine to Prevent Radial Artery Spasm During Transradial Cerebral Angiography: A Randomized Controlled Trial

Status Recruiting

Clinical Trial Summary

Rationale:Papaverine is effective on radial artery spasm during transradial cerebral angiography.

Purpose: This multicenter, randomized, placebo-controlled, double blind, phase 2b trial aims to investigate the effect and safety of papaverine in treating radial artery spasm during transradial cerebral angiography.

Clinical Trial Description

Radial artery spasm (RAS) is a common complication during transradial cerebral angiography. RAS can lead to severe pain and remains the most frequent cause of transradial angiography failure. There is currently no consensus on the prevention strategy for RAS.

Papaverine has anti vasospasm, sedative and analgesic effects. However, there is no evidence for the efficacy of papaverine in preventing RAS.

This multicenter, randomized, double blind, placebo-controlled trial aims to investigate the effect and safety of papaverine in treating radial artery spasm during transradial cerebral angiography. ;
