Bronchial arteriography and double embolization is to block the peripheral bronches of the bronchial artery with micro-gelatin particles and then the trunk of the artery with sponge gelatin. The blood flow from the artery trunk and from the rich arterial bronches which forms B-P bypass is blocked. By this way the embolization is more complete. Clinical observation of 93 cases shows that the success rate reached 91% which indicate that the massive hemoptysis could stopped by this method.
