Intercoronary Reflex

Intercoronary reflex. Demonstration by coronary angiography.

• There is a fairly widespread belief that injury to an artery leads to peripheral vasospasm, which sometimes involves nearby vessels as well as the one directly injured. This lias led to several attempts to deiennine whether injury to a coronary artery, by ligalion or einbolization, might cause spasm of the embolized vessel distal to the point of injury or constriction of other nonembolized br...

An experimental study on intercoronary reflexes.

There is no evidence in the anesthetized dog that occlusion of one of the three coronary arteries leads to vasoconstriction in the vascular areas irrigated by the other two arteries. On the contrary, occlusion of one coronary artery appears to lead to a decrease in the resistance of the two adjacent vascular beds in most experiments. The mechanisms and the implications of this effect arc discus...

[Distal intercoronary communication. A case report and medical literature review].

Direct connections between normal distal coronary arteries are rarely detected with angiography. In a 67-year-old man a diagnosis of intercoronary arterial continuity was established after ruling out collateral circulation secondary to coronary obstruction. Published reports of similar cases are reviewed.
