SIGNO DEL YIN-YANG: LA DUALIDAD DEL PSEUDOANEURISMA

pseudoaneurysm is a collection of blood adjacent to a punctured blood vessel, connected with it and characterized by an inner bidirectional flow in relation with systole and diastole. this diagnosis is usually based on color doppler examination findings, among which we can highlight the visualization of a collection with a two-way flow pattern, with a red and a blue component, which resembles the chinese yin yang symbol. the increase in the number of angiographic procedures and arterial catheterization requires from radiologists the ability to properly diagnose the complications these procedures may entail.
