bifurcation

Theoretical medicine
A point in a dynamic system in which there is an abrupt change in the system’s behaviour; bifurcations occurs when 1+ of a system’s parameters reach a critical value. A change in the stability or types of solutions which occur as a parameter is varied in a dissipative dynamic system; the change can be seen as a bifurcation point in a graph of the parameter being varied vs one of the properties of the solutions.
 
Vox populi
A splitting into 2 parts.

Clinical trials
BIFURCATION
Evaluation of the Cypher sirolimus-eluting stent in the treatment of patients with bifurcation. A trial comparing the use of either one drug-eluting stent in the main branch and provisional stenting in the side branch or definitive stents in both vessels.
 
Results
Major acute cardiac events and target vessel revascularisation in CABG patients was 19% in stent + provisional stent patients and 14% in stent + PTCA (definitive) patients.

bifurcation

A fork or double prong. Bifurcations are very common in blood vessels and in the bronchial ‘tree’ of the lungs. At a bifurcation the sum of the cross-sectional area of the two branches usually exceeds that of the parent branch. Since this happens many times, there is a progressive increase in the unit volume of the system.
