What percentage of untreated calf DVTs will likely propagate centrally?

The percentage of untreated calf deep vein thromboses (DVTs) that are likely to propagate to central veins, such as the popliteal or femoral veins, is recognized to be approximately 25%. This statistic is important in understanding the risks associated with untreated DVTs.

Calf DVTs may initially present with less severe symptoms compared to more proximal DVTs, but there is significant potential for complications if they are left untreated. Propagation of the thrombus can lead to embolization, which in turn increases the risk of pulmonary embolism, a serious condition.

Understanding this prevalence is critical for medical professionals, as it guides the clinical decision-making process regarding diagnosis, treatment options, and patient education on the importance of timely intervention for DVTs.
