Vasa Vasorum in Deep Vein Thrombus Recanalization

Vasa vasorum is a microvessel known as “the vessel of the vessels.” It is found in tunica media in the wall of blood vessels. It is normally not visualized due to its microscopic structure, but when enough extra pressure compresses the wall of a blood vessel, by the presence of an acute thrombus for an example, this microvessel can be visualized. This case study explains how to identify vasa vasorum by analyzing Doppler waveforms. Furthermore, this case study suggests that the appearance of vasa vasorum in the 3-month follow-up may indicate that the overall recanalization of a thrombus may be more complex than how it is suggested in a published case study by Brandao and his colleagues
