Diagnosing unusual conditions
Doppler scan
Pulse in foot arteries was suspiciously low six months after diagnosis. Pearl was referred to a Vascular Surgeon who performed a doppler scan of both legs. The doppler scan measures pressure at various parts of the leg and ankle and compares that to the brachial pressure – that of the upper arm, typical of usual blood pressure readings. An ankle/ brachial index is derived for each section of leg or ankle by dividing the leg reading by the brachial reading. Before results were obtained by Pearl we rushed her to the hospital ER on an emergency basis to check out major circulation problems in both legs.
