Changes in capillary diameters in pregnancy-induced hypertension.

Objective: To compare capillary diameters, density and reactivity in high-risk pregnancies complicated by pregnancy-induced hypertension (PIH) to other high-risk pregnancies not affecting microcirculation (O).

Methods: Patients hospitalized at a tertiary referral center from January to May 2012 were enrolled in the prospective pilot study. Five microscopic fields were recorded from the nailfold for capillary diameters and functional capillary density assessment.
