Effect of foot stato-dynamic disorders on hemodynamics of the lower limb using strain-gauge plethysmography.

Background: The plantar venous pump (PVP), composed of deep plantar veins, is the most distal contributor to venous return from the lower limbs. A pressing need still exists to assess how plantar muscle contraction and gait affect PVP function, how foot stato-dynamic disorders (FSDs) can contribute to venous insufficiency, and how venous return can be optimally stimulated. Our first objective is to compare the venous blood hemodynamics in lower limbs between healthy subjects with a FSD and healthy subjects without a FSD to understand the influence of foot morphology in the performance of the PVP.

Frequency of lipoedema in patients consulting a vein clinic for mild to moderate superficial venous disorder with symptoms: A retrospective analysis.

Introduction: Lower limb lipoedema is a chronic condition of the adipose connective tissue of the skin that affects women. Its frequency is not well known, hence the main objective of this study.

Method: Retrospective analysis of the records of phlebology consultations in private practice in a single center from April 2020 to April 2021.

Effect of dysmorphic plantar arch on venous hemodynamics of the lower limb.

Background: The role of the plantar venous pump (PVP) on venous return is evident but the effects of the foot morphology have never been characterized properly.

Method: 52 healthy volunteers-26 with normal plantar arch (control) and 26 with dysmorphic plantar arch (in two subgroups: 13 flat feet, 13 hollow feet)-were included. Using Doppler ultrasound, we measured the diameter and the peak systolic velocity in the large veins of the lower limb after PVP stimulation by manual compression and bodyweight transfer.

Four new cases of isolated foot vein thrombosis: Is the first metatarsal interspace perforator responsible?

Isolated foot vein thrombosis is an infrequently reported condition, the cause of which is still questioned. Four new cases are detailed, covering different physio-pathological situations ranging from plantar vein to Lejars' sole thrombosis. They are compared to the literature.
