Clinicopathological study of varicose veins (descriptive study)

Varicose Veins

Under normal circumstances, blood collected from superficial venous capillaries is directed upward and inward via one-way valves into superficial veins. These in turn drain via perforator veins, which pass through muscle fascia into deeper veins buried under the fascia. Leakage in a valve causes retrograde flow back into the vein. Unlike deep veins which are thick-walled and confined by fascia,...

To study their characteristics, the authors did a retrospective clinicopathological analysis of 124 oral biopsies that were diagnosed as odontogenic cyst...

Intimal changes in varicose veins: an ultrastructural study.

In order to study the structural changes in the intimal layer of varicose veins, we prospectively collected a total of 23 vein specimens from both the normal proximal thigh long saphenous (LSV) in 3 young trauma patients and from the unstripped proximal LSV near the sapheno-femoral junction and the distal calf blowouts in 10 primary varicose veins patients. Paraffin sections stained with hemato...

Varicose veins and haemorrhoids: findings in the Oxford-FPA study.

At recruitment to the Oxford-Family Planning Association (Oxford-FPA) study, oral contraceptive (OC) users were less likely to give a history of hospital treatment for varicose veins (VVs) than users of other contraceptive methods. Adjusted for age and parity, 1.6% of OC users gave such a history compared with 2.3% of diaphragm users and 3.9% of intrauterine device (IUD) users. We have examined...
