Abstract

STUDY OBJECTIVES:

The connective tissue alterations in varicose vein wall are supposed to be one of the main causes of primary varicose vein (main sign of human lower limbs chronic venous insufficency).

METHODS:

5 varicose vein samples from 5 patients undergoing stripping surgery of long saphenous vein were compared with 5 control samples of healthy (non-dilated) long saphenous veins from necroptic material (with no history of varicosis). They were fixed in a Baker solution, processed by use of light microscopic method, cut to ultra-thin sections (4-5 microm) and stained with PicroSirius Red for collagen. Sections were scanned with light microscope (Leica, Germany) and camera Canon S50 (Germany) and analysed by morphometric programme Image J v.1.38g (National Institute of Health, USA).

RESULTS:

In the group of healthy (non-dilated) veins the mean collagen I/III ratio value was 31.40 and in the group of varicose veins the mean collagen I/III ratio was 12.35; the difference is statistically significant: healthy veins contain significantly more of collagen subtype I and varicose veins contain significantly more of collagen subtype III in their walls.

CONCLUSION:

The statistically significant difference in the collagen I/III ratio between the groups of healthy (non-dilated) and varicose (dilated) vein walls is worthy of further following (Tab. 2, Fig. 7, Ref. 12). Full Text (Free, PDF) www.bmj.sk.
