THE EFFECT OF CARDIAC LYMPHOSTASIS ON THE MICROCIRCULATION OF THE HEART

---

Abstract

The effect of cardiac lymphostasis on the microcir­culation of the heart was studied in 18 dogs. By ligation of the main lymph trunks and regional lymph nodes of the heart, cardiac lymphoedema -- lympho­genic cardiomyopathy -- was induced in 9 dogs, while 9 served as control animals. For microcircula­tory investigations:

1) gelatin Indian ink injection, 2 benzidine reaction,

3) PVC injection corrosion preparation was applied.

Characteristic changes were demonstrated in the mi­crocirculation and capillary circulation of the heart in cardiac lymphostasis. In some capillaries -- mainly where interstitial oedema exists -- the capillary cir­culation decreased: inhomogeneously vessel-free spots were formed in the heart. Around the vessel­ free capillaries, elongated capillaries were found in cluding very dilated pre- and post-capillary vessel sections. Arteriovenous shunts can be revealed in the heart in consequence of lymphoedema.

The pathogenesis of the microcirculatory circulation changes caused by cardiac lymphostasis was discussed.
