Hypothesis: Vasa Vasorum and Neovascularization of Human Coronary Arteries

TLDR

The presence and extent of vasa vasorum in coronary arteries remains disputed, with early observations linking intimal proliferation and medial hypertrophy to these vessels. Winternitz et al. used India ink injection to reveal rich vascular channels around and penetrating sclerotic lesions in coronary arteries, indicating a likely source of neovascularization.

Abstract

ALTHOUGH the vasa vasorum, the nutrient vessels in the wall of the human aorta, have been studied in some detail,1 there has been disagreement concerning the presence or extent of vasa vasorum in the coronary arteries. As early as 1876 Köster2 suggested that the intimal proliferation and medial hypertrophy of "arteriitis" was related to the presence of vasa vasorum in the media and intima. In 1938 Winternitz et al.3 injected India ink into the wall of cleared coronary arteries and demonstrated the "presence of rich vascular channels surrounding and penetrating sclerotic lesions." They suggested that "here, undoubtedly, was the source . . ⋯
