Histomorphometric and sympathetic innervation of the human internal thoracic artery
INTRODUCTION Internal thoracic artery (ITA) is an established arterial graft for the coronary artery by-pass surgery. Special micro-anatomical features of the ITA wall may protect it from age related pathological changes. One of the complications seen after coronary artery bypass grafting is vasospasm. Sympathetic nerves may be involved in vasospasm. OBJECTIVE To ascertain the sympathetic inn...
متن کاملHistomorphometric and sympathetic innervation of the human superficial temporal artery
CONTEXT Following microvascular surgeries, stenosis and spasm of the arterial graft or the recipient vessel are serious complications which are often caused by intimal hyperplasia and perivascular nerves, respectively. AIMS The purpose of this study was to understand the characteristics of arterial wall and sympathetic innervation of the human superficial temporal artery (STA) and also, the e...
متن کاملHistomorphometric and sympathetic innervation of the human posterior intercostal artery and its clinical importance.
The purpose of this investigation was to study the characteristics of arterial wall and sympathetic innervation of the human posterior intercostal artery (PIA) in order to assess its suitability as an arterial graft for vascular surgeries. Fifty PIA samples were obtained from 25 cadavers (18 males and 7 females). Samples were divided into three age groups: group 1: 19-40 years; group 2: 41-60 y...
متن کاملSkeletonization of internal thoracic artery affects its innervation and reactivity.
OBJECTIVE The studies showing the superior characteristics of ITA graft and its impact on the clinical results of coronary artery surgery were performed with ITA harvested almost exclusively as a pedicle. This study assesses the impact of ITA skeletonization on its innervation and reactivity. METHODS Segments of skeletonized and non-skeletonized ITA were stained with antibodies against protei...
متن کاملThe internal thoracic artery in human foetuses.
The aim of this study was to examine the internal thoracic artery (ITA) in human foetuses. The research material consisted of 32 human foetuses (18 female, 14 male) from the 21(st) to 24(th) week of intrauterine life. After intravascular injection with white latex LBS 3060, the foetuses were fixed in 10% neutral formalin solution. The whole course of the ITA was prepared. Photographic documenta...
