Contractile effects of arginine analogues on human internal thoracic and radial arteries
2000
Abstract Objectives: Plasma levels of endogenous guanidino-substituted analogues of L -arginine are increased in various pathologic conditions. In the present study we determined the effects of some of these compounds on basal and stimulated release of nitric oxide in human internal thoracic and radial arteries. Methods: Rings of human internal thoracic and radial arteries were obtained from 16 multiorgan donors. The rings were suspended in organ baths for isometric recording of tension. Results: N G -monomethyl L -arginine (10 –6 to 10 –3 mol/L) and N G ,N G -dimethyl L -arginine (10 –6 to 10 –3 mol/L) caused concentration- and endothelium-dependent contractions. Maximal force of contracti…
Extrathoracic Arteriosclerotic Vascular Changes Preclude the Use of the Internal Thoracic Artery for Coronary Artery Bypass Grafting
1996
During a two-years period we have treated 6 patients where use of the internal thoracic artery for coronary artery grafting was precluded because of extrathoracic arteriosclerotic vascular lesions. In four patients with severe aorto-iliac occlusive disease preoperative digital angiography demonstrated collateralisation of the lower extremity by either the left, right, or both internal thoracic arteries (ITA). In these cases use of the ITA was excluded in order to preserve the collateral supply and coronary bypass grafting was performed using only saphenous vein. In two patients with proximal occlusion of the left subclavian artery the right ITA was used as in-situ bypass to graft the left a…
Nipple-sparing mastectomy and breast reconstruction with a deep inferior epigastric perforator flap using thoracodorsal recipient vessels and a low l…
2018
Background Nipple-sparing mastectomy poses challenges in providing esthetically-pleasing immediate autologous breast reconstruction. This study was to investigate the outcomes of nipple-sparing mastectomy with breast reconstruction using free abdominal flaps between two different recipient sites. Methods Between 2010 and 2016, 79 patients who underwent nipple-sparing mastectomy with autologous breast reconstruction using thoracodorsal (TD) vessels in 30 cases or internal mammary (IM) vessels in 49 cases were investigated. Demographics, intraoperative findings, complications, and quality of life using Breast-Q questionnaire were compared between two groups. Results All flap survived. There w…
