Vascular Occlusion in a Porcine Flap Model: Effects on Blood Cell Concentration and Oxygenation
Background Venous congestion in skin flaps is difficult to detect. This study evaluated the ability of tissue viability imaging (TiVi) to measure changes in the concentration of red blood cells (CRBC), oxygenation, and heterogeneity during vascular provocations in a porcine fasciocutaneous flap model. Methods In 5 pigs, cranial gluteal artery perforator flaps were raised (8 flaps in 5 pigs). ...
متن کاملEffect of vascular occlusion on radiofrequency ablation of the liver: results in a porcine model.
OBJECTIVE This study determined the effect of vascular occlusion on radiofrequency lesion shape, volume, and temperature in a porcine liver model. SUBJECTS AND METHODS Radiofrequency lesions (n = 33) were created in the livers of six domestic pigs in vivo using a multiprong radiofrequency electrode. Lesions were randomly assigned to one of four vascular occlusion groups: portal vein, hepatic ...
متن کاملAbstract 111: Rapid Detection of Acute Vascular Occlusion Using Oxygen Monitoring in a Rat Myocutaneous Flap Model
PURPOSE: Free tissue transfer requires close postoperative monitoring for vascular occlusion. Vascular compromise commonly occurs in the immediate postoperative period in association with failure of the micro-vascular anastomosis. The resiliency of tissue to hypoxia and ischemia is crucial to the success of the surgery. It is estimated that 6 percent to 25 percent of skin flaps require a second...
متن کاملenhanced myocardial vascularity and contractility by novel fgf-1 transgene in a porcine model of chronic coronary occlusion
background: angiogenesis gene therapy has long been sought as a novel alternative treatment for restoring the blood flow and improving the contractile function of the ischemic heart in selected clinical settings. angiogenic fibroblast growth factor-1 (fgf-1) is a promising candidate for developing a promising gene therapy protocol due to its multipotent ability to stimulate endothelial cell (ec...
متن کاملPorcine Model for Gluteal Artery Perforator Flap: Anatomy and Technique
1 BACKGROUND Although flap anatomy is well studied on cadavers and microsurgical techniques are well practiced on rats, still there are few training models for learning the techniques of perforator flap harvesting. The cadaver has no bloodstream, so accuracy of dissection cannot be evaluated and flap viability cannot be verified. Training on humans carries a high risk of flap damage. A living m...
