The renal papilla has a double blood supply - from both the vasa recta and the calyceal arteries. The importance of the latter supply is not established. A case of polyarteritis associated with papillary necrosis is reported, in which the calyceal vessels, supplying the area, show acute necrotizing arteritis and occlusion. The pathophysiological and clinical implications are discussed.
肾乳头有双重血液供应，分别来自直小血管和肾盏动脉。后者供应的重要性尚未明确。本文报告了一例与乳头坏死相关的多动脉炎病例，其中供应该区域的肾盏血管显示出急性坏死性动脉炎和闭塞。文中讨论了其病理生理及临床意义。
