作者对9例疑诊嗜铬细胞瘤的高血压病人进行了腔静脉分段取血测定血浆游离与结合形式的儿茶酚胺(CA),其中5例经手术证实为嗜铬细胞瘤,并测定了摘除的6个肿瘤组织的CA含量。另4例非嗜铬瘤细胞病人包括原发性高血压、大动脉炎、先天性主动脉缩窄和肾血管性高血压各1例。本研究之目的:(1)了解非嗜铬细胞瘤高血压病人腔静脉各部位血浆游离与结 The authors performed blood sampling in 9 patients with hypertensive patients with suspected pheochromocytoma to determine plasma free and bound forms of catecholamines (CA). Five of them were confirmed to be pheochromocytomas by surgery and the removal was determined. The CA content of 6 tumor tissues. The other 4 non-chromocytoma patients included primary hypertension, aortic vasculitis, congenital aortic coarctation, and renal vascular hypertension in 1 patient each. The purpose of this study: (1) to understand the plasma dissociative and knots in various parts of the vena cava in non-hyperchromic cell tumor hypertensive patients
