Because the vessels of the hand are small and very responsive to stimuli, arteriography of the hand requires painstaking technique, temperature control, and sometimes vasodilator administration to produce sufficient radiographic detail. Twenty-five patients underwent arteriography of the hand, which was performed from a transfemoral approach to evaluate pathologic changes and the possibility of interventional treatment. Production of high-quality images by means of attention to technical factors particular to the hand permitted recognition of radiographic detail essential to diagnosis. Twelve patients had a history of trauma, and five patients had congenital lesions. In eight patients, atherosclerotic, vasospastic, or embolic arterio-occlusive disease was diagnosed. Interventional radiologic procedures such as thrombolysis, therapeutic embolization, and percutaneous transluminal angioplasty are important adjuvant or primary management options. Angiography of vascular hand lesions can yield high-quality diagnostic images when technical factors and physiologic variables are maximized. Differentiation between traumatic, congenital, and occlusive lesions is then possible.
由于手部血管细小且对刺激反应非常敏感，手部动脉造影需要精细的技术、温度控制，有时还需要使用血管扩张剂以产生足够的放射影像学细节。25例患者接受了手部动脉造影，造影通过经股动脉途径进行，以评估病理变化和介入治疗的可能性。通过关注手部特有的技术因素来生成高质量图像，从而能够识别诊断所需的放射影像学细节。12例患者有外伤史，5例患者有先天性病变。8例患者被诊断为动脉粥样硬化、血管痉挛或栓塞性动脉闭塞性疾病。介入放射学程序，如溶栓、治疗性栓塞和经皮腔内血管成形术，是重要的辅助或主要治疗选择。当技术因素和生理变量得到最大化时，手部血管病变的血管造影可以产生高质量的诊断图像。这样就可以区分创伤性、先天性和闭塞性病变。
