Objective To explore the affecting factors on sinus rhythm maintenance after electric cardioversion for patients with atrial fibrillation (Af) after cardiac valve replacement. Methods One hundred fifty two valvular disease patients with Af after cardiac valve replacement were randomized to 2 groups: Amiodarone group and control group (without anti arrhythmic drugs) after cardioversion. Af recurrence was observed during one year follow up. Results (1) No significant difference of Af recurrence betwe...
目的 总结彩色多普勒超声(彩超)结合钼靶X线摄片标记定位对无临床体征乳腺肿块的定位诊断价值。 方法 2010年3月-2011年10月对48例彩超和钼靶X线检查发现可疑病灶而无任何临床体征的患者,在彩超引导下穿刺病灶金属导丝标记定位,并结合钼靶X线检查切除病灶,同时快速冰冻活检明确诊断。 结果 48倒中有11例确诊为乳腺癌(浸润性导管癌7例,导管内癌4例),37例为良性病变(纤维瘤5例,导管内乳头状瘤4例,乳腺腺病28例)。冰冻切片病理检查与术后石蜡病检结果一致。 结论 彩超引导下穿刺钢丝标记定位活检结合钼靶X线摄片,有效地解决了乳腺细小钙化和微小病灶活检术中精确定位和完整切除的难题,对无临床体征的微小乳腺肿块的诊断准确、可靠、实用。
