Technical advances in cardiac surgery have made accessible previously remote regions within the heart and great vessels; nevertheless, limitations in the ability to locate intramyocardial foreign bodies with precision utilizing conventional radiographic techniques, together with the frequent inability to palpate a foreign body located within the walls of the heart chambers, has dampened early enthusiasm for their removal. Despite this, the recognized complications associated with nonoperative management continue to militate for an aggressive approach. The following case illustrates the use of operative high-frequency ultrasonography in the exact localization of an intramyocardial foreign body. The precision thus afforded minimizes operative time, confines the size of the necessary ventriculotomy, and greatly facilitates successful removal.
心脏外科手术技术的进步已使心脏和大血管内先前难以触及的区域变得可及;然而,利用传统放射学技术精确确定心肌内异物位置的能力有限,加上常常无法触诊位于心腔壁内的异物,这减弱了人们早期对取出异物的热情。尽管如此,与非手术治疗相关的公认并发症仍促使采取积极的治疗方法。以下病例说明了手术高频超声在心肌内异物精确定位中的应用。由此提供的精确性可将手术时间减至最短,限制必要的心切开术的范围,并极大地促进成功取出异物。
