新生儿肾上腺出血的超声评价

目的 :探讨新生儿肾上腺出血的发病因素以及声像图特征、转归。方法 :2 5例住院新生儿仰卧位双侧肋下冠状和横断扫查肾上腺及肾脏。结果 :2 5例肾上腺出血患儿 ,男 17例、女 8例 ,右侧肾上腺出血 2 0例、左侧 5例 ,其中 3例分别合并肝血肿、肾周血肿和阴囊血肿。肾上腺出血声像图特征为肾上腺区低或中强混合性回声肿块。结论 :新生儿肾上腺出血的主要发病因素为产前或生产中窒息、巨大胎儿、难产及暴力性损伤 ,临床表现缺乏特异性。声像图具有特征性表现 ,成为本症的主要诊断方法 ,常见的合并症为肾静脉血栓、阴囊血肿。肾上腺出血 6～8周后吸收缩小甚至消失 ,可残留肾上腺钙化

Ultrasonographic Evaluation of Neonatal Adrenal Hemorrhage

Objective:To discuss the sonographic manifestations, the pathogenesis and the prognosis of neonatal adrenal hemorrhage (NAH).Methods: Twenty five newborn's adrenals and kidneys were scaned in coronary and transverse sections when the baby in supine or oblique position.Results:There are 20 patients with right adrenal hemorrhage and 5 patients with left. Three patients associate with hepatic hemorrhage, perirenal hematoma and scrotal hematoma.The NAH appeared as mix mass in the area of neonatal adrenal.The main pathogenesis of NAH is due to perinatal asphyxia,large size of the baby, difficult delivery or any accident violence. Conclusion:sonograms have specific features of NAH being the main tool for examination. NAH often associates with renal vein thrombosis and scrotal hematoma.Adrenal hemorrhage may disappear after 6-8 weeks with calcification left.
