Resuscitation and circulatory support using extracorporeal membrane oxygenation for fulminant pulmonary embolism 总被引:3,自引:0,他引:3
Fulminant pulmonary embolism (PE) with circulatory collapse is associated with a high mortality rate due to acute right ventricular failure and hypoxia. Immediate and appropriate resuscitation and circulatory support in the perioperative period is mandatory to prevent sudden death. Extracorporeal membrane oxygenation (ECMO) was recently introduced for extracorporeal life support in patients with circulatory collapse and has provided an excellent outcome. We report on the effectiveness of ECMO support for fulminant PE. Seven patients were placed on veno-arterial ECMO for circulatory collapse caused by fulminant PE refractory to conventional treatment. After resuscitation, all patients underwent pulmonary angiography, and thrombolytic therapy was administered in all 7 patients under ECMO support. Three patients who did not improve by thrombolysis underwent embolectomy with standard cardiopulmonary bypass. Two thrombolysis and 2 surgery patients were weaned from bypass and survived. The duration of support ranged from 18-168 h (mean = 67.8 +/- 67.1 h), with maximum bypass flow rates of 2.0-4.5 (mean = 3.5 +/- 0.9). There were no device-related complications during support. In total, 4 patients (57%) were successfully weaned from support and discharged from the hospital in good condition. All patients who survived required prolonged support (27, 82, 151, and 168 h). We conclude that resuscitation and circulatory support using ECMO can be effective, life-saving measures in cases of circulatory collapse caused by fulminant PE. 相似文献

We describe the case of a boy with steroid sensitive nephrotic syndrome and left pulmonary artery thrombo-embolism. Clinical
presentation initially suggested sepsis and respiratory signs were minor. Treatment with tissue plasminogen activator infused
into the pulmonary artery was successful.
Conclusion Pulmonary thrombo-embolism should be considered in unwell children with nephrotic syndrome.

经眼上静脉入路行海绵窦栓塞的应用解剖学 总被引:1,自引:1,他引:1
目的:为经眼上静脉入路行海绵窦栓塞术,治疗颈动脉海绵窦瘘提供解剖学依据。方法:成人头部标本24个,解剖观测眼上静脉及其眶外属支的形态、长度及外径等。结果:①眼上静脉由眶上静脉支和内眦静脉交通支组成。眶上静脉支穿经眶上孔处外径为1.3mm。内眦静脉外径为1.4mm,距内眦6~8mm,其交通支外径为1.4mm;②眼上静脉在眶腔内分为三段,外径平均达2.1~2.5mm。结论:经眼上静脉眶外属支入路具有可行性。 相似文献

肺动脉栓塞的彩色多普勒超声诊断 总被引:2,自引:1,他引:2
目的 探讨彩色多普勒超声诊断肺动脉栓塞的意义。方法 对临床诊断肺动脉栓塞患者18例行经胸超声心动图检查和下肢深静脉彩色多普勒超声检查。结果 18例患者中,超声检出肺动脉血栓直接征象10例,其中合并右室乳头肌下方血栓及三尖瓣前叶瓣环血栓各1例,合并下肢血栓9例。18例均有右房、右室增大,伴有三尖瓣重度返流,肺动脉重度高压(肺动脉收缩压为110~140mmHg)。结论 彩色多普勒超声是一无创、快速、简单易行的肺动脉栓塞诊断方法,对该病疗效观察及预后判断也有重要作用。 相似文献

目的评价单纯抗凝与导管内溶栓加抗凝治疗肺动脉栓塞疗效对比。方法经肺动脉造影或增强螺旋CT证实的急性肺动脉栓塞患者63例,随机分两组,一组单纯肝素抗凝32例,另一组导管内尿激酶溶栓加肝素抗凝31例。结果单纯抗凝治疗总有效率96.7%;导管内溶栓加抗凝治疗总有效率100%,但临床症状改善较快。单纯抗凝无效1例,经导管内溶栓后好转。经导管内溶栓出现消化道出血1例。本观察无1例死亡。结论单纯抗凝与导管内溶栓加抗凝治疗总有效率相近,无并发症出现。所以对无血液动力学改变的急性肺动脉栓塞单纯肝素抗凝即可取得确切疗效,可降低风险。 相似文献

Fibrocartilaginous embolus causing acute spinal cord infarction is a rare cause of acute-onset paraplegia or quadriplegia.
Few cases of survivors have been reported in the neurosurgical literature, with most reports involving post-mortem or biopsy
findings. There is little information on MRI findings in such patients. We present the youngest patient ever reported, and
discuss the important differences between fibrocartilaginous embolus and acute myelitis of childhood. A 6-year-old girl with
a history of back pain presented with sudden-onset nontraumatic paraplegia, with a clinical anterior spinal artery syndrome.
Initial MRI scan revealed intervertebral disc disease at L1–2 and an incidental thoracic syrinx, but no cause for her acute-onset
paraplegia was identified. Cerebrospinal fluid and other investigations were all negative. Sequential MRI scans revealed development
of spinal cord expansion from T10 to the conus medullaris, with increased cord signal in the anterior aspect of the spinal
cord. The intervertebral disc disease was unchanged. The imaging and clinical findings were caused by fibrocartilaginous embolus,
which meant there was no need for spinal cord biopsy. The report describes the clinical and imaging criteria for diagnosis
of fibrocartilaginous embolus, highlighting the case for avoiding an unnecessary biopsy. The clinical pattern in the paediatric
group is discussed, with features differentiating it from acute myelitis of childhood.
