Pediatric intracranial aneurysms—clinical characteristics and outcome of surgical treatment

Object Intracranial aneurysms are rare in children and have different epidemiological, clinical, and morphological characteristics and outcome from those in adults. Materials and methods We analyzed demographic, clinical, radiologic features, treatment, and outcome in 55 patients <18 years of age, treated from Jan 1995 through December 2005. Results Intracranial aneurysms in children below 18 years constituted 4% of all intracranial aneurysms. Internal Carotid artery (ICA) bifurcation was the commonest location. About half of the aneurysms were complex. Three-fourth of the patients required surgical treatment. Two patients died, constituting 5% mortality. Two patients (5%) had poor outcome, whereas the majority (90%) had a favorable outcome. Conclusions Pediatric aneurysms have male predominance, higher incidence of clinical features of mass effect or seizures, high incidence of large, traumatic/mycotic aneurysms, associated illnesses and ICH/IVH and hydrocephalus, better Hunt and Hess grades at presentation, ICA bifurcation as the commonest site, and better outcome than their adult counterparts.     

Pediatric cerebellar hemorrhages

Cerebellar hemorrhage is a devastating condition with morbidity and mortality related not only to the etiology of the hemorrhage, but also to the timing of the intervention. Sixteen consecutive pediatric patients with acute cerebellar hemorrhages are presented: 6 had vascular abnormalities, 3 had tumors, and 2 had hemorrhages of unknown etiology. Thirteen of the 16 patients survived with only 1 of the 13 having persistent vegetative state as a neurologic outcome. Six of 8 patients presenting in a moribund condition had good outcomes, and 3 of 4 patients presenting with fixed and dilated pupils also had good outcomes. Thus, in contrast to adults, rapid evaluation by CT scanning, followed by the judicious use of ventricular drainage and prompt surgical treatment, have resulted in favorable outcomes in pediatric patients despite their poor clinical presentations. None of the neonates having cerebellar hemorrhages required surgical intervention; their courses could be followed clinically and with transfontanel ultrasound.Presented as a poster at the 14th Congress of the European Society for Paediatric Neurosurgery, Lyon, France, 21–23 September 1994, and the XXII Annual Meeting of the International Society for Pediatric Neurosurgery, Birmingham, UK, 25–28 September 1994     

Significance of beaten copper appearance on skull radiographs in children with isolated sagittal synostosis

Aims and Objectives The significance of beaten copper appearance (BCA) on skull radiographs in children following surgery for isolated sagittal craniosynostosis has not been studied. This study was designed to look for any correlation between BCA and symptoms suggestive of intracranial hypertension in this group of patients. Materials and Methods Forty-eight consecutive children, who were operated for isolated sagittal synostosis from1987 to 2000 and had postoperative skull radiographs, were included. Patients were divided into: (a) BCA group (n = 20), consisting of children who had beaten copper appearance on skull radiographs at last follow up, and (b) Non-BCA group (n = 28), consisting of children who did not have this finding. Records were reviewed to look for symptoms suggestive of intracranial hypertension, such as headache, head banging, and irritability. Results Median age at surgery was 4.8 months for BCA group and 4 months for the non-BCA group. Follow up ranged from 4 to 156 months with a mean of 36.2 months. Total of 28.6% (n = 6) of the children with follow up radiographs done at ≤18 months of age had BCA. The incidence of BCA increased to 83.3% in children with skull radiographs performed after 48 months of age. In 18 (90%) children, the BCA was ‘diffuse’ with 5 (25%) children having the maximum possible score of 8. In the BCA group, 45% (n = 9) had symptoms compared to 10.7% (n = 3) in the control group (p = 0.0068). Conclusions This study suggests a significant number of children with BCA on radiographs develop symptoms suggestive of raised ICP following surgical treatment in infancy and prolonged follow up may be warranted in this group of patients.     

口服法小肠气钡双对比造影对小肠疾病的影像诊断

目的:探讨口服法小肠双对比造影检查及病变表现特点。方法:辅以高、低张药物,口服80%(w/v)硫酸钡200ml加经肛门逆行注入空气2000ml进行小肠双对比造影检查,显示双对比小肠影像。结果:147次小肠造影检查中118例成功地用该方法进行小肠双对比造影检查,成功率80.27%,年龄14岁至69岁,平均34.3岁。118例中阳性32例,阳性显现率27.12%,病理证实的25例,占阳性病例的78.13%。不能应用高、低张药物和逆行注气失败的共29例,占19.73%。小肠肿瘤、Crohn's病、Meckel's憩室和回肠末段淋巴滤泡增生症小肠疾病的双对比影像具有特征性表现。结论:(1)此法小肠双对比造影检查简便易行,适合各类有电视X线机的放射科开展。(2)小肠病变在双对比影像上表现特征明显,易于诊断。(3)不能应用高、低张药物和肛门括约肌松弛的患者用此法检查将受到限制。     

经肝动脉介入治疗并发胆囊坏死(2例报告并文献复习)

目的 :探讨经肝动脉介入治疗并发胆囊坏死的发生原因和防治措施。方法 :报告 2例经肝动脉介入治疗并发胆囊坏死的病例 ,均经手术病理证实。并结合文献资料分析这一并发症发生的机率、原因 ,以及为了减少并发症的发生需要注意的一些问题。结果 :近 8年来我院共做经肝动脉介入治疗 6 80例次 ,并发胆囊坏死 2例 (0 3% )。其发生原因是多方面的。超选择插管不到位是该并发症发生的主要原因。结论 :胆囊坏死是经肝动脉介入治疗比较常见的严重并发症之一 ,在今后工作中应引起足够的重视 ,尤其对肝血管瘤的介入治疗更应慎重 ,使这一并发症的发生率降至最低限度。
