analysis of 92 cases of neonatal intracranial Hemorrhage by transcranial ultrasounography diagnosis
China Practical Medicine, 2010Co-Authors: Liu YingqionAbstract:Objective Transcranial Ultrasound in the diagnosis of intracranial Hemorrhage(Neonates Intracranial Hemorrhage,NIH)clinical features and evaluate its clinical value of screening and early diagnosis of NIH safe and simple method.Methods The clinical manifestations of 156 cases of suspected neonatal NIH for transcranial ultrasound.Results 92 patients had intracranial Hemorrhage ultrasound image change,there is a history of choking,bleeding the most common sites of subependymal Hemorrhage in 38 cases,followed by intraventricular Hemorrhage in 17 cases;have a history of birth trauma,bleeding sites,mainly in the hard Meningeal Hemorrhage in 10 cases,followed by subarachnoid Hemorrhage in 5 cases;no obvious incentive to cause intracranial Hemorrhage,bleeding sites in the subarachnoid space were found in 10 cases,accounting for six cases of cerebral Hemorrhage.Conclusion It's safe,simple,noninvasive,inexpensive,non-radiation damage of transcranial ultrasound for diagnosis of NIH,the advantages for dynamic tracking and observation,especially for NIH were followed up after Hemorrhage,ultrasound is more advantage to the NIH diagnostic ultrasound of great significance can be used as routine screening and follow-up imaging method of choice for NIH.

the value of mri for the diagnosis of Meningeal Hemorrhage during vasospasm
Journal of Neuroradiology, 1999Co-Authors: P Liot, C Oppenheim, Didier Dormont, M Sahel, Alfredo Casasco, Beatrice Marro, Stephane Clemenceau, J Philippon, C MarsaultAbstract:Le diagnostic retrospectif d'hemorragie meningee a la phase subaigue est difficile lorsque l'episode aigu initial est passe inapercu, que l'histoire clinique est trompeuse et que le scanner est normal. Ce diagnostic est encore plus difficile lorsque les patients consultent en periode de vasospasme arteriel, et que le tableau clinique est d'avantage celui d'un accident ischemique que celui d'une hemorragie meningee. Nous rapportons ici deux observations de deficit neurologique focal d'apparition brutale en rapport avec un vasospasme arteriel au decours d'une hemorragie meningee par rupture anevrismale, passee initialement inapercue. Dans les deux cas, le scanner cerebral n'a pas mis en evidence d'hemorragie meningee et l'IRM a ete l'element cle du bilan permettant d'evoquer puis de conclure au diagnostic de spasme apres hemorragie meningee. Les deficits neurologiques ont ete completement regressifs et les anevrismes rapidement exclus. Meme si c'est un diagnostic difficile, il est fondamental en presence d'une lesion ischemique de penser au vasospasme arteriel, afin de mettre en route une therapeutique adaptee, d'eviter les traitements thrombolytiques ou anti-coagulants, et de proteger rapidement le patient d'un resaignement en traitant l'anevrisme responsable du saignement initial.

cerebro Meningeal Hemorrhage secondary to ruptured vascular malformation during pregnancy and post partum
Neurochirurgie, 2000Co-Authors: S Velut, L Vinikoff, Christophe Destrieux, M KakouAbstract:Thirty two new cases of vascular malformations discovered during pregnancy were reviewed in a multicentric retrospective study and compared to the literature. The authors studied both the influence of pregnancy and post-partum on cerebral vascular malformations and the corresponding neurosurgical and obstetrical management. The relative frequencies of arteriovenous malformations (AVMs) and arterial aneurysms (AAs) is the same for pregnant and non-pregnant women. Pregnancy does not increase the risk of first bleeding of vascular malformations but the risk of re-bleeding is increased for AVMs. The bleeding of a vascular malformation is more strongly correlated to age than to parity. The mean maternal age at the time of rupture is greater for AAs than for AVMs, as it is in the general population. The bleeding of a vascular malformations occurs more frequently during the second and third trimesters of pregnancy than in the first one and in the post-partum. Labor and delivery are not great-risk-periods. Management of vascular malformation in pregnant woman is proposed as follow : --a ruptured AA or AVM is managed as it is in non-pregnant woman, whatever the gestational age; no fetal extraction needs to be performed except ed if the rupture occurs at the very end of the pregnancy;--an non-ruptured AVM discovered during pregnancy is treated after delivery; an non-ruptured AVM that never bled before pregnancy is managed in the same way that an non-ruptured AA.

cerebro vascular emergencies cerebral and Meningeal Hemorrhage
Bulletin De L Academie Nationale De Medecine, 2002Co-Authors: Jacques PhilipponAbstract:RESUME L’hemorragie cerebrale n’est pas la forme la plus frequente des accidents vasculaires cerebraux, mais elle en est la plus grave. Son incidence a notablement diminue grâce a une meilleure prise en charge des hypertensions arterielles qui en sont la cause la plus frequente. Le diagnostic a ete transforme par les examens neuroradiologiques modernes, le traitement optimal d’urgence, medical et/ou chirurgical, reste encore l’objet de controverses. Le choix doit prendre en compte l’etat clinique, le volume de l’hemorragie et sa localisation, l’âge du patient. La prise en charge d’urgence en milieu specialise a contribue a ameliorer le pronostic global ; la place et l’interet du traitement chirurgical devraient beneficier d’etudes prospectives pour definir les meilleurs candidats a ce type de traitement. Le probleme est tout different pour l’hemorragie meningee liee a la rupture d’une malformation vasculaire cerebrale ou un traitement rapide est necessaire, qu’il soit chirurgical ou par embolisation.
