简要总结
To prevent thromboembolic complications, the embolization procedure is performed under prophylactic unfractionated heparin, the efficacy of which is monitored by point-of- care testing according to international guidelines. However, these guidelines are based on limited scientific evidence and the ideal level of anticoagulation required has not been precisely defined. Furthermore, the correlation between the point-of- care tests used at Amiens University Hospital and the reference methods used in the laboratory varies considerably according to the available literature.
详细描述
Since the beginning of the 2000s, the reference treatment for the management of aneurysmal subarachnoid haemorrhage consists of interventional neuroradiology with coil embolization of the aneurysm. Although ensuring a better neurological prognosis than neurosurgical clipping, interventional neuroradiology exposes the patient to various risks: thromboembolic complications during or after embolization and re-rupture of the aneurysm during embolization. To prevent thromboembolic complications, the embolization procedure is performed under prophylactic unfractionated heparin, the efficacy of which is monitored by point-of- care testing according to international guidelines. However, these guidelines are based on limited scientific evidence and the ideal level of anticoagulation required has not been precisely defined. Furthermore, the correlation between the point-of- care tests used at Amiens University Hospital and the reference methods used in the laboratory varies considerably according to the available literature.
