However, the Casson equation agrees well only when the shear rate is less than 10 s?1. The flow field of the carotid bifurcation usually covers a wide range of shear rate. We therefore believe that it may not be sufficient to describe the property of blood only using the Casson equation in the whole flow field of the carotid bifurcation.

然而Casson模型只有在低切变率条件下才与血液吻合的较好，而在颈动脉分岔血管中切变率值的分布范围却很广，因此，我们有理由认为，在整个颈动脉分岔血管流场中均采用Casson模型来模拟血液的本构关系是不够的。

Methods: Fresh saphena rings were sudied in organ chamber after incubating with Krebs-Henseleit bicarbonate solutions, FWM, KH with 0.1mmol/L NCR, FWM with 0.1mmol/L NCR at 37℃ for 1 hour. Precontraction induced by prostaglandin F2 (U4661930nmol/L) and endothelium-dependent relaxation induced by calcium ionophore A23187 l0^(-10~l0^(-6) mol/L were measured in the presence of indomethacin (7μmol/L) and LNNA (300μmol/L). Result: No significant changes were found in the 4 groups under the light microscope.

该书共126章，内容涉及心血管疾病基础、无创影像学、电生理学、心脏瓣膜病、主动脉和外周血管疾病、冠状动脉疾病危险因素、心肌梗死、心脏和心包以及肺循环疾病、心肌病和心力衰竭、心脏药理学、有创及介入心脏病学等11个部分，包括1400幅图，其中483幅为彩色照片，涵盖电生理描记图、血管造影图像、心脏缺损的放射图谱以及血流动力学描记图等。

Firstly, the establishment of model requires sophisticated neurointerventional techniques and costly interventional materials(sacculus, minikin circlip ring, endovascular electrocoagulation), it not only consumed time but also increased the resesrch expense ; Secondly, although the Massoud model is the first successful model that contain the nidus, but it is far from mimicking the high-flow fistulae frequently observed in a brain AVM; Thirdly, the rapid spontaneous thrombosis result in fistula occlusion in a short time;Fouthly, the model's natural course and the long–term patency of fistula are unclear;Currently the model is only used for the short-term research.

但Massoud模型目前存在以下主要缺点：第一，模型的建立需要复杂的神经介入技术和昂贵的介入材料(球囊、微弹簧圈、血管内电凝等)，操作费时，又大大增加了研究费用；第二，Massoud模型虽然首次具备了畸形血管团，但它远不是我们临床上常见的含有高流量动静脉瘘的脑AVM；第三，颈动静脉吻合口自发性血栓形成进而导致引流静脉闭塞的机率很高；第四，Massoud模型的长期自然过程和动静脉吻合口的长期通畅性尚不清楚，目前仅仅作为急性期模型。
