We proceeded to implant a stent from the left ECA to the common carotid artery (CCA). In this way, we dilated the origin of the ECA and jailed the ICA origin. The patient was discharged home after 3days and was asymptomatic at 3- and 12-month follow-up. Endovascular management of CSS...

CT示双侧颈动脉分叉区见边界清楚的实性肿块,静脉注射造影剂时强化均匀,导致颈内动脉(ICA)和颈外动脉(ECA)扩张,肿块大小左侧2.7 ×1.9 ×1.8 cm,右侧1.4 ×0.9 ×0.8 cm。 存在造影剂均匀强化而有别于淋巴结肿物和神经鞘瘤的鉴...
细胞内钙离子(iCa2+)的响应是评估CASR功能的重要指标。研究中,利用Calbryte™ 520荧光探针,研究者测量了突变型CASR对不同浓度梯度的细胞外钙离子(eCa2+)的响应。结果显示,与野生型相比,I554N突变型CASR对eCa2+的增加反应迟钝,...
