BACKGROUND
"Kissing carotids" typically involves the lower C4-C6 retropharyngeal space. Here, we describe a case of "kissing carotids" observed at the C1-C2 level in conjunction with basilar invagination (BI).
CASE DESCRIPTION
A 34-year-old-male presented with congenital atlantoaxial dislocation and BI. The initial surgical plan was for a transoral decompression (TOD). However, this approach was abandoned when the preoperative computed tomography angiography (CTA) documented "kissing carotids" lying anteriorly at the C1-C2 level.
CONCLUSION
Obtaining a CTA before performing a TOD for BI is essential to prevent an intraoperative catastrophic hemorrhage due to the laceration of "kissing carotids."
背景
“颈动脉交叉”通常涉及咽后间隙的下颈4-颈6水平。在此，我们描述一例在颈1-颈2水平观察到的“颈动脉交叉”病例，同时伴有基底凹陷（BI）。
病例描述
一名34岁男性，患有先天性寰枢椎脱位和基底凹陷。最初的手术计划是经口减压（TOD）。然而，当术前计算机断层扫描血管造影（CTA）显示颈1-颈2水平前方存在“颈动脉交叉”时，该方法被放弃。
结论
在对基底凹陷进行经口减压之前进行CTA检查对于预防因“颈动脉交叉”撕裂导致的术中灾难性出血至关重要。
