CA0456-CTA Neck
Case ReportHistory
Exam
Prior Study
1. Acute thrombus in Lt. intracranial primary and secondary stem components of the Lt. ICA
2. Early cytogenic edema in both Lt. ACA & MCA territories, likely stroke-age is in the 3-6 hour range.
CT Perfusion
CT perfusion was not obtained
Findings
CTA of the neck
The aorta, the brachiocephalic arteries, the common carotids, the Rt. cervical ICA, the cervical vertebral arteries all are all intrinsically NL.
The left cervical ICA is partially, collapsed just after the carotid sinus, which is an indication of downstream luminal blockade, since there is no high-grade stenosis to account for distal arterial luminal collapse. The high cervical ICA is not included on the Neck CTA
Impression
2. There is unexplained reduced lumen size of the upper Lt. cervical ICA likely secondary to downstream obstruction. However, the neck CTA did not include any of the intracranial/extradural parts of the left ICA.
3. No venous egress obstruction in the major neck veins was evident.
