1 Subarachnoid hemorrhage after carotid artery stenting
Tadeusz Przewlocki, MD, PhD, Piotr Pieniazek, MD, PhD, Anna Kablak-Ziembicka, MD, PhD, Rafal Motyl, MD, PhD, Zbigniew Moczulski, MD, PhD, Wieslawa Tracz, MD, PhD  Journal of Vascular Surgery  Volume 45, Issue 5, Pages (May 2007) DOI: /j.jvs Copyright © 2007 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 Multislice computed tomography angiography. A, the right ICA string-stenosis; B, occlusion of the left ICA. Doppler ultrasound. C, occlusion of the left ICA; D, the right ICA string-stenosis. Transcranial color-coded Doppler of the Willis circle. E, yellow arrow shows patent posterior communicating artery (PCoA) situated between the right middle cerebral artery (RMCA) and the right posterior cerebral artery (RPCA); F, spectrum registered in the PCoA indicates blood flow from the RPCA to the RMCA.

3 Fig 2 Images in the upper raw present TCCD findings: A1, prior to CAS, decreased PSV (62 cm/s) in the right MCA, posterior communicating artery (arrow); B1, after CAS, 2.8-fold PSV increase in the right MCA (PSV-175 cm/s); C1, 2 weeks after CAS, slow decrease of MCA PSV (133 cm/s); D1, 4 weeks after CAS, normalization of the right MCA PSV (92 cm/s) Images in the lower raw present CT findings: A2, prior to CAS, normal CT scan; B2, after CAS, subarachnoid hemorrhage with bilateral hemisphere edema; C2, 2 weeks after CAS, the right hemisphere edema, previously seen blood is absorbed; D2, 4 weeks after CAS, complete lesions’ resolution.

4 Fig 3 Angiography of the right ICA and cerebral arteries. A, B, prior to CAS, soft ulcerated plaque in right ICA causing string-stenosis; impaired cerebral flow. C, D, just after CAS, a good angiographic result after CAS and flow to the right and left middle and anterior cerebral arteries.
