Objective: We describe two cases of left carotid artery stenting (CAS) via transbrachial artery approach by using coaxial system with an ASAHI FUBUKI Dilator 6Fr and an ENVOY Simmons 6Fr. Case presentation: Two patients with symptomatic left carotid stenosis were treated with CAS via the transbrachial artery approach. By using coaxial system with an ASAHI FUBUKI Dilator 6Fr 80 cm and an ENVOY Simmons 6Fr 100 cm, an ENVOY Simmons 6Fr was placed into the left common carotid artery (CCA). Next, after a 0.035-inch halfstiff type guidewire was navigated into external carotid artery, an ASAHI FUBUKI Dilator 6Fr alone was advanced into the left CCA. CAS was performed by using distal filter protection method. There was no residual stenosis of the lesion after CAS. Conclusion: A navigation of guiding sheath by using coaxial system with an ASAHI FUBUKI Dilator 6Fr and an ENVOY Simmons 6Fr was effective in left CAS via transbrachial artery approach.
Deformation of plaque in the carotid artery was studied in patients by B-mode ultrasonography. The plaque showed a change in shape due to pulsatile blood flow. Five of the patients had suffered cerebral stroke.There are many risk factors of embolism that can cause stroke, and soft plaque is an important risk factor for cerebral infarction. We coined the term "jellyfish sign" for this unstable deformation pattern of soft plaque. Unstable movement of the plaque suggests that it may contain a soft area and hemorrhage under a thin cap, which might easily cause rupture and artery to artery embolism. B-mode is useful for revealing such high-risk plaque showing the "jellyfish sign".
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
