Collateral Pathway

For evaluation of the hemodynamics of the collateral circulation to the ligated external carotid artery (ECA) region, we measured the blood flow direction and volume in branches of the ECA in patients with unilateral carotid artery ligation before and during digital suppression of the common carotid artery (CCA) on the ligated and nonligated sides with color Doppler imaging and angiography. The main collateral pathway to the ligated ECA region was the ipsilateral occipital artery through Richter's anastomosis from the vertebral artery in the case of unilateral ECA ligation, and was the contralateral carotid artery in the case of unilateral CCA, ECA, and internal carotid artery resection. The superior and inferior labial arteries were important as the collateral pathway from the contralateral ECA.

Benign Mass

A carotid body tumor is typically a benign mass and can have a low malignant potential. It can grow in between, attach to, or surround the internal carotid artery and external carotid artery in the neck. If this mass grows too big, it can compress the two arteries, causing problems in getting blood flow to the brain. The purpose for this sonography examination was to evaluate a patient with the following symptoms: dizziness, facial nerve injury, and sensorineural hearing loss. The carotid body tumor is a highly vascular tumor. This sonography examination provides a good opportunity to teach the importance of the use of color Doppler and proper documentation of this pathology that is often incorrectly documented with improper settings. This case reviews a 69-year-old Caucasian male with a carotid body tumor. The sonographic features, prevalence, common symptoms, prognosis, and treatments of the carotid body tumor are reviewed.

Artery Detection

Carotid duplex sonography is a useful method for evaluation of dural arteriovenous fistulas. The resistance index of the external carotid artery has been reported to correlate with the efficacy of treatment and recurrence or aggravation of dural arteriovenous fistulas. Herein, we describe a case of dural arteriovenous fistulas mainly supplied by the occipital artery and show that the resistance index of the occipital artery was more sensitive than that of the external carotid artery. To the best of our knowledge, this is the first report to describe the feasibility of occipital artery detection by carotid duplex sonography and clinical application of the resistance index of the occipital artery for dural arteriovenous fistulas.

Meningeal Artery

We describe a rare case of having both symptomatic ipsilateral retinal embolization and asymptomatic cerebellar embolization occurring after carotid stenting with use of distal protect device. In this case, external carotid angiograms revealed accessory meningeal artery-ophthalmic artery and occipital artery-vertebral artery anastomoses. This case suggested that the protection for external carotid artery should be considered during carotid stenting to avoid retinal embolization and cerebellar or cerebral embolization in cases showing angiographical anastomoses between external carotid artery and ophthalmic artery or intracranial arteries.

AbstractThe surgical management of intractable epistaxis by external carotid artery ligation may become complicated if there is a high bifurcation of the common carotid artery. Occlusion of the bleeding vessels by catheter embolization is described in a patient in whom exploratio n of the neck had failed to locate the external carotid artery.

✓ “Color Doppler energy” (or “power Doppler”), a new color Doppler ultrasound technique that is independent of flow direction and very sensitive to movement, was assessed for its use in the identification of intracranial aneurysms in patients with recent subarachnoid hemorrhage immediately prior to using cerebral angiography. Features that identified aneurysms using this technique included the appearance of abnormal color where no normal artery was expected, abnormal bulging of an artery, and greater “expansibility” of the aneurysm in comparison to an adjacent normal vessel. In this exploratory study, 30 of 33 aneurysms were correctly identified in 35 patients with a good bone window. Color Doppler energy is considerably more sensitive to intracranial blood flow than conventional color Doppler imaging. Color Doppler energy is a useful research tool; if these preliminary results are verified in larger series, in addition to examination for vasospasm, the technique could be used for identification and follow up of aneurysms.

Fluoroscopic Control

✓ A patient undergoing external carotid artery therapeutic embolization for obliteration of a dural arteriovenous malformation suddenly developed a large occipital artery to vertebral artery shunt. A devastating stroke was averted because the appearance of the shunt was observed by fluoroscopy, the embolization was stopped, and the shunt verified on a subsequent angiogram. The risk of external carotid artery embolization without constant fluoroscopic control is emphasized.
