Asymptomatic carotid kinking
ABSTRACT Doppler sonography has gained considerable recognition as a noninvasive method of detecting carotid artery disease, and power Doppler sonography achieves good color-filling of all the examined vessels. Dolichoarterial disease of the internal carotid artery occurs in 10-25% of the population; these alterations are characterized by atypical elongation of the vessel, which predisposes it to tortuosity, coiling, and kinking, which is the most frequent morphologic anomaly and is characterized by sharp angulation (single and double Z-shaped). A patient with double Z-shaped angulation (kinking) of the left internal carotid artery was incidentally diagnosed in an asymptomatic state because of the broad use of these noninvasive investigations.

- "Knowing the normal anatomy and also its anomalies is important in preventing these complications. A wide variety of carotid artery anomalies or anatomic variations which include aplasia, agenesis, tortuosity, hypoplasia, trifurcation, kinked, curved, anomalous origin, independent origins, nonbifurcation cervical carotid artery, and aberrant artery were reported        . "
ABSTRACT: Lower cervical bifurcation of cervical common carotid artery (CCA) is a very rarely encountered anatomic variation. Knowing the normal vascular anatomy and also its anomalies is important in preventing the vascular complications. Ill-defined vascular anomalies may lead to massive hemorrhage and eventually death during head and neck surgery. Imaging of the neck by magnetic resonance Imaging (MRI), CT, or angiography is helpful for diagnosis. We present a 62-year-old male patient diagnosed with laryngeal carcinoma who had been treated. His MRI revealed bilateral low-level bifurcation of the cervical common carotid arteries as well as tumor localization and its boundaries. Total laryngectomy and right selective neck dissection was performed to the patient with the diagnosis of squamous cell carcinoma of the larynx. During the neck dissection, carotid bifurcation was detected in common border of Level 3 and Level 4 of the neck.07/2013; 2013:894804. DOI:10.1155/2013/894804

ABSTRACT: Several specialists use three-dimensional (3D) ultrasound as adjuvant imaging technique in their clinical practice. It has been applied to study carotid plaque morphology, surface and volume during atherosclerosis progression. Nonetheless, no papers have so far described the use of this technique in conditions different than carotid stenosis, such as bifurcation anatomy changes of the caliber and vessel course modifications. Patients admitted to our ultrasound laboratory for vascular screening were submitted to standard carotid duplex and to 3D ultrasound reconstruction of the carotid bifurcation. Forty normal subjects, 7 patients with caliber alterations (4 carotid bulb ectasia and 3 internal carotid lumen narrowing), 45 patients with course variations (tortuosities and kinking) and 35 patients with internal carotid artery stenosis of various degrees have been investigated. 3D ultrasound is a feasible technique. It can improve carotid axis imaging through a better presentation of caliber variations and vessel course 'at a glance'. 3D ultrasound from the inward flow can provide imaging of the stenosis, but stenosis quantification should always take into account the assessment of plaque morphology and vessel wall.European Neurology 05/2011; 65(6):309-16.
