Aneurysm of the common carotid artery is uncommon. In surgery for carotid aneurysm there is the risk of endangering cerebral circulation during the period of arterial occlusion necessary for the resection. Therefore a method which will allow adequate cerebral circulation during carotid artery anastomisis is obviously to be desired. A case of aneurysm of the common carotid artery is presented in which the aneurysm was partially resected and the artery was reconstructed by end to end anastomosis. while cerebral circulation was maintained by an internal polyethylene shunt. The occurrence of this aneurysm was associated with a chronic stasis ulcer of the left fore leg. On this basis the aneurysm was thought to be of mycotic origin though this has not been proved histologically or by laboratory methods. The literature on aneurysm of the carotid artery is briefly reviewed.

A numerical technique is employed to simulate the flow patterns in the human carotid artery and a phantom of the carotid artery made of acrylic material is used to observe the flow phenomena in the carotid artery. For numerical analysis the idealized geometric shape of the carotid artery is constructed to portray the phantom. Steady momentum equation is solved by the finite element method and the numerical results are compared with the results of MRA and color Doppler images.

We report a case of spontaneous right carotid-cavernous fistula (CCF) in a proximal segment of persistent primitive trigeminal artery (PPTA) and combined vascular anomalies such as left duplicated hypoplastic proximal posterior cerebral arteries and a variation of anterior choroidal artery supplying temporal and occipital lobe. A 45-year-old male presented with progressive right exophthalmos, diplopia, and ocular pain. With manual compression of the internal carotid artery, a cerebral angiography revealed a right CCF from a PPTA. Treatment involved the placement of detachable non-fibered and fibered coils, and use of a hyperglide balloon to protect against coil herniation into the internal carotid artery. A final angiograph revealed complete occlusion of PPTA resulted in no contrast filling of CCF.

Various branch anomalies of the aortic arch have been reported, but cases with separate origins of the internal and external carotid arteries with combined direct aortic arch origin of the left vertebral artery are extremely rare. Herein, we present a rare case of aplasia of the left common carotid artery with separate origins of the ipsilateral internal and external carotid arteries and vertebral artery from the aortic arch in a 10-year-old girl. In addition, we review the embryological development and clinical implications of these anatomical variations.

Extracranial carotid artery dissection may manifest as arterial stenosis or occlusion, or as dissecting aneurysm formation. Anticoagulation and/or antiplatelet therapy is the first-line treatment, but because it is effective and less invasive than other procedures, endovascular treatment of carotid artery dissection has recently attracted interest. We encountered two consecutive cases of trauma-related extracranial internal carotid artery dissection, one in the suprabulbar portion and one in the subpetrosal portion. We managed the patient with suprabulbar dissection using a self-expandable metallic stent and managed the patient with subpetrosal dissection using a balloon-expandable metallic stent. In both patients the dissecting aneurysm disappeared, and at follow-up improved luminal patency was observed.

Purpose : This study aimed to investigate the luminal stenosis of the internal carotid artery with calcification detected on panoramic radiographs. Materials and Methods : This study used fifty carotid arteries of 36 dental patients whose panoramic radiograph and computed tomography angiography (CTA) revealed the presence of carotid artery calcification. A neuroradiologist interpreted CTA to determine the degree of stenosis of the internal carotid arteries. The degree of stenosis was stratified in four stages; normal (no stenosis), mild stenosis (1-49%), moderate stenosis (50-69%) and severe stenosis (70-99%). Results : Among the fifty carotid arteries with calcification detected on both panoramic radiography and CTA, 20 carotid arteries (40%) were normal, 29 carotid arteries (18%) had mild stenosis, 1 carotid artery (2%) had moderate stenosis, and there was none with severe stenosis. Conclusion : Sixty percent of the carotid arteries with calcification detected on both panoramic radiography and CTA had internal luminal stenosis, and two percent had moderate stenosis. When carotid atheroma is detected on panoramic radiograph, it is possible that the dental patient has luminal stenosis of the internal carotid artery.

Background: The purpose of this study was to identify the effects of the blood flow on carotid and vertebral artery during the forward shift on head. Methods: A 20-year female healthy subject participated in this study. This study was set up the forward shift on head at the 3cm and 6cm in a shoulder midline (acromion). Measurement method were using duplex ultrasound with colour doppler imaging for the blood flow on carotid and vertebral artery. Results: Carotid artery was increased the blood flow and vertebral artery was decreased the blood flow during forward shift on head. Conclusions: These findings suggest that carotid and vertebral artery changes to the blood flow during forward shift on head. Therefore, we should be consider that hemodynamic factor when apply to the therapeutic exercise for patients of forward head posture.

Comprehensive understanding of the variations in the branching of the external carotid artery (ECA) is essential to minimizing vascular complications during cranio-facial and neck surgical procedures. We demonstrate a rare case of unusual branching of ECAs in both carotid triangles and anomalous origin of the left ascending pharyngeal artery (APA) during dissection of embalmed cadaver. The right and left common carotid arteries (CCA) bifurcated at the level of the upper border of the thyroid cartilage. The right superior thyroid artery (STA) originated anterior to the carotid bifurcation (CB), while the left STA originated from the anterior aspect of the left CCA. The right ECA trifurcated into linguofacial trunk, APA, and distal ECA, 15.7 mm from CB. On the left side, lingual artery and APA arose as a short common linguopharyngeal trunk, 1.9 mm from CB. The left facial and occipital arteries originated anteromedially and posteriorly at the same level.

We describe a case of intracranial carotid artery occlusion due to penetrating craniofacial injury by high velocity foreign body that was relieved by decompressive surgery. A 46-year-old man presented with a penetrating wound to his face. A piece of an electric angular grinder disc became lodged in the anterior skull base. Computed tomography revealed that the disc had penetrated the unilateral paraclinoid and suprasellar areas without flow of the intracranial carotid artery on the lesion side. The cavernous sinus was also compromised. Removal of the anterior clinoid process reopened the carotid blood flow, and the injection of glue into the cavernous sinus restored complete hemostasis during extraction of the fragment from the face. Digital subtraction angiography revealed complete recanalization of the carotid artery without any evidence of dissection. Accurate diagnosis regarding the extent of the compromised structures and urgent decompressive surgery with adequate hemostasis minimized the severity of penetrating damage in our patient.

The complications of deep neck infection have become much less common in the antibiotic era. The vascular complications of deep neck infection can have devasting consequences. Most commonly, the internal carotid artery is involved, although the common carotid and external carotid artery can also be affected.0 the cases of patients with a protracted course, recurrent bleeding, cranial neuropathies, or trismus, the presence of vascular complications must be considered. Appropriate imaging should be carried out to allow the localization of the infection and ascertain the status of the vessels in the neck The vascular structures can be imaged with duplex doppler or color doppler flow ultrasound to see the flow between the mass and vessels. Also angiography plays a key role in the diagnosis and management of vascular complication of deep neck infection. Prompt diagnosis and treatment of these patients is necessary to prevent significant hemmorrhagic complications. We experienced a case of pseudoaneurysm of the common carotid artery secondary to deep neck infection treated successfully with surgical excision in 45-year-old-male.
