  • Compared to the other chemodectoma, aortic body tumors, the carotid body tumor is rarer and more often malignant. In the present case, a 12-year-old, intact female Shih-tzu dog presented to the hospital with a right ventral cervical mass. The mass was diagnosed by immunohistochemical staining with chromogranin A (CgA) as a carotid body tumor. The cervical mass and metastasized lymph node were removed by surgical resection. Because the dog had valvular heart disease, chemotherapy with carboplatin was initiated over 6 months to prevent metastasis and recurrence as an adjunctive treatment. After over two years of management, tumor metastasis and recurrence were not observed until recently. This report shows that proper management and chemotherapy as an adjunctive therapy can treat carotid body tumors in elderly dogs with concurrent heart disease.

  • Congenital absence of the bilateral internal carotid arteries (ICA) is a very rare occurrence. Recognition of this rare anomaly is important, when considering intracranial endovascular interventions in the event of thromboembolic events with revascularization, transsphenoidal surgery, and the surveillance and detection of associated cerebral aneurysms. We report a case of a 25-year-old man who presented with headache since 2 years ago, and was incidentally discovered to have a congenital bilateral absence of ICAs.

  • Penetrated injury of common carotid artery (CCA) is rare and extremely lethal. Carotid artery injury tends to bleed actively and potentially occlude the trachea. It can cause fatal neurological complications. An accurate diagnosis and adequate treatment are very needed to the successful outcome of the penetrating vascular injury in zone 1, 2, and 3 of the neck. Open surgical treatment is more invasive and complicated than endovascular treatment. We experienced a case with penetrating injury in neck zone 2. Here, we report the case successfully treated with endovascular stent graft technique.

  • To determine the utility of spiral computed tomography(CT) in the evaluation of carotid artery stenosis, spiral CT images of 10 patients were compared with both ones of conventional angiography and magnetic resonance(MR) angiography. The severeness of stenosis was determined for each Internal carotid artery on the basis of arterial narrowness : mild stenosis : 40 % or less, moderate stenosis = $40{\sim}70%$, severe stenosis = greater than 70 % of arterial narrowness. The short examination and clear depiction of the arterial lumen In areas of complex or low flow make CT angiography attractive alternative to MR angiography. Spiral CT angiography shows normal and abnormal carotid anatomy well when compared with conventional anglography.

  • Molecular imaging with targeted contrast agents enables tissues to be distinguished by detecting specific cell-surface receptors. In the present study, a ligand-targeted acoustic nanoparticle system is used to identify angioplasty-induced expression of tissue factor by smooth muscle cell within carotid arteries. Pig carotid arteries were overstretched with balloon catheters, treated with tissue factor-targeted or a control nanoparticle system, and imaged with intravascular ultrasound before and after treatment. Tissue factor-targeted emulsion bound and increased the echogenicity and gray-scale levels of overstretched smooth muscle cell within the tunica media, versus no change in contralateral control arteries. Expression of stretch-induced tissue factor in carotid artery media was confirmed by immunohistochemistry. The potential for abnormal thrombogenicity of balloon-injured arteries, as reflected by smooth muscle expression of tissue factor, was imaged using a novel, targeted, nanoparticulate ultrasonic contrast agent.

  • The carotid artery is one of the main vessels supplying blood to the brain. Carotid artery stenosis is mostly caused by atherosclerosis, a disease where cholesterol is deposited in the arterial blood vessels. Tremor refers to rhythmic shaking of a body part. Tremor is a symptom of many diseases, including Parkinson's disease, essential tremor, orthostatic tremor, cerebellar disease, peripheral neuropathy, and alcohol withdrawal. Tremors may be classified as postural, rest, and action tremors. Tremor of a patient with stenosis of the left carotid artery decreased with acupuncture treatment. The acupoints were GB20, TE17, GV8 and GV11. This case shows that the acupuncture treatment is effective against tremor.

  • Aneurysms of the extracranial carotid arteries are relativeley rare in comparison with the total arterial system, but can cause death or a cerebrovascular accident. The treatment of choice is resection of the aneurysm and restoration of arterial continuity. This report describes two cases of extracranial internal carotid arterial aneurysm, which were saccular type. In both cases, the operations were performed under general anesthesia without shunt. The patients were recovered without any neurological sequelae.

  • Blunt carotid artery injury is uncommon, yet not rare. However, it is often underdiagnosed because of inconsistent early symptoms or masking by the presence of coexisting brain and spinal injuries. The delay between the accident and the onset of cerebral ischemic symptoms is variable and has been reported to range from minutes to ten years. However, to our knowledge, there has been no report on a case presented with delayed intracerebral hemorrhage 25months after blunt carotid artery injury. We report on a case with discussion of supporting evidence and possible mechanisms.

  • Direct carotid-cavernous fistula [CCF] is a common post-traumatic disease. However, pseudoaneurysm formation after balloon occlusion is a rare complication. The author present such a case with review of the literature. A 26-year-old man involved in a motor vehicle accident as a driver. Only mild conjunctival injection and minimal exophthalmos on the right eye were noted after trauma. However, angiography revealed a direct CCF and dissection of the proximal intracranial internal carotid artery [ICA]. After first balloon occlusion of the CCF, the patient redeveloped fistula due to early deflation of the balloon. After the second balloon occlusion, pseudoaneurysm and diplopia were developed with the change of balloon position and shape. However, visual symptom spontaneously resolved and pseudoaneurysm was also decreased within 6 months after balloon occlusion.
