Objectives : To determine the effects on blood flow of vertebrobasal vascular system in cerebral infarction, Methods : We altered 33 normal patients and 12 patients who were diagnosed cerebral infarction on Rt. middle cerebral artery(MCA) region and 8 patients who were diagnosed cerebral infarction on Lt, MCA region, and measured the mean velocity, systolic to diastolic rate(SD rate), asymmetrical index(A/I) by TCD. Results : The mean velocity of posterior cerebral artery(PCA), vertebral artery was increased in same direction as infarcted site and the mean velocity of basal artery was more increased than control, and the SD rate of PCA, vertebral artery, basal artery was larger than control. The A/l of PCA, vertebral artery was revealed that mean velocity of vertebrobasal vascular system is increase the same direction as infarcted area. Conclusion : TCD examination within 7 days(acute stage) after stroke can help to predict the infarcted direction.

When a tear occurs in one of the major cervicocerebral arteries and allows blood to enter the wall of the artery and split its layers, the result is either stenosis or aneurysmal dilatation of the vessel. Vertebral artery dissection (VAD) is an infrequent occurrence but is a leading cause of stroke in young and otherwise healthy patients. This article discusses recent developments in understanding of the epidemiology and pathogenesis of VAD and the various clinical manifestations, methods of diagnosis, and approaches to treatment.

With the exception of gun shot wound, the incidence of penetrating injury of face and neck areas nonorganic foreign bodies is relative low. But the diagnostic evaluation and therapeutic management of penetrating facial wounds need careful decision, when the anatomic proximity of the major vessels and nerve is considered. Penetrating facial trauma with concomitant vascular injury present challenging problems, the immediate complication of this vascular injury are severe bleeding, hematoma formation, shock, obstruction of airway. The vascular injury is conformed by angiography. In this report, a industrial tool(long tack) fired by explosive air is penetrated into face and to neck. In angiograms penetrating injury of the vertebral artery is detected. We performed the embolization of the vertebral artery with coils and manual removal of the foreign body without any complication was followed.

The purpose of this paper is to report the patient with lateral medullary syndrome due to occlusion of vertebral artery who was improved by oriental medical treatment. The patient was admitted on May 15, 2009 and remained until May 29, 2009. He was treated with herbal medicine, acupuncture, moxibustion, cupping and physical therapy. After the treatment, the symptoms(vertigo, diplopia, gait ataxia, sensory loss numbness, Horner's syndrome, etc) improved. This result suggests that oriental medicine can be an effective treatment for a patient with lateral medullary syndrome due to occlusion of vertebral artery. But more clinical case reports are needed.

Recently we experienced a case of Takayasu`s arteritis involving the major aortic branches. A 30 year-old female patient admitted with the complaints of dizziness, visual disturbance, headache and tingling sensation of upper extremities. Aortogram revealed nearly complete obstruction of the origin site of both common carotid arteries and right vertebral artery, and irregular luminal narrowing of the origin site of innominate artery and left subclavian artery, but opacification of right subclavian artery and left vertebral artery. Successful surgical treatment was accomplished with a bypass from the ascending aorta to the left common carotid artery using a tube graft. The left subclavian artery and right axillary artery were revascularized distal to the stenosis with tube grafts that extended from the aortic graft. Postoperative complications were atelectasis, lymph leakage and left phrenic nerve palsy. She discharged uneventually at postoperative 22 days and most of symptoms were relieved.

Objectives : CHUNA therapy that removes compression of dislocated vertebral bones has positive effect, but sometimes improper CHUNA manual therapy may give rise to negative effect. The aim of this study is to make sure that cervical CHUNA manual therapy give positive effect or negative effect to the blood flow velocity of vertebral artery(VA) and basilar artery(BA) by Trancranial Doppler sonography(TCD). Methods : We performed TCD study on 20patients(male 5, female 15, mean ages 38.5 years) with diagnosis like cervical movement related disorder, headache or dizziness. After we measured mean blood flow velocity(Vm) of VA and BA before cervical CHUNA therapy(Pre-CCT) and after cervical CHUNA therapy(Post-CCT), statistically evaluated the results. Results: The patients received cervical CHUNA therapy for TA sequel, HIVD of cervical spine, headache, dizziness, neck stiffness etc. VA Vm was $31.9{\pm}8.0cm/sec$ before CHUNA therapy, but significantly increased $35.0{\pm}8.7cm/sec$ after CHUNA therapy (p < 0.05). But, there was no significant variation of BA Vm between $41.8{\pm}7.5cm/sec$ Pre-CCT and $41.2{\pm}8.5cm/sec$ Post-CCT(p>0.05). Though VA Vm slightly increased after CHUNA therapy in normal range group, there was no significant variation between VA Vm Pre-CCT and VA Vm Post~CCT. In VA Vm decrease group, VA Vm significantly increased after CHUNA therapy(p<0.05). But, there was no significant variation of BA Vm between Pre-CCT and Post-CCT in BA Vm normal range group and BA Vm decrease group(p>0.05). Conclusions: These findings suggest that cervical CHUNA manual therapy have positive effect on blood flow velocity of VA and BA.

The safety and feasibility of simple coil embolization and stent deployment for the treatment of posterior inferior cerebellar artery (PICA) aneurysms, as well as their radiologic and clinical results, have not been adequately understood. Especially, if dissecting aneurysm of proximal PICA is associated with small caliber PICA and stenosis of ipsilateral vertebral artery orifice (VAO), endovascular coiling with saving of PICA is not always easy. This 64-year-old man presented with subarachnoid hemorrhage due to a ruptured dissecting aneurysm of left proximal PICA. The aneurysm was irregularly fusiform in nature with a shallow PICA orifice (1.4 mm) and narrow caliber (0.9-1.5 mm). Moreover, the ipsilateral VAO showed severe stenosis (1.8 mm). We performed bifemoral puncture and chose additional route from right vertebral artery to left vertebrobasilar junction for retrograde approach and deployment of LVIS Jr. intraluminal support at proximal PICA. And then, the antegrade approach and coiling of aneurysm was done. Despite of transient thrombus of PICA, the aneurysm was successfully secured with preservation of whole PICA course. For preservation of narrow PICA with ipsilateral VAO stenosis, the contralateral approach and deployment of LVIS Jr. intraluminal support may be considered.

The management of penetrating zone II neck injuries without hard signs of vascular injury has been controversial. The controversy lies between mandatory exploration and a selective approach to the management of theses injuries. Authors that advocate mandatory exploration state its low complication rate and high sensitivity in support of this approach. Surgeons in support of selective management argue selective management has comparable efficacy with lower morbidity in comparison with mandatory exploration. Recently we experienced a case of stab wound near vertebral artery and operatively explored, therefore we report a case along with review of literature.
