OBJECTIVE: With the improvement of surgical techniques, instruments and diagnostic imaging, the aneurysmal surgery could be performed less invasively with less retraction of neural structure and more smaller craniotomy. The authors present a superior orbital rim approach as minimally invasive anterior circulation aneurysm surgery. METHODS: Superior orbital rim approach was performed for the treatment of the anterior circulation aneurysms with or without clinoidectomy. We considered the indications and limitations of this approach and compared this approach with conventional approaches. RESULTS: The operative technique can be used in all cases of anterior circulation aneurysms and could give us excellent results, especially, in internal carotid artery aneurysms. In cases of middle cerebral artery aneurysms, more wide and lateral approaches were used. In general, operation time was shortened and transfusion was not needed. CONCLUSION: The superior orbital rim approach is a good alternative procedure to conventional microsurgical approach in treating anterior circulation aneurysms.

Objective To retrospectively analyze the characteristics of the traumatic rupture of intracranial internal carotid artery in order to provide reference for forensic expertise examination and identification. Methods A total of 11 autopsy cases of traumatic rupture of intracranial internal carotid artery were collected. The gender, age, cause of injury, blood loss on the scene, location of internal carotid artery rupture, hardening degree of the rupture of the wall, brain injury, blood ethanol content and cause of death were also recorded. Results All 11 cases died on the scene, of which 7 died from traffic accidents, 2 falls from height and 2 from bare handed injuries. None of the 11 victims suffered serious head and body surface injury. The internal carotid artery rupture in the 9 cases of traffic injury and fall from height injury occurred in the cavernous segment. In all these cases, there were transverse fractures of the middle cranial fossa with the carotid sulcus involved, and minor intracranial hemorrhage and brain contusion. In 2 cases of bare handed injuries, internal carotid artery rupture occurred in the ophthalmic artery segment, accompanied by fatal intracranial hemorrhage and diffuse axonal injury, but no skull fracture. All 11 cases showed full-thickness rupture of the vessel wall, and the long axis of the wounds was perpendicular to those of the artery. Conclusion The incidence of intracranial internal carotid artery rupture in high-energy trauma events such as traffic accidents and high falls deserves attention. Injuries of the cavernous segment or ophthalmic segment might be more common. The main injury mechanism of intracranial internal carotid artery rupture might be that the blood vessels were pulled and the bone fragments caused damage.

OBJECTIVETo assess the clinical value of transoral carotid ultrasonography (TOCU) in the detection of the blood flow parameters of the distal extracranial internal carotid artery (ICA) in patients with moyamoya disease.

METHODSFourteen patients with the diagnosis of moyamoya disease confirmed by digital subtractive angiography (DSA) underwent examination with conventional carotid ultrasonography of the proximal internal carotid artery (ICA). TOCU was performed to observe the distal extracranial ICA and the internal diameter, peak systolic velocity (PSV) and end-diastolic velocity (EDV) were measured.

RESULTSAll the patients had unilateral moyamoya disease. Compared with the contralateral ICA, distal extracranial ICA showed a significantly reduced internal diameter, PSV and EDV (P<0.05). No significant differences were found in the internal diameter, PSV or EDV between the distal and proximal ICA on the diseased side. The internal diameter of the bilateral common carotid arteries (CCA) was similar, but the PSV and EDV were significantly lower in the contralateral CCA.

CONCLUSIONTOCU can provide information of the blood flow in the distal extracranial ICA to facilitate an accurate diagnosis of moyamoya disease.

OBJECTIVETo evaluate the relationship between coronary artery stenosis and internal carotid artery, vertebral and basilar artery stenosis using computed tomographic angiography.

METHODSThe imaging and clinical data of 84 patients who underwent coronary, head and cervical computed tomographic angiography in our hospital between September 2008 and June 2010 were retrospectively analyzed. Segment stenosis scoring was performed to quantify the degree of stenosis of coronary arteries. The relationship between the segment stenosis scoring and the degree of stenosis for internal carotid artery, vertebral and basilar artery was analyzed.

RESULTThe coronary segment stenosis scores were significantly correlated with the degree of stenosis for internal carotid artery, vertebral and basilar artery (r=0.450 and 0.475,P<0.05) .

CONCLUSIONThe degree of the stenosis of coronary artery is associated with the stenosis of internal carotid artery, vertebral and basilar artery, which can be confirmed by computed tomographic angiography."
