Antegrade internal carotid artery collateral flow and cerebral blood flow in patients with common carotid artery occlusion.

Objectives: To determine the incidence of antegrade internal carotid artery collateral flow in patients with common carotid artery occlusion, which artery supplies blood to the internal carotid artery, and whether the flow affects regional cerebral blood flow in the middle cerebral artery territory.

Methods: We determined the incidence of antegrade internal carotid artery collateral flow and identified its arterial origins using carotid sonography in 10 patients with common carotid artery occlusion and evaluated middle cerebral artery territory regional cerebral blood flow by single-photon emission computed tomography in these patients and 30 age- and sex-matched patients with internal carotid artery occlusion.

Results: Six (60%) of the 10 patients with common carotid artery occlusion had antegrade internal carotid artery collateral flow, which was supplied through the carotid bifurcation from retrograde flow of the external carotid artery in 5 and by a small artery directly into the internal carotid artery in 1.

Conclusion: A wide variety of pulmonary conditions present imaging features that mimic those of primary lung cancers and are difficult to differentiate from cancer.

[The clinical effect of combination therapy for oral cancer with S-1, superselective intra-arterial chemotherapy, and radiation therapy].

Combination therapy with S-1, superselective intra-arterial infusion of CBDCA and radiation therapy has been used to treat patients with oral cancer since 2005. In this study, the histopathological effects and toxicities following concurrent chemoradiotherapy were examined. The subjects consisted of 15 patients (10 men and 5 women) who were treated with S-1 (60-80 mg/day, 4 weeks), superselective intra-arterial infusion of CBDCA (300 mg/body) and radiation therapy (total dose 30-36 Gy) in our department from 2005 to 2009.

Histopathological features with angiographic correlates of internal carotid artery pseudo-occlusion: impact of plaque compositions. Clinical article.

Object: This study describes clinicopathological characteristics of pseudo-occlusion of the internal carotid artery with regard to its possible mechanisms.

Methods: The authors retrospectively reviewed 17 patients with pseudo-occlusion and 23 with high-grade stenosis (North American Symptomatic Carotid Endarterectomy Trial criteria ≥ 90%, but no collapsed distal internal carotid artery) who underwent carotid endarterectomy. Atherosclerotic risk factors, clinical presentation, angiographic findings, and histological features of plaque obtained from the carotid endarterectomy were investigated and comparisons were made between groups.

Outcomes associated with carotid pseudo-occlusion.

Purpose: We tested the hypothesis that patients with carotid pseudo-occlusion (PO) have a different prognosis from those with carotid artery stenosis (CS) without PO.

Materials And Methods: 500 patients were examined for CS by cerebral angiography; those with severe CS ≥ 70% (CS group) or with PO (PO group) were enrolled in this study. The primary endpoint was defined as the combined endpoint of the occurrence of stroke, myocardial infarction, or death.

Prognosis of medical treatment for Japanese patients with carotid stenosis.

Purpose: This study was designed to determine whether, among Japanese patients receiving medical treatment for carotid stenosis, symptomatic carotid stenosis was more strongly associated with subsequent neurological events than asymptomatic carotid stenosis.

Methods: We consecutively registered Japanese patients with carotid stenosis of 50% or more as evaluated by digital subtraction angiography who were treated medically. We reviewed medical records regarding previous neurological events as well as other stroke risk factors and underlying diseases at admission.

Correlation between the degree of left subclavian artery stenosis and the left vertebral artery waveform by pulse Doppler ultrasonography.

Background: Development of retrograde blood flow may be observed in the vertebral artery and is associated with progressive ipsilateral proximal subclavian or innominate artery stenosis. The subclavian steal phenomenon is more prevalent in the left subclavian artery (LSA). The purpose of this study was to analyze the correlation between the degree of LSA stenosis and pulse Doppler waveforms of the left vertebral artery (LVA).

[Combination of percutaneous balloon angioplasty and aggressive medical intervention improves symptomatic basilar artery stenosis with a tortuous access route: case report].

Unlabelled: The prognosis of symptomatic intracranial artery stenosis (SIAS) by medical treatment is poor. Percutaneous balloon angioplasty (PTA) or stenting is effective for SIAS. However, recently, aggressive medical intervention (AMI) has progressed and some drugs have been reported to improve stenosis or prevent the progression of stenosis.

Long-term results of medical and surgical therapy for Japanese patients with moderate carotid stenosis.

To clarify the efficacy of medication versus carotid endarterectomy (CEA), we investigated cardiovascular events and outcomes in Japanese patients with moderate carotid stenosis. We consecutively registered patients with significant carotid stenosis (50%-79%) measured by digital subtraction angiography (DSA) over 10 years and compared the incidences of stroke, myocardial infarction, and death between treatment groups (surgical group vs medical group). Of 406 registered patients, 163 (108 treated surgically and 55 treated medically) with moderate carotid stenosis were analyzed.

[A case of parental artery occlusion for a non-ruptured giant thrombosed aneurysm at the right vertebral artery using a goose neck snare to hold a guiding catheter].

The stabilization of a guiding catheter is one of the important factors for achieving successful endovascular treatments. However, obtaining sufficient stabilization is sometimes difficult due to the tortuousity of the approach route. A goose neck snare is useful not only for the retrieval of intravascular foreign bodies but also for holding a guiding catheter.

Angiographic characteristics of radiation-induced carotid arterial stenosis.

Purpose: This study aimed to clarify the angiographic characteristics of radiation-induced carotid stenosis.

Methods: We evaluated 11 carotid arteries of patients after radiotherapy (radiotherapy group) and 26 carotid arteries of age- and gender-matched patients without a history of radiotherapy (control group). All patients had carotid stenosis detected by digital subtraction angiography (DSA).
