OBJECTIVE: To examine possible etiology and treatment outcomes in 21 patients with glans necrosis following penile prosthesis implantation. METHODS: Glans necrosis typically presented with a dusky glans on first post-operative day following prosthesis implantation. RESULTS: The blood supply to the glans penis consists of the dorsal arteries and the terminal branches of the spongiosal arteries. Using this cohort, we compiled pre-operative comorbidities and adjunctive surgical maneuvers that might compromise glans vascularity leading to glans necrosis...

Blister aneurysms are rare cerebrovascular lesions for which the treatment methods are reviewed here, with a focus on endovascular options. The reported pathogenesis of blister aneurysms varies, and hemodynamic stress, arterial dissection, and arteriosclerotic ulceration have all been described. There is consensus on the excessive fragility of blister aneurysms and their parent vessels, which makes clipping technically difficult. Open surgical treatment is associated with high rates of complications, morbidity, and mortality; endovascular treatment is a promising alternative...

Purpose. To determine the correlations among the mean blur rate (MBR) in the optic nerve head (ONH) shown by laser speckle flowgraphy (LSFG), retinal arteriosclerosis, and the circulation time obtained by fluorescein angiography (FA). Method. We evaluated 118 patients and assessed their time of choroidal flush, arm-to-retina time, and early and late phases of retinal circulation time (RT: sec) obtained by FA. The severity of retinal arteriosclerosis was classified according to the Scheie classification. The MBR values throughout the ONH (MBR-A), in the tissue (MBR-T), and in the vessels (MBR-V) were analyzed...

BACKGROUND: A pathergy reaction is defined as a hyperreactivity of the skin in response to minimal trauma, which is important in the diagnosis of Behçet's disease (BD). However, a pathergy reaction may not be restricted to the skin, and little is known about whether an invasive medical procedure can induce the reaction. Here we present a pathergy reaction induced by renal biopsy, an invasive procedure. CASE PRESENTATION: A 46-year-old man who was diagnosed with IgA vasculitis (IgAV) at the age of 38 was treated with prednisolone and mizoribine...

Contrast-enhanced transoral carotid ultrasonography (CETOCU) is a novel examination modality that is superior to other modalities in the cases of pseudo-occlusion with severe arteriosclerotic stenosis of the distal internal carotid artery (ICA), and is also useful for noninvasively evaluating changes over time in the vessel distal to the stent following carotid artery stenting (CAS). We report a case of a patient who we evaluated with CETOCU for a pseudo-occlusive ICA before and after CAS.

We report a case of ruptured peripheral cerebral aneurysm at abnormal vessels associated with severe stenosis at the middle cerebral artery (MCA). A 66-year-old woman was admitted at our hospital with headache on foot. Computed tomography (CT) showed intracerebral hemorrhage in the left fronto-basal area. Three-dimensional-CT and conventional angiogram revealed abnormal vessels, which were similar to those seen in moyamoya disease, with a small enhancement close to the hematoma. On day 11, subsequent cerebral angiogram demonstrated an aneurysm at the peripheral portion of an abnormal vessel arising from the left A2...

Aberrant pulmonary artery exposed by high-blood pressure over a long period in adult-type pulmonary sequestration can be susceptible to arteriosclerotic change and aneurysmal formation. Dividing this aneurysmal artery has a risk of stump leakage and aneurysm. We herein report a 64-year-old man with an aberrant aneurysm of intralobar pulmonary sequestration. Thoracoscopic resection of the sequestrated lung was performed uneventfully by prior endovascular occlusion of the aberrant aneurysm.

BACKGROUND: The predilection site of non-occlusive mesenteric ischemia is the right-sided colon. Surgical exploration followed by segmental bowel resection and primary anastomosis or ileostomy is recommended, if vascular interventions are not feasible and conservative treatment fails. We assessed the outcome of patients in this life-threatening condition. METHODS: From a prospective database 58 patients with urgent surgery for acute right-sided colonic ischemia without feasible vascular intervention (as a surrogate for non-occlusive mesenteric ischemia) were identified...

BACKGROUND: Carotid arteriosclerosis and sleep apnea are considered as independent risk factors for stroke. Whether sleep apnea mediates severity of carotid stenosis remains unclear. Sleep apnea comprises two pathophysiologic conditions: OSA and central sleep apnea (CSA). Although OSA results from upper airway occlusion, CSA reflects enhanced ventilatory drive mainly due to carotid chemoreceptor dysfunction. METHODS: Ninety-six patients with asymptomatic extracranial carotid stenosis of ≥ 50% underwent polysomnography to (1) determine prevalence and severity of sleep apnea for different degrees of carotid stenosis and (2) analyze associations between OSA and CSA, carotid stenosis severity, and other arteriosclerotic risk factors...

In dialysis access fistulas and grafts, percutaneous transluminal angioplasty (PTA) is frequently followed by restenosis development, which results in repeated periodical re-interventions. The technique of drug-eluting balloon (DEB) angioplasty has shown promising results in the treatment of femoropopliteal arteriosclerotic lesions. In contrast to arteriosclerotic arteries, dialysis access vessels host unfavorable hemodynamics due to the direct conduction of high-pressure fluid into a low-pressure system. Hence, the beneficial effect of DEB angioplasty may be limited in this system...

INTRODUCTION: Retinal artery occlusion (RAO) and non-arteritic anterior ischaemic optic neuropathy (NAION) cause painless vision deterioration and visual field defects. Associations with arteriosclerotic risk factors, hyperhomocysteinaemia, hyperfibrinogenaemia and plaques of the internal carotid artery are well kown. Results of transoesophageal echocardiography with respect to plaques in the aortic arch and duplex sonography of the internal carotid artery were evaluated and a statistical analysis was performed...

Vascular dementia (VaD) is a history-laden disease entity that dates back to the 19th century when arteriosclerotic brain atrophy due to hardening of the arteries was perceived as the major cause of senile dementia. Its existence had been overshadowed by the emergence of Alzheimer's disease (AD) in the past century and research on AD dominated the field of dementia. Interest in VaD has been revived in recent years as vascular lesions have been shown to make great contributions to the development of dementia, particularly in the elderly...

A 68-year-old woman with hypertension with no history of cerebrovascular events presented with a left-sided hemiplegia which had developed acutely 2 days ago. She was not on maintenance therapy with antiplatelets or anticoagulants. A CT scan showed acute ischaemic infarction of the right internal capsule and cerebellar haemorrhage. Cardiac evaluation was normal. Doppler ultrasonography of the extracranial carotid and vertebral arteries showed diffuse arteriosclerotic changes, but did not reveal any haemodynamic occlusion...

Currently, there is no adequate technique for intraoperative monitoring of cerebral blood flow (CBF). To evaluate laser speckle imaging (LSI) for assessment of relative CBF, LSI was performed in 30 patients who underwent direct surgical revascularization for treatment of arteriosclerotic cerebrovascular disease (ACVD), Moyamoya disease (MMD), or giant aneurysms, and in 8 control patients who underwent intracranial surgery for reasons other than hemodynamic compromise. The applicability and sensitivity of LSI was investigated through baseline perfusion and CO2 reactivity testing...

Peripheral arterial occlusive disease is one manifestation of the systemic disease atherosclerosis. The initial therapy for every arteriosclerotic disease is aimed at reducing cardiovascular risk factors by lifestyle modification and medication. Patients who require surgical revascularisation need long-term antiplatelet therapy or anticoagulation. This therapy has to be differentiated according to the vascular territory involved and the method used for revascularisation. After local thrombendarterectomy, alloplastic bypass graft surgery of the aortic, aorto-iliac, aorto-femoral or femoro-popliteal region above the knee, long-term ASA 100 mg/d or clopidogrel 75 mg/d should be initiated...
