BACKGROUND: Using flat-detector CT (FD-CT) for stroke imaging has the advantage that both diagnostic imaging and endovascular therapy can be performed directly within the Angio Suite without any patient transfer and time delay. Thus, stroke management could be speeded up significantly, and patient outcome might be improved. But as precondition for using FD-CT as primary imaging modality, a reliable exclusion of intracranial hemorrhage (ICH) has to be possible. This study aimed to investigate whether optimized native FD-CT, using a newly implemented reconstruction algorithm, may reliably detect ICH in stroke patients...

This case report is about a 70-years-old female patient, suffering from discal hernia, with compression of the iliac vein, that led to the formation of deep vein thrombosis of the lower limbs. The angio-CT scan revealed the starting point of the L4- L5 compression where a voluminous discal hernia caused deep vein thrombosis, with the involvement the femoro-popliteal venous axis. Blood samples and PET-CT scans excluded other possible etiologic factors. This case demonstrates how a voluminous discal hernia can cause venous thrombosis...

Activation of the inflammatory generating complement system might play a pathogenic role in spontaneous subarachnoid hemorrhage (SAH). We studied whether plasma and cerebrospinal fluid (CSF) levels of complement proteins were associated with angiographic vasospasm and cerebral ischemic lesions after SAH. Ficolin-1 (M-ficolin), ficolin-3 (H-ficolin), mannose-binding lectin (MBL), MBL-associated serine protease 2 (MASP-2), MASP-3, and MAp44 were analyzed in plasma of 45 SAH patients at 24 h after bleeding. Additionally, ficolin-1 levels were measured in cerebrospinal fluid (CSF) samples obtained 24 h after bleeding in 19 patients with external ventricular drainage placement...

INTRODUCTION: Bronchogenic cysts, commonly located in the mediastinum or lung parenchyma, arise from abnormal budding of the tracheobronchial tree. Since an unknown percentage of asymptomatic adult patients with bronchogenic cysts remain undiagnosed, the true natural history ofthese cysts in adults is uncertain and the available series reflect a significant selection bias in favor of the symptomatic individual. CASE REPORT: We present the case of a 42-year-old female who presented with adull central chest pain, which gradually worsened overseveral weeks...

Acute type A aortic dissection (AAAD) remains one of the most challenging diseases in cardiothoracic surgery and despite numerous innovations in medical and surgical management, early mortality remains high. The standard treatment of AAAD requires emergency surgery of the proximal aorta, preventing rupture and consequent cardiac tamponade. Resection of the primary intimal tear and repair of the aortic root and aortic valve are well-established surgical principles. However, the dissection in the aortic arch and descending untreated aorta remains...

A 75-year-old man with hypertension and atrial fibrillation was admitted to our emergency room with right-sided hemiplegia and complete aphasia (National Institutes of Health Stroke Scale [NIHSS] score = 18). A noncontrast computed tomography scan showed a slight hypodensity in the left insular region and a bright hyperdense sign in the M1 tract of the left middle cerebral artery (MCA). Angio-CT confirmed an occlusion of the M1 tract of the MCA. Magnetic resonance diffusion-weighted imaging/perfusion-weighted imaging was obtained and revealed a mismatch in the left parietal cortical region...

BACKGROUND AND PURPOSE: There are no generally accepted criteria for the etiologic classification of intracerebral hemorrhage (ICH). For this reason, we have developed a set of etiologic criteria and have applied them to a large number of patients to determine their utility. METHODS: The H-ATOMIC classification includes 7 etiologic categories: Hypertension, cerebral Amyloid angiopathy, Tumour, Oral anticoagulants, vascular Malformation, Infrequent causes and Cryptogenic...

We report a case of epithelioid angiosarcoma of the abdominal aortic wall after endovascular treatment for abdominal aortic aneurysm (EVAR). A 60-year-old male, treated 7 years before with EVAR, presented with abdominal back pain, general fatigue, and fever. It was assumed to be a graft infection with periaortic tissue compatible with an inflammatory reaction. The endograft was therefore completely removed and a Dacron silver aorto-bisiliac graft was implanted. After a few days the patient worsened, the angio-computed tomography scan showed a progressive increase of the periaortic mass and numerous small nodules in the abdomen were also detected...

BACKGROUND: Unruptured intracranial aneurysms (UIAs) are reported more frequently nowadays but their management is not well established; it depends on different structural features of the aneurysms and on multiple patient's risk factors. With this prospective observational study we report our preliminary experience by using four-dimensional (4D) computed tomographic (CT) angiography with ECG-gated reconstructions in the evaluation of dynamic modifications of the aneurysm wall, as a potential predicting factor of growth or rupture...

BACKGROUND: Endovascular treatment of proximal supra-aortic trunks (SAT) has become a safe and reliable alternative to conventional open surgery, with a lower morbimortality rate and good short- and middle-term patency rates. The aim of our study was to assess the long-term results of endovascular treatment of proximal lesions of the SAT (brachiocephalic trunk, common carotid artery, and subclavian artery) and identify predictive risk factors of restenosis. METHODS: From 1999 to 2013, 67 consecutive stenotic lesions of the proximal SAT were treated by angioplasty (13...

Dysphagia is an impairment of swallowing that may involve any structures from the mouth to the stomach. Esophageal dysphagia presents with the sensation of food sticking, pain with swallowing, substernal pressure, or chronic heartburn. There are many causes of esophageal dysphagia, such as motility disorders and mechanical and inflammatory diseases. Infrequently dysphagia arises from extrinsic compression of the esophagus from any vascular anomaly of the aortic arch. The most common embryologic abnormality of the aortic arch is aberrant right subclavian artery, clinically known as arteria lusoria...

For over 20 years, we have been using the transbrachial approach as the first-line option for abdominal angiography and transcatheter arterial chemoembolization (TACE). The present study involving 6262 patients (success rate of 99.8%) showed that the transbrachial approach could be used for superselective angiography or computed tomography during angiography (angio-CT) and was effective for hemostasis of abdominal aneurysmal hemorrhage, diverticular hemorrhage and partial splenic embolization. The approach was highly safe with no association with serious complications...
