OBJECTIVE: The aim of the study was to find a neuromarker of perioperative anxiety in a patient with critical carotid stenosis through the use of neuromarkers in Quantitative EEG (QEEG) and Event Related Potentials (ERPs). The indirect purpose of the research was evaluation of improvement in the patient's quality of life. CASE STUDY: A 45-year-old woman was admitted to the Department of Vascular Surgery and Endovascular Interventions at the John Paul II Hospital in Krakow, with the diagnosis of critical internal carotid stenosis (over 80%), confirmed by Doppler Ultrasound and Angio-CT examinations...

The article represents a case of a young patient with atypical clinical and paraclinical presentation of vertebral artery dissection by multiple cerebral infarcts, localized at the supratentorial and infratentorial levels in the posterior circulation. A case of a 21-year-old man, without a history of trauma in the cervical area or at the cranial level, without recent chiropractic maneuvers or practicing a sport, which required rapid, extreme, rotational movements of the neck, was examined. He presented to the emergency room with nausea, numbness of the left limbs, dysarthria, and incoordination of walking, with multiple objective signs at the neurological examination, which revealed right vertebral artery subacute dissection after the paraclinical investigations...

PURPOSE: Traumatic aortic injury (TAI) is a rare but life-threatening type of injury. We investigate whether the anatomy of the aortic arch influences the severity of aortic injury. METHODS: This is a retrospective study of twenty-two cases treated with TEVAR for TAI in our department from 2009 to 2014. Aortic injury was assessed in accordance with the recommendations of the Society of Vascular Surgery. We measured the aortic arch angle and the aortic arch index, based on the initial angio-CT scan, in each of the analyzed cases...

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...

INTRODUCTION: We present our experience on idiopathic intracranial hypertension (IIH), before and after the introduction of a specific diagnosis and management protocol. METHOD: A descriptive retrospective study was conducted on patients with IIH over a 25year period (1990-2015), comparing the last 7years (after introduction of the protocol) with the previous 18years. RESULTS: Among the 18,865 patients evaluated, there were 54 cases of IIH (29 infants and 25 children)...

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: The important role of radiological examinations of invasive pulmonary aspergillosis (IPA) in patients with neutropenia has been well studied; however, little is known about IPA in critically ill chronic obstructive pulmonary disease (COPD) patients. OBJECTIVES: To evaluate the value of radiological examinations in the diagnosis and prognosis of invasive bronchial-pulmonary aspergillosis (IBPA) in critically ill COPD patients. METHODS: We included 61 critically ill COPD patients in the intensive care unit (ICU) in a retrospective, single-center cohort study...

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...

The present study describes the technical feasibility of a combined-modality angiography/computed tomography (angio-CT)-assisted balloon dissection technique for bowel protection during renal cryoablation in six procedures in five patients. A retrospective review was performed to evaluate balloon dissection using the angio-CT system. Mean bowel-to-tumor distances before and after balloon dissection were 0.9 mm (range, 0-3 mm) and 13.0 mm (range, 11-17 mm), respectively. No bowel injury was observed during the mean follow-up period of 19 months (range, 7-44 mo)...

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...

OBJECTIVES: We investigated the frequencies and factors associated with the presence of extra-hepatic feeding arteries (EHFAs) of hepatocellular carcinoma (HCC) using intra-arterial CT aortography images. METHODS: A total of 173 patients with HCC who underwent transarterial chemoembolization (TACE) in our institution between January 2013 and March 2015 were enrolled. The types of EHFAs were evaluated by CT aortography images using an apparatus that combines multidetector-row computed tomography and angiography system...
