Neurosurgical pathologies presenting during pregnancy are uncommon. If present, the situation creates a unique diagnostic, observational, and therapeutic challenge as both lives are placed at potential risk. Surgical procedures during pregnancy are approached carefully as physiological stressors associated with surgery and anesthesia may cause fetal or maternal compromise. We present the only known case of a pseudoaneurysm treated with an awake craniotomy, allowing us to abate the risks associated with general anesthesia in pregnancy...

Medications and treatments are said to have a palliative effect if they relieve symptoms without having a curative effect on the underlying disease such as atherosclerosis or cancer. Some authors speculated that atherosclerotic coronary artery disease (CAD) could be considered a "cancer of the coronary arterial wall". Although the percutaneous coronary intervention (PCI) has proven to be effective in decreasing mortality rates among patients with acute coronary syndromes, the previous meta-analyses of PCI versus optimal medical therapy for stable CAD have not been able to demonstrate a reduction in major adverse cardiac outcomes...

A 73-year-old man was admitted at another hospital after a traffic accident. The diagnosis was cervical vertebral fracture. Despite conservative treatment, 5 days later he manifested dysarthria due to cerebellar infarction and was transferred to our hospital. Imaging studies revealed right vertebral arterial dissection at the level of the axial fracture. We performed percutaneous transluminal angioplasty with stenting to address his subacute vertebral artery dissection prior to treating the cervical vertebral fracture using external fixation...

We present a case of ophthalmic artery (OA) traumatic avulsion, leading to a post-traumatic subarachnoid hemorrhage (SAH) with ventricular blood invasion and hydrocephalus, mimicking an internal carotid aneurysm rupture. This is the third case of such an event reported in literature and the first without orbital fractures and optic nerve avulsion. Conservative treatment was sufficient for the avulsion, but surgery was needed for the coexisting eye luxation. Traumatic OA avulsion is a rare but possible event and should be suspected in case of basal cisterns SAH, evidence of orbital trauma and CT angiogram or angiographic absence of opacification of the OA...

INTRODUCTION: Mechanical thrombectomy (MT) has been widely accepted as a safe and effective treatment for acute ischemic stroke (AIS). Development of stent retriever devices has been intensively developed over the past two decades. In this study, we compared the effectiveness and safety of a new thrombectomy device with Solitaire FR for the treatment of AIS models. METHODS: Mechanical performance of stent retrievers was tested in vitro. Thrombin-induced thrombus was pre-injected into the right distal external carotid-maxillary artery in 18 dogs to create an acute thrombus occlusion model, and these animals were divided into a Tonbridge group (n=9, with Tonbridge stent Tonbridge Medical Technology) and a Solitaire group as control (n=9, with Solitaire stent, ev3 Neurovascular)...

BACKGROUND: Most intra-coronary stents in use are made of 316 L stainless steel, which contains nickel, chromate and molybdenum. Whether inflammatory and allergic reactions to metals contribute to in-stent restenosis is still a matter of debate. AIM: The aim of this study was to ascertain the relationship between metal allergy and the occurrence of in-stent restenosis. METHODS: Ninety-nine adult patients who underwent two cardiac catheterisations, up to two years apart, were included in the study...

A 63-year-old man presented with an out-of-hospital cardiac arrest. The coronary angiogram with intravascular imaging was performed and showed a mid-left anterior descending artery atherosclerotic cap rupture with thrombus burden treated with drug-eluting stent (DES) implantation. During the hospitalisation in the intensive care unit, the patient experienced recurrent ventricular fibrillations and asystole with transient ST-segment elevation in the inferior leads with normal coronary angiography. A methylergonovine provocative test was therefore performed and showed an occlusive right coronary artery (RCA) spasm...

A previously healthy 61-year-old Caucasian woman presented to the emergency department after collapsing at home with associated abdominal pain radiating to her back. An urgent CT angiogram was requested to rule out a ruptured aortic aneurysm. This showed a large 21 cm fat-containing lesion arising from the mid-pole of the left kidney, with an adjacent 4 cm perirenal haematoma. An initial diagnosis of a ruptured angiomyolipoma was made. Her haemoglobin was 105 g/L, with a creatinine of 104 mmol/L and an eGFR of 47 mL/min...

We report a case of a 47-year-old Caucasian woman with medical history of hypertension and hypokalemia, who presented to Emergency Room with symptoms resembling acute coronary syndrome ST-segment elevation myocardial infarction. Coronary angiogram revealed clear coronary arteries and left ventriculogram confirmed the diagnosis of Takotsubo cardiomyopathy. She was treated conservatively with good clinical outcome. Subsequent testing revealed underlying primary aldosteronism.

Individuals affected by Prader-Willi syndrome (PWS) may show increased risk for coronary artery disease (CAD), which probably relates, at least, with high burden of cardiovascular risk factors.A 27-year-old man with PWS, obesity, hypertension, diabetes mellitus and dyslipidaemia attended the emergency department with complaints of flu-like condition and chest pain. The ECG revealed a mild ST-segment elevation in inferior leads, followed by positive myocardial necrosis biomarkers. Attending to the high cardiovascular risk profile, ST-segment elevation in inferior territory and wall motion abnormalities, a coronary angiogram was performed...

OBJECTIVE: Repair of truncus arteriosus often requires early right ventricular outflow tract (RVOT) re-operation. Using a modified repair the branch pulmonary arteries are left in-situ, which may avoid earlier RVOT reoperation. We hypothesized that our modified repair for Type I and II truncus arteriosus would extend the time to RVOT re-operation. METHODS: Infants with truncus arteriosus were divided into two groups: A) Traditional technique where the branch pulmonary arteries are excised from the truncal root, or B) Modified repair where the branch pulmonary arteries are left in-situ and septated from the truncal root...

Early assessment of the potential for neurologic recovery in comatose cardiac arrest patients (CCAP) has been a challenge despite significant evolution in management and imaging techniques. The purpose of study was to determine if the use of computed tomography perfusion (CTP) in CCAPs is feasible and if this technique can predict the likelihood that CCAPs will have a devastating outcome at hospital discharge. We prospectively enrolled 10 newly admitted comatose adults who had an out-of-hospital cardiac arrest and were treated with standard therapeutic hypothermia protocols...

BACKGROUND: Infective endocarditis (IE) is still a condition with high mortality and morbidity, especially in the elderly, and in patients with prosthetic valves. The concept of "time-to-therapy" plays a key role for the prompt management of IE and related complications, and the currently available multimodality imaging may play a key role in this setting. Myocardial ischemia due to extrinsic coronary compression from an aortic abscess is an extremely rare condition where the optimal therapeutic strategy has not been defined yet...
