INTRODUCTION: Subclavian artery pseudoaneurysms are rare and occur mostly as a consequence of an inadvertent arterial puncture during central venous catheterization, endovascular therapeutic procedures or after penetrating or blunt trauma. They usually have a late clinical presentation, with pain, swelling or other compressive symptoms. The optimal treatment in this situation is still a matter of debate. The authors describe a case of late presentation of subclavian artery pseudoaneurysm after transjugular hepatic biopsy and discuss the several options for treatment...

Despite advancements in treating ruptured cerebral aneurysms, an aneurysmal subarachnoid hemorrhage (aSAH) is still a grave cerebrovascular disease associated with a high rate of morbidity and mortality. Based on the literature published to date, worldwide academic and governmental committees have developed clinical practice guidelines (CPGs) to propose standards for disease management in order to achieve the best treatment outcomes for aSAHs. In 2013, the Korean Society of Cerebrovascular Surgeons issued a Korean version of the CPGs for aSAHs...

In interventional neuroradiology, endovascular embolization represents an important and helpful tool in the treatment of multiple head and neck diseases. These interventional procedures may be performed with curative intent, to reduce the surgical risk within a multimodal treatment concept, or to improve or at least maintain a good quality of life within a palliative therapy concept. In addition to a good understanding of disease pathology, knowledge of vascular anatomy, including collateral vessels and dangerous extracranial-intracranial anastomoses, is essential for successful treatment, as is implementation of an established technique using appropriate material...

INTRODUCTION: Spontaneous dissections of intracranial arteries are rare, but important causes of stroke, especially in younger patients. Dissections of the anterior cerebral artery (ACA) have been reported only very rarely in the European and North American populations but might be more prevalent than previously thought. METHODS: This paper describes the presenting pattern of the disease, the clinical and imaging findings, as well as endovascular therapeutical options with respect to a meta-analysis of cases reported in the literature...

BACKGROUND: Management of small aneurysms often poses a therapeutic dilemma and surgical treatment or coiling can be considered as therapeutic choices. In the present study, we reviewed our series of ruptured small cerebral aneurysm treated surgically. METHODS: A total of 53 consecutive patients with ruptured small aneurysm were surgically treated between January 2008 and July 2014. Data were retrospectively collected. Procedure-related death and complications were systematically reviewed...

Aneurysmal subarachnoid hemorrhage (aSAH) is a kind of hemorrhagic stroke with high mortality and morbidity. Although the preoperative diagnosis, surgical clipping, endovascular treatment, and intensive care have progressed in recent years, the overall prognosis of aSAH patients remains poor. In 2011, the Neurocritical Care Society organized an international, multidisciplinary consensus conference addressed the critical care management of SAH. In 2012, the American Stroke Association (AHA) updated the guidelines of diagnosis and treatment of aSAH published in 2009...

OBJECTIVE: The cerebellopontine angle is a common site for tumor growth and vascular pathologies requiring surgical manipulations that jeopardize cranial nerve integrity and cerebellar and brainstem perfusion. To date, a detailed study of vessels perforating the cisternal surface of the middle cerebellar peduncle-namely, the paraflocculus or parafloccular perforating space-has yet to be published. In this report, the perforating vessels of the anterior inferior cerebellar artery (AICA) in the parafloccular space, or on the cisternal surface of the middle cerebellar peduncle, are described to elucidate their relevance pertaining to microsurgery and the different pathologies that occur at the cerebellopontine angle...

OBJECTIVES: It has been 10 years since the publication of International Subarachnoid Aneurysm Trial (ISAT) (1-3) and the first-line treatment for cerebral aneurysms in many UK neurosurgical centres is endovascular occlusion. Local audit has shown a significant reduction in surgical clipping cases since 2002, with a fall from over 150 cases per year pre ISAT, to approximately 25 cases per year currently. More so the cases referred for surgical occlusion represent more challenging lesions...

BACKGROUND AND OBJECTIVE: Intraoperative monitoring (IOM) has been used in different surgical disciplines since the 1980s. Nonetheless, regular routine use of IOM in interventional neuroradiology units has only been reported in a few centers. The aim of this study is to report our experience, 1 year after deciding to implement standardized IOM during endovascular treatment of vascular abnormalities of the central nervous system. METHODS: Basic recordings included somatosensory-evoked potentials (SEPs) and motor-evoked potentials (MEPs)...

Major reasons to treat brain arteriovenous malformations (AVMs) are to reduce the risk of brain hemorrhage, control intractable seizure, and in some cases alleviate neurologic deficits. Once an AVM has hemorrhaged, the risk of further hemorrhage is increased and it should be treated. The treatment plan ideally is based on interdisciplinary discussion between neurosurgery, endovascular neuroradiology, and radiotherapy, moderated by neurology in an experienced center. Complete removal or obliteration of the malformation should be the goal, as partial treatment only exposes the patient to treatment risks with a residual hemorrhage risk...

The treatment of complex intracranial aneurysms remains a therapeutic challenge. These lesions are frequently not amenable to selective clipping or coiling or other endovascular procedures and surgery still has a predominant role.We illustrate our "surgical decision making" for managing complex intracranial aneurysmal lesions. The best strategy is decided on the basis of pre-operative neuroradiological and intra-operative main determinants such as anatomical location, peri-aneurysmal angioanatomy (branch vessels, critical perforators), broad neck, intraluminal thrombosis, aneurysmal wall atherosclerotic plaques and calcifications, absence of collateral circulation, and previous treatment...

BACKGROUND: The treatment of cerebral aneurysms has undergone significant evolution since the 1990s when the endovascular methods were introduced. After the results of ISAT were published in 2002, a change in practice occurred which resulted in more ruptured aneurysms treated endovascularly rather than by surgical clipping. This change in practice was referred to as a paradigm shift. OBJECTIVES: The aim of this study was to review the treatment outcomes in patients with ruptured anterior cerebral aneurysms and to delineate the trends in surgical management in the age of the formation of centers for interventional neuroradiology...
