BACKGROUND: In the absence of a standardized safe surgical reentry strategy for high-risk patients with large or anterior postoperative aortic false aneurysm (PAFA), we aimed to describe an effective and safe approach for such patients. METHODS: We prospectively analyzed patients treated for PAFA between 2006 and 2015. According to the preoperative computed tomography scan examination, patients were divided into two groups according to the anatomy and extension of PAFA: in group A, high-risk PAFA (diameter ≥3 cm) developed in the anterior mediastinum; in group B, low-risk PAFA (diameter <3 cm) was situated posteriorly...

Posterior cerebral artery (PCA) aneurysms are rare, and direct surgery of these is considered difficult. Coil embolization of PCA aneurysms is becoming popular. However, it is difficult to completely obliterate the aneurysm while preserving the flow of the parent artery in large or giant PCA aneurysms with a wide neck with this technique. We report a case of a large and wide-necked PCA aneurysm with multiple recurrences following successful surgical clipping and coil embolization.A 77-year-old man with a large unruptured right PCA (P2) aneurysm was successfully treated by surgical clipping...

Laser speckle flowgraphy (LSFG) is an ophthalmologic equipment that qualitatively detects the blood flow of the optic nerve head, which is known to be related with cerebral microcirculation. LSFG can also measure the mean blur rate, which quantitatively calculates the blood flow. We aimed to assess the utility of LSFG in the evaluation of cerebral perfusion during aortic surgery under hypothermic circulatory arrest with retrograde and antegrade cerebral perfusion. Two patients underwent total arch replacement for aneurysm...

BACKGROUND: Due to the continuing improvements in imaging technology, an increasing number of epileptogenic small (≤5mm) unruptured intracranial aneurysms (sUIA) are being diagnosed since 2000. However, they are not systematically described and reviewed until now. CASE DESCRIPTION AND THE LITERATURE REVIEW: We reported 2 patients with sUIA who initially presented with complex partial seizures (CPS). Scalp electroencephalography (EEG) showed the seizures activity arising from the mesial temporal/frontal areas, but conventional magnetic resonance imaging (MRI) scans were normal in both patients...

OBJECTIVE: Endovascular treatment is one of the most important treatments along with open craniotomy for cerebrovascular surgery. The successful treatment of endovascular disease relies on appropriate instruments and the surgeon's skill. Endovascular treatment needs to provide safe and stable access to the catheter cavity. Additionally, it is important to maintain a round shape without changing to an oval shape. The catheter for endovascular treatment has to be flexible and accommodate at least 0...

INTRODUCTION: Diffuse alveolar hemorrhage (DAH) is a very rare complication but acute and life-threatening event. Clopidogrel has generally administered for neurointerventional surgery, but there were no reports of DAH related to clopidogrel in patients undergoing neurointervention. CASE PRESENTATION: A 70-year-old male presented with DAH associated with clopidogrel after transfemoral cerebral angiography and coil embolization for cerebral aneurysm. The chest radiography showed bilateral symmetric peribronchial consolidation and bronchoscopy revealed diffuse hemorrhage on the bronchial wall at the bilateral lung...

Intraoperative indocyanine green(ICG)videoangiography is simple, less invasive, and enables real-time observation of hemodynamics during neurovascular surgery. In this article, we describe a case of ruptured distal middle cerebral artery aneurysm, which was unclippable and required parent artery occlusion with extracranial-intracranial bypass. Under temporary clipping of the proximal vessel, ICG videoangiography demonstrated the proper target vessel for bypass through delayed and retrograde filling of the dye...

OBJECT Management of complex aneurysms of the middle cerebral artery (MCA) can be challenging. Lesions not amenable to endovascular techniques or direct clipping might require a bypass procedure with aneurysm obliteration. Various bypass techniques are available, but an algorithmic approach to classifying these lesions and determining the optimal bypass strategy has not been developed. The objective of this study was to propose a comprehensive and flexible algorithm based on MCA aneurysm location for selecting the best of multiple bypass options...

Extracranial internal carotid artery (ICA) aneurysms located at the entrance of the skull are a rare pathology. Surgical treatment is indicated for this pathology because of the risk of arterio-arterial embolism and the development of cerebrovascular disease. The domestic and international literature reports single cases or small group cases of successful surgical treatment of patients with distal internal carotid artery aneurysms associated with pathological kinking of the artery. Open surgery for aneurysms of this localization is complicated because of a high injury risk associated with the approach...

BACKGROUND: Antegrade cerebral perfusion in aortic surgery is a well-established brain protection method. Open distal anastomosis during aortic surgery has some well-known advantages. Antegrade cerebral perfusion allows repair to some extent of the aortic arch, even in isolated ascending aortic aneurysm. The present study aims to investigate the adequacy of contralateral perfusion with novel oxidative stress parameters during unilateral antegrade cerebral perfusion. METHOD: The study included 30 consecutive patients undergoing thoracic aortic surgery with unilateral antegrade cerebral perfusion (uACP) under moderate hypothermia (28° C)...

A giant serpentine aneurysm (GSA) in the anterior cerebral artery (ACA) poses a technical challenge in treatment given its large size, unique neck, and dependent distal vessels. Here we report the case of a GSA in the ACA successfully treated with a combined surgical and endovascular approach. A 54-year-old woman presented with dull headache. On brain computed tomography (CT), a large mass (7 cm × 5 cm × 5 cm) was identified in the left frontal lobe. Cerebral angiography revealed a GSA in the left ACA. Bypass surgery of the distal ACA was performed, followed byocclusion of the entry channel via an endovascular approach...
