Neuro-endoscopic management of hemorrhagic moyamoya disease in the acute stage: single institute experience.

Conclusion: Neuro-endoscopic hematoma removal may be the optimal management method for hemorrhagic MMD in the acute stage in terms of the maximum preservation of pre-existing collateral anastomosis without affecting the potential donor vessels used for future revascularization surgery.

Abstract The authors report on the case of a 65-year-old man suffering progressive gait disturbance and hearing impairment due to superficial siderosis (SS). According to the literature, repeated hemorrhage into the subarachnoid space causes SS; however, the bleeding source remains unknown in half of SS patients. In the presented case, preoperative MRI revealed a fluid-filled intraspinal cavity extending from C2 to T8 with a dural defect at the ventral C7 level. During surgery, the dural defect was seen to connect to the intraspinal cavity filled with xanthochromic fluid. Importantly, endoscopic observation verifi...

Abstract BACKGROUND AND OBJECTIVES: Bedside sonographic duplex technique (SDT) may be used as an adjunct to cranial computed tomography (CCT) to monitor brain-injured patients after decompressive craniectomy (DC). The present study aimed to assess the value of SDT in repeated measurements of ventricle dimensions in patients after DC by comparing both techniques. MATERIALS AND METHODS: Retrospective assessment of 20 consecutive patients after DC for refractory intracranial pressure (ICP) increase following subarachnoid hemorrhage (SAH), bleeding and trauma which were examined by SDT and CCT in the context of r...

AbstractBackgroundRecurrent bleeding from an intracranial aneurysm after subarachnoid hemorrhage (SAH) is associated with unfavorable outcome. Recurrent bleeding before aneurysm occlusion can be performed occurs in up to one in five patients and most often happens within the first 6 h after the primary hemorrhage. Reducing the rate of recurrent bleeding could be a major factor in improving clinical outcome after SAH. Tranexamic acid (TXA) reduces the risk of recurrent bleeding but has thus far not been shown to improve functional outcome, probably because of a higher risk of delayed cerebral ischemia (DCI). To reduce the r...

Abstract BACKGROUND: In patients with SAH and multiple aneurysms, the ruptured lesion must be identified to prevent recurrent bleeding. AIM OF THE STUDY: To assess the diagnostic value of non-enhanced computed tomography (NECT) in identifying the rupture site in patients with subarachnoid haemorrhage (SAH) and multiple aneurysms. MATERIAL AND METHODS: We included patients with SAH revealed by NECT and multiple aneurysms detected on computed tomography angiography (CTA) in whom a ruptured aneurysm was identified during neurosurgery. Two radiologists predicted the location of the ruptured aneurysm based on...

Abstract Aneurysmal subarachnoid hemorrhage (aSAH) is a subtype of hemorrhagic stroke with significant morbidity and mortality. Aneurysmal bleeding causes elevated intracranial pressure, decreased cerebral blood flow, global cerebral ischemia, brain edema, blood component extravasation, and accumulation of breakdown products. These post-SAH injuries can disrupt the integrity and function of blood-brain barrier (BBB), and brain tissues are directly exposed to the neurotoxic blood contents and immune cells, which leads to secondary brain injuries including inflammation and oxidative stress, and other cascades. Thoug...

This study shows that CA are released from periventricular and subpial regions to the cerebrospinal fluid and are present in the cervical lymph nodes, into which cerebrospinal fluid drains through the meningeal lymphatic system. We also show that CA can be phagocytosed by macrophages. We conclude that CA can act as containers that remove waste products from the brain and may be involved in a mechanism that cleans the brain. Moreover, we postulate that CA may contribute in some autoimmune brain diseases, exporting brain substances that interact with the immune system, and hypothesize that CA may contain brain markers that m...

Conclusions: Stroke is uncommon in cirrhotic patients. However, considering a positive relationship of liver cirrhosis with subarachnoid and intracranial hemorrhage, the prophylactic strategy may be selectively adopted in cirrhotic patients.

ConclusionTraumatic dACA aneurysm is a rare complication of brain trauma. Delayed intracranial haemorrhage and the sudden deterioration of neurologic function were the typical characteristics in patients with traumatic dACA aneurysm. CTA is the first-line screening modality for patients who present with intracerebral haemorrhage in the corpus callosum after trauma, particularly for patients who are older, in a poorer or critical condition. When the aneurysm is located in the A4 segment or involves a small branch, surgical trapping is the preferred definitive therapy to prevent further growth and disastrous bleeding. Early ...
