Ruptured blister aneurysms of the internal carotid artery are challenging to treat because of their difficult diagnosis and the fragility of the wall structure. Here, we sought to clarify the efficacy of extracranial-intracranial bypass followed by trapping (bypass/trapping) for ruptured blister aneurysms. ⋯ Bypass/trapping is effective to prevent rebleeding. Early surgery may be beneficial, because most patients in the elective surgery group showed rebleeding or aneurysmal growth. Vessel wall magnetic resonance imaging is a useful adjunct for early diagnosis and may contribute to prompt early surgery.

Endovascular Approach to Cerebral Revascularization: Historical Vignette.
From their origins as cardiovascular research tools, endovascular techniques have evolved to provide a minimally invasive means of diagnosis and therapy for individuals suffering from occlusive artery disease. The techniques were pioneered by William Harvey, whose work set the stage for all subsequent endovascular experiments. These included the bold self-catheterization procedure performed by Werner Forssmann in 1929, which would lead to his dismissal by his superiors, only to regain respect within the medical community in 1956 on receiving the Nobel Prize. ⋯ Having been meticulously evaluated and compared with open vascular procedures, endovascular neurosurgery has continued to be refined and optimized. Understanding the history and development of these techniques and their applications in neurosurgery is necessary to appreciate the current clinical utility of these procedures, serving to provide the vascular neurosurgeon a greater array of treatment options for patients. Here we explore the major scientific and technological advancements that facilitated the development of the endovascular approach to cerebral revascularization, as well as current indications and ongoing clinical trials.

Semmelweis reflex is a human behavioral tendency to stick to preexisting beliefs and to reject fresh ideas that contradict them (despite adequate evidence). We aim to familiarize the readers with the term that not only has a significant historical background but also grave clinical implications. ⋯ The age-old prejudice that is Semmelweis reflex is explored in this review. With careful and thorough study design, scientific rigor, and critical self-analysis of the manuscript, one can avoid being victimized by this reflex. The dual edged nature of this reflex lays unveiled when its importance is highlighted in the prematurely accepted medical failures. Understanding that any new idea goes through the grill of being critically analyzed and perceived encourages the scientist to hold on to the original thought as it may rather be practice changing.

To review the microsurgical anatomy of the donor arteries for extracranial-intracranial bypass, namely, the superficial temporal artery (STA), occipital artery (OA), and internal maxillary artery (IMA). ⋯ A precise understanding of the anatomic characteristics of the donor arteries and their relationships with surrounding structures provides safe access to these arteries.

Spinal cord injury remains a highly morbid entity, with limited treatment modalities in both acute and chronic settings. Clinical research efforts to improve therapeutic guidelines are confounded by initial evaluation inaccuracies, as presentations are frequently complicated by trauma and objective diagnostic and prognostic methods are poorly defined. The purpose of our study was to review recent practical advances for further delineation of these injuries and how such classification may benefit the development of novel treatments. ⋯ Recent advances in accurate, timely, and practical classification methods of acute spinal cord injury will assist in the development of novel treatment approaches for both acute and chronic injury alike.
