The optimal management and procedural strategy for tandem occlusion (TO) in acute ischemic stroke are still unclear, as is the long-term outcome of these patients. The aim of this study was to evaluate predictors of good functional outcome in patients with TO through the analysis of demographics, clinical, and radiological data with a 1-year follow-up. ⋯ Our research, conducted in a small sample size of patients with acute ischemic stroke due to TO of anterior circulation, found that acute stent placement seems to be safe, improving clinical outcome, and it is associated with low rate of mortality at long-term follow-up.

Surgery is a good treatment option for drug-resistant temporal lobe epilepsy (TLE). 2-deoxy-2-(18F) fluoro-D-glucose (FDG) positron emission tomography (PET) is used to detect epileptic foci as hypometabolic lesions in presurgical evaluation. Visual field defects (VFDs) in the contralateral homonymous upper quadrant are common postoperative complications in TLE. This study aimed to quantify VFDs using pattern deviation probability plots (PDPPs) and examine the effect of hypometabolism in FDG-PET on VFDs. ⋯ PDPP counting is useful for quantifying VFDs. Preoperative dysfunction indicated by preoperative FDG-PET in the posteromedial temporal and medial occipital cortex could enhance VFDs early after TLE surgery.

Two main surgical techniques are available for corpus callosotomy (CC): conventional microscopic CC and endoscopic CC.1 Microscopic CC is more familiar to neurosurgeons and allows three-dimensional visualization, but it requires a larger craniotomy and has a narrower visual angle in the deep part. Endoscopic CC has only recently been introduced to epilepsy surgery, but it is gaining increasing interest among epilepsy surgeons. The endoscope provides two-dimensional visualization and requires a camera as an additional instrument inserted into the surgical corridor. ⋯ In some cases, this procedure can take a long time. On the other hand, a posterior approach requires less interhemispheric arachnoid dissection, or sometimes none at all, due to the anatomy of the falx cerebri. These reasons have driven the development of a posterior approach for an endoscopic-alone technique.3 Here, we present a 5-year-old girl with medically intractable epileptic spasms that were diagnosed as infantile epileptic spasms syndrome, who underwent endoscopic total CC via a posterior approach to control her seizures (Video 1).

Exoscopic retrosigmoid approach for an antero-medial tentorial meningioma: 2-D Operative Video.
We present a 2-dimensional operative video (Video 1) of a suboccipital retrosigmoid approach for an anteromedial tentorial meningioma with a specific focus on the use of a surgical exoscope. The patient is a 50-year-old woman who presented to emergency room with a 6-month history of nausea, dizziness, and gait imbalance secondary to a 2.5-cm homogenously enhancing mass originating from the anteromedial tentorium on the right side with associated brainstem compression. ⋯ Video 1 emphasizes the advantages of the exoscope compared with the microscope in optimizing surgeon efficiency, ergonomics, and comfort.6 The unique operating room setup associated with exoscope use is highlighted. The patient underwent uncomplicated gross total resection with a mild trochlear nerve palsy noted postoperatively that was resolved at follow-up.7.

Isthmic lumbar spondylolisthesis (ILS) is a prevalent spinal pathology. Radicular pain in patients is often attributed to L5-S1 ILS combined with foraminal stenosis (FS), making such patients prime candidates for surgical intervention. We herein aimed to elucidate the surgical technique and clinical outcomes of transforaminal endoscopic lumbar foraminotomy (TELF) in the treatment of L5-S1 ILS with FS. ⋯ TELF emerges as a potentially safe and effective surgical option for alleviating radicular pain in patients with L5-S1 stable ILS combined with FS. While our short-term clinical results are satisfactory, it is necessary to expand the sample size and extend the follow-up time to validate the effectiveness and long-term efficacy of TELF.
