Direct carotid puncture for mechanical thrombectomy in acute ischemic stroke patients with prohibitive vascular access.
While the benefit of mechanical thrombectomy (MT) for patients with anterior circulation acute ischemic stroke with large-vessel occlusion (AIS-LVO) has been clearly established, difficult vascular access may make the intervention impossible or unduly prolonged. In this study, the authors evaluated safety as well as radiographic and functional outcomes in stroke patients treated with MT via direct carotid puncture (DCP) for prohibitive vascular access. ⋯ DCP for emergency MT in patients with anterior circulation AIS-LVO and prohibitive vascular access is safe and effective and is associated with higher recanalization rates, smaller infarct volumes, and improved functional outcome compared with patients with abMT after failed transfemoral access. DCP should be considered in this patient population.

Corticotroph hyperplasia and Cushing disease: diagnostic features and surgical management.
This study was done to compare corticotroph hyperplasia and histopathologically proven adenomas in patients with Cushing disease by analyzing diagnostic features, surgical management, and clinical outcomes. ⋯ This study suggests an association between biochemically proven Cushing disease and histopathologically proven corticotroph hyperplasia. Imaging and operative findings can be ambiguous, and, compared to typical adenomas with a pseudocapsule, the surgical approach is more nuanced. Nevertheless, if treated appropriately, biochemical outcomes may be similar.

Endoscopic bimanual sharp dissection technique for gross-total resection of colloid cysts: technical note.
Neuroendoscopic resection of colloid cysts has gained tremendous popularity over the last 2 decades because of good clinical outcomes and a low complication profile. However, in comparison to microsurgical resections, endoscopic resection has a lower rate of gross-total resection, which leaves the patient at risk for cyst recurrence. At present, there is still ongoing debate as to the best surgical approach for colloid cysts. ⋯ It is the authors' belief that gross-total resection should be the aim of endoscopic cyst resection. In this technical note, they describe their surgical technique for achieving safe gross-total resection of colloid cysts by using a ventriculoscopic system. The surgical technique includes a far anterolateral entry point, navigational guidance, bimanual sharp dissection, use of the endoscopic sheath as a retractor, the small-chamber irrigation technique, and the dry-field technique for hemostasis.

Earlier radiosurgery leads to better pain relief and less medication usage for trigeminal neuralgia patients: an international multicenter study.
Trigeminal neuralgia (TN) is a chronic pain condition that is difficult to control with conservative management. Furthermore, disabling medication-related side effects are common. This study examined how stereotactic radiosurgery (SRS) affects pain outcomes and medication dependence based on the latency period between diagnosis and radiosurgery. ⋯ TN patients managed with SRS within 4 years of diagnosis experienced a shorter interval to pain relief with low risk. SRS also yielded significant decreases in adjunct medication utilization. Radiosurgery should be considered earlier in the course of treatment for TN.

Gamma Knife central lateral thalamotomy for the treatment of neuropathic pain.
The goal of this study was to assess the safety and efficacy of stereotactic central lateral thalamotomy with Gamma Knife radiosurgery in patients with neuropathic pain. ⋯ Safe, nonpharmacological therapies are imperative for the management of refectory chronic pain conditions. The present series demonstrates that Gamma Knife central lateral thalamotomy is safe and potentially effective in the long term for relieving chronic neuropathic pain refractory to pharmacotherapy and for restoring quality of life.
