To determine the effectiveness of C2 nerve root decompression and C2 dorsal root ganglionectomy for intractable occipital neuralgia (ON) and C2 ganglionectomy after pain recurrence following initial decompression. ⋯ In the third largest series of surgical intervention for ON, most patients experienced favorable postoperative pain relief. For patients with pain recurrence after C2 decompression, salvage C2 ganglionectomy is a viable surgical option and should be offered with the potential for complete pain relief and improved quality of life (QOL).

Paraspinal textiloma (ParaTex) is a well-known complication after posterior lumbar surgery. However, there are few articles on this topic, probably because of medicolegal concerns. In addition, patients with ParaTex can remain asymptomatic for months or even years unless it causes complications. The purpose of this study is to review our experience on this "undesirable" topic to increase awareness among spinal surgeons and radiologists and avoid unnecessary morbidity, which is still being encountered. ⋯ ParaTexs are more common in obese patients, after emergency surgery, and with unplanned changes in surgical procedure. On computed tomography scan, the classic spongiform appearance is highly suggestive. Magnetic resonance imaging findings are variable and less specific, but confrontation of imaging data with the surgical history helps with the preoperative diagnosis. In the early postoperative period symptoms are related to the exudative response; at later times symptoms may be linked to pseudotumor formation clinically and radiologically. Appropriate antibiotic therapy is recommended when a septic complication is present or suspected. Strict measures must be taken to prevent this complication. Surgical sponges should always be counted at least three times (preoperatively, at closure, and at the end), radiopaque markers should be used, and if there is doubt, intraoperative radiography must be performed.

The association between intracranial aneurysms and arteriovenous malformations (AVMs) or dural arteriovenous fistulas (DAVFs) has been well documented, and the changes in cerebral blood flow dynamics were thought to be one of the major causes. There has not been a report on intracranial aneurysms associated with multiple DAVFs and AVMs in the same patient. ⋯ To our knowledge, this is the first report of a very rare case with a unique combination of cerebrovascular pathologies including multiple aneurysms, DAVFs, and 1 high-grade AVM. Analyzing the hemodynamic relationships of these concurrent lesions is essential to determine the hemorrhage risk of each lesion and the order of priority in management. Flow-related aneurysms with irregular morphology require early, aggressive treatment.

Prompt access to arterial occlusion is the key to successful endovascular revascularization in acute stroke. We present the first reported case utilizing anterior-to-posterior circulation approach for a successful mechanical thrombectomy and chemical thrombolysis of an acute basilar artery (BA) occlusion using the Penumbra Aspiration System. ⋯ In patients with unfavorable VA anatomy, anterior-to-posterior thrombectomy of the BA can be successfully achieved using the Penumbra catheter via an anatomically suitable posterior communicating artery.

The anterolateral approach is one of the main routes for accessing suprachiasmatic lesions involving the anterior communicating artery (AComA) complex. Pterional (PT) craniotomy and its alternatives, including orbitozygomatic, orbitopterional, and mini-supraorbital craniotomies, have been developed as tailored frontotemporal craniotomies. One of the main differences between PT craniotomy and its alternatives is the removal of the orbital bone along with the sphenoid wing. However, which bone part is the most important to remove has not been discussed in relation to frontal lobe retraction. We have evaluated how the removal of the supraorbital bar versus the removal of the lateral orbital wall along with the sphenoid wing affects the relationship between the levels of frontal lobe retraction and area of exposure (AOE) in the suprachiasmatic region. ⋯ Treatment of lesions in the suprachiasmatic region via an anterolateral route involving a frontotemporal craniotomy requires sufficient removal of the lateral orbital wall along with the greater sphenoid wing so that brain retraction is minimized.
