We present the case of a 57-year-old female with hypertension, current smoker status, and recent headaches. Imaging studies showed an unruptured 8-mm basilar apex wide neck aneurysm located 4 mm above posterior clinoid (Figure 1) with a 3-mm anterior communicant artery aneurysm. No contraindications were encountered for endovascular treatment, although after we evaluated endovascular and surgical options, surgical clipping was considered also a safe and favorable option based on anterior projection of aneurysm, height of the basilar artery bifurcation, small and elongated posterior communicant artery, and available space between posterior clinoid and basilar artery (4 mm). ⋯ Micro-Doppler and intraoperative angiogram confirmed aneurysm exclusion and patent parent vessels (Video 1). The patient developed minimal ptosis due to partial right oculomotor nerve palsy that recovered completely in 2 weeks; otherwise, her neurologic exam was normal. At 1-year follow up, computed tomography angiography showed complete aneurysm exclusion.

Case Reports
Endoscopic transnasal cryo-assisted removal of orbital cavernous hemangiomas: case report and technical hints.
Cryoprobe devices are used by ophthalmic and orbital surgeons for extraction of fluid-filled intraorbital lesions. No series has described cryodissection via an exclusively transnasal approach. We describe 2 cases of purely endoscopic transnasal removal of intraconal orbital hemangiomas with the aid of a dedicated cryoprobe. ⋯ Cryoprobes represent an adjunctive tool in the orbital surgeon's armamentarium useful in the extraction of fluid-filled intraorbital lesions. This preliminary experience suggests that their use can ease the removal of intraconal hemangiomas with an exclusively transnasal approach. The analysis of further cases is necessary to confirm safety and efficacy.

Vertebrobasilar insufficiency (VBI) is associated with high rates of morbidity and mortality, especially after failure of first-line medical and/or endovascular therapies. Although the optimal therapeutic strategy for refractory VBI remains unclear, surgical bypass represents a potentially life-saving treatment in this patient subset. ⋯ Refractory VBI has high morbidity, with cerebral bypass representing a safe and potentially efficacious treatment for selected patients. Long-term post-bypass outcomes are dependent on the level of irreversible preoperative neurologic injuries.

Case Reports
Giant cerebral aneurysm in a patient with Cowden syndrome treated with surgical clipping; a case report.
Cowden syndrome is characterized by multiple hamartomas and accompanied by a germline mutation of the phosphatase and tensin homolog gene. Cowden syndrome has been described to be associated with vascular anomalies such as arteriovenous malformation and developmental venous anomalies with high frequency. However, the association of cerebral aneurysms with this syndrome has not been reported yet. ⋯ We present this rare case that potentially indicates an association between cerebral aneurysms and Cowden syndrome. Because vascular anomalies are not included in the diagnostic criteria for Cowden syndrome, intracranial vascular anomalies may be underestimated. We therefore recommended a careful search of vascular diseases, including cerebral aneurysms, in cases of Cowden syndrome.

The restoration of shoulder function after brachial plexus injury is a high priority. Shoulder abduction and stabilization can be achieved by nerve transfer procedures including spinal accessory nerve (SAN) to suprascapular nerve (SSN) and radial to axillary nerve transfer. The objective of this study is to compare functional outcomes after SAN to SSN transfer versus the combined radial to axillary and SA to SSN transfer. ⋯ Patients with brachial plexus injury and an intact C7 root could benefit from radial to axillary transfer in addition to SAN to SSN transfer. There was no association between recovery of shoulder abduction and time interval from injury to surgery, age, sex, smoking, and BMI.
