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.

Multiple reports have attributed a prognostic value to routine blood tests results for patients with glioblastoma. However, these studies have reported conflicting results and have often had small sample sizes. We sought to validate the prognostic value of the described tests in an independent glioblastoma patient population. ⋯ In the present study, hemoglobin, white blood cell, monocyte, neutrophil, leukocyte, and platelet counts, neutrophil/lymphocyte ratio, C-reactive protein, erythrocyte sedimentation rate, activated partial thromboplastin time, prothrombin time, and lactate dehydrogenase levels did not independently predict for overall survival in patients with glioblastoma.

Klippel-Trenaunay-Weber syndrome (KTWS) is a rare syndrome characterized by the triad of cutaneous hemangiomas, venous varicosities, and osseous-soft tissue hypertrophy of the affected limb. Clinical manifestations, genetic testing, and radiologic imaging are the key steps in diagnosing this syndrome. ⋯ KTWS is a rare disease with a wide range of manifestations. Multisystemic evaluation of this group of patients should be performed to identify cavernous hemangiomas at the early stage of life and adequately treat them in the future. Treatment of KTWS patients with cavernous hemangiomas should not be different from the treatment of patients with any other hemangiomas, and surgical intervention should be considered on a case-to-case bases.

Intravenous 3D digital subtraction angiography during surgical treatment of an intracranial aneurysm.
Although intraarterial 3-dimensional digital subtraction angiography (ia-3DDSA) using an angiographic C-arm system is still the gold standard for postoperative confirmation of surgical clipping of intracranial aneurysms, ia-3DDSA requires catheterization and intraarterial injection of contrast medium, which adds risks to the surgical procedure and takes time. We propose a less invasive acquisition of 3D digital subtraction angiography with intravenous injection (iv-3DDSA) in the hybrid operating room to confirm the results of surgical clipping immediately after surgery. ⋯ Iv-3DDSA can be useful for postsurgical confirmation of clipping of aneurysms in the hybrid operating room.

The present study investigated the clinical and morphological characteristics of the vertebrobasilar artery associated with vascular healing in patients with unruptured spontaneous intracranial vertebral artery (VA) dissection (VAD). ⋯ Spontaneous vascular normalization of unruptured spontaneous intracranial VAD might be associated with female sex, nonsmoking, no posteroinferior cerebellar artery involvement, a smaller vertebral-union-basilar angle and vertebral-union-vertebral angle, distal dissection from the VA union, less basilar artery bending, and luminal irregularity/steno-occlusion.
