Case Reports
Transorbital Penetrating Intracranial Injury with an Umbrella Wire causing Cavernous ICA Injury and Thrombosis.
Transorbital penetrating intracranial injuries, though rare, can have serious consequences. Intracranial penetration can be present even if orbital trauma is trivial. ⋯ Trivial orbital injuries can be associated with significant intracranial injury in a neurologically intact patient. This case emphasizes the potentially injury-prone opening mechanism of conventional umbrellas. A high index of suspicion is important while evaluating such patients.

To compare the anatomical exposure and petrosectomy extent in the Kawase and posterior intradural petrous apicectomy (PIPA) approaches. ⋯ The Kawase approach allows wide exposure of the middle cranial fossa (MCF) and posterior cranial fossa, requiring extradural temporal lobe retraction and an extradural petrosectomy with preservation of the internal acoustic meatus and cochlea. No temporal lobe retraction and direct control of neurovascular structures make the PIPA approach a valid alternative for lesions extending mostly in the Posterior cranial fossa with minor extension in the MCF. The longer surgical corridor, cerebellar retraction, and limited exposure of the anterior brainstem make this approach less indicated for lesions with major extension in the MCF and the anterior cavernous sinus.

Some ruptured intracranial aneurysms concomitant with major artery occlusion may not be amenable for standard clipping or coiling due to the specific hemodynamic conditions. The long-term effect of flow reduction therapy for such aneurysms is largely unknown. ⋯ All the possible treatment options should be carefully assessed because the long-term effect of the flow alternation method to prevent rebleeding has not been proved. However, our case suggests that the strategy of reducing the hemodynamic stress at the parent artery may be effective even in selected cases of ruptured aneurysms for which standard clipping or coiling is not feasible.
