Diode laser-assisted carotid bypass surgery: an experimental study with morphological and immunohistochemical evaluations.

Objective: Conventional suturing methods of microvascular anastomosis are associated with various degrees of vascular wall damage that can lead to thrombosis and bypass occlusion. An experimental model of double end-to-side venous graft anastomosis on the common carotid artery was set up to compare conventional suturing methods with a low-power diode laser vascular welding technique.

Methods: The experiments were performed on 40 rabbits that underwent implantation of a 15-mm segment of jugular vein on the common carotid artery.

Treatment of intracranial aneurysms.

The management of intracranial aneurysms (IAs) remarkably improved due to the development of diagnostic and surgical procedures. Subarachnoid hemorrhage (SAH) from IA rupture constitutes a devastating event, whose prognosis remains unsatisfactory. At present, several researchs are targeted to individuate subjects harboring unruptured IAs and those presenting a higher risk for rupture.

Cavernous hemangioma extending to extracranial, intracranial, and orbital regions. Case report.

Extraaxial cavernous hemangiomas are rare intracranial lesions that can be located in different cranial compartments. Extension across different tissue planes such as the subcutaneous tissue, skull, orbital cavity, intracranial dura mater, and extracranial trigeminal divisions within the same patient has not been previously reported. This 32-year-old woman suffered left exophthalmos, left sixth nerve palsy, and trigeminal neuropathy.
