Objective: This project aimed to assess the information contained on general psychiatry program websites and identify common themes that may be useful and informative for residency applicants.

Methods: A survey study design was used to evaluate all US general psychiatry program websites as listed in the FREIDA database. The evaluation form included 44 binary (yes or no) items.

Background And Importance: The use of intravenous recombinant tissue plasminogen activator (IV rtPA) has become an integral part of modern acute ischemic stroke management; however, its use has been associated with the development of intracranial hemorrhage in 6.4% of patients. It is possible that underlying and unsuspected vascular lesions, such as cerebral aneurysms, may lead to intracranial hemorrhage after IV rtPA thrombolysis.

Introduction: As the medical treatment for human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) continues to advance, the HIV-related aneurysms may pose a clinical problem of increasing magnitude. The authors report on a successfully treated ruptured mycotic intracavernous carotid artery aneurysm case in an AIDS patient.

Methods: This 41-year-old AIDS patient presented with severe epistaxis.

Object: The authors studied the microsurgical anatomy of the ophthalmic artery (OphA), paying particular attention to its possibly dangerous anastomoses with the middle meningeal artery (MMA).

Methods: The microsurgical anatomy of the OphA and its anastomoses with the MMA were studied in 14 vessels from seven adult cadaveric heads. The origination order of the OphA branches varies in relation to whether the artery, along its intraorbital course, crosses above or below the optic nerve (ON).

Object: The aim of this study was to analyze the therapeutic decision-making process and outcome in 100 consecutive patients with aneurysmal subarachnoid hemorrhage (SAH) treated since the completion of the International Subarachnoid Aneurysm Trial (ISAT). All patients were evaluated and treated by a neurosurgeon with subspecialty training in both cerebrovascular and neuroendovascular surgery.

Methods: One hundred consecutive patients with aneurysmal SAH who had been admitted within 1 week posthemorrhage and who had been treated using either surgical clip application or endovascular coil embolization were included in this analysis.

Objective: We performed a systematic microanatomical study of the occipital artery (OA) and its branches to describe the course, diameter, and branches of this vessel as well as the presence and pattern of anastomotic channels between the OA and the vertebral artery.

Methods: Twelve occipital arteries (6 adult cadaveric heads injected with colored latex) were studied using the surgical microscope. Particular attention was given to the course and branching pattern of the artery as well as the presence and type of anastomotic channels between the occipital artery and vertebral artery.

Objective And Importance: Basilar artery occlusion is a clinical event with an exceedingly high mortality rate. Improved survival is closely associated with successful recanalization of the occluded basilar artery. Bilateral vertebral artery occlusion (BVAO) is a unique disease entity that effectively denies any direct access to the basilar artery for endovascular rescue therapy.

Introduction: Carotid Blowout Syndrome (CBS) carries an exceedingly high mortality rate. Various established endovascular techniques are successful in treating less acute CBS, but exsanguinating patients with hemodynamic compromise continue to pose a significant clinical challenge.

Methods: We report a 53-year-old male with squamous cell carcinoma of the anterior tongue presented with a sentinel hemoptysis followed by a massive oral hemorrhage.

Endovascular techniques for the treatment of intracranial aneurysms are rapidly evolving. Modifications of more traditional coils have been introduced. Such modifications include newer coils coated with various polymers to increase both coil thrombogenicity and degree of aneurysm packing.

Objective And Importance: As endovascular neurointerventions continue to evolve rapidly, angioplasty and stenting of both the extracranial and intracranial vessels have become more routine procedures. When the transfemoral approach is contraindicated or technically difficult, familiarity with alternative access techniques becomes essential. We report a successful transaxillary carotid stenting in a patient with an axillary bifemoral bypass graft.

The endovascular treatment of intracranial aneurysms has recently become an established therapeutic option. The foundation of this treatment modality was laid by the work done in ground-breaking cases, combined with technological advances since the first half of the 19th century. In this historical overview the authors describe the steps taken by the early pioneers and the results of their work, which was often done under challenging circumstances.

The management of unruptured cerebral aneurysm is controversial. Because the natural history of unruptured cerebral aneurysm is not well defined, the best management strategy is unclear. The current consensus on the management of unruptured cerebral aneurysm includes observation, microsurgical clipping, and endovascular treatment.

The etiopathogenesis of traumatic spinal subdural hematoma (SSH) is uncertain. Unlike the supratentorial subdural space, no bridging veins traverse the spinal subdural space. The authors describe a case of subacute SSH that occurred after spontaneous resolution of traumatic intracranial SDH and suggest a causal relationship between the two.

Endovascular treatment of aneurysms has only recently become an accepted therapeutic modality. Nonetheless, treatment of aneurysms with the aid of various foreign bodies such as needle and wire insertion with or without electrical current has been reported since the first half of the 19th century. In 1832 Phillips induced clot formation in the femoral and carotid arteries of dogs by leaving needles in the arteries for variable lengths of time.

Object: The prognosis of patients with acute symptomatic cervical internal carotid artery (ICA) occlusion is generally considered to be poor. Traditionally, such patients are not considered eligible for urgent thrombolytic/endovascular treatment. Since 1998, an aggressive therapeutic approach with endovascular treatment has been adopted at the authors' institution.

Temporary occlusion of large vessels (the Matas test) to test the adequacy of collateral circulation is part of daily clinical practice. Nevertheless, only a few clinicians are aware of Rudolph Matas and his pioneering work in different fields of medicine. A legendary New Orleans surgeon, Rudolph Matas (1860-1957) lived nearly a century.
