Can the degree of coronary collateralization be used in clinical routine as a valid angiographic parameter of viability?

The success rate of percutaneous coronary artery intervention (PCI) of chronic total occlusion (CTO) lesions have increased in the recent years. However, improvement of function is only possible when significant myocardial viability is present. One of the most important factors of maintaining myocardial viability is the opening and development of collaterals.

Endovascular treatment of unruptured aneurysms of cavernous and ophthalmic segment of internal carotid artery with flow diverter device Pipeline.

Background: Intra-arterial treatment of aneurysms by redirecting blood flow is a newer method. The redirection is based on a significantly more densely braided wire stent. The stent wall keeps the blood in the lumen of the stent and slows down the turbulent flow in the aneurysms.

Endovascular versus operative treatment of cerebral aneurysms: a comparison of results from a low-volume neurosurgical centre.

Background: Subarachnoid haemorrhage is a debilitating disease. The treatment options include surgical clipping or endovascular embolisation. Still, many controversies exist about which method is more convenient.

Treatment of tongue cavernous haemangioma with direct puncture and sclerotization with ethanol.

Background: Haemangiomas of tongue are rare type of malformations. They can be treated mostly conservatively but in some cases they need more aggressive treatment with preoperative intra arterial embolization and surgical resection. Lesions of tongue that are localized superficially can also be treated with direct puncture and injection of sclerosing agent (absolute ethanol).

Embolization of spinal dural arteriovenous fistula via the retrocorporeal artery: case report.

Background And Importance: The goal of spinal dural arteriovenous fistula (DAVF) treatment is to permanently occlude the proximal draining vein and the fistula itself, which can be achieved by open surgery or endovascular treatment. The endovascular approach is currently the primary treatment, but it requires the presence of an access as close to the site of the fistula as possible. This case illustrates that the retrocorporeal artery may be an alternative option in case of previous embolization failure with proximal occlusion of the radicular arteries.

Quantitative evaluation of the tibial tunnel after anterior cruciate ligament reconstruction using diffusion weighted and dynamic contrast enhanced MRI: a follow-up feasibility study.

Objective: The aim of the study was to evaluate the feasibility of two quantitative MRI methods: diffusion weighted imaging (DWI) and dynamic contrast enhanced imaging (DCEI), for follow-up assessment of the tibial tunnel after reconstruction of the anterior cruciate ligament (ACL).

Materials And Methods: Twenty-three patients were examined by MRI at 1 and 6 months following ACL reconstruction. DWI and DCEI were utilized for evaluating the region of interest (ROI) within the proximal part of the tibial tunnel.

Adult metachromatic leukodystrophy: a new mutation in the schizophrenia-like phenotype with early neurological signs.

Objectives: The adult type of metachromatic leukodystrophy can manifest itself as motor or as psycho-cognitive form, the latter is very similar to schizophrenia. We report on two sisters with adult metachromatic leukodystrophy who display symptoms of both forms.

Methods: Presented are genotype analyses and 4-year follow-up data regarding clinical manifestations as well as neurocognitive and neuroimaging results for two adult sisters with metachromatic leukodystrophy.

Endovascular treatment of a direct post-traumatic carotid-cavernous fistula with electrolytically detachable coils.

Carotid-cavernous fistulae are abnormal communications between the internal carotid artery and venous compartments of the cavernous sinus. Fistulae are uncommon but well-documented sequelae of craniofacial trauma. The characteristic clinical presentation includes ocular pain, chemosis, exophthalmus and visual disturbances.

Treatment of ruptured intracranial aneurysms: report from a low-volume center.

Background: The aim of this retrospective analysis was to present our experience and results in treating subarachnoid hemorrhage due to ruptured intracranial aneurysms at a neurosurgical department with a small annual number of cases (i.e. a low-volume center) and to discover which factors could influence treatment and reliably predict the outcome of hemorrhage.

Recurrent giant invasive thoracolumbar schwannoma.

Giant invasive spinal schwannoma is a new term proposed by Sridhar in 2001 for a particularly aggressive type of benign spinal schwannoma. Only a few cases have been published, the majority of these located in the lumbosacral spine, two in the thoracic and only one in the cervical spine. A rare case of such a tumor is presented.

Endovascular treatment of arteriovenous malformation in a child.

Arteriovenous malformations are direct communications between the arterial and venous circulations without the usual passage through the capillary net. They are the most frequent type of malformations of the intracranial circulation and the second most frequent cause of intracranial hematomas or hemorrhage. We report on a 7-year-old girl with intracerebral hematoma following acute rupture of an arteriovenous malformation.

[Endovascular treatment of intracranial artery aneurysms in the posterior cerebral circulation].

The purpose of the study was to determine the safety and effectiveness of electrolytically detachable platinum coils in the endovascular treatment of ruptured and unruptured aneurysms in the posterior cerebral circulation. The aneurysms were occluded with electrolytically detachable platinum coils. Six patients with posterior cerebral circulation aneurysms were treated.
