: A concha non-pneumatized sphenoid is considered to be a contraindication for the transsphenoidal resection of a pituitary adenoma. Specifically, this anatomical variation makes it difficult to approach the sella turcica. However, in this report, an intra-operative navigational system was used as a guide to access the sella through the sphenoid sinus. This procedure was found to be both reasonable and safe....

OBJECTIVES: The incidence of giant aneurysms in the paraclinoid section of the internal carotid artery (ICA) is low. They manifest their occurrence by subarachnoid haemorrhage and neurological and hormonal symptoms, resulting from compression on either the nervous structures or on the pituitary. The treatment of these aneurysms is a challenge for the surgeon, due to a difficult access, high operational risk and when the size of operated malformations is large.

MATERIAL AND METHODS: Between the years 1994 and 2001, twenty (20) patients with giant paraclinoid aneurysms of the carotid artery were submitted to: endovascular treatment - 7 patients and to microsurgery - 13 patients. The treatment, following the access to the aneurysm and consisting in short-time (temporary) endovascular occlusion of ICA, was applied in some cases, while trapping was the method of choice in other cases.

RESULTS: Good results of the endovascular treatment were obtained in 6 patients and, in one (1) case, satisfactory result was observed. Regarding the whole study group, hormonal symptoms (amenorrhoea) occurred in one case only. Four aneurysms were totally embolized, 1 - almost totally and 2 - partially. Recanalisation was observed in one case after 2 years. In the surgical method, good and very good results were obtained in 10 patients and satisfactory results - in 3 patients.

CONCLUSION: Application of either the endovascular method or of the microsurgical method - or of both these methods - used individually in case of a given aneurysm, increases the chances for an effective occlusion with a lower operative risk....

: Our controlled case describes the drug possibility to stabilize the exudative form of Age-related Macular Degeneration. The new approach of selective destruction of choroidal neovascularization (CNV) can be applied in patients with subfoveal lesions. Photodynamic therapy (PDT) is based on the reaction of photoactivable drug with the light of low-energy laser beam. So far only verteporfin [Visudyne, Novartis] as sensitizer is marketed and laser with wavelength of 689 nm is used. But it is questionable whether to apply this very costly treatment to extremely old people. An example of treatment of 90-year old woman with AMD with classic form of CNV is presented. Her BCVA was 0.05 OD. She underwent four session of PDT. At the last visit (eighteen months after initial and ten months after last session of PDT) the BCVA remained 0.05 OD. The patient is using a special magnifying lens for reading achieving near vision of 0.32. The presented example indicates the necessity of detailed study of every case to promote the therapeutic decisions for the benefit of progress in the field....
