Bilateral Transverse Sinus Angioplasty for the Treatment of Idiopathic Intracranial Hypertension ­ Case Report and Literature Review

Idiopathic intracranial hypertension (IIH) is a disease characterized by an increase in intracranial pressure, without presence of parenchymal lesions or hydrocephalus that justify it. Over 90% of cases there is association with stenosis of the dural venous sinuses. It is characterized by headache, tinidus, nausea, vomiting and visual disturbances. Initial treatment is clinical and when it fails there is indication of invasive procedures, among them shunts and fenestration of the optic nerve sheath. Angioplasty of dural venous sinuses, when indicated, has shown an alternative with better results and less complications. We report a case of a female patient, with 27 years old, diagnosed with IIH and bilateral transverse sinus stenosis, which was treated by bilateral stenting and total resolution of symptoms. Besides describing the case we review the literature about the subject.

Endovascular Neurosurgery in the Northern Macro-Region of Rio Grande do Sul: Part I

Introduction The city of Passo Fundo, in the north of the Rio Grande do Sul state, has been standing out in the health care field for many years. The state has become a reference in endovascular interventional neuroradiology. We will cover 10 years of experience in this area and divide our observations in 3 parts: cerebral angiograms (part I), carotid angioplasties (part II) and intracranial aneurysms (part III). The goal of part I is to statistically assess the cerebral angiograms, their indications, risks and complications, as well as to do a technical review. Materials and Methods A retrospective study from 2005 to 2015 with a total of 5,567 interventional neuroradiology procedures performed. A total of 4,114 angiograms, 639 embolizations of intracranial aneurysms, 414 carotid angioplasties, 143 embolizations of cerebral arteriovenous malformations, 32 embolizations of dural arteriovenous fistulas, 102 cerebral vasospasm treatments, 21 treatments of epistaxis, 36 embolizations of craniocervical tumor, 25 thrombolysis of ischemic stroke, 18 vertebroplasties and 13 embolizations of arteriovenous malformations of the face. Results A total of 4,084 procedures performed, 21,811 vessels studied, average vase 7.62/2.82 vessel and patient/procedure. Of these, 2,536 were diagnostic procedures and 1,548 angiographic controls. Of the total, 1,188 patients received only an angiogram, 27.14% of which were therapeutic procedures. We obtained a total of 3.89% complications: 2.33% reflection vasovagal, 0.56% allergic skin reaction, anaphylactic shock 0.07%, 0.27% femoral hematoma, 0.26% transient neurological deficit, 0.12% permanent neurological deficit and no case of death. Conclusion Cerebral angiography in adults, children and infants is a safe procedure with low risk of permanent neurological complications.

Hemorragia subaracnóide em criança de 7 meses: relato de caso / Subarachnoid hemorrhage a seven month-child: case report

Relatamos o caso de um menino de sete meses de idade com hemorragia intracraniana devido ao aneurisma roto na bifurcação da artéria cerebral média direita. Os aneurismas cerebrais são considerados raros em crianças, principalmente na primeira década de vida. Os autores discutem os achados clínicos e a patogênese dessa lesão.

Perfil dos diabéticos e hipertensos em Caseiros - RS / Profile of diabetics and hypertensive patients in Caseiros - RS

Deciciu-se estudar as características dos pacientes com Hipertensäo Arterial Sistêmica e Diabete Melito em Caseiros-RS. Foi utilizada uma amostra de 262 indivíduos avaliados numa Feira de Saúde do município. A amostra constou de 83 homens e 179 mulheres, sendo 47 hipertensos, 17 diabéticos (8 pacientes diabéticos eram também hipertensos) e os restantes 206 foram considerados como grupo controle. Os resultados do estudo indicam que a HAS prevaleceu nas mulheres a partir da 5ª década com obesidade de predomínio troncular e nos homens a partir da 6ª década com obesidade sem predomínio troncular. Todos os diabéticos eram obesos com distribuiçäo troncular prevalecendo na 6ª década
