A three-year-old girl with an incidentally discovered infantile type of dural arteriovenous shunts (DAVs) along the superior sagittal sinus during investigation of a minor head trauma is presented. The DAVs drained into a developmental venous anomaly of the right cerebral hemisphere. In addition, there was a small cavernoma within the territory drained by the DVA. The patient underwent multiple transarterial embolizations to decrease the shunt flow and thus the constrained venous drainage of the DVA and right cerebral hemisphere. Pediatric dural arteriovenous shunts are a different entity from the adult type DAVs and should be managed according to the growth and development of the child. DVAs are extreme variations of the venous system with reduced flexibility to increased venous drainage. Regardless of the type of treatment employed, the DVA and its drainage pathway must be preserved.

Developmental venous anomaly (DVA) is a commonly encountered congenital abnormality of the venous drainage system. Spontaneous thrombosis of DVA is rare. We present a case of thrombosed brainstem DVA leading to venous infarction and oedema within the posterior fossa.A 49 year old, previously fit gentleman presented to the local hospital with a one day history of headache, slurred speech and incoordination. Examination demonstrated GCS of 13/15, cerebellar dysarthria, horizontal nystagmus to the left, mild right sided pyramidal weakness, right sided cerebellar ataxia and bilateral extensor plantars.CT venogram revealed a cerebellar DVA with thrombosis of one of the veins. There was surrounding venous infarction and oedema within the posterior fossa, causing compression of the fourth ventricle and dilatation of the lateral ventricles. MRI demonstrated extensive T2 change in the right cerebellar hemisphere, dorsal pons and right cerebral peduncle. No underlying thrombotic tendency was identified. He was treated successfully with intravenous heparin infusion. He improved over the next 3 weeks, and was discharged on warfarin with mild right sided ataxia and cerebellar dysarthria.Our case demonstrates that DVAs, generally considered as common insignificant anatomical variants, can uncommonly lead to significant complications.

Developmental venous anomalies (DVA) drain normal neural tissue and are mostly discovered incidentally. We describe a young patient with a left hemisphere superficial to deep DVA and right hemisphere venous outflow restriction presenting with a seizure. The right hemisphere drainage variation is not typical of a DVA but represents another drainage pattern on the border of normality.

A 40-year-old male suffered transient global amnesia and was diagnosed as having a very rare location of dural arteriovenous shunt (dAVS) involving the right sphenoparietal sinus. The feeding pedicles of dAVS were not only arising from the right external carotid system, including the middle meningeal artery, but also the right internal carotid system including the ophthalmic artery. The dAVS drained into the right sphenoparietal sinus, right vein of Labbe, and right basal vein of Rosenthal through numerous dilated temporal cortical veins. The arteriovenous shunt itself was located at the dura around the right superior ophthalmic fissure and a large varix received direct shunting blood flow from the right sphenoparietal sinus. The dAVS was cured by drainer clipping following transarterial embolisations. A dAVS with cortical venous drainage is considered to have a higher risk of haemorrhage and venous infarction than the others and thus warrants treatment even if the clinical symptom is minimal. If the dAVS has a single drainer, it will be easily cured by way of drainer clipping. Preoperative embolisation makes clipping easier and safer. Intraoperative angiography is useful because preoperative angiography may not necessarily show the complete angioarchitecture around the lesion.

Dural Arteriovenous Shunts

Pediatric dural arteriovenous shunts (dAVSs) are a rare form of vascular disease: Fewer than 100 cases are reported in PubMed and the understanding of pediatric dAVS is limited. For this study, we searched in PubMed, reviewed and summarized the literature related to pediatric dAVSs. Our review revealed that pediatric dAVSs have an unfavorable natural history: If left untreated, the majority of pediatric dAVSs deteriorate. In a widely accepted classification scheme developed by Lasjaunias et al., pediatric dAVSs are divided into three types: Dural sinus malformation (DMS) with dAVS, infantile dAVS (IDAVS) and adult-type dAVS (ADAVS). In general, the clinical manifestations of dAVS can be summarized as having symptoms due to high-flow arteriovenous shunts, symptoms from retrograde venous drainage, symptoms from cavernous sinus involvement and hydrocephalus, among other signs and symptoms. The pediatric dAVSs may be identified with several imaging techniques; however, the gold standard is digital subtraction angiography (DSA), which indicates unique anatomical details and hemodynamic features. Effectively treating pediatric dAVS is difficult and the prognosis is often unsatisfactory. Transarterial embolization with liquid embolic agents and coils is the treatment of choice for the safe stabilization and/or improvement of the symptoms of pediatric dAVS. In some cases, transumbilical arterial and transvenous approaches have been effective, and surgical resection is also an effective alternative in some cases. Nevertheless, pediatric dAVS can have an unsatisfactory prognosis, even when timely and appropriate treatment is administered; however, with the development of embolization materials and techniques, the potential for improved treatments and prognoses is increasing.

The smelling behavior of 52 right-handed subjects was videotaped during tasks involving identification and recognition of different odors. Analysis showed that men more often used the right nostril than the left whatever the odor. There was no significant difference for the women. These results support a more marked cerebral asymmetry in men than in women and a main involvement of the right cerebral hemisphere in the olfactory processes at least by right-handed men.

ABSTRACT The role of the right cerebral hemisphere (RH) associated with semantic priming effects (SPEs) must be better understood, since the consequences of RH damage on SPE are not yet well established. Objective: The aim of this article was to investigate studies analyzing SPEs in patients affected by stroke in the RH through a systematic review, verifying whether there are deficits in SPEs, and whether performance varies depending on the type of semantic processing evaluated or stimulus in the task. Methods: A search was conducted on the LILACS, PUBMED and PSYCINFO databases. Results: Out of the initial 27 studies identified, 11 remained in the review. Difficulties in SPEs were shown in five studies. Performance does not seem to vary depending on the type of processing, but on the type of stimulus used. Conclusion: This ability should be evaluated in individuals that have suffered a stroke in the RH in order to provide treatments that will contribute to their recovery.

We report a right-handed man who developed selective Kana (phonogram) agraphia following an infarct in the non-dominant right cerebral hemisphere. His ability for comprehension, reading and writing of Kanji (ideogram) was unaffected. Kana errors consisted of substitution with another letter and the number of target words was well preserved. The lesion responsible for his Kana agraphia included the right Wernicke's area (the posterior one-third or one-half of the superior temporal gyrus) on MRI, but he did not have aphasia. Based on these findings, we conclude that the language function in some dextral people may be partially lateralized to the right cerebral hemisphere.

Object The aim of this study was to assess the clinical efficacy of gamma knife surgery (GKS) in the treatment of dural arteriovenous shunts (DAVSs). Methods From a database of more than 1600 patients with intracranial arteriovenous shunts that had been treated with GKS, the authors retrospectively and prospectively identified 53 patients with 58 DAVSs from the period between 1978 and 2003. Four patients were lost to follow-up evaluation and were excluded from the series. Thus, this study is based on the remaining 49 patients with 52 DAVSs. Thirty-six of the shunts drained into the cortical venous system, either directly or indirectly, and 22 of these were associated with intracranial hemorrhage on patient presentation. The mean prescription radiation dose was 22 Gy (range 10–28 Gy). All patients underwent a clinical follow-up examination. In 41 cases of DAVS a follow-up angiography study was performed. At the 2-year follow-up visit, 28 cases (68%) had angiographically proven obliteration of the shunt and in another 10 cases (24%) there was significant flow regression. Three shunts remained unchanged. There was one immediate minor complication related to the administration of radiation. Furthermore, one patient had a radiation-induced complication 10 years after treatment, although she recovered completely. There was one posterior fossa bleed 2 months after radiosurgery; a hematoma, as well as a lesion, was evacuated, and the patient recovered uneventfully. A second patient had an asymptomatic occipital hemorrhage approximately 6 months postradiosurgery. The clinical outcome after GKS was significantly better than that in patients with naturally progressing shunts (p < 0.01, chi-square test); figures on the latter have been reported previously. Conclusions Gamma knife surgery is an effective treatment for DAVSs, with a low risk of complications. Major disadvantages of this therapy include the time elapsed before obliteration and the possibility that not all shunts will be obliterated. Cortical venous drainage from a DAVS, a risk factor for intracranial hemorrhage, is therefore a relative contraindication. Consequently, GKS can be used in the treatment of both benign DAVSs with subjectively intolerable bruit and aggressive DAVSs not responsive to endovascular treatment or surgery.

Transvenous Approach

The infantile dural arteriovenous shunts are multifocal involving different dural sinuses and progress to an occlusive venopathy with sigmoid sinus and/or jugular bulb stenosis and subsequent occlusion. We report a successful angioplasty and stent placement of a sigmoid sinus — jugular bulb stenosis due to venous occlusive disease in a patient with infantile dural arteriovenous shunts. A five-year-old patient presented with status epilepticus due to severe venous congestive encephalopathy. The angiogram revealed multifocal dural arteriovenous shunts, occlusion of the right sigmoid sinus, absence of cavernous sinuses and significant stenosis of the left sigmoid sinus — jugular bulb. By transvenous approach, percutaneous transluminal balloon angioplasty and stent placement of the stenosed left sigmoid sinus — jugular bulb segment was performed. This resulted in a significant decrease of the venous pressure gradient across the stenosis and allowed a dramatic clinical recovery. Dural sinus angioplasty and stent placement appears to be a safe and effective procedure and should be considered in the treatment of the venous occlusive disease associated with infantile dural arteriovenous shunts.
