- Torcular dural sinus malformations (tDSMs) with arteriovenous shunts are rare congenital intracranial vascular malformations that carry a high rate of neurologic impairment and death in the neonatal, infant and young pediatric population. Their impact on brain venous drainage, especially the deep venous system, is one of the key factors in the clinical prognosis and natural history of the disease. We describe our therapeutic strategy for tDSMs, disconnecting the reflux into the deep venous system by performing an endovascular straight sinus occlusion.MethodsAmong all children with dural sinus malformations seen between 2002 and 2020, we retrospectively reviewed those with tDSM in whom straight sinus occlusion had been performed.ResultsOur databank included nine patients with tDSM that were embolized. Mean age at the clinical onset was 8.9±9.6 months (min–max=0–31). Five patients presented a significant reflux in the straight sinus on digital subtraction angiography. Those patients were initially clinically worse (mean modified Rankin Scale (mRS) 3.8) than those who did not present with reflux (mean mRS 2.25), this reflux being responsible for intraventricular hemorrhage in three patients. The reflux was suppressed by transarterial embolization in one patient and by transvenous straight sinus occlusion in four patients. Staged endovascular treatment resulted in a complete cure in six patients without complications, and clinical improvement in all patients.ConclusionStraight sinus occlusion is a feasible technique that needs to be considered in the treatment strategy for tDSM with deep venous reflux in order to avoid or minimize brain damage.

- The arterial blood supply to the dura mater is rich, complex and is derived from both the internal and external carotid systems. Endovascular management of a variety of intracranial diseases necessitates a thorough understanding of the dural arterial network. In this article we review the normal contributions of the pial arteries to the blood supply of the dura mater and discuss some aspects of its role in the supply of dural arteriovenous shunts (DAVS).

- Posterior condylar canal dural arteriovenous fistulas (PCC DAVFs) are rare lesions that may present with pulse-synchronous bruit. In cases with venous reflux there is a risk of haemorrhage or even dementia. Diagnosis and endovascular treatment require a profound knowledge of the vascular anatomy of the craniocervical junction and comprehensive neurovascular imaging. We describe the clinical presentation, angiographic imaging and endovascular treatment of a PCC DAVF in a female patient with pulse-synchronous bruit as the presenting symptom. The fistula drained almost exclusively into the sigmoid sinus and internal jugular vein. There was no intracranial reflux. The PCC DAVF was treated with transvenous coil occlusion of the fistulous pouch in the condylar canal. Symptoms resolved immediately after intervention and the patient recovered quickly without any neurological deficits. MR angiography confirmed occlusion of the DAVF. The dural sinus was patent with normal blood flow.
