Defect Diagnosis

Sinus pericranii (SP) is an uncommon and usually asymptomatic communication between intra- and extracranial venous drainage pathways in which blood flow can circulate bidirectionally through abnormal dilated veins through a skull defect. Diagnosis and evaluation of the venous drainage pattern is important if treatment is contemplated. Cerebral angiography with the use of Dyna CT can be helpful in the diagnosis of SP and its relationship with the skull defect. The authors report what is, to the best of their knowledge, the first case of SP treated by means of endovascular embolization with Onyx.

BACKGROUND: Cranioplasty is aimed to restore the structure and function of the lost portion of the skull defect. Many materials can be used for cranioplasty, such as the bones of the patient (autograft), the bones of other patients (allograft), bones of animals (xenograft), or synthetic materials such as acrylic or titanium mesh. These materials are quite expensive and sometimes require complex processes. Manual shaping of material for cranioplasty is also quite time-consuming and prone to cause esthetic dissatisfaction. The author will discuss the case of using polylactic acid (PLA) implant with 3-dimensional (3D) printing customization as a cheap and accurate cosmetic solution for cranioplasty procedures. CASE REPORT: We report 2 cases of skull defect underwent cranioplasty. The first case, female, 20-year-old, had a history of severe traumatic brain injury (TBI) and epidural hematoma. She underwent decompression craniotomy on the left frontotemporoparietal region of her skull. The second case, male, 46-year-old, had a history of spontaneous intracerebral hemorrhage due to arteriovenous malformation (AVM). He underwent decompression craniotomy on the right frontotemporoparietal region of her skull. Both the data of computerized tomography (CT) scan were reconstructed to get 3D model of skull defect. Prosthesis was made by 3D printer accordingly using PLA as material. There was no complication reported postoperatively and cosmetic satisfaction was obtained on both cases. CONCLUSION: The use of PLA implant with 3D printing customization was proved to be cost-effective and good cosmetic satisfaction with no complication reported following cranioplasty procedure.

AbstractThe mitral–aortic intervalvular fibrosa is an area of fibrous continuity between the mitral and aortic valves. We present the first case of a congenital pseudoaneurysm in this region, detected prenatally as an isolated cardiac defect, which was followed-up conservatively postnatally. The diagnosis was confirmed by echocardiogram demonstrating blood flow into the pouch during systole and into the left ventricular outflow tract during diastole. The infant has been followed-up with serial echocardiograms demonstrating stable size and appearance of the lesion, without signs of obstruction, making close continued observation a reasonable approach.

Dural arteriovenous fistulas (DAVFs) are abnormal connections between branches of the intracranial arteries and dural veins or sinuses. Advancements in the technique of endovascular embolization has made it the treatment of choice for DAVFs. The goal of treatment is to completely occlude the fistula orifice while maintaining the normal cerebral venous drainage. Depending on the site of the DAVF, endovascular treatment has its own challenges to the performing physician. In this case report, we will discuss complex anterior cranial fossa DAVFs, treatment approaches, and complications of the treatment.

Obstructed anomalous pulmonary venous return may masquerade clinically as persistent fetal circulation in newborns. Even after cardiac eterization has been performed, a similar conclusion could be reached if pulmonary blood flow is low in volume and pulmonary venous return is significantly delayed. To make the diagnosis by demonstrating the confluence of pulmonary veins by direct catheterization from the venous side may be difficult and can lead potentially to sudden deterioration by increasing the obstruction to venous return. We encountered these pitfalls in making the diagnosis of obstructed pulmonary venous return in a recent patient, which prompted this case report. CASE REPORT

Background: Reversible cerebral vasoconstriction syndrome (RCVS) has been associated with multiple medications, cocaine, pregnancy, migraine, and other conditions. Objectives: RCVS associated with interferon beta use has never before been described. Methods: We describe the case of a 20-year-old female who developed acute onset severe headache and was found to have subarachnoid hemorrhage 2 months after initiating Rebif (Interferon beta-1a) for multiple sclerosis (MS). Cerebral angiography showed multiple areas of distal stenosis and dilatation with radiographic resolution 1 month later. Results/conclusions: This is the first case report of RCVS in an MS patient treated with Rebif.

✓ Cranial dural arteriovenous fistulae (AVF's) of the tentorial incisura or the dura of the middle fossa have a much higher incidence of draining via leptomeningeal veins than do AVF's of the transverse-sigmoid sinuses or the cavernous sinus. Such a drainage pattern is associated with an increased incidence of intracranial hemorrhage and progressive focal neurological deficits. Patients with cranial dural AVF's often undergo surgical excision and/or endovascular embolization for elimination of the AVF. Since these lesions are frequently large and involve the skull base or adjacent dural sinuses, extensive surgery is often required. In contrast, spinal dural AVF's with only intradural venous drainage to the medullary venous system are treated successfully by simply interrupting the vein that drains the dural AVF as it enters the subarachnoid space. The authors identified a subgroup of patients with cranial dural AVF's in whom the AVF was drained only by leptomeningeal veins, and sought to establish whether simple interruption of the vein draining the blood from the AVF into the subarachnoid space is effective and lasting treatment in this subgroup of patients, as it is in patients with spinal dural AVF's. Four adult patients with symptomatic cranial dural AVF's (two petrotentorial, one middle fossa floor, and one posterior fossa base) were identified on arteriography as having fistulae that were supplied by the internal and/or external carotid arteries and drained only via leptomeningeal veins (two entered the petrosal vein, one a cerebellar hemispheric vein, and one a mesencephalic vein). All patients underwent interruption of the vein draining the dural AVF as it penetrated the dura to enter the subarachnoid space, and experienced neurological improvement after surgery. Repeat arteriography at 1 to 2 weeks (three patients), 3 months (3 patients), 12 to 15 months (three patients), and 4 years (two patients) revealed no residual AVF and no evidence of abnormal blood flow. Many cranial dural AVF's with leptomeningeal venous drainage (the type with the most aggressive behavior) are drained only by leptomeningeal veins. This subgroup of patients can be identified by selective arteriography and requires only interruption of the draining vein as it enters the subarachnoid space for successful, lasting elimination.

Pattern Presentation

Dural arteriovenous fistulas are unique vascular shunts that can be discovered incidentally or after presentation with pulsatile tinnitus, ocular symptoms, focal neurologic deficits, and even hemorrhage. Their natural history is predicated on the shunt’s venous drainage pattern; presentation modality and venous ectasia are also independent factors influencing lesion natural history. Their management is often via endovascular embolization; surgical disconnection of high risk fistulas and radiosurgery for low risk shunts unamenable to embolization are also options. This article will provide a modern update on dural arteriovenous fistula pathophysiology, natural history and treatment approaches.
