Introduction: Injury and subsequent thrombosis of the cerebral venous sinuses may be caused by closed head injuries secondary to a variety of different mechanisms. Skull fractures can lacerate or otherwise disrupt adjacent dural sinuses. The sequelae of such injuries may include thrombosis and either partial or total occlusion of the sinus, ultimately resulting in significant venous congestion. Sagittal sinus injury is associated with a more serious outcome due to the obligatory flow into the sinus, especially posterior to the coronal suture. In such cases, venous infarction may be a severe and life-threatening complication of head injury., Case Presentation: A 2-year-old female presented with a depressed skull fracture near the midline and a thrombus in the sagittal sinus. Anticoagulation, the standard treatment cerebral venous sinus thrombosis (CVST), was contraindicated due to intracranial hemorrhage, so immediate thrombectomy was performed with successful neurologic recovery at 9-month follow-up. To our knowledge, this case is the youngest patient documented to receive mechanical thrombectomy for superior sagittal sinus (SSS) thrombosis due to trauma., Conclusion: Closed head injuries in pediatric patients may be associated with CVST, with resulting venous drainage compromise and profound neurologic sequelae. Unlike adult patients with spontaneous CVST in which anticoagulation are the standard of care, pediatric patients experiencing traumatic CVST may have contraindications to anticoagulants. If the patient has a contraindication to anticoagulation such as intracranial bleeding, endovascular mechanical thrombectomy may be an effective intervention when performed by an experienced neurointerventionalist., (© 2024 The Author(s).

Brucellosis is one of the most common zoonosis worldwide. It is still endemic in many regions of the world. A 6-year-old female was admitted to the emergency department (ED) due to a sudden change in consciousness, urinary incontinence, vomiting, and difficulty in walking. Neurological examination demonstrated abducens nerve paralysis, mild-to-moderate motor deficit in hemiparesis in the left arm. Brain magnetic resonance imaging showed a hemorrhagic focus at the right frontal lobe and thrombosis in the superior sagittal sinus of the brain. The diagnosis of neurobrucellosis was confirmed by identifying Brucella spp. in the blood culture on the day 6 of pediatric intensive care unit admission; thus, trimethoprim-sulfamethoxazole and rifampicin, and ceftriaxone were promptly initiated. Despite neuroprotective management and acetazolamide, the patient's neurological problems and high intracranial pressure (ICP) persisted. An external ventricular drainage tube and a Codman ICP monitor were placed to be on the consent vigilance of the patient's neurological condition. The patient's ICP continued to increase despite the current treatment regimen; therefore, a decompressive bitemporal craniectomy was performed. The ICP level of the patient returned to its normal range immediately after the craniectomy. The patient did not have any notable neurologic sequelae at the first-year follow-up. Neurobrucellosis is a rare complication of systemic brucellosis and may present as meningitis, encephalitis, myelitis, radiculitis, and/or neuritis. Herein, we describe a six-year-old girl with brucellosis complicated with cerebral vein thrombosis. This case illustrates the need for close monitoring of patients with unexplained neurological signs or symptoms for brucellosis in endemic areas., Competing Interests: None declared., (Thieme.

Background: Cerebral venous sinus thrombosis (CVST) is a rare cause of stroke. Medical and neurointerventional strategies, such as in situ thrombolysis, are standard therapies. These techniques are insufficient when clinical deterioration arises from mass-associated effects and transtentorial herniation; in such cases, decompressive hemicraniectomy may be indicated. To the best of our knowledge, the association of open surgical thrombectomy with bilateral decompressive craniectomy has not been reported to date., Case Description: A 45-year-old woman presented with extensive cerebral venous sinus thrombosis that was resistant to anticoagulation and endovascular therapies. Her clinical condition deteriorated until she became comatose, and bilateral hemicraniectomy combined with open surgical thrombectomy through the superior sagittal sinus was indicated. Computed tomography angiography confirmed postoperative maintenance of sinus permeability. The patient's clinical status improved dramatically, and she had a favorable outcome, including recovery of her functional independence to perform all activities of daily living (modified Rankin Scale score = 0). The follow-up period was 5 years., Conclusions: Open surgical thrombectomy combined with decompressive craniectomy is a lifesaving procedure that can lead to favorable outcome and should be considered for treatment of refractory malignant cerebral venous sinus thrombosis., (Copyright © 2018 Elsevier Inc.

Background: Sinus pericranii (SP) is a rare venous anomaly involving an abnormal connection of the intracranial dural sinuses with the extracranial veins. Magnetic resonance (MR) imaging (MRI) with MR venography can detect the typically congested intra- and extracranial venous components of SP., Clinical Presentation: We report a rare case of lateral SP associated with the superior sagittal sinus, which might had already developed almost total thrombosis of the SP at the first MRI. As this patient had not presented with classical manifestations of SP on clinical or neuroradiological findings, the initial diagnosis of SP was difficult. Repeated MRI revealed dynamic morphological changes associated with reperfusion of the thrombosed SP via the cortical vein., Conclusion: MR venography combined with gadolinium enhancement was useful for diagnosis of the SP with an extremely slow flow status.

A patient with nonsyndromic Kleeblattschädel, who underwent a craniotomy involving a constricting calvarial ring and frontal calvarial remodeling, developed a superior sagittal sinus thrombosis. The superior sagittal sinus venous outflow was obstructed as a consequence of the rapid brain expansion, along with a conflict of a remaining posterior bone crest. A successful second operation was performed to remove the posterior bone crest and facilitate the venous outflow. Meticulous preoperative planning should be carried out before addressing this complex craniofacial deformity.

We present a young woman with rapidly progressive neurologic decline in the setting of malignant cerebral edema due to extensive superior sagittal sinus thrombosis and cortical venous thrombosis despite intravenous heparin administration. Complete revascularization of the occluded sinus was achieved using suction thrombectomy with the 5 max Penumbra catheter in combination with the Solitaire FR clot retrieval device. The successful endovascular treatment halted the progression of her cerebral edema, and the patient eventually had an excellent recovery after prolonged intensive medical therapy. To our knowledge, this is the first reported case describing such a combined mechanical approach for cerebral venous sinus thrombosis. The clot retrieval properties of the Solitaire device combined with direct aspiration via the newest generation Penumbra catheters may allow more rapid, safe and efficient revascularization than all previously reported endovascular treatments for this potentially devastating condition.

Object: Intracranial hypertension resulting from compression of the superior sagittal sinus (SSS) by an overlying depressed calvarial fracture is a rare condition. Primary surgical treatment for the symptomatic patient in this setting traditionally involves elevation of the fracture, which often carries significant associated morbidity., Methods: The authors report a case involving a 6-year-old boy who suffered a closed, depressed, parietooccipital fracture as the result of an unhelmeted all-terrain vehicle accident. This fracture caused compression and subsequent thrombosis of the SSS, which resulted in CSF malabsorption and progressive intracranial hypertension. Initially headache free following the injury, he had developed severe and unremitting headaches by postinjury Day 7. A CT angiography study of the head obtained at this time exhibited thrombosis of the SSS underlying the depressed calvarial fracture. Subsequent lumbar puncture demonstrated markedly elevated intrathecal pressures. Large volumes of CSF were removed, with temporary improvement in symptoms. After medical management with anticoagulation failed, the decision was made to proceed with image-guided ventriculoperitoneal shunt insertion., Results: The patient's headaches resolved immediately following the procedure, and anticoagulation therapy was reinstituted. Follow-up images obtained 4 months after the injury demonstrated evidence of resolution of the depressed fracture, with recanalization of the SSS. The anticoagulation therapy was then discontinued. To the authors' knowledge, this report is the first description of ventriculoperitoneal shunt insertion as the primary treatment of this infrequent condition., Conclusions: This report demonstrates that select patients with this presentation can undergo CSF diversion in lieu of elevation of the depressed skull fracture-a surgical procedure shown to be associated with increased risks when the depressed fracture overlies the posterior SSS. The literature on this topic is reviewed and management of this condition is discussed.

Objective: Tuberculosis affects the central nervous system in various ways but has not been reported to cause venous sinus thrombosis. In this case report, extensive calvarial tuberculosis caused compression and occlusion of the superior sagittal sinus in an adult man. Early diagnosis combined with surgical and medical treatment resulted in cure of the disease., Clinical Presentation: A 34-year-old man presented with a nonhealing sinus in the frontal area after a trivial injury without any neurological deficits or features of raised intracranial pressure. Magnetic resonance imaging scans showed evidence of extensive bilateral extradural granulations, bone destruction, and thrombosis of the anterior half of superior sagittal sinus., Intervention: The affected bone and extradural granulations were surgically excised. Histopathology showed tuberculous osteomyelitis, and the patient received anti-tuberculous treatment, after which he had a good recovery., Conclusion: Calvarial tuberculosis as a cause of sagittal sinus thrombosis is a rare condition and is reported here for the first time, to our knowledge. Surgical excision of the compressing granulations followed by medical treatment is curative without sequelae if the intervention is performed before the disease extends intradurally.

The great variability of clinical appearance is one of the main features of superior sagittal sinus thrombosis. However, hydrocephalus associated with cerebral sinus thrombosis is rare. We report on a patient presented with thunderclap headache, accompanied by nausea, vomiting, and drowsiness. Lumbar puncture ruled out subarachnoid hemorrhage, whereas CT revealed marked hydrocephalus. In addition, magnetic resonance venography then confirmed the diagnosis of cerebral sinus thrombosis. It is a rare occurrence but clinically important, since it entails disastrous sequels if unrecognized, and hydrocephalus is treated in the usual fashion with ventricular drainage.

Background and Purpose: Cerebral venous thrombosis is a rare entity that can be difficult to manage. Intrasinus thrombolysis is an increasingly applied intervention, but this modality carries an increased risk of hemorrhage. We describe for the first time an option with a potentially lower incidence of intracranial bleeding, the combination of the AngioJet rheolytic thrombectomy catheter with intra-arterial thrombolysis, in 2 patients with extensive dural sinus thromboses, preexisting intracranial hemorrhage, and severe progressive neurological deficits despite heparin therapy., Methods: Four procedures were performed in 2 patients with thromboses in the superior sagittal and transverse sinuses (right in 1 patient and bilateral in 1 patient) and cortical veins. Rheolytic thrombectomy was performed in the sigmoid, transverse, straight, and superior sagittal sinuses; this technique involves the use of the Bernoulli effect to create a vacuum that fragments and aspirates thrombus. For associated persistent cortical vein thromboses, low-dose intra-arterial thrombolysis was used., Results: Both patients had excellent angiographic results with sinus reopening after rheolytic thrombectomy and cortical vein reopening after intra-arterial thrombolysis. Follow-up CT showed no change in 1 patient and increased preexisting intracranial hemorrhage in the other. One patient had a negative hypercoagulable workup, and the other patient had probable anti-phospholipid antibody syndrome. At 6 months, both patients had excellent clinical outcome with no neurological deficits except mild short-term memory loss in 1 patient., Conclusions: The combination of rheolytic thrombectomy with intra-arterial thrombolysis is a treatment modality that allows accelerated recanalization of occluded dural sinuses and cerebral veins with lower doses of thrombolytic agents.
