Subacute Thrombosis

Cerebral venous sinus thrombosis is an important pathology with various clinical symptoms. Early detection of thrombosis is very important for the improvement of the prognosis. The aim of this study was to calculate the diagnostic value of T2-weighted sequences of magnetic resonance imaging (MRI) in detecting subacute thrombosis. All patients that were suspected of having subacute cerebral venous sinus thrombosis and were referred to the emergency center of Kashani hospital (between September 2018 and September 2019) were entered into the study. Magnetic resonance venography (MRV) and T2-weighted MRI were accomplished for each patient. The sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) of MRI using MRV as the reference method were calculated. A total of 630 patients were entered into the study. A positive subacute venous sinus thrombosis was detected in the MRV of 53 patients; consequently, the sensitivity of 60%, the specificity of 80%, the PPV of 21%, and the NPV of 96% were calculated. MRI was highly specific for detecting the subacute thrombosis of superior sagittal sinus, transverse sinuses, sigmoid sinuses, and straight sinus (specificity>94%). A substantial agreement was detected between MRI and MRV in distinguishing thrombosis of superior sagittal sinus, transverse sinuses, sigmoid sinuses, and straight sinus (kappa>0.6). T2-weighted MRI is a specific method in detecting cerebral venous sinus thrombosis. In a patient with signs of thrombosis in the T2-weighted sequence, additional workups are highly suggested to rule out the pathology.

Introduction : Cerebral Venous Sinus Thrombosis (CVST) is a rare stroke with a wide range of symptomatology at presentation ranging from headache, focal weakness, and coma. Anticoagulation remains the mainstay of treatment. However, in a subset of patients endovascular treatment can be potentially beneficial. Here we describe the first clinical experience using the INARI FlowTriever system to treat a patient presented with focal weakness and found to have diffuse cerebral venous sinus thrombosis. Methods : Case report of CSVT treated with INARI FlowTriever system. Results : A 78‐year‐old female with past medical history of Autoimmune hepatitis and hypothyroidism, was brought to the hospital with left arm weakness. CT head revealed left temporoparietal intraparenchymal hemorrhage and right frontal subarachnoid hemorrhage. CTA of the head and neck revealed extensive CVST involving superior sagittal sinus, bilateral transverse and sigmoid sinuses. She was started on heparin drip. Patient was taken for venous thrombectomy due to persistent left‐sided weakness and multicompartment bleeding while being on anticoagulation for 48 hours. She underwent successful endovascular venous thrombectomy using the INARI FlowTriever system with large clot burden extracted. She was switched to novel oral anticoagulation prior to discharge. During the 3 months follow‐up–MRI brain with and without contrast revealed near complete resolution of the clot burden in the superior sagittal sinus and left transverse/sigmoid complex and her modified Rankin score was at 0. Conclusions : Here we discussed a case of diffuse CVST who was treated initially with heparin drip then underwent endovascular venous thrombectomy using INARI FlowTriever system with large clot burden aspirated with a reasonable safety profile. The INARI medical FlowTriever system is the only mechanical thrombectomy system indicated for the treatment of pulmonary embolism. It is specifically designed for venous clots. It is composed of a trackable large bore aspiration catheter. The INARI FlowTriever Catheter; has 3 expanding nitinol mesh disks; designed to engage and disrupt venous clots and subsequently deliver it to the large bore aspiration catheter. Its larger size makes it an attractive candidate for venous sinus clot retrieval. This study illustrates the first clinical use of INARI thrombectomy device in CVST with a reasonable safety profile. Anticoagulation is the mainstay first line treatment for CVST. However, a small subset of patients would potentially benefit from endovascular treatment but it still uncertain how to select these patients and what is the best timeline to offer early endovascular treatment. Various neuro endovascular techniques has been attempted to treat cerebral venous sinus thrombosis. However; it is unclear which approach and device provides the optimal restoration of venous blood flow. Current neuro endovascular techniques and devices are not particularly designed for CVST pathology treatment and there is need for further innovation and new devices.

Sagittal Sinus

Endovascular treatment for superior sagittal sinus (SSS) thrombosis is not always successful because of difficult access and long thrombus lesions. We report the first two cases of patients with acute cerebral venous sinus thrombosis at the SSS that was not recanalized by anticoagulation, mechanical thrombectomy, or thrombolysis, but was successfully treated by stent placement. Case 1 was a 37-year-old woman with bilateral subdural hematomas. Digital subtraction angiography showed obstruction of the sinus from the SSS to the right transverse sinus. Recanalization was achieved by selective thrombolysis using urokinase followed by balloon angioplasty, but re-occlusion occurred on the next day of treatment. Repeated endovascular treatment including balloon angioplasty, thrombus aspiration and thrombolysis using recombinant tissue plasminogen activator failed to achieve recanalization. We thus placed intracranial stents in the SSS, which did achieve recanalization. Case 2 was a 69-year-old woman with a small infarction in the left parietal lobe. Digital subtraction angiography showed sinus obliteration from the SSS to the bilateral transverse sinuses. Recanalization was not achieved by balloon angioplasty, thrombus aspiration and selective thrombolysis. We thus placed intracranial stents in the SSS, which did achieve recanalization. Postoperative course was uneventful in both cases and venous sinus patency was confirmed by venography >1.5 years after treatment. When conventional endovascular strategies have been unsuccessful, placement of intracranial stents, which can easily gain access to the distal part of the SSS as compared with carotid stents, may be a useful treatment option for the acute sinus thrombosis in this region.

The Impact

BackgroundCerebral venous sinus thrombosis (CVST) is an uncommon form of stroke with a variable presentation, ranging from headaches, to coma and death. Although the American Stroke Association has developed guidelines for the treatment of CVST, data are sparse on the outcome after treatment with anticoagulation, thrombolysis, and thrombectomy.MethodsIn this retrospective review, we describe the 5-year UC Davis experience with spontaneous CVST.ResultsForty-one patients (mean age 37.5±23.1, range 0–96 years; 29 female) were identified with CVST. The majority of cases involved the transverse sinus (75.6%), sigmoid sinus (58.5%), and superior sagittal sinus (29.3%). The most common form of treatment was anticoagulation or antiplatelet therapy (n=35), while six patients were managed by observation alone. The overall 1-year modified Rankin score (mRS) was 1.4±1.5. Male patients and patients with a poor admission mRS had a worse outcome. Outcome was unaffected by hypercoagulable state, number of dural sinuses involved, the presence of intracranial hemorrhage, or seizures. Two patients who underwent anticoagulation therapy also required endovascular thrombectomy; both patients had a 1-year mRS of ≤2. Two patients underwent direct open surgical canalization of the superior sagittal sinus with varying outcomes (mRS 2 vs mRS 6).ConclusionsIn our series, the majority (92.9%) of patients with spontaneous dural sinus thrombosis had a favorable clinical outcome as defined by a mRS ≤2. Further prospective studies are needed to study the impact of anticoagulation on the clinical course of the disease.

OBJECTIVEAlthough the majority of patients with cerebral venous sinus thrombosis (CVST) will improve with anticoagulation therapy, a portion of patients will either present in a comatose state or continue to deteriorate clinically despite early anticoagulation. In these cases, along with treating the underlying thrombophilia, timely thrombolysis may be beneficial. Repurposed arterial thrombectomy devices may not perform as expected in the cerebral venous sinus, and there are currently no preclinical endovascular thrombectomy (EVT) models for CVST. Contrary to arterial stroke research, preclinical models utilized to test various endovascular techniques and devices are lacking. The purpose of this research was to develop a reliable preclinical animal model for the testing of endovascular strategies to treat CVST.METHODSFive consecutive male Yorkshire swine weighing 45 kg were utilized. Thrombosis of the superior sagittal sinus was induced with a bovine thrombin injection via a microcatheter under distal balloon occlusion for 15 minutes. Combined arterial injections and superselective sinus injections confirmed the extent of thrombosis. EVT was subsequently performed using a second-generation stent retriever, followed by intravascular optical coherence tomography (OCT) imaging to assess the luminal environment after thrombectomy.RESULTSThrombosis of the superior sagittal sinus, EVT, and subsequent OCT imaging were technically successful in 4 of the 5 swine. Recanalization of the sinus with a second-generation stent retriever was successful after one attempt in 3 of 4 swine (75%), and 1 swine required two attempts. OCT imaging after thrombectomy revealed regions of residual sinus luminal thrombus despite complete angiographic recanalization. Thrombosed bridging cortical veins were also observed before draining into the sinus, along with patent cortical veins.CONCLUSIONSThe authors describe a preclinical model to assess endovascular techniques and devices for the treatment of CVST. Repurposed devices from arterial stroke may not perform as expected, given the unique features of venous sinus thrombosis. Residual bridging cortical vein thrombus and residual sinus thrombus, visualized on intravascular OCT, may be present despite complete sinus recanalization on angiography, and this may be the etiology of the poor clinical outcome despite technical success. In the setting of bridging cortical vein thrombus after successful sinus thrombectomy, direct chemical thrombolysis may be warranted to dissolve the remaining clot. This model may be helpful in developing and testing a new generation of devices designed specifically for CVST treatment.

We report a young man with a history of deep coma secondary to an extensive superior sagittal sinus thrombosis despite full systemic anticoagulation. Endovascular treatment combining a 5 Max ACE reperfusion catheter (Penumbra) and Solitaire (Covidien) retrieval device permitted revascularization of the superior sagittal sinus with restoration of anterograde venous flow. This treatment led to the disappearance of cytotoxic edema on MRI and to a neurological improvement with a modified Rankin scale score of 2 after two months. Our experience shows that this technique provides a useful and safe tool after failure of anticoagulation in cerebral venous sinus thrombosis.

Background: Although the mainstay of cerebral venous sinus thrombosis treatment is medical, rarely surgical intervention is warranted. We aimed to determine the role of prophylactic lumbo-peritoneal (LP) shunt in cases of CVST with papilledema.Methods: This is a retrospective review of 70 cases of CVST managed between November 2019 to April 2020. Indications for surgical management included poor response to medical management and severe vision impairment.Results: The mean age of the patients included in the study was 39.44±4.76 years. The most common presenting complaint was headache (83%) and nausea/vomiting (69%). On examination, the common findings were papilledema (57%), blurred vision (31%), double vision (21%) and hemiparesis (11%). Two cases had sudden loss of vision, who underwent emergency LP shunt surgery. Of the 40 cases with papilledema, 8 had severe papilledema. Based on MRI venography, transverse sinus was involved in half of all patients, superior sagittal sinus was involved in 29% and 21% had both the sinuses involved, while 7% had cortical vein thrombosis. Anticoagulants was the first line of therapy for the patients. Papilledema was present in 40 cases, of which 10 showed complete resolution of symptoms, 15 cases had reduced severity of symptoms and symptoms persisted in rest of the 15 cases. The 10 cases who had complete resolution of symptoms included two patients who underwent LP shunt. There were no deaths.Conclusions: We recommend that a LP shunt insertion in a patient with severe papilledema with superior sagittal sinus thrombosis can prevent disease progress, preserve vision and facilitate re-canalisation.

The superior sagittal sinus is the largest of the venous sinuses. It receives blood from the frontal, parietal, and occipital superior cerebral veins and the diploic veins, which communicate with the meningeal veins. The superior sagittal sinus drains into the transverse sinuses. Central nervous system tumors like meningioma, glomus tumor, and meduloblastoma, often directly compress the veins and sinuses of the brain. Major sites of the occlusion include superior sagittal sinus (SSS) and transverse sinus. Initial days cerebral venous sinus thrombosis (CVST) was diagnosed only on autopsy. Since the advent of modern investigative modalities like magnetic resonance Imaging (MRI), Computerised Tomography Angiography (CTA) and Magnetic Resonance Venography (MRV), more and more cases are being diagnosed confidently.

Intracranial Complications

Intracranial complications of sinusitis are rare but life threatening. We present a case of a 17-year-old woman with sinusitis who deteriorated over the course of 12 days from subdural empyema and global purulent cerebral venous sinus thrombosis. The patient was managed with surgery and mechanical thrombectomy utilizing a novel ‘stent anchor with mobile aspiration technique’, in which a Trevo stent retriever (Stryker) was anchored in the superior sagittal sinus (SSS) while a 5 MAX ACE reperfusion catheter (Penumbra) was passed back and forth from the SSS to the sigmoid sinus with resultant dramatic improvement in venous outflow. The patient was extubated on postoperative day 3 and was discharged with minimal lower extremity weakness on postoperative day 11. This is the first report using the Trevo stent retriever for sinus thrombosis. It is important to keep these rare complications in mind when evaluating patients with oral and facial infections.

Abstract BACKGROUND: Although the majority of patients with cerebral venous sinus thrombosis (CVST) obtain an optimistic clinical outcome after heparin or warfarin treatment, there remains a subgroup of patients who do not respond to conventional anticoagulation treatment. These patients, especially younger people, as documented by hospital-based studies, have a high morbidity and mortality rate. OBJECTIVE: To verify the safety and efficacy of a dual mechanical thrombectomy with thrombolysis treatment modality option in patients with severe CVST. METHODS: Fifty-two patients diagnosed with CVST were enrolled and treated with mechanical thrombectomy combined with thrombolysis. Patients underwent urokinase 100 to 1500 × 103 IU intravenous sinus injection via a jugular catheter after confirming diagnoses of CVST by using either magnetic resonance imaging/magnetic resonance venography or digital subtract angiography. Information obtained on the patients included recanalization status of venous sinuses as evaluated by magnetic resonance venography or digital subtract angiography at admission, during operation, and at 3- and 6-month follow-up after treatment. RESULTS: The percentage of patients that showed complete and partial recanalization were 87% and 6%, respectively, after mechanical thrombectomy combined with thrombolysis treatment; 8% of the patients showed no recanalization. The modified Rankin Scale scores were 1.0 ± 0.9, 0.85 ± 0.63, and 0.37 ± 0.53 for discharge, and 3- and 6-month follow-up, respectively. A total of 6 patients died despite receiving aggressive treatment. No cases of relapse occurred after 3 to 6 months of follow-up. CONCLUSION: Thrombectomy combined with thrombolysis is a safe and valid treatment modality to use in severe CVST cases or in intractable patients that have shown no adequate response to antithrombotic drugs.
