Tamponade Effect

Background: Parasagittal meningioma is a common type of intracranial meningiomas. Surgical resection of such lesions can result in injury to superior sagittal sinus. In rare occasions, extended craniotomy might be required for uncontrollable hemorrhage from a lacerated venous wall. Objective: In order to avoid extended craniotomy, we attempted a surgical technique that would provide more sustained control over the lacerated venous sinus. Method: A 56 year old lady underwent surgical resection for parasagittal meningioma. The lateral wall of the superior sagittal sinus was preached while scraping the tumor capsule from the sinus wall. Owing to difficulty in controlling the bleeding site, a tack up falx-assisted tension suture was attempted with a mass of Gelfoam and Surgicel over the laceration. Results: Adequate control for the venous sinus laceration. Conclusion: The falx-assisted suturing technique is quick, easy to perform and efficient in maintaining a constant tamponade effect over the lacerated site. We highly recommend such technique prior to extending the craniotomy over an injured venous sinus.

Object Radical removal of meningiomas involving the major dural sinuses remains controversial. In particular, whether the fragment invading the sinus must be resected and whether the venous system must be reconstructed continue to be issues of debate. In this paper the authors studied the effects, in terms of tumor recurrence rate as well as morbidity and mortality rates, of complete lesion removal including the invaded portion of the sinus and the consequences of restoring or not restoring the venous circulation. Methods The study consisted of 100 consecutive patients who had undergone surgery for meningiomas originating at the superior sagittal sinus in 92, the transverse sinus in five, and the confluence of sinuses in three. A simplified classification scheme based on the degree of sinus involvement was applied: Type I, lesion attachment to the outer surface of the sinus wall; Type II, tumor fragment inside the lateral recess; Type III, invasion of the ipsilateral wall; Type IV, invasion of the lateral wall and roof; and Types V and VI, complete sinus occlusion with or without one wall free, respectively. Lesions with Type I invasion were treated by peeling the outer layer of the sinus wall. In cases of sinus invasion Types II to VI, two strategies were used: a nonreconstructive (coagulation of the residual fragment or global resection) and a reconstructive one (suture, patch, or bypass). Gross-total tumor removal was achieved in 93% of cases, and sinus reconstruction was attempted in 45 (65%) of the 69 cases with wall and lumen invasion. The recurrence rate in the study overall was 4%, with a follow-up period from 3 to 23 years (mean 8 years). The mortality rate was 3%, all cases due to brain swelling after en bloc resection of a Type VI meningioma without venous restoration. Eight patients—seven of whom harbored a lesion in the middle third portion of the superior sagittal sinus—had permanent neurological aggravation, likely due to local venous infarction. Six of these patients had not undergone a venous repair procedure. Conclusions The relatively low recurrence rate in the present study (4%) favors attempts at complete tumor removal, including the portion invading the sinus. The subgroup of patients without venous reconstruction displayed statistically significant clinical deterioration after surgery compared with the other subgroups (p = 0.02). According to this result, venous flow restoration seems justified when not too risky.

Dural Arteriovenous Fistulas

Transvenous embolization of venous compartments within the venous sinus wall was the method initially attempted for closing dural arteriovenous fistulas in 15 patients (22 sinuses). The venous channel, separate from the sinus lumen and located in the venous sinus wall, could be embolized in 6 lesions (3 patients), including 3 superior sagittal sinus fistulas, 2 transverse sinus fistulas, and 1 straight sinus fistula. This technique resulted in closure of the fistulas and preservation of sinus patency as well as immediate improvement of clinical symptoms. The embolizable venous compartment of the fistula within the venous sinus wall could be detected by preoperative angiography, magnetic resonance imaging, and intraoperative venography. This unique drainage of dural arteriovenous fistulas may develop concurrently with more obvious portions of the fistula. Transvenous embolization of these venous compartments can close the fistulas and normalize impaired sinus function.

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.

Clinical observation of the patient with parasagittal meningioma at the level of the middle third of the superior sagittal sinus and falx is presented. When such tumors are removed, the main task is to prevent damage to the parasagittal veins, the injury of which can cause a persistent neurological defi cit in the postoperative period. A feature of this case is the complex use of advanced minimally invasive methods of angiographic diagnosis when planning surgical treatment, which signifi cantly increases the chances of a successful outcome of the operation.

Parasagittal Meningioma

Pulmonary metastases of benign meningiomas are extremely rare. The case of a 34-year-old man with bilateral parasagittal meningioma who developed pulmonary metastases is described. The meningioma was an enormous hypervascular tumor with invasion of the superior sagittal sinus. The tumor was resected completely and histologically diagnosed as transitional meningioma. The Ki-67 labeling index was 5%. Four months after operation, the patient subsequently developed bilateral multiple lung lesions later identified as metastases. The lung lesions were partially removed surgically and histologically diagnosed as meningothelial meningioma WHO grade I. The Ki-67 labeling index was 2%. The histological findings demonstrated that the tumor occupied the arterial lumen and the perivascular space, suggesting that pulmonary tumors might metastasize via the vascular route. The histopathological features and mechanisms of metastasizing meningiomas are reviewed and discussed.

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.
