Endovascular Mechanical Thrombectomy

Objective Endovascular mechanical thrombectomy for the treatment of cerebral venous sinus thrombosis is not always successful. We present our experience of using self-expanding stents to facilitate effective recanalization of persistent lateral sinus thrombosis refractory to endovascular mechanical thrombectomy. Methods Data from patients who underwent endovascular mechanical thrombectomy for the treatment of acute symptomatic cerebral venous sinus thrombosis between August 2015 and July 2018 were evaluated. Patient demographics, procedural techniques, devices used and follow-up outcomes were assessed. Results A total of 14 patients underwent endovascular mechanical thrombectomy during the study period. Of these, stenting of the occluded sinus was performed in five patients with extensive sinus thrombosis after conventional endovascular mechanical thrombectomy. Three of the five patients had a variable degree of venous infarction and/or hemorrhage before treatment. The target lesion was located in the right lateral sinus in all five patients. Due to the length of the involved sinus, two stents were required in one patient and three stents in two patients. The only procedure-related complication was an asymptomatic tearing of the sinus wall in one patient. Stent patency could not be maintained in two patients due to stent buckling within the jugular foramen segment and an inability to maintain antiplatelet medication. Modified Rankin Scale scores at 2–16 months were zero in two patients, one in two patients, and five in one patient. Conclusions Stenting for the thrombotic occlusion of the lateral sinus is a feasible rescue method to overcome unsuccessful endovascular mechanical thrombectomy. However, currently available stenting systems may be unsuitable for use in the intracranial dural sinus system.

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.

Venous Sinus Thrombosis

Cerebral venous sinus thrombosis is a rare cause of stroke, which is routinely treated with systemic heparin. Unfavourable outcome is often seen in severe cases. Therefore alternative treatment methods should be explored in these patients. Due to the risk of haemorrhagic complications, treatment without administration of thrombolytics is of particular interest. This report presents a case of successful mechanical thrombectomy, without the use of thrombolytics, in a comatose patient with cerebral venous sinus thrombosis.

Aggressive Interventions

Anticoagulation with heparin is the current mainstay treatment for Cerebral Venous Sinus Thrombosis (CVST). Endovascular treatment is increasingly being used to treat patients with CVST who are non-responsive to anticoagulation. These more aggressive interventions include catheter-based local chemical thrombolysis, balloon angioplasty and mechanical thrombectomy with uncertain safety and efficacy. Here we describe the first reported clinical experience using the INARI FlowTriever system to treat a patient presented with focal weakness and found to have diffuse CVST.

Introduction : Patients with Cerebral Venous Sinus Thrombosis (CVT) are candidates for Endovascular Mechanical Thrombectomy (EMT) in cases of coma on presentation or clinical deterioration despite anticoagulation. We present two cases of CVT successfully treated with mechanical thrombectomy using Medtronic’s Solitaire Stent retriever. Methods : A retrospective review at a single center university hospital was performed for all cerebral venous sinus thrombosis case log from December 2018 to November 2020. Cases resistant to conventional medical therapy that underwent intrasinus stent retriever endovascular thrombectomy were noted. Results : Case 1: 26 year‐old male with a history of hypertension presented with 2 weeks of headaches, left sided numbness and blurriness of vision. Imaging revealed superior sagittal (SSS) and bilateral transverse sinus thrombosis. Patient was treated with heparin infusion and discharged home on oral apixaban. The following day he presented with new onset expressive aphasia. Imaging was unchanged. Due to worsening symptoms despite anticoagulation, Patient underwent mechanical thrombectomy using a stent retriever. Solitaire 6 × 40 mm stent was advanced and deployed through the microcatheter and retracted in the upper segment of posterior one third of SSS followed by alteplase infusion at 1 mg/hr (25 ml/hr) via Berenstein catheter for the next 36 hours. Intravenous heparin infusion was also started with aPTT goal 60–80. Cerebral angiogram was repeated two days later revealing successful recanalization of previously thrombosed SSS and bilateral transverse sinuses with significantly improved cerebral venous drainage. Patient was transitioned again to oral apixaban. Repeat CTA in 3 months showed significantly improved patency and recanalization. Case 2: A 42 year‐old male with history of ulcerative colitis presented with sudden onset right‐sided hemiparesis and hemisensory loss along with one month of headaches. Presenting NIHSS 14. Imaging revealed SSS thrombosis with thrombosis of the left transverse sinus complicated by left frontal intraparenchymal hemorrhage and subarachnoid hemorrhage. Patient underwent mechanical thrombectomy of SSS using Solitaire 6 × 40mm stent retriever with distal aspiration resulting in improved flow. Clinical course was complicated by seizures and acute respiratory distress syndrome requiring intubation followed by tracheostomy and G‐tube placement which were eventually removed during recovery. Patient was treated with high intensity heparin during his hospitalization and eventually transitioned to apixaban. Work up revealed protein S deficiency. Serial CT angiograms at 6 and 11 months revealed resolution of CVT. NIHSS improved to 1 with mRS of 2. Conclusions : These cases imply that intra‐cerebrovenous sinus mechanical thrombectomy with stent retrievers may be considered in patients with continuing worsening despite optimal medical management.
