ABSTRACT

BACKROUND: Stroke is a frequent disorder in patients with an antiphospholipid syndrome (APS). Due to a high risk for further thromboembolic events, appropriate anticoagulation therapy in patients with an APS-associated stroke seems mandatory but drug eluting and duration is a matter of debate. CASE: A 48-year-old female patient presented with Broca's aphasia and mild hemiparesis on the right side. Diagnostic work-up revealed left middle cerebral artery (MCA) occlusion yet without diffusion-weighted lesions. Due to a thrombocytopenia (67.00 g/l) systemic thrombolysis was not indicated and endovascular treatment was initiated 150 min after symptom onset. After successful clot retrieval, recurrent re-occlusions lead to the necessity of stent implantation and anticoagulation, respectively. On day 5 she developed a new severe right-sided hemiparesis. The magnetic resonance imaging (MRI) showed a subtotal restenosis of the left MCA despite the regular anticoagulation regime leading to a new left MCA ischaemic stroke. In the meantime, the unknown aetiology, the patients' age and the thrombocytopenia let to further diagnostic workup. Elevated blood parameters such as lupus anticoagulant (LA)-1, LA-ratio, positive anti-nuclear antibody (ANA), p-anti-neutrophil cytoplasmic antibodies (ANCA), c-ANCA confirmed the diagnosis of APS. CONCLUSION: This case report showed the feasibility of mechanical clot retrieval and stent implantation in patients with APS. Due to the elevated risk of in-stent thrombosis a prolonged therapy with glycoprotein (GP)IIb/IIIa receptor antagonists in the initial postoperative period and further anticoagulation with coumarin derivate might be needed.

ABSTRACT

The three therapeutic modalities for arteriovenous malformation (AVM) treatment (surgery, embolization, and radiotherapy) developed in the past years with specific tools, each tool with its own qualities. Soon after the implementation of embolization for treatment of AVMs, this technique was used in combination with microsurgery; since the development of radiosurgery, treatment algorithms combining embolization with surgery and eventual subsequent radiosurgery, embolization with radiosurgery, or surgery with subsequent radiosurgery have been reported. These different combinations have been in use under the term multimodality treatment for many years, but the algorithms regarding the combination of tools, which tool has priority, and how the risk levels of each tool are assessed shows great variability among institutions. Centers with a surgical background see embolization as a technique to increase surgical feasibility and radiosurgery as a tool to complete subtotal AVM excision. Institutions with an endovascular background embolize AVMs with the aim of maximal occlusion rates and view surgery or radiosurgery as a technique to be used if the goal of total endovascular occlusion cannot be achieved. Radiosurgeons receive patients after incomplete embolization or surgical extirpation or a combination of both.
