A control angiogram showed resolution of the thrombus (Fig 1D) without evidence of distal thromboembolism. low-dose, intra-arterial abciximab infusion can immediately dissolve an acute thrombus that forms during intracranial aneurysm coil placement. Although neither the optimal dose of intra-arterial abciximab nor the need to supplement the intra-arterial infusion with intravenous administration was established, we preliminarily found that low-dose intra-arterial abciximab infusion may be relatively effective and safe in this setting, even in patients with acute subarachnoid hemorrhage. Thromboembolism is the most common source of periprocedural morbidity from the treatment of intracranial aneurysms with detachable coils. The approximated occurrence of thromboembolism is within the number of 3C10%, with long term deficits approximated that occurs in 3C5% of individuals (1C5). Among the sources of thromboembolism, thrombus development in the coilCparent artery user interface can be a potential main problem and poses cure dilemma, especially in the establishing of the ruptured aneurysm (6). Today’s endovascular administration of severe thrombus formation during intracranial aneurysm coil positioning includes treatment with hypervolemia; improved intravenous heparin; postprocedural and periprocedural administration of antiplatelet real estate agents; intra-arterial thrombolysis with urokinase or cells plasminogen activator (t-PA); and, recently, intravenous bolus administration and infusion of powerful glycoprotein IIB-IIIA inhibitors such as for example ReoPro (abciximab; Eli Lilly, Indianapolis, IN) (6C10). Better regimens are had a need to regard this devastating problem potentially. The usage of thrombolytics such as for example urokinase and t-PA in individuals with aneurysmal subarachnoid hemorrhage can be controversial, particularly provided the documented threat of fatal intracranial rehemorrhage (8). Case reviews have described the usage of an intravenous bolus and infusion of glycoprotein IIB-IIIA inhibitor abciximab as salvage therapy for thrombus development during intracranial coil positioning in unruptured aneurysms (7, 9, 10). Nevertheless, intravenous dosages of abciximab, like the suggested 12-hour infusion using its long term half-life, escalates the threat of the bleeding problems considerably, both and systemically intracranially; this approach is not advocated for ruptured aneurysms (6, 11C13). Specifically, if pre-existing infarcted areas can be found, they may raise the threat of intracranial bleeding further. We report some seven instances (four ruptured aneurysms, three unruptured) where thrombus shaped during intracranial aneurysm coil positioning. In each full case, the principal treatment was low-dose intra-arterial abciximab. Preliminary angiographic outcomes and medical outcomes were examined. Strategies We retrospectively evaluated the final 100 consecutive individuals (analyzed between November 2002 and Sept 2003) with an intracranial aneurysm who have been treated with coil embolization at our organization. Seven individuals were determined by looking and looking at the operative information in our data source for the keywords or em clot /em . The individuals included five ladies and two males older 45C71 years, four of whom got ruptured aneurysms, who got severe thrombus formation through the coil-placement treatment (Table).
