Cerebral venous thrombosis (CVT) is a potentially serious disease, with nonspecific clinical symptoms and an unpredictable outcome. Despite adequate anticoagulation, a patient's clinical condition can rapidly deteriorate. The aim of this study was to evaluate the efficacy of local thrombolysis in these patients. Consecutive patients with progressive cerebral venous thrombosis between October 2008 and January 2011 were enrolled prospectively. Progressive CVT was defined as the persistence of neurologic findings (headache, blurred vision, and visual field defects) despite at least four days (or 48 hours in patients with involvement of more than one sinus) on full anticoagulation therapy with heparin and development of focal neurologic deficits or cortical hemorrhage. We excluded patients with large hematomas and predisposing malignancies like leukemia. All patients underwent local thrombolysis with 30 mg recombinant tissue plasminogen activator (rtPA). Overall, 26 patients were enrolled with a mean age of 35.5 years (range 18 to 56 years). Six patients (23%) were male and twenty patients (77%) were female. The most common presenting feature was headache and the most common neurologic finding was papilledema, which was present in all patients. Eighty-five percent of women had a history of oral contraceptive pill consumption. Successful recanalization was achieved in all patients except one (96.2%). Neurological examinations and follow-up assessments were based on a modified Rankin scale (mRS). Favorable outcome and recovery was defined as a mRS score of 0-1. Follow-up assessments at the third week showed that 25 out of 26 recovered, with 18 having a mRS score of 0 and 7 with a mRS score of 1. There were no procedure-related neurological complications. Our results show that local thrombolysis is a safe and effective treatment modality for patients suffering from progressive CVT.

We report the successful treatment of dissection with stenosis of the carotid artery by stenting and aspiration of hematoma. A male patient, presenting with acute blurred vision and weakness and numbness of the right side of his body, was diagnosed with common carotid artery (CCA) dissection and severe stenosis of the internal carotid artery and CCA by digital subtraction arteriography and color Doppler ultrasonography (CDU). Two stents were separately implanted into the left internal carotid artery and CCA to restore blood flow and seal the opening of the dissection. The hematoma inside the CCA dissection was transcutaneously aspirated under CDU guidance after thrombolysis with tissue plasminogen activator. Three days after the operation, the dissection was still sealed. The patient was discharged 1 week later without any signs or symptoms. Follow-up examination at 70 days confirmed complete healing of the CCA dissection. Transcutaneous intradissection hematoma aspiration with CDU guidance may be applicable in treating arterial dissection, especially when conservative treatments cannot be expected to improve severe flow disturbances.

Varicella-zoster virus (VZV) has been known to cause various eye disorders in both immunocompetent and immunocompromised patients. We present a case of a forty-nine-year-old female patient with acquired immunodeficiency syndrome (AIDS) who presented with headache, fever, and blurred vision. Cerebrospinal fluid (CSF) analysis was consistent with VZV meningitis. Magnetic resonance imaging (MRI) of the brain showed enhancement of the right optic nerve indicative of optic neuritis. She responded well to acyclovir and steroids and discharged on the same. Four weeks after discharge, she presented with sudden onset blindness in the left eye. A cerebral angiogram revealed left retinal artery occlusion and was treated with tissue plasminogen activator (tPA). Funduscopic examination showed patchy areas of necrosis in the periphery which were rapidly progressive, diagnostic of posterior outer retinal necrosis (PORN). She was started on ganciclovir and cidofovir and experienced significant improvement in her visual acuity.
