Background Bridging treatment with intravenous thrombolysis (IVT) before endovascular thrombectomy (EVT) in acute ischemic stroke is applied under the assumption of benefits for patients with large vessel occlusion (LVO). However, the benefit of this additional step has not yet been proven. Purpose To compare procedural parameters (procedural time, number of attempts), complications, and clinical outcome in patients receiving EVT vs. patients with bridging treatment. Material and Methods In this prospective study all patients had acute anterior cerebral circulation occlusion and were treated with EVT. All patients were selected for treatment based on clinical criteria, multimodal computed tomography (CT) imaging. Eighty-four patients were treated with bridging IVT followed by EVT; 62 patients were treated with EVT only. Results Bridging therapy did not influence endovascular procedure time ( P = 0.71) or number of attempts needed ( P = 0.63). Bleeding from any site was more common in the bridging group (27, 32%) vs. the EVT group (12, 19%) ( P = 0.09). Functional independence modified Rankin Scale after 90 days was slightly higher in the bridging group (44%) vs. the EVT group (42%) ( P = 0.14). Mortality did not differ significantly at 90 days: 17% in the bridging group vs. 21% in EVT alone ( P = 0.57). Both treatment methods showed high recanalization rates: 94% in the bridging group and 89% for EVT alone. Conclusion Bridging treatment in LVO did not show benefits or elevated risks of complications in comparison to EVT only. The bridging group did not show significantly better neurological outcome or significant impact on procedural parameters vs. EVT alone.

Patient: Male, 49-year-old Final Diagnosis: Neurosyphilis Symptoms: Behavioral disturbance • confusion • disorientation • hallucinations • memory loss Medication: Penicillin G • acyclovir Clinical Procedure: Lumbar puncture Specialty: Infectious Diseases • Neurology • Radiology Objective: Rare disease Background: Neurosyphilis is a central nervous system infection caused by Treponema pallidum , that can develop at any time after the initial infection. The clinical signs of neurosyphilis are very variable, as well as its radiological features, and it is a diagnostic challenge. Knowledge of clinical symptoms and correct laboratory diagnostics, combined with routine radiological examination and additional diagnostic tools, such as high-resolution, three-dimensional FLAIR sequence, T2-weighted, and T1-weighted contrast-enhanced magnetic resonance imaging (MRI) are key to making an accurate diagnosis of neurosyphilis. Case Report: We present the clinical case of a patient who presented a 1-year history of vague clinical symptoms and was misdiagnosed with herpes simplex virus (HSV) encephalitis. Initial head MRI revealed extensive cerebral white matter lesions with cortical contrast enhancement, mainly of anterior and medial parts of the left temporal lobe, as typically seen in HSV encephalitis. Empirical therapy with acyclovir was started until a diagnosis of syphilis was confirmed with laboratory findings. Later, the therapy was changed to penicillin G. The patient’s condition improved after receiving targeted treatment. A control MRI scan was performed, and previously detected changes in the brain had decreased significantly. Conclusions: MRI is the imaging of choice to support the diagnosis of neurosyphilis. Our findings suggest that neuroimaging can play an important role in indicating suspicion of syphilitic encephalitis. Enhancement of the anterior and medial parts of the temporal lobe is an atypical imaging finding, and it can simulate an infection with HSV. Early treatment is critical to a positive outcome.

Communicated by Pçteris StradiòðMechanical thrombectomy as an active treatment method has recently been chosen for patients with large artery occlusions and thrombolysis beyond a time window. The aim of our study was to evaluate the results of endovascular treatment in patients with proximal vessel occlusion, compare this group with the intravenous thrombolysis group, and to identify possible criteria of active treatment. The prospective study included 81 patients hospitalised in the Pauls Stradiòð Clinical University Hospital due to acute ischemic stroke; 48 of them received mechanical thrombectomy and 33 -intravenous thrombolysis. Thrombectomy (TE) was performed using Solitaire FR stent retrievers. The NIHSS score was used for evaluation of early therapy results and mRS (modified Rankin Scale) was used for late therapy results. ASPECTS was used to define the lesion size using imaging on admission and after treatment. Median NIHSS on admission was higher in the TE group -16 (range 12 to 19) than in the TL group -12 (range 8 to 15) (p < 0.05). Ninety days after treatment, mRS (0-2) was seen in 67% of patients in the TE group (n = 29), and 34% of patients in the TL group (n = 9) patients (p < 0.05). Median ASPECTS was lower in TE group -5, in comparison to the TL group -7 (p < 0.01) Mortality frequency was higher in the TL group (p > 0.05). Frequency of symptomatic intracerebral haemorrhages was similar in the groups. Mechanical thrombectomy can achieve better late functional outcome than thrombolysis in a selected patients group.
