RESUMEN

BACKGROUND: Bradykinin-mediated angioedema (AE) is a complication associated with thrombolysis for acute ischemic stroke. Risk factors are unknown and management is discussed. OBJECTIVES: To clarify risk factors associated with bradykinin-mediated AE after thrombolysis for acute ischemic stroke. METHODS: In a case-control study conducted at a French reference centre for bradykinin angiœdema, patients with thrombolysis for acute ischemic stroke and a diagnosis of bradykinin-mediated angiœdema, were compared to controls treated with thrombolysis treatment without angiœdema. RESULTS: Fifty-three thrombolysis-related AE were matched to 106 control subjects. The sites of attacks following thrombolysis for ischemic stroke mainly included tongue (34/53, 64%) and lips (26/53, 49%). The upper airways were involved in 37 (70%) cases. Three patients required mechanical ventilation. Patients with bradykinin-mediated angiœdema were more frequently women [33 (62%) vs. 44 (42%); P = 0.01], had higher frequency of prior ischemic stroke [12 (23%) vs. 9 (8%); P = 0.01], hypertension [46 (87%) vs. 70 (66%); P = 0.005], were more frequently treated with angiotensin-converting enzyme inhibitor [37 (70%) vs. 28 (26%); P < 0.001] and were more frequently hospitalized in intensive care medicine [ICU; 11 (21%) vs. 5 (5%); P = 0.004]. In multivariate analysis, factors associated with thrombolysis-related AE were female sex [odds ratio (OR), 3.04; 95% confident interval (CI), 1.32-7.01; P = 0.009] and treatment with angiotensin-converting enzyme inhibitors [(OR), 6.08; 95% (CI), 2.17-17.07; P < 0.001]. CONCLUSIONS: This case-control study points out angiotensin-converting enzyme inhibitors and female sex as risk factors of bradykinin AE associated with thrombolysis for ischemic stroke.

RESUMEN

OBJECTIVES: To evaluate the prognostic value of cerebral border-zone infarctions (watershed infarctions) on the early postoperative outcomes of patients undergoing carotid endarterectomy (CEA) after acute ischemic stroke (AIS). METHODS: Sixty-six (66) patients with symptomatic carotid stenosis (SCS) that underwent ipsilateral CEA after AIS from January 2007 to March 2012 were included in this study. They were divided into two groups according to the topographic patterns of the stroke: group 1, Territorial Cerebral Ischemic Strokes (TCIS) caused by emboli of carotid origin; group 2, cerebral border-zone infarctions (CBZI) related to an SCS associated with hemodynamic impairment. All data was collected in a prospective database and analyzed. Outcome measures included postoperative neurological morbidity and 30-day mortality. RESULTS: Forty-three (43) patients (65.15%) experienced TCIS and were included in group 1, 23 patients (34.85%) had a CBZI and were included in group 2. There were no postoperative deaths. The postoperative neurologic morbidity rate was significantly higher in the CBZI group (22% vs. 2%, p = 0.02). Multivariate analysis demonstrates that CBZI was the only independent predictive factor of neurologic morbidity after CEA for AIS related to an SCS. Furthermore, the risk of postoperative neurologic morbidity remained significantly higher for patients with CBZI after adjustment for age, sex, initial NHISS scores, and associated contralateral carotid occlusion (HR: 0.059, 95% CI 0.004-0.85; p = 0.03). CONCLUSION: CBZIs, compared to TCIS, were associated with a higher neurological complication rate during the postoperative period after CEA for SCS in cases of AIS. Further studies are required to better define the timing and the best treatment modality for patients with CBZI related to an SCS in order to reduce associated procedural complications.

RESUMEN

INTRODUCTION: Various clinical manifestations can occur in syphilis, especially meningovascular syphilis. We report three cases of ischemic stroke related to meningovascular syphilis and HIV infection. CASE REPORTS: Three men, aged 30, 31 and 41, presented typical neurologic deficit leading to the diagnosis of ischemic stroke. Radiographic investigations showed internal carotid thrombosis in two patients, and a basilar stenosis in the third. CSF analysis and blood samples revealed meningovascular syphilis associated with HIV infection. The other explorations were normal. CONCLUSION: Due to the reemergence of syphilis, search for Treponema pallidum infection should be systematic in young stroke victims.

RESUMEN

INTRODUCTION: Intravenous thrombolysis with rt-Pa in stroke has been approved in France since 2002. We report an evaluation of our practice. We have tried to identify predictive factors of dependence and death, and to compare our results with the data of the literature. PATIENTS AND METHOD: All patients treated with intravenous rt-PA within the first 270min after the stroke onset were included. Univariate, then multivariate analyses were performed to determine the variables influencing the functional outcome at 3 months follow-up, according to a dichotomy established from the modified Rankin scale. RESULTS: One hundred and forty-two patients were included in this study (mean initial National Institute of Health Stroke Scale [NIHSS]: 15). Fifty percent had a Rankin score higher than 2 at 3 months follow-up. NIHSS above 12, glycemia of at least 120mg/l, and systolic blood pressure above 160mmHg at admission were identified as independent predictive factors of poor functional outcome. Less than 4 points decrease of NIHSS proved to be a simple and early predictor of poor functional outcome at 3 months follow-up. CONCLUSIONS: In terms of safety and efficacy the data issuing from the daily activity of our stroke unit are comparable with those of clinical trials.

RESUMEN

Wandering spleen is a rare condition which can be diagnosed with facility by conventional nuclear medicine imaging techniques. We present one case in which generalized lymphosarcoma involving a wandering spleen was proved by percutaneous aspiration biopsy. Evaluation of a liver-spleen scan in which the normal splenic image is not definitely seen should include extension of the scan field to include the lower abdomen, because of the possibility of ectopic splenic position.
