RÉSUMÉ
INTRODUCTION: Cerebral venous sinus thrombosis (CVST) is an uncommon but fatal cause of stroke worldwide. Endovascular treatments could be life-saving in patients who don't treat with anticoagulants as a mainstay of treatment. Currently, there is no consensus considering the safety, efficacy, and also selected approaches of endovascular intervention for these patients. This systematic review evaluates the literature on endovascular thrombolysis (EVT) in CVST patients. MATERIALS AND METHODS: A comprehensive search was conducted through PubMed and Scopus databases between 2010 and 2021, with additional sources identified through cross-referencing. The primary outcomes were the safety and efficacy of EVT in CVST, including catheter-related and non-catheter-related complications, clinical outcomes, and radiological outcomes. RESULTS: A total of 10 studies comprising 339 patients were included. Most of the patients presented with headaches (86.72%) and/or focal neurologic deficits (45.43%) (modified Rankin Scale of 5 in 55.88%). Acquired coagulopathy and/or consuming estrogen/progesterone medication were the most frequent predisposing factors (45.59%). At presentation, 68.84% had multi-sinus involvement, and 28.90% had venous infarcts and/or intracranial hemorrhage (ICH). The overall complication rate was 10.3%, with a 2.94%, 1.47%, and 1.17% rate of ICH, herniation, and intracranial edema, respectively. The complete and partial postoperative radiographic resolution was reported in 89.97% of patients, increasing to 95.21% during the follow-up. Additionally, 72.22% of patients had no or mild neurologic deficit at discharge, rising to 91.18% at the last follow-up. The overall mortality rate was 7.07%. CONCLUSIONS: EVT can be an effective and safe treatment option for patients with refractory CVST or contraindications to systemic anticoagulation.
RÉSUMÉ
The objective of this study was to analyze the outcome of percutaneous nephrolithotomy (PCNL), laparoscopic and open anatrophic nephrolithotomy (AN) for management of patients with large staghorn renal stones. We analyzed the peri-operative parameters, overall treatment costs and changes in the function of the affected kidney on technetium-99 dimercaptosuccinic acid renal scintigraphy, done before the operation and before the final follow-up visit, in 45 adults who underwent PCNL (n = 16) versus laparoscopic (n = 15) versus open (n = 14) AN for large staghorn renal stones. All three groups had statistically similar preoperative characteristics, including the function of the operated kidney on renal scan. On the discharge day, the PCNL group had the lowest stone-free rate (43.75 %) compared to the laparoscopic (80 %) and open AN groups (92.85 %) (P = 0.009). After a mean follow-up period of 12.1 months, the decrease in the function of the operated kidney was greatest in the open AN group (-8.66 ± 4.97) compared to the laparoscopic AN (-6.04 ± 6.52) and PCNL group (-2.12 ± 2.77) (P = 0.003). The need for ancillary procedures to manage residual stones was greatest in the PCNL group and lowest in the open AN group. A similar trend was seen in overall treatment costs (P < 0.001). For management of large staghorn renal stones, the more invasive the procedure, the higher the one-session stone-free rate and the lower the need for ancillary procedures; however, greater renal functional loss can be anticipated. The need for ancillary procedures is a major determining factor in the overall cost of treatment, which was highest in the PCNL group.
