Bilateral Renal Artery Thromboembolism During Thrombolytic Therapy for Embolism-Induced Acute Limb Ischemia.

We report a case of bilateral renal infarction following thrombolytic and anticoagulant therapy for left ventricular embolism-induced lower leg artery ischemia. Imaging demonstrated thrombi from the left ventricle leading to bilateral renal arterial occlusion. Catheter embolectomy and long-term oral anticoagulant therapy were initiated, and the patient recovered with no residual complications. (Level of Difficulty: Intermediate.).

The diversities in thyroid cytopathology practices among Asian countries using the Bethesda system for reporting thyroid cytopathology.

BACKGROUND: The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) has been adopted and widely used among Asian countries. This study aims to investigate the application of TBSRTC in thyroid cytology practice among Asian countries. METHODS: We searched electronic databases including PubMed and Web of Science from 2010 to 2019. Meta-analysis of proportion and their 95% confidence intervals (CIs) were calculated using the random-effect model. Meta-regression and subgroup analysis were used to search for heterogeneity origins. RESULTS: We included 42 Asian studies with 84.953 fine-needle aspirations. Among six categories, benign was the most commonly diagnosed category. The resection rate (RR) and risk of malignancy (ROM) were highest in malignant and SM categories, and lowest among benign nodules. Thyroid cytology practice in Asia was characterized by a low RR and high ROM in patients with indeterminate thyroid nodules. There was a significant amount of heterogeneities of TBSRTC outputs (frequency, resection rate, and malignancy risk) among Asian countries. Meta-regression showed that the sources of heterogeneity might stem from the differences in study origin and the application of molecular testing. We highlighted the usefulness of preoperative molecular testing to select patients for surgery. CONCLUSIONS: Our study provided insight regarding thyroid cytology practice among Asian countries. Active surveillance is commonly used in Asian practice resulting in a low RR and high ROM for indeterminate nodules. There are still variations in general thyroid cytology practice in Asia. Future guidelines and consensus regarding the application of TBSRTC in thyroid cytology practice among Asian countries are required.
