Acute pulmonary embolism with inferior vena caval thrombus following radiofrequency ablation of the great saphenous vein despite early ultrasound surveillance.

The reported incidence of pulmonary embolism in the published literature after radiofrequency ablation of the great saphenous vein is exceedingly rare. Recent societal clinical practice guidelines recommend against routine postprocedural ultrasound screening for ablation-related thrombus extension in asymptomatic average-risk patients. However, screening is recommended for asymptomatic high-risk patients.

Unique presentation of renovascular hypertension due to fibromuscular dysplasia.

A 21-year-old female with a history of right nephrectomy due to trauma presented with several years of multidrug-resistant hypertension. Her workup included negative findings from autoimmune and vasculitides panels and urine catecholamine testing. Computed tomography showed an acute hairpin turn of her left renal artery.

Y-Chromosome Gene, , Protects Against Pulmonary Hypertension by Reducing Proinflammatory Chemokines.

Idiopathic pulmonary arterial hypertension (PAH) is a terminal pulmonary vascular disease characterized by increased pressure, right ventricular failure, and death. PAH exhibits a striking sex bias and is up to four times more prevalent in females. Understanding the molecular basis behind sex differences could help uncover novel therapies.
