Summary
High-flow priapism, often caused by trauma, involves uncontrolled arterial inflow. Superselective arterial embolization successfully treated a case of high-flow priapism resulting from Foley catheter trauma.
Area of Science:
- Urology
- Vascular Surgery
- Emergency Medicine
Background:
- Priapism is a prolonged, painful erection unrelated to sexual stimulation.
- Veno-occlusive priapism results from venous outflow obstruction.
- High-flow priapism stems from arterial inflow issues, often due to trauma.
Observation:
- A patient presented with high-flow priapism secondary to urethral trauma from a misplaced Foley catheter.
- This specific trauma led to bilateral arteriocavernosal fistulae.
Findings:
- Superselective arterial embolization of the internal pudendal arteries was performed using metallic microcoils.
- The procedure successfully resolved the priapism, leading to penile detumescence without complications.
Implications:
- This case demonstrates the efficacy of superselective arterial embolization for treating high-flow priapism.
- It highlights a rare cause of high-flow priapism and its successful management.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
01:29Venous Thrombosis III: Interprofessional Care
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
01:25Urinary Tract Calculi VI: Surgical Management
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.

01:30Anticoagulant Drugs: Low-Molecular-Weight Heparins
Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
