Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

75
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...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

252
Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...

Summary

High-flow priapism, an erection lasting over four hours due to abnormal penile blood flow, can be effectively treated with super-selective embolization. This minimally invasive procedure offers an 80% success rate with a low risk of erectile dysfunction.

Area of Science:

  • Urology
  • Vascular Surgery

Background:

  • Priapism is defined as an erection lasting four or more hours, unrelated to sexual stimulation.
  • It is categorized into low-flow, stuttering, and high-flow types, each with distinct etiologies and management strategies.

Observation:

  • A 24-year-old male presented with high-flow priapism.
  • High-flow priapism is characterized by an abnormal arteriovenous fistula within the penis.

Findings:

  • Super-selective embolization is the primary treatment for high-flow priapism when conservative measures are ineffective.
  • This interventional radiology technique demonstrated an 80% success rate in the presented case.

Implications:

  • Super-selective embolization offers a high success rate for treating high-flow priapism.
  • The procedure is associated with a low incidence of post-treatment erectile dysfunction, preserving sexual function.
