Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

35
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: Prostacyclin Receptor Agonists

247
Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...

Area of Science:

  • Urology
  • Interventional Radiology
  • Vascular Surgery

Background:

  • High-flow priapism is a rare condition with limited treatment consensus, especially in Australia.
  • Existing literature on management strategies is scarce.
  • This study addresses the need for data on effective treatments for high-flow priapism.

Purpose of the Study:

  • To present the institutional network's decade-long experience managing high-flow priapism.
  • To evaluate the efficacy and safety of super-selective gelatin sponge (Gelfoam) embolisation of the internal pudendal artery.
  • To compare findings with existing literature.

Main Methods:

  • Retrospective review of patient records within a multicentre institutional network over 10 years.
  • In-depth analysis of high-flow priapism cases treated with embolisation.
  • Comparison of institutional data with current literature.

Main Results:

  • Out of 93 priapism cases, 4% (four patients) had high-flow priapism.
  • Two patients with high-flow priapism were treated with super-selective Gelfoam embolisation of the internal pudendal artery.
  • Both patients experienced rapid detumescence and returned to baseline erectile function with no recurrence or post-treatment erectile dysfunction.

Conclusions:

  • Super-selective embolisation of the internal pudendal artery is a recommended treatment for high-flow priapism.
  • Gelfoam is an effective temporary embolic agent for this procedure.
  • The technique demonstrated safety and efficacy, facilitating a quick and sustained return to baseline erectile function.
