Intravasation during hysterosalpingography using oil-base contrast media

Area of Science:

• Radiology
• Gynecologic Imaging
• Contrast Media Applications

Background:

• Oil-based contrast media are used for hysterosalpingography, offering detailed imaging.
• Intravasation and embolization of oily media are potential complications, particularly with high-viscosity agents like Lipiodol.

Purpose of the Study:

• To evaluate the safety and morbidity associated with Ethiodol, a low-viscosity oil contrast medium, during hysterosalpingography.
• To assess the incidence and consequences of intravasation and embolization with Ethiodol.

Main Methods:

• Retrospective review of 13 cases undergoing hysterosalpingography with Ethiodol.
• Utilized fluoroscopy to detect early signs of intravasation and manage contrast volume.
• Documented clinical histories and outcomes, including instances of embolization.

Main Results:

• 13 cases of intravasation were identified, with 6 involving embolization.
• No significant morbidity was observed in any of the cases.
• Embolization of low-viscosity oil contrast media in low volumes was found to be a relatively benign event.

Conclusions:

• Hysterosalpingography with low-viscosity Ethiodol, when performed with appropriate technique, is associated with minimal risk of morbidity.
• Proper timing and avoidance of excessive pressure can reduce the incidence of intravasation.
• Low-volume embolization of Ethiodol appears to be a safe occurrence in hysterosalpingography.
