Surgery, Gynecology & Obstetrics

|April 1, 1984

Summary

This summary is machine-generated.

A novel system detects a pulse beyond embolectomy sites to confirm arterial patency and distal vessel integrity before final surgical steps. This method ensures successful blood flow and vessel health.

Area of Science:

Vascular surgery
Medical device technology
Diagnostic tools

Background:

Assessing arterial patency after embolectomy or anastomosis is crucial for surgical success.
Current methods may require invasive procedures or delayed assessment.

Purpose of the Study:

To describe a new system for real-time assessment of arterial patency.
To evaluate the system's ability to test distal vessel condition post-intervention.

Main Methods:

Development of a system to generate a detectable pulse signal.
Utilizing a Doppler probe to detect the generated pulse distal to the surgical site.
Application of the system before completing proximal anastomosis or final angiography.

Main Results:

Related Experiment Videos

The system successfully produced a detectable pulse beyond the intervention site.
Doppler probe detection confirmed the presence of a pulse, indicating patency.
The method allowed for assessment of distal vessels prior to definitive surgical closure.

Conclusions:

The described system offers a non-invasive, immediate method for verifying arterial patency.
This technique aids in ensuring the success of embolectomy and anastomosis procedures.
It provides critical information for procedural completion and reduces the need for immediate confirmatory angiography.
