Summary
Noninvasive duplex ultrasound now allows accurate diagnosis of mesenteric arterial occlusive disease. This technology assesses splanchnic circulation, measuring blood flow changes after meals and with medications.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Gastroenterology
Background:
- Accurate diagnosis of mesenteric arterial occlusive disease historically relied on invasive arteriography.
- Noninvasive diagnostic methods for the splanchnic circulation were previously unavailable.
Purpose of the Study:
- To introduce and evaluate duplex ultrasound scanning as a noninvasive method for assessing mesenteric arterial occlusive disease.
- To demonstrate the utility of duplex ultrasound in evaluating splanchnic circulation.
Main Methods:
- Utilized recent innovations in duplex ultrasound scan technology.
- Applied duplex scanning to noninvasively assess the splanchnic circulation in humans.
- Measured postprandial changes in celiac and superior mesenteric arterial blood flow.
Main Results:
- Duplex ultrasound scanning provides a noninvasive method for assessing splanchnic circulation.
- Successfully measured changes in arterial blood flow after meals.
- Demonstrated ability to measure visceral flow changes induced by pharmacologic stimuli.
Conclusions:
- Duplex ultrasound scanning is a viable noninvasive tool for diagnosing mesenteric arterial occlusive disease.
- This technology enables accurate assessment of splanchnic hemodynamics.
- Offers a significant advancement over traditional invasive diagnostic methods.
