Hemodynamic Assessment of Arterial Perfusion by Using the Ultrasonographic Hand Acceleration Time: Protocol for a...

Area of Science:

• Vascular Medicine
• Diagnostic Ultrasound
• Ischemia Research

Background:

• Noninvasive methods for assessing hand perfusion lack standardization for diagnosing chronic upper limb ischemia.
• Ultrasonographic hand acceleration time (HAT) is a potential diagnostic tool requiring characterization and validation.

Purpose of the Study:

• To describe and quantify the hand acceleration time (HAT) technique for assessing hand perfusion.
• To evaluate HAT in patients with chronic upper limb ischemia and healthy volunteers.

Main Methods:

• Prospective, cross-sectional study using vascular duplex ultrasound (DUS) to measure HAT in 4 hand arteries.
• Included 15 patients with chronic upper limb ischemia and 15 healthy volunteers.
• Standard descriptive analysis and Mann-Whitney U test were employed.

Main Results:

• 30 participants (15 patients, 15 controls) were enrolled, with 15 ischemic and 30 nonischemic hands evaluated.
• Data analysis and publication timeline detailed, with results available prior to protocol submission.
• No further analyses are planned beyond the published study.

Conclusions:

• This study systematically evaluated vascular DUS-measured HAT as a novel diagnostic tool for chronic upper limb ischemia.
• Preliminary cutoff values were established to aid clinical decision-making.
• HAT shows potential as a quick, noninvasive diagnostic tool, complementing existing methods.
