Summary
High-frequency ultrasound accurately maps dorsal hand arteries, aiding in surgical planning for local flaps. This study confirms the utility of Doppler ultrasound in visualizing these critical vascular structures for reconstructive procedures.
Area of Science:
- Vascular anatomy
- Medical imaging
- Hand surgery
Background:
- Dorsal hand arterial anatomy exhibits significant variability.
- Accurate preoperative mapping of these vessels is crucial for successful surgical interventions, particularly those involving local flaps.
Purpose of the Study:
- To define the role of high-frequency pulsed wave Doppler ultrasound in mapping the dorsal arterial anatomy of the hand.
- To correlate ultrasound findings with established anatomical data and intraoperative observations.
Main Methods:
- High-frequency pulsed wave Doppler ultrasound was employed to map the dorsal arterial anatomy in 50 normal hands.
- Eight clinical cases were assessed preoperatively, with seven undergoing surgery utilizing local flaps.
- Intraoperative confirmation of mapped vessels was performed.
Main Results:
- The study successfully mapped the dorsal arterial anatomy, revealing variations consistent with previous anatomical literature.
- Doppler ultrasound findings correlated well with anatomical studies.
- Intraoperative confirmation validated the accuracy of the preoperative ultrasound mapping in all surgical cases.
Conclusions:
- High-frequency pulsed wave Doppler ultrasound is a reliable and effective tool for mapping dorsal hand arterial anatomy.
- This imaging modality plays a defined role in the preoperative assessment and surgical planning for dorsal hand flaps.
- The findings support the integration of Doppler ultrasound in routine practice for hand surgery.
