[Microvascular study of the transmidline scapular flap vascularized by the contralateral circumflex scapular artery].

OBJECTIVE

To observe the microvascular distribution of the transmidline scapular flap supplied by the contralateral circumflex scapular artery.

METHODS

The integument and deep tissues of 6 fresh cadavers were dissected and radiographed after vermilion mixture was injected to the unilateral circumflex scapular artery.

RESULTS

The vascular tree passed the midline and reached to the contralateral acromion. The vessel density was the highest in the irrigating side of the back, which was higher in the middle area. In the contralateral side,the high vessel density concentrated in the upper part of the back.

CONCLUSIONS

The result revealed the direct evidence for the clinical application of the transmidline scapular flap. In design and elevating of the transmidline scapular flap, it should be slanting to the upper part of the contralateral back.
