The distally based ulnar artery forearm flap supplied by the dorsal carpal arch.

It is accepted that the ulnar artery forearm flap is dependent on the integrity of the palmar arches for ulnar arterial backflow and the patency of both radial and ulnar arteries. A patient is presented who demonstrates the successful use of the ulnar artery forearm flap supplied by the dorsal carpal arch via the dorsal branch of the ulnar artery. In this patient, the ulnar artery was damaged distal to the dorsal branch of the ulnar artery. A distally based ulnar forearm was dissected up to the dorsal branch of the ulnar artery and pivoted around this branch. This flap survived completely with no postoperative problem.

U-I flap.

This article describes the principle, vascular basis, and applications of a new flap derived from the dorsal hand skin. The principle is a pedicle-lengthening procedure that is to revert a "U"-shaped vascular structure into an "I"-shaped vascular structure. By using this principle, a dorsal metacarpal flap, comprising the second dorsal metacarpal artery, the dorsal carpal arch, the dorsal branch of the radial artery, and the first dorsal metacarpal artery, was developed. In this flap, the skin territory was placed over the first dorsal metacarpal artery. The flap was rotated around a web space-connecting vessel between the second dorsal metacarpal artery and the palmar arterial system. We used this flap for resurfacing large defects beyond the proximal interphalangeal joint and degloved fingers in six cases. In two cases, the flap was used as an innervated flap. In one case, the flap was used as a tenocutaneous flap with a segment of the extensor indicis proprius tendon. We found this flap to be useful in selected circumstances.

A new approach to the reverse dorsal metacarpal artery flap.

The distally based dorsal hand flap on the recurrent cutaneous branch was dissected as a reverse flap based on the connection between the dorsal branch of the proper digital artery and the terminal branches of the dorsal metacarpal artery at the level of the proximal phalanx. The reverse dorsal metacarpal artery flap dissected by this new approach was applied in five cases for coverage of some areas in the fingers. Two flaps were raised on the second and three on the third intermetacarpal space. All flaps survived completely. The donor areas were closed by direct approximation.

The second dorsal metacarpal artery flap with double pivot points.

A flap with double pivot points based on the second dorsal metacarpal artery was used in 13 cases with no complete failures. In 2 cases, the branches of the radial nerve were included in the flap. In 1 case, the flap was used as a tenocutaneous flap with a segment of the extensor indicis proprius tendon. To obtain a flap with double pivot points, the dissection of the vascular pedicle of a distally based second dorsal metacarpal flap is continued proximally under the second dorsal metacarpal artery up to its origin. In this flap the main pivot point coincides with the origin of the SDMA and the second pivot point with the entry point of the recurrent cutaneous branch into the flap. We found this flap to be very versatile, reliable, and quite easy and quick to raise. We report our experience with this flap as a very useful addition to reconstructive procedures, especially for thumb defects.

Free arterialized venous flap for the reconstruction of defects of the hand: new modifications.

Arterialized venous flaps were used in 13 cases for reconstruction of defects in the hand. The flap was used as a fascial venous flap in three cases, and as a sensory venous flap in three cases. In three cases, the flap was designed as an ipsilateral pedicled flap, similar to a standard free flap, instead of as a contralateral pedicled type. Ten flaps survived completely. Two flaps underwent superficial necrosis, with viable subcutaneous-tissue layers.

Liposuction of the kneecap area under tourniquet: a superdry procedure.

In this paper, we report our experience and describe the technique of liposuction under tourniquet. This technique facilitates liposuction in the kneecap area and makes it bloodless. The approach described is effective and necessitates a relatively brief intraoperative and postoperative period, with inherently less morbidity. We obtained satisfactory results using this simple procedure.
