“In this article,we revisited the anatomy of the distal perforator of the descending genicular artery (DGA) and report the clinical application of its perforator propeller flap in the reconstruction of soft tissue defects around the knee. Forty fresh human

lower limbs were dissected to redefine the anatomy of the branches of the DGA and their perforators and the anatomical landmarks for clinical applications. Five patients underwent “propeller” distal anteromedial thigh (AMT) flaps based on DGA perforators for the reconstruction of post-traumatic (n = 4) Enzalutamide and post-oncologic (n = 1) soft tissue defects occurring near the knee with a size ranging from 4.8 cm × 6.2 cm to 10.5 cm × 18.2 cm. A constant cutaneous perforator of the osteoarticular branch (OAB) of the learn more DGA was found in the distal AMT fossa with a mean caliber of 1.2 ± 0.4 mm. It arose 9.4 ± 3.1 cm distally to the origin of the OAB and 4.0 ± 0.4 cm above the knee joint. The size of the harvested flaps ranged from 6.0 cm × 7.1 cm to 11.0 cm × 20.1 cm. All the flaps healed uneventfully at a mean period of 7.4 months. All the patients regained full range motion of the knee-joint. Our study provided evidence of the vascular supply and the clinical application of the distal AMT flap based on a constant

perforator arising from the OAB of the DGA. This flap may be a versatile alternative for the reconstruction of the defects around the knee because of its consistent vascular pedicle, pliability and thinness, adequate retrograde perfusion, and the possible direct suture of the donor site. © 2014 Wiley Periodicals, Inc.

“Background: Three-dimensional computed tomographic angiography (3D CTA) can be used preoperatively to evaluate the course and caliber of perforating blood vessels for abdominal free-flap breast reconstruction. For postmastectomy breast reconstruction, many women inquire whether the abdominal tissue volume will match that of the breast to be removed. Therefore, our

goal was to estimate preoperative volume and weight of the proposed flap and compare them with the actual volume and weight to determine if diagnostic imaging can accurately identify the amount isometheptene of tissue that could potentially to be harvested. Methods: Preoperative 3D CTA was performed in 15 patients, who underwent breast reconstruction using the deep inferior epigastric artery perforator flap. Before each angiogram, stereotactic fiducials were placed on the planned flap outline. The radiologist reviewed each preoperative angiogram to estimate the volume, and thus, weight of the flap. These estimated weights were compared with the actual intraoperative weights. Results: The average estimated weight was 99.7% of the actual weight.
