three failed cases were found in patients with hyperfibrinogenemia and needed further reconstruction with another flap. The overall success rate was 88.5% (23/26). Hematologic disorder is not a predicted factor of free flap failure. The key factors for success flap survival in patients with hematologic disorders include Selleck JAK inhibitor preoperative knowledge of the medical condition and monitoring potential post-operative complications, aggressive hematologist consultations, and meticulous non-traumatic surgical anastomosis. © 2014 Wiley Periodicals, Inc.

“The acellular nerve graft that can provide internal structure and extracellular matrix components of the nerve is an alternative for repair of peripheral nerve defects. However, results of the acellular nerve grafting for nerve repair still remain inconsistent. This study aimed to investigate if supplementing bone marrow mesenchymal stromal cells (MSCs) could improve the results of nerve repair with the acellular nerve graft in a 10-mm sciatic nerve defect model in mice. Eighteen mice were divided into three groups (n = 6 for each group) for nerve repairs with the nerve autograft, the acellular nerve
graft, and the acellular nerve graft by supplemented with MSCs (5 × 105) fibrin glue around the graft. The mouse static sciatic RAD001 index was evaluated by walking-track testing every 2 weeks. The weight preservation of the triceps surae muscles and histomorphometric assessment of triceps surae muscles and repaired nerves were examined at week 8. The results showed that the nerve Non-specific serine/threonine protein kinase repair by the nerve autografting obtained the best functional recovery of limb. The nerve repair with the acellular nerve graft supplemented with MSCs achieved better functional
recovery and higher axon number than that with the acellular nerve graft alone at week 8 postoperatively. The results indicated that supplementing MSCs might help to improve nerve regeneration and functional recovery in repair of the nerve defect with the acellular nerve graft. © 2011 Wiley-Liss, Inc.

“This study aims to compare the major anatomical aspects among anterolateral thigh, parascapular and lateral arm flaps. Sixty flaps were dissected in 20 human cadavers, comparing their vascular pedicle length, flap thickness and arterial/venous pedicle diameters. The vascular pedicle length (from the origin of the vascular pedicle to its entry into the skin flap) of anterolateral thigh flap (13.43 ± 3.92 cm, lateral circumflex femoral artery) was longer than parascapular (9.07 ± 1.20 cm, circumflex scapular artery) and lateral arm flap (8.90 ± 1.65 cm, posterior collateral radial artery) (P < 0.001). The thickness of lateral arm flap (6.32 ± 2.33 mm) was lesser than parascapular (8.59 ± 2.93 mm) and anterolateral thigh flap (9.30 ± 3.54 mm) (P < 0.001). The arterial/venous pedicle diameters of lateral arm flap (2.
