1.Study on anatomical basis of skin flaps based on the blood supply of the rectus abdominis muscle
Journal of Practical Medicine 2005;530(11):59-62
The investigation was performed in 20 cadavers (dissection in 17 formaldehyde preserved and dye injection in 3 fresh ones). The results of study showed that: average, each rectus abdominal muscle has 4.97 vessel with 0.5-0.6 mm in diameter arising from the anterior gone up through the sheath of abdominal muscle. Among them, 4.56 arising from the deep inferior epigastric artery (DIEA) and they concentrate mainly in the paraumbilical area (87.7%). The cutaneous blood supply (dye coloured area) of the DIEA was 19.5 x 14 cm in the supra and infra umbilical regions. The DIEA and the vein form a suitable pedicle for free tissue transfer. The design of different skin flaps patterns was proposed by results.

2 pestle flaps, 4 peripheral pedicular flap, 4 flaps of outside of limb and 2 flaps of inside of limb with central pedicle which were used as island fascio cutaneous flaps with the distal facio- fatty pedicles treated for 12 patients from different hospitals. Results have shown that all flaps lived; 2 flaps were healed in phase II; there were no necrosis or no cases which must be alternated by other method.

3.Contribution of the anterior interosseous artery to the blood supply for posterior forearm region and applications in designing the posterior interosseous forearm flap
Journal of Medical Research 2005;37(4):5-10
The anterior interosseous artery (AIA) plays an essential role in designing the posterior interosseous forearm flap (P.I.F.F). Understanding about anatomy of this artery permit us to find us to find out new solutions to design the P.I.F.F. in situations at which there are variations of the PIA. Objectives: (I) to evaluate the role of the anterior interosseous artery in the blood supplying to the posterior forearm region; (II) assessing the importance of anterior interosseous artery in designing the posterior interosseous forearm flap. Methods: 27 forearms of adults obove 25 years old, including 25 forearms fixed in formalin 4% and 2 fresh forearms, are objects for us to expose the AIA and PIA by different techniques. Results: There are 2-5 perforating branches of the AIA to the deep muscular layer of posterior. They connect to each other and to the muscular branch of the PIA, and their diameter becomes much larger in two cases of absence of the PIA. Branches from this series of arterial anastomoses distribute also to the skin of inferior half of posterior forearm. The posterior terminal branche of the AIA divides into the medial and recurrent branch. These two branches ascend and anastomose with the PIA and the muscular branch of the PIA, respectively. The medial branch of the posterior terminal branch is absent or disconnected with the PIA at two other cases. Conclusion: Our results indicate that the AiA supplies the inferior half and the deep muscular layer of the posterior forearm. The posterior interosseous forearm flap can still be raised in situations at which the posterior terminal branch of AIA communicates with the dorsal carpal arcus but not with the PIA and the PIA is absent.

4.The antherolateral thigh flap for reconstruction of head and neck defects
Journal of Vietnamese Medicine 2005;311(6):8-14
The antherolateral thigh flap (ALT flap) was first detected and used in 1984 by Song and colleagues. Long, reliable vascular pedicle, large skin area (15x34cm), did not influence area where flap removed, had not to change patient’s position during the operation. 31 patients with of head and neck defects The in Chang Gung Memorial Hospital was reconstructed by using 31 ALT flaps after malignant tumors removed: cheek cancer (15cases), throat cancer (3 cases). Clinical result: survival flap rate was 96.6%; only one flap was necrosis completely (3.4%). The ALT flap can be harvested safely and easily to reconstruct the complicated defects of head and neck with only minimal donor-site lesions

5.To compare the active vascularity restoration in microtome flaps after pediculation of arteries and vena
Journal of Practical Medicine 2003;425(5):46-49
66 flaps including 6 controlled, were divided into two models, each includes 30 flaps and each model was divided into 5 groups, evaluated after 4, 8, 12, 16 and 20 days after implantation. From the random implantation of a isolated pedicle of artery or vena in an abdomen skin flap, new blood vessels occurred and connected with the existent system of vessels in the flap. After 20 days, new vascularity was established in both models, as the same in the control group. Blood supply was considered appropriate and the flap could be moved safely along the newly implanted pedicle

6.Use of volatic kite flaps for covering the missing skin in thumb
Journal of Practical Medicine 2002;435(11):34-35
Six volatic kite flaps were used to covering the missing lesions of thumb skin. The flaps were collected from dorsum of phalanx 1 and from hand-finger join 2. The flaps involved three feeding components: the dorsal finger 2 artery that separated from radial artery, vein, the nerve branch that separated from radial nerve. These flaps were used effectively for covering the missing lesion of inter-phalangeal joint 1-2. It is more difficult in covering the palm of phalanx 2 of finger 1 because the flap must be collected from far area, the blood supply is poor in distal tip and the flap is stretched. (There was one case in which this flap was used to cover the palm of phalanx 2 of finger 1 had necrosis in distal part of the flap).

Comparision of tympanoplasty with temporal muscle fascia and pinna cartilage graft on 153 cases at ENT department -E hospital Hanoi. Temporal muscle fascia and pinna cartilage was used as material for tympanoplasty in 153 cases. The results show to be better especially for the large tympanique perforation

8.The experiences drawn from 139 cases of free flap transference for covering lower extremity defects
Journal of Practical Medicine 2004;480(5):16-19
138 patients (102 males, 36 females) aged 3-71 years old with 139 deficiencies of various causes in inferior limbs underwent a surgery of free flap transfer with 144 free flaps. Survived rate reached 134/144 flaps (93.05%), full necrosis in 10/144 flaps (6.95%). All cases were sucessfully operated exculding 5/10 cases of second time transfer. Near possible complications such as obstruction of the arterial connection of 4 flap-connect sites, obstruction of the venous connection of 6 flap sites, obstruction of venous-arterial connection of 2 sites, necrotic infection in 1 flap.
