Objective To introduce the treatment and clinical result of reconstructing femoral artery with external jugular vein graft. Methods From June 2002 to April 2006, 22 cases of femoral artery defects caused by pseudoaneurysm resection, were reconstructed withexternal jugular vein graft by microsurgical technique. There were 20 males and2 females, aging 25-46 years (mean 31.2 years). The length of femoral artery defects was 5-9 cm, with an average of 6.8 cm. The location was left in 14 cases and right in 8 cases.Results Ten cases achieved healing by the first intention, and 4 cases by the second intention. The other 8 cases need the regional flap repair because the wound splited open and became ulcer. Femoral artery defects were reconstructed successfully and the pulse of dorsal arteries of foot could be felt except 1 case of bleeding of anastomotic rupture. Eighteen patients were followed up 1-30 months, and no pseudoaneurysm recurred. Color ultrasound Doppler detection showed that the external jugular veins took place of the femoral artery defects in 12 cases. Conclusion External jugular vein is stable at anatomy and easy-to-obtain. Its calibre is close to that of the femoral artery. It can be used for reconstructing femoral artery defects as the vein material. The operation is easy and the clinical result is sure.

Objective To discuss the definition of complicated giant cell tumor of the bone and retrospectively analyze the treatment protocols and their therapeutic results so as to provide a clinical basis for reducing the postoperative recurrence of this kind of tumor. Methods From April 2001 to April 2005, 22patients (11 males and 11 females, aged 15-66 years) with complicated giant cell tumor of the bone were treated by the marginal or wide excision. The tumor was located in the distal femur in 10 patients, the proximal tibia in 5, theproximal femur in 2, the proximal humerus in 2, the hip bone in 2, and the distal radius in 1. The Campanicci′s grading system was used and the patients were grouped as follows: Grade Ⅱ in 4 patients, and Grade Ⅲ in 18. The functional results of the patients were assessed by the clinical examination. The reconstruction methods were used in the forms of osteoarticular allografting (14 patients) and total arthroplasty (8 patients). Results The analysis on the follow-up (6-48 months, averaged 23 months) of the 22 patients revealedthat the complicated factors were as follows: the tumor breaking through the cortex with an extraosseous mass; the tumor having pathologic fracture; the tumor representing more biologically-aggressive lesions; and the tumor having one or more local recurrences. Two patients (9%) had a local recurrence respectively 8 and 11 months after operation, but improved respectively by limb amputation and radiotherapy. Total arthroplasty achieved a better articular function than osteoarticular allografting. All the patients with osteoarticular allografts showed various degrees of the bone union of the allograft with the host bone. Conclusion The marginal or wide excision of this kind of complicated giant cell tumor of the bone combined withosteoarticular allograft or total arthroplasty can reduce the local recurrence of the tumor and achieve a certain degree of the articular motion function.
Objective To discuss the surgical method and effect of repair of damage injury in the hands. Methods Of the 29 cases, 22 were males, 7 were females. Their ages ranged from 15 to 31.The size of defect areas ranged from 18 cm×8 cm to 22 cm×10 cm .Along with dorsalis pedis flap, lateral hemi-pulp flap was takenfrom great toe and first web space flap. The second toe was taken from one footto reconstruct the thumb, second and third toe from another foot was used to reconstruct two fingers. The dorsalis pedis flaps were used to cover palm and dorsum of hand. The lateral hemi-pulp flaps from great toe and first web space flapswere used to reconstruct first web space of hand.Results With the 58 combined flaps, 29 thumbs and 58 fingers were reconstructed. Followups was done for 1 to 8 years.All the thumbsand fingers of 29 hands were reconstructed. Their shape and function were well recovered. Conclusion This new surgical method is effective inpreserving the function of injured hand. The function of the injured hands can be preserved by this surgical method, therefore this method is optimal.
Objective To explore better approach of resecting tumoraround the anterior skull base and reconstructing the anterior skull base.Methods In November 2004, a 49-years-old male patient with intracranial recrudescent adenoid cystic carcinoma in the anterior cranial fossa was treated using modified transcranial approach. Neurosurgeon and rhinolaryngologist cooperated to excise the tumour completely, and to reconstruct anterior skull base using the pedicle periosteum temproal musculofascial flap(15 cm×10 cm) andthe pedicle flap of aponeurosis of occipitofron talis muscle and muscular fasciae(10 cm×6 cm).Results After operation, the wound healed by first intention. Complication, such as infection and cerebrospinal rhinorrhea, did not occur. The patient was discharged 10 days after operation, and was followed up for 8 months, no local recurrence were investigated and no scar formed over the face.Conclusion The modified transcranial approachis a relatively novel exposure that enables the skilled cranial base surgeon tosafely resect many malignant lesions previously and to reconstruct the defect of anterior skull base together.
Objective To evaluate the advantages and disadvantages of vascularized free peroneal composite flaps for reconstruction of oral and maxillofacial defects. Methods From November 1999 to December 2002, 28 cases of oral maxillofacial defects were reconstructed with vascularized free peroneal composite flaps, with fibulacutaneous flap in 21 cases and with fibulamyocutaneous flap in 7 cases. Three cases received insertion of dental implants into the fibula flap. The flap size was 3.0 cm×5.5 cm to 8.0 cm ×12.0 cm; the fibula length was 5.5 cm to 16.0 cm. Results Of the 28 flaps reconstructed, 24 survived,3 necrosed partially and 1 necrosed completely. All the 5 implants survived andachieved good bone integration in 3 cases. Twenty-six cases were followed up 1-36 months with an average of 18.5 months, the facial appearance and the vocal function were satisfactory in 23 cases. Conclusion Vascularized peroneal flap has many advantages and is one of the optimal flaps for reconstruction of oral maxillofacial defects.
