Objective: To explore the clinical effects of free superficial peroneal artery perforator flaps in repairing skin and soft tissue defects of the hallux. Methods: A retrospective observational study was conducted. From January 2020 to January 2021, 13 patients with skin and soft tissue defects of the hallux who met the inclusion criteria were admitted to Department of Foot and Ankle Surgery of Ruihua Affiliated Hospital of Soochow University, including 12 males and 1 female, aged 26 to 53 years. Before operation, the perforating point of the superficial peroneal artery perforator was located by color Doppler ultrasound on the calf on the same side of the affected hallux and marked on the body surface. The operation was performed under spinal anesthesia combined with continuous epidural anesthesia. The area of skin and soft tissue defect after debridement was 4.5 cm×2.5 cm to 12.0 cm×3.0 cm. According to the size and shape of the wound, the superficial peroneal artery perforator flap was designed with the line between the fibular head and the lateral malleolus tip parallel shifting 2 cm to the tibial side as the flap axis line, and the perforating point of the perforator near the midpoint of the axis line as the center. The cut area of the flap was 5.0 cm×3.0 cm to 13.0 cm×4.0 cm, and part of the deep fascia was cut when the pedicle was freed. The donor site wound was sutured directly. During the operation, the number and type of the perforator and the cutting time of the flap were recorded, and the length of the perforator pedicle and diameter of the perforator were measured. The survival of the flap, the healing time and the healing condition of the donor and recipient areas were recorded after operation. The color, texture, elasticity of the flap, standing and walking functions of patients, the recovery of the donor area, and the patients' satisfaction with the recovery of the donor and recipient areas were recorded during the follow-up. At the last follow-up, the sensation of the flap was evaluated by the British Medical Association sensory function evaluation standard, the function of the affected limb was evaluated by the American Society of Foot and Ankle Surgery scoring system, and the excellent and good rate of the function of the affected limb was calculated. Results: A total of 13 perforators of the superficial peroneal artery were detected during the operation, all of which were septocutaneous perforators, and the perforator diameter was 0.3 to 0.5 mm. The vascular pedicle length was 2 to 5 cm. Flap cutting time was 11 to 26 minutes. The flaps of 13 patients all survived completely. The wounds at the donor and recipient sites healed well 9 to 18 days after operation. During follow-up of 6 to 14 months, the flaps had good color, texture, and elasticity; 11 patients had no obvious bloated appearance, and the other 2 patients underwent flap thinning and plastic surgery in the second stage because of their bloated appearance; all the patients returned to normal walking and standing functions. There was only one linear scar left in the donor site, with no obvious scar hyperplasia or hyperpigmentation. All the patients were satisfied with the recovery of the donor and recipient areas. At the last follow-up, the sensation of the flap was evaluated as grade S₃ in 2 cases, grade S₂ in 9 cases, and grade S₁ in 2 cases; the function of the affected limb was evaluated as excellent in 7 cases and good in 6 cases, with an excellent and good rate of 100%. Conclusions: The free superficial peroneal artery perforator flap has relatively constant vascular anatomy, which is thin and wear-resistant, with less damage to the donor site after flap excision, and can preserve the shape and function of the hallux to the greatest extent. It is an effective method for repairing skin and soft tissue defect of the hallux.

Objective: To compare the clinical application results of the FPTF (free posterior tibial artery perforator flap) and RFFF (radial forearm free flap) for reconstruction of head and neck defects. Methods: A retrospective analysis of 27 cases treated with FPTF (19 males and 8 females, aged 14-69 years) and 24 cases with RFFF (11 males and 13 females, aged 22-69 years) for head and neck defect reconstruction at Beijing Tongren Hospital of Capital Medical University from January 2015 to December 2020 was conducted. Flap size, vascular pedicle length, matching degree of recipient area blood vessels, preparation time, total operation time, hospital stay, recipient area complications, donor area complications and scale-based patient satisfaction were compared between two groups of patients with FTPF and RFFF. SPSS 26.0 statistical software was used for statistical analysis. Results: There was no statistically significant difference between the two groups of patients in tumor T staging (P=0.38), primary sites (P=0.05) and mean flap areas ((53.67±29.84) cm² vs. (41.13±11.08) cm², t=-1.472, P=0.14). However the mean vascular pedicle length of FPTF was more than that of RFFF ((11.15±2.48)cm vs. (8.50±1.69)cm, t=-4.071, P<0.01). The donor sites of 4 patients in FPTF group could be sutured directly, while all the 24 patients in RFFF group received skin grafts from the donor sites. There was no statistically significant difference in the recipient area arteries between two groups of flaps (P=0.10), with more commonly using of the facial artery (RFFF: FPTF=21∶27), but there was significant difference in the recipient area veins (P<0.01), with more commonly using of the external jugular vein in RFFF (14/24) than FPTF (4/32) and the posterior facial vein in FPTF (27/32) than RFFF (9/24). There were 10 recipient complications and 3 donor complications in RFFF group; no recipient complication and 3 donor complications occurred in FPTF group. With patient's subjective evaluation of the donor site at 12 months after surgery, FPTF was better than RFFF (χ²=22.241, P<0.01). Conclusions: FPTF is an alternative to RFFF in head and neck reconstruction and has unique advantages in aesthetics and clinical application.

The dorsalis pedis artery (DPA) was renamed from the anterior tibialis artery after it passed under the extensor retinaculum, and DPA travels between the extensor hallucis longus and extensor digitorum longus muscle along the dorsum of the foot. After giving off the proximal and distal tarsal, arcuate and medial tarsal branches, DPA enters the proximal first intermetatarsal space via the first dorsal metatarsal artery (FDMA), which courses over the first dorsal interosseous muscle (FDIM). For detailed knowledge of the neurovascular anatomy of a dorsalis pedis artery flap (DPAF) as a routine reconstructive procedure after the resection of oral malignant tumors, the precise neurovascular anatomy of DPAF must be studied along the DPA courses as above. In this first review article in the Korean language, the anatomical basis of DPAF is summarized and discussed after a delicate investigation of more than 35 recent articles and atlas textbooks. Many advantages of DPAF, such as a consistent flap vascular anatomy, acceptable donor site morbidity, and the ability to perform simultaneous flap harvest using oral cancer ablation procedures, and additional important risks with the pitfalls of DPAF were emphasized. This article will be helpful, particularly for young doctors during the special curriculum periods for the Korean National Board of Specialists in the field of oral and maxillofacial surgery, plastic surgery, otolaryngology, orthopedic surgery, etc.

OBJECTIVETo discuss the application of medial planta island flaps pedicled with anterior tibial artery perforator in front of inner malleolus for repairing small wounds around ankle.

METHODSFrom Jan. 2005 to Jun. 2009, 10 cases with small wounds around ankle were treated with medial planta island flaps pedicled with anterior tibial artery perforator. The flap size ranged from 7.5 cm x 2.8 cm to 13.0 cm x 5.0 cm. The wounds at the donor sites were covered with skin grafts.

RESULTSAll the 10 flaps and skin grafts were survived with primary healing. The patients were followed up for 6-12 months with satisfactory cosmetic results. The 2-point discrimination was 4-6 mm when the proximal end of saphenous nerve was not injured, and it was 9-10 mm when the nerve was injured or cut off. The patients could walk with no occurrence of ulcer in flaps or donor site.

CONCLUSIONSThe medial planta island flaps pedicled with anterior tibial artery perforator can effectively repair the small wounds around ankle with reliable blood supply.

OBJECTIVETo evaluate medium-long term patency of below-knee bypass on patients who suffered from diabetic lower limb ischemia.

METHODSClinical and follow-up data of 51 patients was retrospectively analyzed who underwent 56 below-knee bypass because of diabetes from November 2001 to December 2006. There were 35 male and 16 female with an average age of 68 years. They endured 26 months ischemic time lag in average, and had suffered from diabetes for 11 years. All of the patients were performed bypass to below-knee (posterior tibial, anterior tibial or peroneal) arteries. Kaplan-meier method was applied. The subgroups of different operative methods and different out-flow vessels were compared by Log-rank tests.

RESULTSAn average follow-up time of 23 months was achieved, and lost-follow-up rate was 15%. The total 1- and 5-year primary patent rates were 68% and 54% respectively, secondary patent rate were 70% and 60% respectively, limb salvage rates were 69% and 65%, survival rates were 82% and 60%. One year (3 years) of patent rate(s) of operative method subgroups of femoral-popliteal-infrageniculate bypass with composite grafts, femoral/popliteal-infrageniculate bypass with artificial grafts and femoral/popliteal-infrageniculate bypass with autologous veins were 70% (50%), 33% (33%) and 70% (70%) respectively. One year (4 years) of patent rate(s) of out-flow vessel subgroups of posterior tibial artery, anterior tibial artery and peroneal artery were 65% (60%), 80% (53%) and 77% (66%) respectively. However, both subgroups did not show any statistic differences by log-rank tests.

CONCLUSIONSPartial or whole autologous veins as bypass grafts should be chosen when infrageniculate bypass is considered in diabetic patients. Considerable patent rates are acceptable no matter what kinds of out-flow vessels are chosen.

Many complications have been reported during or after anterior cruciate ligament (ACL) reconstruction, including infection, bleeding, tibial tunnel widening, arthrofibrosis, and graft failure. However, arterial injury has been rarely reported. This paper reports a case of an anterior tibial arterial injury during bicortical tibial drilling in arthroscopic ACL reconstruction, associated with an asymptomatic occlusion of the popliteal artery. The patient had a vague pain which led to delayed diagnosis of compartment syndrome and delayed treatment with fasciotomy. All surgeons should be aware of these rare but critical complications because the results may be disastrous like muscle necrosis as in this case.

OBJECTIVETo summarize the technique and therapeutic effect of free posterior tibial artery perforator (PTP) flap for skin defect on the dorsum of hand or foot.

METHODSThe lower leg was divided into 6 sections equally from the level of tibial tuberosity to the connection of medial and lateral malleolus. The free PTP flap was designed along the inner edge of tibia within the proximal section 2 and 3. The flap was harvested with 2-3 bundles of the saphenous nerve included. The size of skin defects on the dorsum of hand or foot ranged from 3.0 cm x 7.5 cm to 6.0 cm x 12.0 cm.

RESULTSFrom Jan. 2009 to Dec. 2010, 11 cases were treated with free PTP flaps. All the flaps survived completely. The follow-up period ranged from 3 to 10 months. The flaps had good color and texture. Two point discrimination recovered to 7-10 mm, leaving linear scar at the donor site. The appearance and function of the hand or foot was satisfactory.

CONCLUSIONSThe free PTP flap is thin with good sensation, leaving less morbidity at donor site. The posterior tibial artery can be reserved. It is an ideal method for skin defect on the dorsum of hand or foot.
