Objective To improve the knowledge of inflammatory bowel disease complicated with venous thromboembolism for better diagnosis and treatment. Methods One case of patient with ulcerative colitis complicated with a multiple vessel thromboembolism ( pulmonary arterial, deep vein of lower limb, and superior mesenteric vein) was analyzed, and related literatures were reviewed. Results The patient resulted in pulmonary thromboembolism ( PTE) recurrence because of irregular treatment. In addition to deep vein thrombosis of the lower extremity, a new discovery of the superior mesenteric vein embolism ( MVT) was diagnosed. The bleeding risk of heparin or lowmolecular weight heparin ( LMWH) for treatment is low, while that of warfarin is high. Conclusions Venous thromboembolism ( VTE) has a close relationship with inflammatory bowel disease ( IBD) such as ulcerative colitis. The symptomis not so typical that it is easy to misdiagnosis and missed diagnosis. It is noted that mesenteric venous thrombosis ( MVT) should be excluded in IBD patients suffering from VTE, if the source of embolus is not clear. Suitable treatment should be considered according to the risk stratification of VTE and risk-benefit ratio because of a high bleeding risk.
Objective? To investigate the pathogenesis, diagnosis, and treatment of unilateral gluteal muscle contracture. Methods Between January 1990 and September 2009, 41 patients with unilateral gluteal muscle contracture were treated and the cl inical data were retrospectively analysed. Among them, 24 were male and 17 were female with an age range from 6 to 29 years (mean, 12 years). Thirty-nine patients had a definite history of repeat intragluteal injection. The locations were the left side in 9 cases and the right side in 32 cases. The main cl inical manifestations included lameness and abnormal gait. The medical examination showed pelvic obl ique and relative inequal ity of lower l imbs with a mean difference of 2.1 cm (range, 1.2-3.8 cm) in the distance form navel to malleolus medials. The X-ray films of pelvis showed outpouching trochanter of femur and pelvic obl ique. The CT scans showed no abnormal finding except pelvic obl ique and gluteal muscle contracture. The arc longitudinal incision was made into the posterolateral area nearby the greater trochanter and then lysis of the gluteal muscles was performed, followed by the skin traction of both legs and rehabil itation exercise. Results All incisions healed by first intention. Forty-one patients were followed up 1-20 years (mean, 5 years), and the signs of gluteal muscle contracture disappeared. After 1 year of operation, 34 patients had equal leg length, 5 patients had mild pelvic obl ique, and 2 patients had obvious pelvic obl ique. According to LIU Guohui et al. evaluation standard, the results were excellent in 33 cases, good in 6 cases, and poor in 2 cases with an excellent and good rate of 95.12% at 1 year after operation. Conclusion Unilateral gluteal muscle contracture leads to pelvic obl ique and inequal ity of lower l imbs, and it can be cured with the surgical release of the gluteal muscle contracture by the arc longitudinal incision into the posterolateral area nearby the greater trochanter, combined with postoperative skin traction and rehabil itation exercises.
Objective To explore the feasibil ity, indications, and effects of vacuum seal ing drainage (VSD) combined with flaps for repairing skin and soft tissue defects of lower l imbs. Methods From June 2006 to November 2009, 15 patients with skin and soft tissue defects of lower l imbs were treated with VSD combined with flaps (VSD group, n=5) and only flaps (non-VSD group, n=10). In VSD group, there were 3 males and 2 females with an average age of 46 years (range, 32-69 years), including 3 cases of traffic accident injury, 1 case of skin necrosis after amputation, and 1 case of plate exposureafter operation. The locations were lower leg in 1 case, ankle in 2 cases, dorsum of foot in 1 case, and forefoot in 1 case. The defect size ranged from 6.5 cm × 6.0 cm to 23.0 cm × 17.0 cm. The disease course ranged from 2 hours to 2 months. In non- VSD group, there were 5 males and 5 females with an average age of 50 years (range, 23-58 years), including 6 cases of traffic accident injury, 1 case of crush injury in earthquake, 1 case of osteomyel itis, and 2 cases of plate exposure after operation. The locations were lower leg in 1 case, ankle in 3 cases, forefeet and dorsum of feet in 4 cases, and heel in 2 cases. The defect size ranged from 4 cm × 4 cm to 20 cm × 12 cm. The disease course ranged from 1 hour to 2 months. There was no significant difference in general data between 2 groups (P gt; 0.05). Results In VSD group, the preoperative hospital ization days, postoperative hospital ization days, and total hospital ization days were (11.8 ± 9.5), (35.4 ± 28.3), and (47.2 ± 35.8) days, respectively; the size of flap was (232.8 ± 142.0) cm2; and the infection rate after VSD-use was 0. In non-VSD group, the preoperative hospital ization days, postoperative hospital ization days, and total hospital ization days were (25.8 ± 12.4), (33.9 ± 28.1), and (59.7 ± 32.4) days, respectively; the size of flap was (97.3 ± 93.6) cm2; and the infection rate after 8 to 14 days of regular therapy was 80%. There were significant differences in the preoperative hospital ization days and the size of flap between 2 groups (P lt; 0.05). All flaps were al ive except 3 partial necrosis (1 case in VSD group, 2 cases in non-VSD group). The 3 flaps healed by skin grafting and suturing. The donor sites healed by first intention. All patients were followed up 5-41 months (22.1 months on average). All flaps were good in color, texture, and wear abil ity. Conclusion It is effective to apply VSD combined with proper flap to repair skin and soft tissue defects of lower l imbs, which can cut down infection rate, improve blood supply, shorten the preoperative hospital ization days, and facil itate heal ing, but whether it can shorten the postoperative hospital ization days and total hospital ization days need further research.
To summarize the effectiveness of the improv ed surgical techniques in fasciocutaneous flaps of the limbs. MethodsFrom February 1999 to December 2005, 58 patients (39 males, 19 females, aged 1068 years) underwent repairs of the skin defects with improved fasciaocu taneous flaps of the limbs. Twentyone patients had the skin defects in front of the tibial bone in the middle and lower parts, 12 patients had the skin defect s in the heels, 16 patients had the skin defects in the ankles, 3 patients had t he skin defects around the knees, 1 patient had a wide sacrococcygeal bedsore, and 5 patients had the skin defects in the wrists and hands. The wounds ranged in size from 5 cm×3 cm to 18 cm× 12 cm. According to the wound lo cations, the following flaps were selected: 4 cutaneous antebrachii medialis nerve and basilic vein fasciocutaneous flaps, 1 cutaneous antebrachii lateralis nerve and cephalic vein fasciocutaneous flap, 3 saphenous nerve and great saphenousvein fasciocutaneous flaps, 1 cutaneous nerve of thigh posterior fasciocutaneous flap, 32 reverse sural nerve and saphenous vein fasciocutaneous flaps, and 17 reverse saphenous nerve and great saphenous vein fasciocutaneous flaps. The dissected flaps ranged in size from 6 cm× 4 cm to 18 cm× 13 cm. The donor wounds underwent straight sutures in 39 patients, and the skin grafting (6 cm×3 cm to 13 cm× 6 cm) was performed on 19 patients after the donor wounds were closed. Results The wounds healed by first intention, and the flaps survived completely in 54 patients. The flaps developed partial necrosis in 4 patients. The followup for 120 months (average, 8 months) revealed that the flaps had a satisfactory appearance with a soft texture and the function was also satisfactory. Conclusion A fasciocutaneous flap of the limbs is an ideal flap for repairing defects in the skins and soft tissues of the limbs. The survival rate of the flap can be further improved by an improvement of the surgical techniques.
Objective To explore the clinical effect of latissimus dorsi musculocutaneous flap with a few muscle in repairing the soft tissue defect of lower limbs. Methods From June 2000 to December 2006, 8 patients with soft tissue defects of lower limbs were repaired with the latissimus dorsi musculocutaneous flaps. There were 6 males and 2 females, aged from 2569 years. The locations were heel in 3 cases, dorsum pedis in 2 cases, anticnemion in 2 cases, and the right leg (squamous carcinoma) in 1 case. The area of soft defect ranged from 10 cm×7 cm～18 cm×12 cm. The flap in size ranged from 15 cm×8 cm to 22 cm×15 cm. Results Of all the flaps,6 survived,1 had vascular necrosis 2 hours after operation and survived by skin grafts, 1 had delayed healing because of infection. The wound and donor site achieved primary healing. The followup for 3 to 12 months revealed that all the flaps had a good appearance. The function of donor site was as normal. Conclusion It is an ideal method to repair the softtissue defect of lower limbs with latissimus dorsi musculocutaneous flap.
Objective To evaluate the long-term function of the traumaticallydamaged joint after its repair with transplantation of a fresh or a frozen allogenic joint. Methods From March 1977 to September 1993, 13 patients (9 males, 4females; age, 17-55 years) with traumatically-damaged joints underwent transplantation of the fresh or the frozen allogenic joints. Five patients had 5 damagedmetacarpophalangeal joints, 6 patients had 9 damaged interphalangeal joints, and 2 patients had 2 damaged elbow joints. So, the traumatic damage involved 13 patients and 16 joints. All the metacarpophalangeal joints and the interphalangeal joints were injured by machines and the 2 elbow joints were injured by road accidents. The patients were randomly divided into 2 groups: Group A (n=7) andGroup B (n=6). The 7patients with 8 joints in Group A underwent transplantation of fresh allogenic joints; the 6 patients with 8 joints in Group B underwent transplantation of frozen allogenic joints. The allogenic joint transplants were performed in the period from immediately after the injuries to 6 months after the injuries. The motion ranges of the transplanted joints and the X-ray films were examined after operation, and the immunological examination was performed at 8 weeksafter operation. Results The time for synostosis was 5-8 months in Group A, but4-6 months in Group B. In Group A, at 2 years after operation the metacarpophalangeal flexion was 30-40° and the interphalangeal flexion was 20-30°; however,at 6 or 7 years after operation the interphalangeal flexion was only 10-20°. The patients undergoing the transplantation with fresh elbow joints had the elbowflexion of 60° and the elbow extension of 0°, and had the forearm pronation of 30°and the forearm supination of 30°. But in Group B, at 2 years after operation the metacarpophalangeal flexion was 6070° and the interphalangeal flexionwas 40-50°; at 6 or 7 years after operation the interphalangeal flexion was still 40-50°. However, the patients undergoing the transplantation with frozen elbow joints had the elbow flexion of 90° and the elbow extension of 0°, and hadthe forearm pronation of 45° and a forearm supination of 45°. The joint motion ranges, the Xray findings, and the immunological results in the patients undergoing the transplantation of the frozen allogenic joints were significantly better than those in the patients undergoing the transplantation of fresh allogenicjoints. There was a significant difference in the immunological examination between Group A and Group B (IL2, 21.64±3.99；CD4/CD8,3.88±0.82 vs.IL-2,16.63±3.11；CD4/CD8, 2.53±0.23, P＜0.01). Conclusion Repairing the traumatically-damaged joints with frozen allogenic joints is a better method of regaining the contour, movement, and complex motion of the hands.
OBJECTIVE: To study the clinical result of treating firearm-wound with the vessel pedicel tissue flap. METHODS: From May 1992 to October 2000, 21 cases of firearm-wound of upper limbs underwent transplantation with the vessel pedicel tissue flap. Of them, the locations of the wound were upper arm in 11 cases, forearm in 7 cases, hand in 3 cases. The size of wound was 1.0 cm x 0.5 cm to 8.0 cm x 6.5 cm; the wound course was 3 minutes to 8 hours with an average of 3 hours and 30 minutes. The patients were followed up 3 months to 2 years. RESULTS: In 21 cases, the results were excellent in 19 cases and poor in 2 cases. The good rate was 90.5%. CONCLUSION: Treatment of firearm-wound with vessel pedicel tissue flap has the good effect.
OBJECTIVE: To summarize the importance of surgical management to repair vascular injury in limbs salvage, and to analyze the influence factors in the management. METHODS: From 1993 to 2000, 42 cases of 58 vascular injuries were reviewed; there were 37 males and 5 females, aging from 12 to 70 years old. Emergency operations were performed in 38 cases and selective operations in 4 cases from 1 hour to 45 days after injury. There were 22 cases of complete rupture in 32 blood vessels, 5 cases of partial rupture in 6 blood vessels, and 15 cases of vascular defect in 20 blood vessels, with 5 cm to 10 cm defect. The operation management included end-to-end anastomosis in 22 cases, side-to-end anastomosis in 1 case, vascular repair in 5 cases and vascular grafting in 14 cases. All of the cases were followed up for 6 months to 7 years. RESULTS: In those received emergency operations, it was successful in 35 cases, with amputation in the other 3 cases; after operation, there were 5 cases of post-operative angio-crisis, 1 case of hematoma and 1 case of pseudoaneurysm. In those received selective operation, all succeeded but 1 case of post-operative angio-crisis. After the follow-up, except for 3 cases of amputation, the other limbs survived; and function of the survived limbs recovered satisfactorily after operation except poor recovery in 7 cases of replantation of the limbs. CONCLUSION: To repair vascular injury immediately, to manage angio-crisis and to remove influence factors is the key to save the injured limbs and to maintain the function of them.
OBJECTIVE: To define how to preserve the severed limbs to prolong the period of replantation. METHODS: The original articles about preservation of severed limbs in recent years were reviewed, it was suggested that the period of replantation was determined by the injury of skeletal muscle. RESULTS: When the environment of severed limbs was changed, the injures of skeletal muscle could be decreased. CONCLUSION: After the severed limbs are reasonably preserved, the period of replantation may be prolonged.
