【摘要】 目的 探討2型糖尿病合并下肢血管病變血管內介入治療的臨床意義。 方法 2009年1-5月對4例2型糖尿病合并下肢血管病變患者，根據血管狹窄情況選擇不同介入治療方式，行下肢動脈造影及動脈球囊擴張或支架成形術。 結果 4例患者均有表現靜息痛及間歇性跛行，下肢血管超聲顯示糖尿病下肢動脈有不同程度的斑塊、狹窄與血栓形成，病變累及下肢股動脈、髂動脈及脛前、足背動脈。介入治療后患者下肢血管灌注得到明顯改善，靜息痛及間歇性跛行明顯改善，皮溫改善，需要截肢患者截肢平面顯著降低。 結論 通過下肢血管DSA造影檢查，準確了解糖尿病患者下肢血管的阻塞部位及程度，在保守治療基礎上選擇不同方式的介入治療，有助于下肢血管病變的明顯改善。【Abstract】 Objective To investigate the clinical significance of intervention therapy for patients with type 2 diabetes combined with vascular lesions of lower extremities. Methods From January to May, 2009, four diabetic patients with vascular lesions of lower extremities were examined by Doppler ultrasonography and digital subtration angiography (DSA). All patients were treated by percutaneous transluminal angioplasty (PTA) or stenting therapy. Results Stenoses and obstruction of lower extremity blood vessels were observed in all patients. After intervention therapy, vascular perfusion of lower extremities was improved and signs of rest pain and intermittent claudication were relieved; the skin temperature was improved, and the amputation level was apparently decreased. Conclusion It suggests that DSA is effective in judging extend and location of blood vessel stenosis,and the interventional treatment could lead to a satisfying prognosis.
OBJECTIVE: To sum up the experience of clinical application of distal base sural island flap. METHODS: From January 1997 to April 1999, the posterior island flap of leg pedicled with sural nerve and its nutrient vessels was applied to repair heel or dorsum of foot in 6 cases, chronic ulcer of heel in 2 cases, chronic osteomyelitis in 2 cases, scar contracture of bone defect accompanying fistulation in 1 case. The range of flap was 5 cm x 8 cm to 8 cm x 12 cm. RESULTS: All the flaps survived completely without vascular crisis. All the wounds healed by first intention. Followed up 3 to 12 months, no ulcer, osteomyelitis, fistulation were recurrence, and the sensation of flap was recovered slightly. CONCLUSION: The flap do not damage critical blood vessels and nerves, the donating region is hidden. The manual of operation is simple and blood supply of flap is sufficient. It can repair the defect of soft tissue on heel and dorsum with high survival rate.
目的 總結臨床經驗，提高診治水平。方法 總結我院1992年4月至1998年6月期間5例甲狀腺術后癔病性搐搦的臨床資料。結果 5例均為女性，術前血清鈣、磷濃度正常，無癲癇史。4例行甲狀腺側葉加峽部切除術，1例行甲狀舌骨囊腫切除術。4例于術后1小時50分至3小時20分突發手足搐搦。1例術后5小時25分出現手腕以遠麻木。查體： Chvostek氏征及Troussetau氏征陰性，急查血清鈣、磷及PTH濃度正常，靜脈補鈣無效。結論 甲狀腺術后出現搐搦，如補鈣無效，應考慮癔病的可能。其特點為： 女性，具有一定的文化知識，發病時間早，血清鈣、磷及PTH正常，靜脈補鈣無效，需用心理暗示及鎮靜治療。
Objective To study the method and effect of free rectusabdominis muscle flaps with intermediate split thickness skin graft in repairing defects on legs and ankles.Methods From May 1998 to December 2002, 11 cases of defects on legs(2 cases) and on ankles( 9 cases) were repaired by use of unilateral free rectus abdominis flap with skin graft. The soft tissue defects were accompanied by osteomyelitis or the exposure of bone or tendon.The disease course was 1 month to 10 years. The defect size ranged 3 cm×4 cm to 8 cm×14 cm. The area ofrectus abdominis muscle flaps was 4 cm×6 cm to 8 cm×15 cm. Results All patients were followed up 6 months to 4 years after operation. All rectusabdominis flaps survived with good appearances and functions.The primary healing was achieved in 8 cases, intermediate split thickness skin graft necrosed in 3 cases and the wound healed after skin re-graft.Conclusion Free rectus abdominis flap is a proper option for repair of the soft tissue defects or irregular woundson legs and ankles. It has the advantages of abundant blood supply, b anti-infection ability, good compliance and satisfied appearance.
Objective To evaluate the effectiveness of interference screw and flexor hallucis longus tendon as augmentation material in repair of chronic Achilles tendon rupture. Methods From October 2004 to June 2007, 32 patients (35 feet) with chronic Achilles tendon rupture were treated, including 21 males (22 feet) and 11 females (13 feet) and aging 32-85 years. The disease course was 4-132 days. There were 29 patients with hoofl ike movements history and 3 patients withoutobvious inducement. The result of Thompson test was positive in 31 cases (33 feet). The score was 56.09 ± 7.25 according to the American Orthopaedic Foot and Ankle Society ankle-hindfoot scoring system (AOFAS). MRI indicated that the gap of the chronic Achilles tendon rupture was 0.5-5.0 cm. Medial foot incision associated with medial heel incision or only medial heel incision was made to harvest flexor hallucis longus tendon. The tendon should be 3 cm longer than the end of the Achilles tendon, then fix the tendon to the calcaneus. Results Wound dehiscence occurred and wound healed after dressing change in 1 case; wound healed by first intention in other patients. Thirty-two patients were followed up for 12-32 months (mean 19.4 months). The AOFAS score was 94.22 ± 4.63, showing statistically significant difference when compared with that before operation (P lt; 0.01). The results were excellent in 28 cases, good in 3 cases and fair in 1 case. No sural nerve injury, posterior tibial nerve injury, plantar painful scar, medial plantar nerve injury and lateral plantar nerve injury occurred. Conclusion Flexor hallucis longus tendon transfer offers a desirable outcome in operative recovery, tendon fixation and compl ications.
OBJECTIVE: To determine the long-term results and possible complications of the posterior tibialis transfer in correction of the foot-drop in leprosy patients, and to compare the results by the circum-tibial and interosseous routes. METHODS: From January to October 2001, 37 cases (treated from October 1989 to October 1999) were followed up. Walking gait, active dorsiflexion and plantar flexion of the ankle joint, deformities of the feet, and patients’ satisfaction were recorded. RESULTS: Of 37 patients, 22 were treated by circum-tibial transfer, 15 by interosseous transfer. All patients’ Achilles tendons were lengthened. Excellent and good results were obtained in 30 cases (86%). The active dorsiflexion was better by interosseous route than by circum-tibial route. Out of 35 patients followed up for 2-11 years (4 years on average), 14 had talipes varus in 22 by circum-tibial transfer, 2 had talipes varus in 13 by interosseous transfer; there was significant difference between two routes (P lt; 0.05). The complications included drop-toe(5 cases), muscle atrophy (4 cases), tendon rupture (1 case) and tendon adhesion (1 case). CONCLUSION: Tibialis posterior transfer with elongation of tendo Achilles can obtain excellent results in treating foot-drop due to leprosy. Interosseous route is preferred and physiotherapy is emphasized pre- and postoperatively.
