【摘要】 目的 探讨起搏器植入术后并发局部慢性溃疡伴感染的综合治疗方法。 方法 2005年1月-2010年5月，收治4例心脏起搏器植入术后并发局部慢性溃疡伴感染的患者。男3例，女1例；年龄3~79岁。心脏起搏器植入术后囊袋感染致皮肤破溃伴慢性溃疡2例，起搏器植入后局部张力过高所致局部慢性溃疡2例，其中2例患有2型糖尿病。所有患者均经过长期严格换药保守治疗3个月以上。手术彻底切除感染创面及相关包囊并尽可能剪除部分导丝，甚至更换导丝，根据情况原位或异位植入起搏器，并放置橡皮引流条，应用敏感抗生素5~7 d防治感染。术后2周拆线，主要观察患者切口对合情况，是否存在红肿、硬结、血肿、积液或化脓情况。 结果 4例患者术后均Ⅰ期愈合；4例均获随访，随访时间7~11个月，平均9个月。原创面愈合好，无感染及溃疡发生。 结论 通过外科手术综合治疗难治性心脏起搏器植入术后并发症，能取得满意疗效。【Abstract】 Objective To explore comprehensive treatment options for local chronic ulcer with infection after the pacemaker implantation. Methods From January 2005 to May 2010, four patients (3 males and 1 female; 3-79 years old) with intractable ulcer with infection after pacemaker implantation were admitted. Pacemaker pocket infection induced chronic ulcer was in two, and tension induced chronic ulcers were in two. Two of the four patients were type II diabetes. All of the four patients underwent strict conservative treatment at least for 3 months prior to surgical treatment. Surgical treatment involved complete excision of infected tissue surrounding the pacemaker pocket and removal of all unnecessary lengths of pacemaker lead, even complete replacement of the original lead. Depending on the specific situation, pacemakers were either placed in their original position or a new position with a latex drainage strip. Patients then received a course of antibiotic treatment ranging from 5 to 7 days. Results All of the four patients achieved healing by first intention, and were followed up for 7-11 months, with an average of 9 months follow up. All patients achieved the satisfactory results. Conclusion A comprehensive treatment is effective on local chronic ulcer with infection after the pacemaker implantation.
ObjectiveTo explore the effectiveness of modified inferior pedicle technique with inverted T pattern for severe breast hypertrophy.MethodsBetween January 2016 and May 2017, 15 patients of severe breast hypertrophy had undergone breast reduction using inferior pedicle technique with inverted T pattern combined with dermal suspension sling technique. The patients were 20 to 49 years old, with an average age of 31.6 years. Body mass index ranged from 24.9 to 32.5 kg/m2, with an average of 30.8 kg/m2. Among them, 11 cases had a history of childbearing. The degree of breast ptosis was rated as degree Ⅱ in 6 cases and degree Ⅲ in 9 cases. The unilateral breast reduced 615 g on average (range, 480-1 050 g).ResultsThe skin flap necrosis at the " T” trilateral junction occurred in 3 cases, and healed after dressing changes. The incisions of 12 cases healed and no fat liquefaction, hematoma, or seroma occurred. The sensation of nipple and areola declined at early period after operation in 2 cases, and gradually recovered. All patients were followed up 6-18 months (mean, 13 months). The shapes of bilateral breasts and the height and symmetry of nipple-areolar complex were good, and no obvious scar was found. The effectiveness was evaluated by surgeon and showed that there were 12 cases with satisfactory breast shape and 3 cases with unsatisfactory breast shape; 3 cases with obvious scare and 12 cases with insignificant scar; 13 cases with normal nipple sensation and 2 cases with hypoesthesia; 11 cases with symmetric nipples and 4 cases with asymmetric nipples. The effectiveness was evaluated by patients and showed that the satisfactory breast shape in 10 cases, relatively satisfactory breast shape in 4 cases, and unsatisfactory breast shape in 1 case; highly acceptable scar in 9 cases, moderately acceptable scar in 4 cases, and unacceptable scar in 2 cases; overall satisfactory in 10 cases, relatively satisfactory in 4 cases, and unsatisfactory in 1 case, with the overall satisfaction rate of 93.3% (14/15).ConclusionFor severe breast hypertrophy, the modified inferior pedicle technique with inverted T pattern can obtain satisfactory appearance and avoid the mastoptosis.
ObjectiveTo investigate the effectiveness of internal mammary artery perforator (IMAP) propeller flap repair combined with radiotherapy for chest keloid in female patients.MethodsBetween January 2015 and December 2016, 15 female patients with chest keloids were treated, aged 28-75 years (mean, 45.2 years). The keloid disease duration was 1-28 years (median, 6 years). The causes of disease included secondary keloid caused by folliculitis in 7 cases, cardiac surgery in 4 cases, skin abrasion in 2 cases, mosquito bite in 1 case, and unknown etiology in 1 case. The size of keloid ranged from 5 cm×3 cm to 17 cm×6 cm. The IMAP propeller flaps were used to repair the defects after chest keloid excision. The size of flaps ranged from 7 cm×5 cm to 14 cm×8 cm. The donor sits were sutured directly. The routine radiotherapy was performed after operation.ResultsAll IMAP propeller flaps survived well, and the donor sites healed by first intention. All 15 patients were followed up 12-24 months (mean, 16 months). No telangiectasia or incision dehiscence occurred. No radiation-related carcinogenesis occurred during follow-up. The patients were satisfied with the breast shape and symmetry after operation. The symptoms of pain and itching relieved at keloid area in 13 cases (86.7%), with no obvious recurrence of keloid at the donor site and the primary site. Only 2 cases (13.3%) recurred and were treated with continuously conservative treatment.ConclusionIMAP propeller flap is an ideal reconstruction method for repairing the wounds after chest keloid excision in female patients, which can preserve the good breast shape. The IMAP propeller flap repair combined with early postoperative radiotherapy can effectively reduce the recurrence rate, and the effectiveness is satisfactory.
