聚丙烯酰胺水凝胶注射隆乳术后并发症处理

目的 探讨聚丙烯酰胺水凝胶注射隆乳术后各种并发症及处理方法.方法 自2003年2月至2007年2月收治45例聚丙烯酰胺注射隆胸术后病人,采用注射器抽取及手术切开直视下水凝胶取出术,其中20例取出同时行假体隆胸术.结果 本组病例治疗均获得了满意效果.结论 聚丙烯酰胺水凝胶取出术是目前治疗并发症的较好方法,假体隆胸术可以改善水凝胶取出后的乳房形态.     

聚丙烯酸胺水凝胶注射隆乳并发症处理方法的探讨

目的探讨聚丙烯酞胺水凝胶注射隆乳术后并发症处理方法。方法对28例聚丙烯酸胺水凝胶注射隆乳者,采用显露抽吸、刮除、部分腺体及肌肉切除等方法,清除其注射物,消除并发症。结果所有病例症状较术前有明显好转,效果满意。结论手术切开是处理聚丙烯酸胺水凝胶并发症较合理的方法,可以最大程度取出注射物。     

聚丙烯酰胺水凝胶注射隆乳术后并发症处理临床分析

目的探讨聚丙烯酰胺水凝胶注射隆乳术后并发症的处理方法。方法本组病例12例,注射聚丙烯酰胺水凝胶隆乳术后14～51个月,出现乳腺感染脓肿2例,多发性硬结形成或移位8例,有恐惧心理要求取出水凝胶2例。所有患者术前均行彩超或MRI检查定位。经乳晕切口取出9例,其中3例行一期硅胶假体隆乳术,2例乳腺脓肿感染经乳房下皱襞切口切开引流。结果随访3～12个月,患者均对取出术效果满意,乳房外形对称,无明显硬结扪及,无感染复发。术后B超检查仍可见少量水凝胶存在于乳腺组织中。结论水凝胶取出术采用乳晕切口直视下手术较为合理,对于乳腺脓肿选择乳房下皱襞切口。是否一期硅胶假体隆乳取决于胸大肌组织受累程度、患者的要求和术者的经验。水凝胶注射隆乳术后假体很难彻底清除,应加强对患者的术后随访和心理疏导。     

聚丙烯酰胺水凝胶注射隆鼻术后并发症的处理及临床分析

目的探讨聚丙烯酰胺水凝胶注射隆鼻术后并发症产生的原因及相关的处理。方法通过总结处理52例聚丙烯酰胺水凝胶注射隆鼻术后并发症的经验体会，分析并发症产生的原凶及处理补救措施。结果52例中产生的并发症有感染、肉芽肿、皮肤破溃、外形不良、疼痛和严重的心理压力等。每例有1～4种并发症。根据不同情况采取不同处理方法，并选取适当病例在取出聚丙烯酰胺水凝胶的同期或二期置入硅胶或膨体聚四氟乙烯假体，多数病例能取得较满意的效果，少数病例遗留后遗症和长久的心理压力或鼻部隐痛。结论聚丙烯酰胺水凝胶注射隆鼻术后并发症种类多样，与聚丙烯酰胺水凝胶的同有性质、鼻部软组织解剖特点有关。出现并发症后反复抽吸，会导致聚丙烯酰胺水凝胶分布更加紊乱，损伤加重。只有采取综合的手术方法才能较彻底地清除聚丙烯酰胺水凝皎。     

Case Reports: Fractures of Threaded Cups: Rare Complications of a Well-established Implant

The use of cementless threaded cups in THA is a well-established treatment. Fractures of the cups are rare complications recorded in individual cases with material defects being discussed as the primary cause. We analyzed three cases of fractured cups. Although all three cups were well fixed to existing bone, we observed deficient osseous backing dorsocranially and abrasion particles. There were no signs of femoroacetabular impingement or infection. The cups showed corrosion debris. Scanning electron microscopic investigations showed characteristics of fretting and fretting-related corrosion. We concluded the fractures occurred because of fretting combined with inadequate bony support leading to fatigue of the material and subsequent fracture.

Migration of Implants: A Problem with Injectable Polyacrylamide Gel in Aesthetic Plastic Surgery

Polyacrylamide gel (PAAG) has been used as a soft tissue filler material for cosmetic purposes in Europe and China since 1997. The various complications of PAAG have been reported. A total of 15 patients who received PAAG injections at other institutions were treated for gel migration in the authors’ hospitals. During treatment, the authors found that the injected PAAG had not formed capsules within the muscle and was encapsulated only by thin fibrous tissue in skin and mammary glands. Consequently, the filler material migrated easily because of muscular activity or the influence of gravity, especially when the capsule was broken by incorrect massage or incidental force. It is suggested that PAAG should not be injected into muscular tissue or subcutaneous areas with active movement, such as joints and muscles involved in facial expression with thin skin. After years of gel implantation, the thinned capsule may result in an increasing incidence of this complication. Management and some clinical findings in relation to the complication also are discussed.     

Successful Treatment of Recurrent Liver Metastases from Gastric Cancer by Repeated Hepatic Resections: Report of a Case

We describe herein the case of a patient in whom recurrent liver metastases from gastric cancer were successfully treated by performing repeated hepatic resections. A 63-year-old man underwent a total gastrectomy with regional lymph node dissection for an advanced gastric cancer on November 17, 1992, the pathological findings of which confirmed a diagnosis of well-differentiated tubular adenocarcinoma, ss, INFα, ly1, v0, n1(+). Follow-up computer tomography (CT) and ultrasonography scans done 7 months after the gastrectomy revealed a metastasis in the liver S5, and a partial resection of S5 was performed on July 5, 1993. Subsequently, on November 17, 1994, an anterior segmentectomy of the liver was performed for a liver metastasis in the liver S8, then on August 11, 1998, a partial resection of the liver S6 was performed for a metastasis in the liver S6. The pathological findings of each liver specimen resected were compatible with metastatic adenocarcinoma from the primary gastric cancer. The liver tumors were expansive-growing tumors with capsules and massive necrosis. The patient is currently well with no evidence of recurrence on repeat CT scans, 6 years 6 months since-the initial gastrectomy, and 5 years 10 months since the first hepatic resection.

Superficial Basal Cell Carcinoma of the Face Successfully Treated with Ingenol Mebutate 0.05% Gel: Case Report and a Review of the Literature

A 64 year-old Caucasian male patient with a long history of ultraviolet light exposure and multiple actinic keratoses presented with a large, erythematous, and scaly plaque on his forehead. Biopsies revealed superficial basal cell carcinoma (sBCC). Because the patient wanted the shortest possible topical regimen, his sBCC was treated with two overnight ingenol mebutate (IM) 0.05% gel applications. He tolerated the local skin reaction (LSR) well, and at approximately six weeks post-treatment, biopsies showed no evidence of sBCC. The patient was happy with the cosmetic outcome and has remained free of clinical recurrence for 18 months. Although IM gel is only FDA approved for the treatment of actinic keratosis, it has also been used off-label to treat other epithelial lesions, including basal cell carcinoma (BCC), anogenital warts, and Bowen’s disease. One clinical trial, multiple case series and case reports, and now this report, have demonstrated IM’s utility in treating BCC. IM treatment is therefore a promising alternative to surgery for select BCC, with major advantages, including a short treatment duration and generally favorable cosmetic outcome.
