Reconstruction of the pelvis after traumatically induced bilateral partial hemipelvectomy: a case report.

BACKGROUND: Traumatic hemipelvectomy is a catastrophic fracture of the pelvis as a result of high-energy trauma, such as in a car accident. There have been few case reports of traumatic hemipelvectomy because many of these patients die before they are transferred to a hospital. However, an increasing number of patients are being saved and admitted to hospital due to improvements in resuscitation and the emergency response system. Accordingly, there has been a growing body of reports on the management and reconstruction of traumatic hemipelvectomy. CASE PRESENTATION: A healthy 20-year-old Japanese man was trapped beneath a 3-ton steel frame while working on a crane. We describe here a very challenging case of traumatically induced bilateral partial hemipelvectomy with successful reconstruction of our patient's pelvis using a unilateral anterolateral thigh flap. CONCLUSION: To the best of our knowledge, there have been few reports of bilateral hemipelvectomy and our case is the first to be successfully treated with a unilateral anterolateral thigh flap.

Combination of meshed dermis graft and cultured epithelial autograft for massive burns: Three case reports.

RATIONALE: This study reviewed the use of a combination of meshed dermis graft and cultured epithelial autografts (CEA) made in Japan "JACE" (JACE; Japan Tissue Engineering Co., Ltd. Japan) for the treatment of massively burns. JACE is a Green-type CEA. We recently described a method in which we prepare the wound bed for burned patients by using artificial dermis and graft with JACE on a meshed 6:1 split-thickness autograft. In this report, we used a meshed 3:1 split-thickness dermis graft without epithelial cells. There are several reports of combination of using CEA on meshed split-thickness autograft, however this is the first report of using CEA on meshed split-thickness dermis graft. PATIENT CONCERNS AND DIAGNOSIS: Between March 2015 and August 2017, 3 burn patients were enrolled in this study. The patients ranged in age from 51 to 66 years. All 3 patients suffered severe burn injury that caused by flame. % Total Body Surface Area (TBSA) burned were ranged from 37.5% to 69%. INTERVENTIONS: All patients received surgical treatment with tangential excision within a week from admission. We implanted artificial dermis immediately after debridement. Basically, we applied meshed 6:1 split-thickness autografts to the wound bed and covered with JACE. However, in the absence of split-thickness autografts, we used a meshed 3:1 split-thickness dermis graft instead of a meshed 6:1 split-thickness autograft. OUTCOMES: At 3 weeks after the transplantation of JACE, the take rate for JACE sheets was >60% on the meshed 3:1 split-thickness dermis graft. Furthermore, almost all of the burn wounds had healed at 6 weeks after surgery. LESSONS: We observed good results by grafting JACE on meshed 3:1 dermis graft. With this new method, it is possible to cover a large burn wound by harvesting tissue from only a small site.

Chronic Expanding Hematoma Following Abdominoplasty.

Chronic expanding hematoma (CEH) is a relatively rare complication of trauma or surgery. We report a patient with CEH as a late complication of abdominoplasty. A 58-year-old woman underwent conventional abdominoplasty and thereafter refused to use a compression binder, citing discomfort. One month postoperatively, she presented with a gradually enlarging, painful abdominal mass. The results of ultrasonography and computed tomography were highly suspicious for CEH. The lesion was completely removed, together with surrounding fibrous tissue. Histopathology revealed a chronic hemorrhage collection with a fibrous capsule, consistent with CEH. This condition as a late complication of abdominoplasty has not previously been reported in the literature. However, an online medical consultation site features several abdominoplasty patients asking about persistent hematomas that sound suspicious for CEH. CEH might be underdiagnosed by surgeons. Although a postoperative binder may increase the risk of skin necrosis and deep vein thrombosis, appropriate compression treatment is necessary to prevent hematoma formation.
