AbstractAbstract PDF
A Morel-Lavallée lesion (MLL) is a pathologic fluid collection within an abnormally formed space, resulting from an internal degloving injury between the muscle fascia and subcutaneous fat layer. Due to its resistance to conservative treatments such as drainage or compression dressing, various therapeutic methods have been developed for MLL. However, no standardized guidelines currently exist. Recently, endoscopic debridement and cutaneo-fascial suture (EDCS) has been introduced for the treatment of MLL, particularly for large lesions resistant to conservative approaches. While this procedure is known to be effective, limited reports are available on potential complications. The authors present a case of skin necrosis following EDCS for a massive MLL.

AbstractAbstract PDF
A Morel-Lavallée lesion results from a degloving injury between the muscle fascia and the subcutaneous layer. It is most commonly found in the trochanteric area but can occur at other sites. The treatment of the condition varies according to the medical circumstances, as well as the size and chronicity of the condition. A case of large (18×6 and 10×5 cm) bilateral posttraumatic Morel-Lavallée lesions with no underlying bone fracture is presented; the case occurred in a 49-year-old male patient 4 weeks posttrauma. Ultrasound scans showed bilateral large collections of anechoic fluid, which were aspirated under ultrasound guidance and further managed by compression bandages. There were no further complications. The objective of this case report is to present this unique and educational case, as well as to provide an overview of the pathophysiology, diagnosis, and management of Morel-Lavallée lesions. We conclude by discussing the importance of having a high index of suspicion to ensure early detection and prompt treatment of such lesions to avoid complications.

AbstractAbstract PDF

A Morel-Lavallée lesion is a closed degloving injury caused by traumatic separation of the skin and subcutaneous tissue from the underlying fascia. However, since physicians tend to focus on treating the bone fracture, hemodynamic instability accompanying a Morel-Lavallée lesion can sometimes be overlooked. We report the case of a hemodynamically unstable 73-year-old man who had a Morel-Lavallée lesion of the thigh, but no femur fracture. Angiography showed active bleeding from the muscular branch of the right deep femoral artery, which was then successfully embolized.

AbstractAbstract PDF

A Morel-Lavallée lesion is a post-traumatic closed degloving soft tissue injury after blunt trauma. Infection and skin necrosis frequently occur if it is not treated properly in the early stages. However, there is no clearly established treatment algorithm. In the acute stage, it is mainly treated with aspiration, simple compression, and incisional drainage. In the chronic stage, sclerotherapy is usually performed. If skin necrosis develops, the necrotic tissue is resected and a skin graft is needed. We describe a case of acute Morel-Lavallée lesion in the buttock region that was treated with limited incisional drainage and negative-pressure wound therapy, and also present a review of the literature.
