Article Synopsis
  • - This study aimed to evaluate the natural progression of venous malformation (VM) and Klippel-Trenaunay Syndrome (KTS) over a 6-month period by observing changes in lesion volume and other health factors in 34 patients.
  • - The results showed no significant overall change in lesion volume or other health metrics such as pain, quality of life, and coagulation markers, but some patients had notable changes linked to local infections.
  • - Findings suggest that conducting a Phase 2 study to test new treatments without a placebo is justified, using this data as a standard for comparison.

Endovascular therapy is an important method of treating high-flow arteriovenous malformations (AVMs). The nidus of AVMs can be treated by transarterial or percutaneous approaches with the use of ethanol as a strong embolic agent; however, treatment outcomes are not always satisfactory and complications including skin necrosis often occur, particularly following the treatment of superficial lesions. Herein, we describe successful transvenous sclerotherapy of high-flow AVMs in the finger of a 47-year-old female patient that were causing erythema and spontaneous pain using ethanolamine oleate (EO) as a safe sclerosant.

Calciphylaxis is characterized by extremely painful skin ulcers and develops in patients with or without severe kidney diseases. Herein, a female patient without renal dysfunction developed calciphylaxis in the right lower extremity and underwent successful surgical debridement and split-thickness skin grafting. Nevertheless, prompt wound evaluation and proper surgical approaches are essential.

There has been a long-standing need for guidelines on the diagnosis and treatment of keloids and hypertrophic scars that are based on an understanding of the pathomechanisms that underlie these skin fibrotic diseases. This is particularly true for clinicians who deal with Asian and African patients because these ethnicities are highly prone to these diseases. By contrast, Caucasians are less likely to develop keloids and hypertrophic scars, and if they do, the scars tend not to be severe.

Background: We experienced the occurrence of breast deformity in some young female patients who underwent a modified Nuss procedure before breast development. We studied the causes of and preventive measures for this complication.

Methods: We classified 13 prepubescent female patients who underwent our modified Nuss procedure into three groups according to the direction of the skin incision and the dissection layer for bar insertion.

Vascular malformations of bone are complex lesions that can cause deformity and pain. A combined soft tissue and intraosseous venous malformation of the left thumb in a girl was treated with two sessions of ethanol sclerotherapy using a bone marrow aspiration needle under fluoroscopic guidance.

Background: It has recently been demonstrated that near-infrared (NIR) fluorescence imaging can be used to visualize the blood vasculature. Although sclerotherapy has been successfully used in treating venous malformations, the spread of sclerosant is difficult to monitor during sclerotherapy.

Objective: To evaluate the safety and efficacy of NIR fluorescence imaging in percutaneous sclerotherapy of soft-tissue venous malformations.

Background: Sclerosants are used to treat vascular malformations. Owing to variations in the flow, the injected concentrations and the duration of exposure of these sclerosants are altered. Therefore, the clinical effectiveness of sclerotherapy is variable.
