Percutaneous sinus angiography and three-dimensional CT imaging showing morphological and draining features of venous malformations in soft tissue

Imaging assessment and treatment of soft-tissue venous malformations: Retrospective case series study of 126 cases

Venous malformations (VMs) are common slow-flow vascular malformations, which affect almost anywhere of the body. From January 2010 to October 2019, 126 patients with VMs who had complete imaging and follow-up data were enrolled into this study, including 75 males. The initial treatment age ranged from 5 to 72 years. The role of imaging results on the choice of treatment measures and the application were summarized. In this study, we retrospectively analyzed the imaging examinations, treatment measures, and follow-up results of the patients with VMs in our clinic. In this series, imaging examinations included ultrasound, magnetic resonance imaging, computed tomography (CT) scan and enhanced scan, percutaneous sinus angiography and three-dimensional CT imaging, plain film, CT venography, CT angiography, and digital subtraction angiography. Treatment measures included surgical excision (n = 20), sclerotherapy (n = 86, including absolute ethanol [n = 75], polidocanol [n = 8], and pingyangmycin [n = 3]), and combination treatment with intralesional copper wire retention and sclerotherapy(n = 20). After treatment, most of the lesions shrunk obviously or disappeared, and the symptoms were largely relieved. Comprehensive and accurate imaging assessment of VMs is necessary for selecting appropriate treatment. Individual strategy and sequential treatment can achieve effective results and avoid potential complications.

The Efficacy of Absolute Ethanol and Polidocanol in the Treatment of Venous Malformations

INTRODUCTION

Using meta-analysis to evaluate the efficacy of absolute ethanol and polidocanol in the treatment of venous malformations.

MATERIALS AND METHODS

A systematic search of the English literature was conducted in April 2019 including PubMed, Embase and Web of Science. Article selection was based on preset criteria. The included literature was scored on the MINORS scale, and the meta-analysis and the forest plot were made using the R 3.5.1 software for efficiency.

RESULTS

Ten articles were included in the meta-analysis. Absolute ethanol response rate ranged between 79% and 92% with a pooled rate of 85%, and polidocanol response rate ranged between 63% and 94% with a pooled rate of 77%.

DISCUSSION

Although sclerotherapy is effective in most studies, a large number of randomized controlled trials are still needed to confirm the best treatment options at different sites.

Diagnosis and treatment of intermuscular venous malformations: A retrospective study in one center

OBJECTIVES

Intermuscular venous malformations are common vascular malformation, do not have typical symptoms, and are difficult to diagnose. This article is a retrospective analysis of the diagnostic and therapeutic measures of intermuscular venous malformations.

METHODS

From January 2013 to June 2018, 21 patients were included in this study. The clinical presentations, managements, and follow-up results were retrospectively analyzed. The indications and potential risks of different treatments were summarized.

RESULTS

The complaints of patients with intermuscular venous malformations included local pain, swelling, discomfort, or aggravation after activity. Ultrasound, phlebography, magnetic resonance imaging, percutaneous sinus angiography, and three-dimensional computed tomography imaging were performed. The patients received surgical excision, sclerotherapy, or the combinational therapy of intralesional copper wires retention and ethanol injection and were followed for six months to five years. All patients' symptoms were relieved largely. The lesions evaluated by magnetic resonance imaging decreased apparently or disappeared.

CONCLUSIONS

Imaging examinations are necessary in the diagnosis of intermuscular venous malformations and can guide the choice of treatment. Individualized treatment for intermuscular venous malformations should be made to achieve good effect and avoid adverse effects.
