Soft-tissue vascular malformations and tumors. Part 2: low-flow lesions.

Area of Science:

• Vascular Surgery
• Radiology
• Pathology

Background:

• Vascular anomalies encompass diverse lesions with unclear nomenclature and histopathology.
• Accurate classification and understanding of clinical/imaging features are vital for patient care.

Purpose of the Study:

• To review the classification of vascular anomalies.
• To describe the role of imaging in diagnosing vascular anomalies.
• To summarize features and discuss treatment options for low-flow vascular anomalies.

Main Methods:

• Literature review of current classification systems for vascular anomalies.
• Analysis of diagnostic imaging modalities for low-flow lesions.
• Synthesis of histopathologic, clinical, and imaging characteristics.

Main Results:

• This article focuses on low-flow vascular anomalies, differentiating them from high-flow lesions discussed previously.
• Key diagnostic features and treatment strategies for various low-flow malformations are presented.
• Complex syndromes associated with low-flow malformations are also addressed.

Conclusions:

• A clear understanding of low-flow vascular anomalies is essential for accurate diagnosis and effective management.
• Imaging plays a critical role in characterizing these lesions.
• This review provides a comprehensive guide to low-flow vascular anomalies and associated syndromes.
