Abstract:
The objective was to prepare guidelines to perform the current optimum treatment by organizing effective and efficient treatments of hemangiomas and vascular malformations, confirming the safety, and systematizing treatment, employing evidence-based medicine techniques and aimed at improvement of the outcomes. Clinical questions (CQs) were decided based on the important clinical issues. For document retrieval, key words for literature searches were set for each CQ and literature published from 1980 to the end of December 2020 was searched in PubMed, and Japana Centra Revuo Medicina (JCRM). The strengths of evidence and recommendations acquired by systematic reviews were determined following the Medical Information Network Distribution Service (Minds) technique. A total of 38 CQs were used to compile recommendations and the subjects included efficacy of resection, sclerotherapy/embolization, drug therapy, laser therapy, radiotherapy, and other conservative treatment, differences in appropriate treatment due to the location of lesions and among symptoms, appropriate timing of treatment and tests, pathological diagnosis deciding the diagnosis, and causal genes of vascular anomalies. Thus, the Japanese Clinical Practice Guidelines for Vascular Tumors, Vascular Malformations, Lymphatic Malformations, and Lymphangiomatosis 2022 have been prepared as the evidence-based guidelines for the management of vascular anomalies.
Insights
These guidelines provide evidence-based recommendations for treating vascular tumors and malformations. They cover various treatments like surgery, sclerotherapy, and drug therapy to improve patient outcomes.
Area of Science:
- Vascular Surgery
- Dermatology
- Pediatric Oncology
Background:
- Hemangiomas and vascular malformations require standardized treatment protocols.
- Current management strategies vary, necessitating evidence-based guidelines.
Purpose of the Study:
- To develop comprehensive, evidence-based clinical practice guidelines for managing vascular tumors and malformations.
- To optimize treatment efficacy, safety, and outcomes using systematic review methods.
Main Methods:
- Formulated clinical questions based on critical clinical issues.
- Conducted systematic literature searches (1980-2020) in PubMed and JCRM.
- Evaluated evidence strength and recommendations using the Minds technique.
Main Results:
- 38 clinical questions addressed a range of treatments including resection, sclerotherapy, embolization, drug therapy, laser, and radiotherapy.
- Guidelines consider lesion location, symptoms, timing of intervention, diagnosis, and genetic factors.
- Recommendations cover hemangiomas, vascular malformations, lymphatic malformations, and lymphangiomatosis.
Conclusions:
- The Japanese Clinical Practice Guidelines for Vascular Tumors, Vascular Malformations, Lymphatic Malformations, and Lymphangiomatosis 2022 offer a systematic approach.
- These guidelines aim to standardize and improve the management of diverse vascular anomalies.

The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
