In addition, endovascular technologies including embolization are not suitable in these cases because of dispersed and extensive lesions of severe venous vascular malformation, which are different from common vascular malformations.
In summary, the current treatments for patients with multiple severe venous vascular malformation syndrome combined with coagulopathy involve symptomatic and conservative therapies which focus on the quality of life of the patients during treatment and the prevention of serious complications.
The diagnosis and the classification of the vascular malformations have a great importance on the treatment plan of the lesions.

Based on their biological and clinical behaviour, vascular anomalies can be broadly divided into two groups: vascular tumours and vascular malformations.
Vascular malformations are congenital lesions of vascular dysmorphogenesis, are always present at birth, and enlarge in proportion to the growth of the child.
Vascular tumours have increased endothelial cell turnover while vascular malformations do not.
There were two major categories of lesions that emerged from this review which included vascular tumours like haemangiomas (26 cases) and vascular malformations (26 cases) [2].
Because its clinical signs and symptoms are nonspecific, IPEH, like most other vascular malformations, poses a difficult diagnostic challenge.
33] MRI is usually superior as the initial diagnostic test for vascular malformations, and further investigations are usually not necessary in low-flow lesions.
