Internal venous anomalies in patients with a genital venous malformation

Abstract

Background

Cutaneous venous malformation (VM) can be associated with internal vascular anomalies. Our objective was to investigate the frequency of internal vascular anomalies in patients with an isolated genital venous malformation to assess the utility of screening for internal findings.

Methods

We retrospectively reviewed our Vascular Anomalies Center database for patients with a focal genital venous malformation presenting between 1999 and 2016. Abdominal and pelvic imaging reports were reviewed for internal vascular anomalies. Endoscopy reports were also reviewed when available.

Results

A focal genital venous malformation was found in 22 patients (14 female, 8 male). Ten (45%) had a venous malformation of at least one internal structure, most commonly the pelvic floor (n = 6), colon (n = 5), urethra (n = 4), and/or bladder (n = 3). Eight experienced hematuria, hematochezia, and/or rectorrhagia secondary to their internal venous malformation. In patients with internal venous malformations, the mean age of symptom presentation was 7.3 years (range 1-22 years). Two patients had malformed inferior mesenteric and portal veins visible using ultrasonography and magnetic resonance imaging. They required surgical intervention to prevent thrombosis and decrease urogenital and gastrointestinal bleeding.

Conclusion

Nearly half of our patients with a focal genital venous malformation had internal venous anomalies. Physicians should suspect urogenital or gastrointestinal venous malformations in patients with a focal genital venous malformation, especially if they develop hematuria, hematochezia, or rectorrhagia. Significant mesenteric venous trunk anomalies can also occur. Because these require surgical intervention, early recognition is important. We recommend that all patients with a focal genital venous malformation undergo abdominal and pelvic ultrasound to evaluate for internal venous anomalies.
