Background:
The marginal vein (MV) is a congenital, predominantly venous vascular malformation, which is based on a lack of regression of the embryonic venous system in the lower extremities and is associated with a variety of complications. So far, no uniform treatment regimens have been described in the literature.
Objective:
What are the treatment strategies and outcomes in patients with a MV?
Material And Methods:
In the period from 1 January 2008 to 31 December 2020, all patients treated at the University Hospital Augsburg with MV were retrospectively reviewed.
Results:
The median age at the time of diagnosis was 14.8 years (3-42 years). Out of 16 patients 12 had a leg length difference, 75% of patients (12/16) already had chronic venous insufficiency (CVI) at the time of diagnosis of MV. Open surgical removal of MV was performed as first-line treatment in 31.3% (5/16) patients. The MV was primarily closed by endovenous laser therapy (EVLT) in 1/16 patients, 15/16 patients were treated with redo procedures and 2.6 ± 2.4 (mean±SD) redo procedures were performed per patient in follow-up. The mean follow-up was 8.1 years.
Discussion:
In order to prevent/avoid progression of CVI and thrombosis prophylaxis, the MV should be closed/removed promptly after diagnosis. The use of conventional surgical techniques for the removal of MV seems to have an advantage over treatment with minimally invasive procedures in terms of the number of secondary interventions required.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
