ABSTRACT
OBJECTIVE:
To systematically assess available information about all variations of obturator vessels and to present the most surgically relevant types, their prevalence and calibre in order to provide a comprehensive overview for both anatomists and clinicians. MATERIALS ANDMETHODS:
A total of 2689 studies were found via searching the online databases. After applying exclusion criteria 44 studies were assessed. The cadaveric studies, CT angiographies, and clinical studies were included. Number of hemipelves, prevalence of each variation and calibre of identified vessels were studied. Each variation was classified as aberrant obturator artery/vein, aberrant accessory obturator artery/vein or anastomosis.RESULTS:
In included studies the average incidence of the variant obturator artery was 26% with the aberrant obturator artery being the most frequent type (with the mean calibre 2.10â¯mm, SD = 0.35â¯mm), while the overall incidence of the variant obturator vein was 55%. Presented venous structures had the mean calibre of 2.98â¯mm (SD = 0.56â¯mm).CONCLUSIONS:
According to reviewed studies, variant obturator vessels are present in a great number of patients. Due to their possible calibre larger than 3â¯mm they represent a structure of high clinical importance. It is important to unify the terminology and to stress out the significance to all clinicians.Key words
