Anatomical patterns of pelvic venous reflux to the lower limbs.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPelvic venous insufficiency is an important but frequently overlooked cause of lower limb varicose veins and early recurrence after superficial venous interventions. Understanding the reflux patterns and distribution of lower limb varicose veins with pelvic origin is crucial for preventing recurrence and unsatisfactory outcomes, which may result from incomplete or inadequate investigation.
methodsData from 49 female patients (62 limbs) with pelvic reflux that connects to the lower limbs through pelvic escape points were analyzed. All patients were examined for reflux in the standing position using duplex ultrasound examination. Special attention was given to the reflux patterns, distribution, and connections to the saphenous veins, nerves, and lymph nodes.
resultsMost patients were classified as CEAP C2 (95%), and 70% reported leg pain. The most frequently observed patterns were varicose veins on the posterior surface of the thigh (19%), veins connected to the great saphenous vein (GSV) along the thigh and leg (29%), and veins running parallel to the GSV on the medial thigh (26%). Varicose veins confined exclusively to the perineal region were identified in 15% of patients. Less common patterns included varicose veins on the anterior thigh (8%), veins associated with the sciatic nerve (10%), and veins with lymph node connections (8%). Varicose veins connected to the small saphenous vein were the least frequent, accounting for 5% of cases.
conclusionsAlthough the GSV is often involved in patients with pelvic venous insufficiency and escape points, nonsaphenous varices appear to play a more prominent role in the reflux pattern. These findings support the concept that pelvic-origin reflux manifests as distinct patterns of lower limb varicose veins through defined pelvic escape points, underscoring the importance of thoroughly assessing the connection between pelvic and lower limb venous territories. A better understanding of the distribution of nonsaphenous reflux during venous mapping is essential for optimizing treatment strategies and reducing the risk of recurrence.
