A rare anatomical variation of the deep femoral vein with aneurysm: a case report with clinical significance.
Article in Anatomy & cell biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
We present a rare anatomical variation of the deep femoral vein (DFV) originating from the popliteal vein (PV) with an associated aneurysm. The DFV arose from the PV at the adductor hiatus, exhibited an aneurysm, and coursed upward through the fourth osseo-aponeurotic opening of the adductor magnus muscle to enter the anterior thigh compartment before draining into the femoral vein. This unique variation likely resulted from developmental deviations during intrauterine life. The anomalous origin and aneurysm of the DFV may potentially cause venous hemodynamic disturbances, chronic venous insufficiency, increased risk of deep vein thrombosis, and potentially life-threatening pulmonary embolism. Anatomical variations of the DFV in terms of origin, course, or termination are rare but clinically relevant, especially in the context of vascular surgeries, imaging, and interventional procedures involving the femoral region. This case highlights the importance of recognizing venous anatomical variations and their clinical implications.
