Recognition of aberrant vasculature to the liver before PD is important. Preoperative imaging studies will often be adequate to identify these anomalies, but interpreting radiologists may not be aware of its clinical significance. Surgeons performing PD must be adept at managing ARHAA safely.

Cysts with HR, previously proven to represent corpus luteal cysts, can be readily seen on contrast-enhanced CT studies in women of reproductive age. Familiarity of the varied CT appearance of these cysts is essential, lest they be misinterpreted as pathological entities.

Increasingly, endovenous ablation of the greater saphenous vein (GSV) is used for the treatment of symptomatic varicose veins. The propagation of thrombus can result in a “tail of thrombus” within the common femoral vein (CFV). In two cases, patients were treated with low molecular weight heparin and re-imaged within 1 week. In both cases, complete resolution of the thrombus was confirmed, and anticoagulation was discontinued. Thrombus extension into the CFV after endovenous ablation may be safely treated with short-term anticoagulation and followed by duplex ultrasound. If unresolved, standard deep vein thrombosis anticoagulation is indicated.
