Walser [13] described and illustrated a case, in which a "port catheter was negotiated into the superior vena cava by way of a large, crossed-cervical venous collateral", but without exact anatomical description of the veins and illustrating a catheter with probably just a subcutaneous "cross-cervical" route and then passing through a large mediastinal vein. Even intercostal veins may serve as transcollateral venous access for port placement; however, this procedure requires a thoracotomy [14].
