Porter’s Portal

Adrian’s dream job after college was to become a Wall Street stockbroker. He went about pursuing this ambition by taking a job at the Waldorf-Astoria as a porter hoping to make contacts with hotel guests who’ve already succeeded in his chosen field as he takes their luggage to their rooms.  Sure enough he does. A principal at the city’s premier brokerage firm is a frequent guest who eventually invites our wannabe stockbroker Adrian to travel with him to Brazil’s Amazon Forest while serving as the expedition’s porter. On the trip, Adrian gains valuable insight into becoming an accomplished stock picker. Adrian also picks up a schistosomiasis infection that is unrecognized by his physicians. In time, he develops portal hypertension, impeding the drainage of the portal vein. In the image, where does the outflow of the indicated vein lead to?
