( CNN ) -- King Abdullah of Saudi Arabia has left a New York hospital to recuperate at his home in the city , the official Saudi Press Agency said Wednesday . The king left the New York Presbyterian Hospital / Weill Cornell Medical Center Tuesday night , the news agency said citing the Royal Court . The statement did not say how long Abdullah will remain in New York . Abdullah first underwent successful surgery on November 24 . He had a successful follow-up back surgery on December 3 to stabilize several vertebrae in his spine , the agency said earlier . The king traveled to the United States for treatment of a herniated spinal disc and a blood clot that was causing him back pain , Saudi state media reported . Abdullah , 86 , had named Crown Prince Sultan to administer the state 's affairs in the monarch 's absence , the state-run Saudi Press Agency reported at the time . The top three figures in the kingdom -- Abdullah , Sultan and Prince Nayef , the country 's interior minister and second deputy prime minister -- are all sons of King Abdul Aziz Ibn Saud , who founded modern Saudi Arabia in 1932 . Abdullah has ruled the oil-rich kingdom since the August 2005 death of his half-brother , King Fahd . But Abdullah ran most of the kingdom 's affairs for a decade before that on behalf of his ailing half-brother . Since coming to power , he has sought to establish rules and procedures for many Saudi institutions , giving him a reputation as a reformer in the highly conservative nation .
It is not known how long King Abdullah will remain in New York . He undergoes two successful surgeries .
