Karna had several sons and the names of nine of his sons are mentioned. Of the nine, only one survived the Kurukshetra war. Vrasasena; Sudhama; Shatrunjaya; Dvipata; Sushena; Satyasea; Chitrasena; Susharma(Banasena); and Vrishakethu
Vrishakethu was the only son of Karna that survived the horrific slaughter called Kurukshetra war. He later came under the patronage of the Pandavas. During the campaign that preceded the Ashvamedha –yaga, Vrishakethu accompanied Arjuna and participated in the battles with Sudhava and Babruvahana. During that campaign Vrishakethu married the daughter of king Yavanatha (perhaps a king of the western regions). It is said, Arjuna developed great affection for Vrishakethu, his nephew.
