This study reported a case of a 12-year-old girl from Laos with a leg and labial arteriovenous malformation accompanied by a wound on the right ischial ulcer, which impacted her physical and psychological health. She sought medical attention via a "Trans-national" or cross- national" service from October 31, 2019, to January 31, 2020. The author assessed the client using Gordon's 11 health functions evaluation tool. Data were collected through observation, interviews, and physical examination. The chief problems were identified, which included the integrity of impaired tissues, acute pain, and body image disturbance. During hospitalization, the medical team achieved two-way communication through translators, graphics cards and network translation, then the child underwent right labia vascular embolization and right labia lump resection. After successful surgery, the lump between the legs disappeared, and wound debridement was performed along with ion dressing care. The wound healed gradually and pain was eased. We wish to share this experience of a rare case in international medical care.
