Abstract
Radial artery pseudoaneurysm is a rare complication of transradial catheterization. We report a 74-year-old woman on rivaroxaban who developed a pulsatile distal forearm mass 1 day after transradial cardiac catheterization. High-frequency ultrasound showed a rounded extra-arterial lesion (7.6 × 8.9 × 7.0 mm) not involving all wall layers, with thrombus, a discrete communicating neck, turbulent bidirectional "yin-yang" color Doppler, and preserved distal flow. Anatomic mapping showed the lesion abutting adjacent tendons and the palmar cutaneous branch of the median nerve. Surgical excision and microscopic repair succeeded. Sonographic characterization provided anatomic detail that, with clinical and surgical assessment, informed individualized management.
期刊介绍：
The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography.
The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents.
JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
