Objective: Doppler ultrasound and digital plethysmography are used at our institution to determine the suitability of the radial artery for harvest prior to coronary artery bypass grafting (CABG). The purpose of this study is to determine the value of this preoperative evaluation. Methods: A retrospective analysis of non-invasive radial artery testing was performed on 187 CABG patients. Criteri...

BACKGROUND The purpose of the study was to assess blood flow in the upper limb arteries after prolonged catheterization with long radial artery catheters (LRC) which reach the subclavian artery compared to catheterization with standard short radial artery catheters (SRC) and a group of upper limb flow without any catheter placement (NOCATH), with both SRC and NOCATH as control groups. METHODS...

OBJECTIVE To investigate the involvement of arteries other than the temporal arteries in active giant cell arteritis using color Doppler sonography. METHODS The occipital, facial, vertebral, carotid, subclavian, axillary, brachial, ulnar radial, femoral, popliteal, posterior tibial, and dorsal pedal arteries, and the abdominal aorta of 33 consecutive patients with acute giant cell arteritis a...

A rare case of pediatric brachial plexus laceration is presented. A five-year-old boy who sustained a sharp laceration on his right axillary region was immediately operated. The axillary artery, radial, ulnar and musculocutaneous nerve branches of the brachial plexus, and the lateral root of the median nerve were totally lacerated. The medial root of the median nerve was partially transected. A...

The boundaries of the space through which the ulnar neurovascular bundle crosses the wrist have been reinvestigated. Using gross dissections, transverse and sagittal sections, and histologic study, we determined that the roof of Guyon's canal, the "carpal ulnar neurovascular space," does not directly connect to the hamate bone, as is currently accepted. The roof of this space extends radially t...
