The possibility that venous blood could be withdrawn through a radial artery cannula when venous pressure is high was examined in 30 patients during cardiopulmonary bypass for coronary artery bypass operation. Progressive desaturation of radial artery blood occurred when venous pressure was equal to arterial pressure. Desaturation not only increased with duration of venous obstruction but also ...

We present a case of osteonecrosis of femoral head (ONFH) that occurred after stent angiography of femoral artery for the treatment of arteriosclerosis obliterans (ASO) of left inferior limb in a 76-year-old woman. No case of late collapse of femoral head as a complication of endovascular procedure such as stent placement has been previously documented. We considered that ONFH occurred after de...

Correspondence Rare origin of the inferior epigastric artery from an anomalous medial circumflex femoral artery Mathes & Bostwick (1977) surgically manipulated the rectus abdominis myocutaneous flap to repair defects in the anterior abdominal wall. Subsequently this flap was used in breast reconstruction (Robbins, 1981 ; Hartrampf et al. 1982) as a donor for free-tissue transfer (Bunkis et al. ...

Popliteal artery aneurysms are often incorrectly diagnosed and subsequently mismanaged with resultant preventable complications. We present a case of a swollen lower extremity clinically resembling a deep vein thrombosis (DVT), following tibial fracture fixation. It was treated as a DVT on the basis of ultrasound imaging at a different hospital. Subsequent imaging showed a popliteal artery pseu...

We present a case of a 34-year-old male who presented to the emergency ward with fever and abdominal pain. The diagnosis of Takayasu's arteritis and also antiphospholipid syndrome was made during an imaging workup of deep-vein thrombosis. A spontaneous coronary artery dissection was revealed in coronary CT angiography requested for chest pain and dyspnea. The patient was treated medically and d...
