STUDY DESIGN A radiographic and morphologic study was conducted to investigate low-grade spondylolisthesis in cases with preexisting isthmic spondylolysis of L5. OBJECTIVE To distinguish radiographically between vertebral slips before and after skeletal maturity as determined by deformities of the sacral endplate. SUMMARY AND BACKGROUND DATA Very few(More)
Carbon dioxide (CO2) intraarterial digital subtraction angiography (IADSA) provides retrograde visualization of the portal vein via a peripheral segmental hepatic artery. IADSA was performed in 12 patients with known hepatic diseases by injecting a peripheral hepatic artery with both CO2 gas and an iodinated contrast medium. The portal vein was constantly(More)
Five femoral pseudoaneurysms were treated among 573 patients who underwent percutaneous coronary interventions. Four of the five patients suffered from diabetes mellitus and four patients needed regular hemodialysis due to chronic renal failure. One patient's course was complicated by infection. One patient was healed by compression therapy and four(More)
Retroperitoneal tumors and other abdominal malignancies invading the inferior vena cava can be treated surgically when no metastases are present. We resected four retroperitoneal tumors, two renal cell carcinomas, and one gastrointestinal stromal tumor with a concomitant caval resection. Although meticulous care is required when manipulating the major(More)
OBJECTIVES We have assessed clinically systemic tissue oxygenation by monitoring mixed venous oxygen saturation (SvO2) in addition to hematocrit (Hct) during cardiopulmonary bypass. Based on results of experimental studies together with clinical experience, we previously defined the lower limits of the critical range as an Hct of 12% and an SvO2 of 46%.(More)
Atrial fibrillation (AF) is one of the most common complications following cardiac surgery. AF is associated with an increased risk of stroke, prolonged hospitalization and increased medical costs. Risk factors of post-operative AF are valvular surgery, advanced age, and pre-operative history of AF. Postoperative AF occurs most frequently at 2 days after(More)
Background: To evaluate the findings of altered flow dynamics in the livers of patients with obstruction of superior vena cava (SVC) on helical computed tomography (CT). Methods: In six patients (age range = 28–80 years) with SVC obstruction, CT findings were retrospectively reviewed to identify the abnormal enhancement patterns of the liver and the(More)
