Two patients with congestive heart failure underwent successful closure of patent ductus arteriosus (PDA) at ages 58 and 63, respectively, using the transfemoral technique of Porstmann and Sato. The long-term benefits obtained in these two patients suggests a potential role for this technique in the elderly patient with PDA

During the past ten years, 180 patients with liver cirrhosis and hematologic disorders underwent splenectomy and distal splenorenal shunts, 56 of whom were evaluated by CT, ultrasonography (US) and/or angiography, postoperatively at Hiroshima University Hospital and Hiroshima Red Cross Hospital. Five patients were asymptomatic; thrombosis was observed in 10; and two died of liver failure. Three patients each complained of postprandial epigastralgia with diarrhea, fever, and general malaise. Angiography was performed to evaluate the patency of the shuts; CT and US, to follow up the liver cirrhosis not the portal vein thrombosis. Since thrombosis of the portal venous system occurs frequently during surgery, and since it causes marked changes in portal vein hemodynamics, the portal and superior mesenteric veins must be observed by US and CT for the early postoperative detection and treatment, to avoid major surgery.

びまん性肝疾患におけるdynamic CTの診断的有用性を検討する目的で,32例の肝硬変,23例の慢性活動性肝炎(CAH), 15例の正常例に対し本法を実施した.各症例の肝右葉から得られたtime-density curveを数量的に評価するためgamma variatefit techniqueを用い,fitting equationの2つの係数(α,β)から導びかれた3つのparameterすなわちrise time (RT), decay time (DT), corrected first moment (MC)を比較することによりcurveの変化を分析した.3つのparameterは疾患の重症度に伴い増加し,これは障害された肝のcurveでpeakが遅れ,下降部分の傾きが緩徐化し,curveが遅延することを反映したものであった.MCは疾患の程度と最良の相関を示し,MC>95の33例中30例が肝硬変,95≧MC>70の21例中19例がCAH,70≧MCの16例中15例が正常であった.以上よりgamma variate fitによるdynamic CT time-density studyはびまん性肝疾患の鑑別診断に有用であることが結論された.
