Rare anomalous origin of superior left pulmonary artery from left subclavian vein.

We report for the first time an extremely rare anomalous origin of the superior left pulmonary artery in a 60 year-old man. Although it was occult in clinical indications, such a malformation still ought to be considered, especially during endovascular procedures.

[In vivo fluorescent microscopy of the liver microcirculation after embolization with a newly developed trans-proper hepatic arterial infusion animal model].

Objective: To evaluate the value of the in vivo fluorescent microscopy in studying the changes of liver microcirculation after embolization with a newly developed animal model for tans-proper hepatic arterial infusion, and to summarize the method of making this animal model.

Methods: Ten Sprague-Dawley rats were used in this study. After a midline abdominal incision, microcatheter was placed into the gastroduodenal artery (GDA).
