Arterial Inflow (arterial + inflow)
Selected AbstractsLeft Internal Mammary Artery (LIMA) Flow Reserve in Ischemic Hypertrophied HeartsJOURNAL OF CARDIAC SURGERY, Issue 1 2009Tomas A. Salerno M.D. We, herein, present clinical evidence suggesting that in ischemic hypertrophied hearts, single arterial inflow from the LIMA to multiple grafts based on the LIMA may not be sufficient and may not meet myocardial demands, at least during the early perioperative period. This observation was made in two patients in whom a vein graft, previously based on the LIMA, was also connected to the aorta. By providing additional inflow from the aorta, flows to the LAD significantly increased. [source] Combined cuff and suture technique for orthotopic whole intestinal transplantation in ratsMICROSURGERY, Issue 3 2002Atsunori Nakao M.D. For the purpose of immunological study on small intestinal transplantation (SIT), rat SIT models using direct suture technique widely have been used, which requires at least several months of training for microsurgery. Alternatively, a simple cuff technique for SIT has been mainly used by us, which reduces warm-ischemic time and the training period, but the entire intestinal grafts usually obtain a limited blood supply. This report describes a modification of a combined cuff and suture technique for rat SIT to aid beginning microsurgical transplantation researchers. The advantages are 1) use of only arterial suturing, making it easier for beginners, with the cuff technique applied to the more difficult vein anastomosis; 2) achievement of better arterial inflow and graft survival than when the arterial cuff technique is used; and 3) doing only partial clamping of the aorta, which improves animal survival and success of the procedure. A very high successful rate in orthotopic whole SIT was achieved even by beginners. © 2002 Wiley-Liss, Inc.

Tso Simultaneous pancreas-kidney transplantation has gained acceptance as a therapeutic modality for patients with end-stage renal disease secondary to diabetes mellitus. In some instances, performing the procedure as conventionally described with renal revascularization from the left iliac vessels and pancreatic arterial inflow from the right iliac vessels may be difficult or undesirable. We describe our experience with an alternate operative technique utilizing a single arterial conduit to vascularize both organs. We believe that this technique may be of use in certain patients undergoing simultaneous pancreas-kidney transplantation. [source] Extracting arterial flow waveforms from pulse oximeter waveformsANAESTHESIA, Issue 6 2001apparatus A method is described which allows an approximation to the arterial flow waveform to be derived from a pulse oximeter waveform. The observed pulse oximeter waveform is the sum of arterial inflow and venous outflow. These components are separated mathematically. Subtraction of the venous outflow reveals the underlying arterial flow waveform. The assumptions on which the method is based are stated explicitly and discussed. [source] | ||||||||||
