Usefulness of preoperative stress perfusion imaging in predicting prognosis after liver transplantation.

摘要: The role of preoperative stress single-photon emission computed tomographic (SPECT) imaging in patients with end-stage liver disease who underwent transplantation is not well established. We reviewed medical records had at our institution between January 1998 and November 2001. During this time, 339 (213 men, aged 51 ± 11 years) transplantation. Of these, 87 SPECT imaging. Diabetes mellitus (30% vs 11%), hypertension (26% 12%), coronary artery (15% 7%) were more prevalent those than without (p <0.01 each). perfusion images normal 78 (91%) the left ventricular ejection fraction was 72 10%. revealed ascites 66% splenomegaly 83% patients. There 35 total deaths (10%) 5 nonfatal myocardial infarctions over a mean follow-up 21 13 months. Most (32 35) noncardiac sepsis most common cause death. A study 99% negative predictive value for perioperative cardiac events. Kaplan-Meier survival curves showed an 87% 2-year cumulative rate group. Thus, undergoing transplantation, depends on early identified very low risk late events despite higher profile. also unique findings, such as splenomegaly, which could produce image artifacts may interfere accurate interpretation.
