Background-Routine coagulation tests do not necessarily reflect haemos
tasis in vivo in cirrhotic patients, particularly those who have bleed
ing varices. Thrombelastography (TEG) can provide a global assessment
of haemostatic function from initial clot formation to clot dissolutio
n. Aim-To evaluate TEG changes in cirrhotic patients with variceal ble
eding and their association with early rebleeding. Patients/Methods-Tw
enty cirrhotic patients with active variceal bleeding had serial TEG a
nd routine coagulation tests daily for seven days. The TEG variables b
efore the day of rebleeding (n = 6) were compared with those of patien
ts without rebleeding (n = 14). Results-Baseline characteristics reble
eding and non-rebleeding groups were comparable apart from a higher in
cidence of uncontrolled infection on the day of rebleeding in the rebl
eeding group (p = 0.007). The patients in the rebleeding group were mo
re hypocoagulable before the day of rebleeding as shown by longer r (4
2 v 24 mm, p<0.001) and k (48 v 13 mm, p<0.001) and smaller a (12 v 38
degrees, p<0.001) compared with the mean of daily results of the non-
rebleeding group. Routine coagulation tests, however, showed no signif
icant differences between the two groups. Conclusion-The results of se
rial TEG measurements suggest that hypocoagulability may be associated
with early rebleeding in cirrhotic patients.
