During the thrombectomy of a thrombosed PTFE loop AV graft in the right upper arm, what was the estimated blood loss?

The main concept here is estimating blood loss during a controlled vascular thrombectomy with proximal and distal control of a thrombosed graft. When a PTFE loop AV graft is thrombosed, the surgeon clamps the ends to isolate the segment, then removes the thrombus with careful suction and irrigation. Because the field is controlled and most of the work is within the graft lumen or the immediate graft area, substantial arterial bleeding is minimized. The bleeding you can expect in a straightforward thrombectomy under good control is typically quite small, on the order of a few tens of milliliters. Around fifty milliliters fits that scenario: enough to account for some oozing and irrigation but not large-volume blood loss. Significantly higher volumes, such as 100, 200, or 500 mL, would suggest additional bleeding sources or complications (for example, more extensive venous ooze, graft rupture, or difficulties maintaining hemostasis). This is why fifty milliliters is the best fit for this situation.
