Measuring the pressure in the superficial inferior epigastric vein to monitor for venous congestion in deep inferior epigastric artery perforator breast reconstructions: a pilot study
Research article published in Journal of reconstructive microsurgery (2010)
Abstract
During deep inferior epigastric artery perforator (DIEP) flap dissection, we noted that in many cases the superficial vein on the ipsilateral side of the flap was engorged and tense, and in others, it was empty. This led us to believe that the pressure is increased as the result of preferential outflow through the superficial vein in some cases, which could result in venous congestion of the flap if this vessel was not anastomosed. To test this hypothesis, we measured the venous pressure in the superficial venous system before and after flap dissection. The pressure in the superficial inferior epigastic vein of a DIEP flap was measured in 26 consecutive flaps to investigate the correlation between the pressure and venous congestion of the flap. The first measurement was performed at the beginning of the dissection, and the second measurement was taken after the flap had been completely raised on a single perforator. The mean increase in pressure after flap dissection was 10.6 mm Hg (mu = 10.6; range -1 to 31; O +/- 7.0 mm Hg). Clinical signs of venous congestion were observed in one case. In this case, the increase in venous pressure was with 31 mm Hg, also the highest. Although the results of this report are preliminary, they indicate that the pressure in the superficial vein of DIEP flaps might be of predictive value for venous congestion.

Why This Matters for Hirudotherapy
This pilot study measured venous pressure in the superficial inferior epigastric vein of 26 consecutive DIEP free flaps for breast reconstruction, finding a mean pressure rise of 10.6 mm Hg after flap dissection and noting that the single case of clinical venous congestion coincided with the highest recorded rise (31 mm Hg); the authors suggest superficial-vein pressure may have predictive value for congestion. For hirudotherapy this is relevant context rather than direct evidence: venous congestion of flaps is precisely the complication for which medicinal leeches are most often deployed as a salvage adjunct, so work on predicting congestion bears on when leech therapy might be anticipated or pre-empted. The honest caveat is that this is an explicitly preliminary pilot in a small consecutive series, it studies pressure monitoring rather than any leech intervention, and it makes no claim about treatment.
