Microvascular Surgery
Microsurgical Flowprobes take the guesswork
out of knowing volume flow...
Transonic® Microsurgical Flowprobes
work with HT350 and HT360-Series
Flowmeters to measure volume flow in
0.5 - 4.0 mm blood vessels and grafts.
The non-constrictive Flowprobes use
gold standard transit time ultrasound
technology to measure volume blood
flow directly within these small blood
vessels.
“…TTFV (Transit-time Flow Volume) provides novel physiologic
flap data and identifies flow anastomoses and higher-flow venae
comitantes. These data have clinical value in microsurgery and hold
the potential to reduce microvascular complications and improve
outcomes.“
JC Selber, MD, MPH et al
The new line of microvascular
Flowprobes now offer the surgeon
a quantitative tool with which they
can objectively assess the quality of
the reconstruction or replantation.
Unseen blood flow obstructions can be
detected intraoperatively and repaired
before leaving the operating room.
“Accurate flow measurements can be of great assistance during vascular
reconstructive surgery. The primary aim with these intraoperative
measurements is to obtain information on the immediate result of the
reconstruction, where a technical failure may jeopardize an otherwise
successful operation.”
A Lundell, MD, FACS
No longer will a micro-vascular
surgeon have to rely solely on clinical
impressions to assess the quality of
the surgery during the procedure. This
on-the-spot volume flow technology
produces flow information quickly,
accurately, and non-intrusively.
The ability to immediately correct
otherwise undetectable flow
restrictions provides the surgeon with
a unique opportunity to improve their
patients’ outcomes.
“Including flow in my surgical approach gives me a high degree of
control over surgical outcomes. When I close the patient, I know the
patient will recover without ischemic surprises. This translates into
peace of mind for the patient and for me.”
F Charbel, MD, FACS
TRANSIT-TIME ULTRASOUND TECHNOLOGY
MEASURES VOLUME FLOW, NOT VELOCITY
Two transducers pass ultrasonic signals, alternately intersecting
the vessel in upstream and downstream directions. The difference
between the two transit times yields a measure of volume flow.

A Prospective Study of Transit Time Flow Volume
(TTFV) Measurement for Intraoperative Evaluation
and Optimization of Free Flaps
OBJECTIVE
To determine if transit-time volume flow measurements improve decision-making in microvascular free tissue
transfer procedures.
STUDY
Transit-time volume flow was measured in 52 consecutive free flaps (five types) by five surgeons. Thirty-eight
(73.1%) of the flaps were harvested to reconstruct head and neck defects, while the remaining 14 (26.9%) (all
TRAMs) were harvested for breast reconstruction. Flow measurements were performed:
• In Situ, after flap elevation and isolation on its pedicle;
• Immediately following anastomosis and reperfusion;
• Thirty minutes following anastomosis and reperfusion.
Intra-operative decisions based on transit-time volume flow measurements were documented.
RESULTS
•
•
•
•
Arterial inflow was, on average, 1.5 times greater than venous outflow, and arterial resistance was 3.59
times greater than venous resistance (arterial: 9.04 mL/min; venous: 7.24 mL/min)
Free transverse rectus abdominis musculocutaneous (TRAM) flaps had the highest arterial and venous
flows (14.2 mL/min; venous: 11.3 mL/min), and free radial forearm flaps (RFF) had the lowest (arterial: 6.33
mL/min; venous 5.29 mL/min).
Compared to the baseline (In Situ) measurement, all flaps had higher flows immediately after transfer
(Time 1) (p<0.0001), but no significant differences were seen 30 minutes later (Time 2) (p=0.68). Arterial
resistance, however, increased during that interval (p=0.006).
In more than a third of the cases (19 out of 52), operative decisions and when to revise an anastomosis,
were modified on the basis of transit-time volume flow findings.
CONCLUSION
“Transit-time volume flow measurements provide novel physiologic flap data and identify flawed anastomoses
and higher-flow venae comitantes. These data have clinical value in microsurgery and hold the potential to
reduce microvascular complications and improve outcomes.“
TAKE HOME POINTS
• This publication from a microvascular surgeon key opinion leader provides proof that volume flow
measurements can provide quantifiable measurements of one of the most critical pieces of microvascular
reconstruction: inflow and outflow.
• The author notes that perhaps the most compelling finding of the study is that flow measurements could
alter or augment surgical decision making as it had in 36% of the cases in the study. These quantitative
measurements “fill a knowledge gap” in microsurgery.

Publication Brief
Refining Perforator Selection for DIEP
Breast Reconstruction Using Transit-time
Flow Volume Measurements
OBJECTIVE
To examine the usefulness of transit-time ultrasound volume flow measurements in assessing perforator
vessels in deep inferior epigastric artery perforator (DIEP) flap harvesting and to evaluate their correlation
with computed tomographic angiography (CTA) and hand-held Doppler signals in identifying perforators.
STUDY
•
•
•
•
•
•
CTA was used to identify abdominal wall perforators for ten consecutive free DIEP breast
reconstructions in eight women (two with bilateral mastectomies, six with unilateral).
Abdominal wall perforating vessels >1 mm in diameter were evaluated intraoperatively with a
conventional hand-held 8-MHz Doppler and a transit-time ultrasound flowmeter.
The location of the vessels was correlated with preoperative CTA.
Information about arterial versus venous flow patterns and mean flow values were recorded for each
vessel typically, with a 2 mm flowprobe, but occasionally, with a 3 mm flowprobe. Flow values were
correlated with both CTA and hand-held Doppler signals.
Information about arterial versus venous flow patterns and mean flow values were recorded for each
perforator.
Perforators with high volume flows and an arterial waveform were selected to supply the flap.
RESULTS
•
•
•
•
Of the 54 eligible perforators identified, transit-time flow measurements showed arterial flow
waveforms in 15 of 16 perforators identified by CTA and in 2 of the remaining 38 vessels.
Mean flow for the 16 arterial vessels was 5.3 mL/min. Mean flows for the remaining 38 dissected vessels
was 2.1 mL/min.
Transit-time flow measurement sensitivity in identifying arterial perforators was 94%; specificity was
95%.
Hand-held Doppler was misleading in 70% of vessels.
CONCLUSION
•
•
•
Transit-time flow measurements distinguished arterial from venous waveforms in vessels that appear
arterial by hand-held Doppler signals.
CTA and transit-time flow measurements had high correlation.
The use of transit-time flow measurements may prevent poor perfusion seen in some DIEP flaps.
DISCUSSION
This group from the University of Toronto tested the use of transit-time ultrasound flowmetry to identify
optimal deep inferior epigastric arterial perforators to harvest for breast reconstruction. Moreover, they
suggest that transit-time flowmetry may be able to predict early patency in completed microvascular
anastomoses, as is the case in CABG surgery.
