Evaluation of flow hemodynamics by color-Doppler following two different brachial arterial repair techniques.
OBJECTIVE
We compared the clinical and hemodynamic results following surgical repair of traumatic brachial artery injury using two different techniques micro- and macrovascular repair.


METHODS
This was a retrospective study of 27 patients who had sustained penetrating, clean cut injuries of the brachial artery. Macrovascular techniques and a saphenous vein graft was used in 13 patients, while 14 patients were treated by primary microsurgical technique. Postoperatively, patients were followed for a mean of 26 months. All patients had color Doppler examination of the brachial artery, digital artery pressures and transcutaneous oxygen saturation determined.


RESULTS
Clinical results based on distal pulses, Allens test and digital pressures were similar in the two groups. Color Doppler showed 8/13 anastomotic stenoses in macrovascular vein grafted repairs and 2/14 in microvascular repairs (p<0.05). The ratio of flow velocity proximal compared distal to the injury was significantly decreased in patients who had macrovascular repairs.


CONCLUSIONS
Using ratio between proximal and distal site of anastomosis maximal peak systolic velocity as a objective color Doppler parameter, we were able to demonstrate differences in the hemodynamic status following macrovascular repair with vein grafts and microvascular primary repair. The results emphasize the importance of using a standard repair technique for similar injuries rather than the preference of the surgeon.
