Background: To evaluate the technical results of the arterial repair, a variety of intraoperative imaging and assessment techniques can be used during carotid endarterectomy. The aim of the study was to evaluate the usefulness of intraoperative ultrasound flow measurement as a quality control after primary carotid endarterectomy in the setting of a teaching hospital. Methods: One hundred and seven consecutive carotid endarterectomies were performed over 24 months at our institution. Retrospectively acquired demographics, intraoperative flow measurements, duplex results, revisions, and surgical outcomes were reviewed. Postoperative 30-day transient ischemic attack, stroke, and death rates were analyzed. Results were compared with ultrasound flow measurement and duplex ultrasonography. Results: From March 2013 to March 2015, 107 primary consecutive carotid endarterectomies were performed in 107 patients (71% male, 29% female). The age ranged from 51 to 81 years with a mean age of 68 ± 4 years. Associated risk factors included diabetes 89 (83%), smoking 92 (86%), hypertension 94 (87.8%), chronic renal insufficiency 71 (66%), and coronary artery disease 57 (53%). Early postoperative duplex scans in all 107 patients showed no significant changes from intraoperative findings. The ipsilateral stroke and death rate in this study was 0 (0/107) and 30-day death and stroke rate was also 0 (0/107), with no significant difference between trainees and senior surgeons. Three patients (2.8 %) had flow <100 mL/min and two of them were revised after completion contrast angiography. Conclusion: The findings of this study indicate that the intraoperative flow measurement is an alternative method for detecting technical errors and a tool for quality control imaging. Especially for the trainees, it makes sense to ensure effectiveness of the procedure upon its completion and to assess the technical adequacy of carotid endarterectomy.

Transit time flow measurement (TTFM) allows quality control in coronary artery bypass grafting but remains largely underused, probably because of limited information and the lack of standardization. We performed a systematic review of the evidence on TTFM and other methods for quality control in coronary artery bypass grafting following PRISMA standards and elaborated expert recommendations by using a structured process. A panel of 19 experts took part in the consensus process using a 3-step modified Delphi method that consisted of 2 rounds of electronic voting and a final face-to-face virtual meeting. Eighty percent agreement was required for acceptance of the statements. A 2-level scale (strong, moderate) was used to grade the statements based on the perceived likelihood of a clinical benefit. The existing evidence supports an association between TTFM readings and graft patency and postoperative clinical outcomes, although there is high methodological heterogeneity among the published series. The evidence is more robust for arterial, rather than venous, grafts and for grafts to the left anterior descending artery. Although TTFM use increases the duration and the cost of surgery, there are no data to quantify this effect. Based on the systematic review, 10 expert statements for TTFM use in clinical practice were formulated. Six were approved at the first round of voting, 3 at the second round, and 1 at the virtual meeting. In conclusion, although TTFM use may increase the costs and duration of the procedure and requires a learning curve, its cost/benefit ratio seems largely favorable, in view of the potential clinical consequences of graft dysfunction. These consensus statements will help to standardize the use of TTFM in clinical practice and provide guidance in clinical decision-making.
