Abstract
Introduction: Completion imaging following carotid endarterectomy (CEA) remains controversial. We present our experience performing routine completion arteriography (CA). Methods: A retrospective review of our prospectively maintained institutional database was performed for patients undergoing isolated CEA. Results: 1439 isolated CEAs with CA were performed on 1297 patients. CEA was for asymptomatic lesions in 70% (1003) of cases. There were no complications related to arteriography. An abnormal arteriogram documented significant abnormalities in the internal carotid artery (ICA) and prompted revision in 1.7% (24/1439) of cases: 20 unsatisfactory distal endpoints of the endarterectomy (12 residual stenoses, 7 intimal flaps, and 1 dissection), 3 kinks or stenoses within the body of the patch, and 1 thrombus. Of the 20 distal endpoint lesions, stent deployment was used in 17 cases and patch revision in 3 cases. The other 4 cases were treated by patch angioplasty (3) or thrombectomy (1). None suffered a perioperative stroke. The overall 30-day stroke, death, and combined stroke/death rate for the 1439 patients in our series was 1.5% (22), .5% (7), and 1.9% (27), respectively. The combined stroke/death rate for asymptomatic lesions was 1.1% (11/1003) and for symptomatic lesions was 2.5% (11/436). Of the 22 strokes in the entire series (all with normal CA), 15 were non-hemorrhagic strokes ipsilateral to the CEA; 14 were confirmed to have widely patent endarterectomy sites by CT-A (13) or re-exploration and repeat arteriography (1). The occluded site was re-explored and underwent thrombectomy, but no technical problems were identified. The remaining strokes were hemorrhagic (4 reperfusion syndrome and 1 surgical site bleeding) or contralateral to the CEA (2). Conclusion: Although not all patients in this series who underwent intraoperative revision due to abnormal CA might have suffered a stroke, performing this simple and safe study may have halved our overall perioperative stroke rate from 3.2% to 1.5%.

Intraoperative completion studies in carotid endarterectomy: systematic review and meta-analysis of techniques and outcomes. ANNALS OF TRANSLATIONAL MEDICINE 2021; 9:1201. [PMID: 34430642 PMCID: PMC8350645 DOI: 10.21037/atm-20-2931] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/28/2020] [Accepted: 10/16/2020] [Indexed: 11/18/2022]
Abstract
BACKGROUND Declining perioperative stroke and death rates over the past 3 decades have been paralleled by an increasing use of intraoperative completion studies (ICS) following carotid endarterectomy (CEA). Techniques applied include angiography, intraoperative duplex ultrasound (IDUS), flowmetry, and angioscopy. This systematic review and meta-analysis is aiming on providing an overview of techniques and corresponding outcomes. METHODS A PubMed based systematic literature review comprising the years 1980 through 2020 was performed using predefined keywords to identify articles on different ICS techniques. Pooled analyses and meta-analyses estimating risk ratios (RR) and 95% confidence intervals (CI) were performed to compare outcomes of different ICS modes to nonapplication of any ICS. I2 values were assessed to quantify study heterogeneities. RESULTS Identification of 34 studies including patients undergoing CEA with angiography (n=53,218), IDUS (n=20,030), flowmetry (n=16,812), and angioscopy (n=2,291). Corresponding rates of perioperative stroke were 1.5%, 1.8%, 3.6%, and 1.5%, perioperative stroke or death occurred in 1.7%, 1.9%, 2.2%, and 2.0%. Intraoperative surgical revision rates were 6.2%, 5.9%, and 7.9% after CEA with angiography, IDUS, and angioscopy, respectively. Compared to nonapplication of any ICS, the pooled analysis revealed angiography to be significantly associated with lower rates of stroke (RR 0.47; 95% CI, 0.36-0.62; P<0.0001) and stroke or death (RR 0.76; 95% CI, 0.70-0.83; P<0.0001). IDUS was significantly associated with lower rates of stroke (RR 0.56; 95% CI, 0.43-0.73; P<0.0001) and stroke or death (RR 0.83; 95% CI, 0.74-0.93; P=0.0018), whereas angioscopy showed a significant association with a lower stroke rate (RR 0.48; 95% CI, 0.033-0.68; P=0.0001), but no effect on the combined stroke or death rate. Angioscopy was associated with a higher intraoperative revision rate compared to angiography (RR 1.29; 95% CI, 1.07-1.54; P=0.006). The meta-analyses confirmed lower perioperative stroke or death rates for angiography (RR 0.83; 95% CI, 0.76-0.91) and IDUS (RR 0.86; 95% CI, 0.76-0.98) compared to non-application of any ICS, whereas flowmetry showed no significant association. CONCLUSIONS This study represents the first systematic literature review and meta-analysis on usage of ICSs in CEA. Data strongly indicate a significant beneficial effect of angiography, IDUS, and angioscopy on perioperative CEA outcomes. Any carotid surgeon should consider implementation of ICSs in his routine armamentarium.

Abstract
Ziel Der Wert der intraoperativen Angiographie und deren Ad-hoc-Beurteilung im Hinblick auf operationstechnische Unzulänglichkeiten soll geprüft werden. Methode Insgesamt 523 konsekutive A.-cartotis-Thrombendarteriektomie(TEA)-Patienten mit intraoperativer Kontrollangiographie, postoperativer Duplexsonographie und retrospektiver Zweitbeurteilung der Angiographie wurden in die Auswertung einbezogen. Ergebnisse In der retrospektiven Zweitbeurteilung der Angiographie wurden 23 (4,4%) Verschlüsse oder hochgradige Stenosen der Arteria carotis communis (ACC) oder Arteria carotis interna (ACI) im Operationsbereich (12/2,3%) bzw. in der Abstrombahn (distale extrakranielle und intrakranielle ACI, A. cerebri media [ACM]) detektiert (11/2,1%), wohingegen bei der intraoperativen Ad-hoc-Beurteilung nur 13 (2,5%) derartige Pathologien beschrieben worden waren (7/1,3% im Operationsbereich, 6/1,1% in der Abstrombahn; p=0,002). Duplexsonographisch wurden postoperativ bei 50 von 505 untersuchten Patienten (10,1%) operationstechnische Unzulänglichkeiten lokal detektiert, was signifikant mehr war als in der Angiographie (p<0,001). In den meisten Fällen handelte es sich um nicht okkludierende/nicht hochgradig stenosierende Intima-Media-Ablösungen (19), Nahteinziehungen (13) und Kinkings/Kalibersprünge am distalen Patchende (14). Nahteinziehungen und Kinkings/Kalibersprünge waren mit einer linksseitigen TEA (adjustierte OR: 2,4; 95%-KI: 1,1‑5,1), einer Operation ohne Patch (adjustierte OR: 16,6; 95%-KI: 1,3–215,0) und der Verwendung eines Dacron- vs. Polytetrafluorethylen-Patch (adjustierte OR: 3,0; 95%-KI: 1,4–6,6) assoziiert. Schlussfolgerung Bei der Ad-hoc-Beurteilung der intraoperativen Kontrollangiographie kann eine nicht unerhebliche Zahl auch okkludierender und hochgradig stenosierender Pathologien übersehen werden (zur Detektion nicht okkludierender und nicht hochgradig stenosierender operativer Unzulänglichkeiten methodisch nicht geeignet – Ausweich: postoperative Duplexsonographie).

Abstract
BACKGROUND The use of intraoperative completion imaging (completion carotid duplex ultrasound or angiography) to confirm the technical adequacy of carotid endarterectomy (CEA) remains a matter of controversy. The purpose of this study was to describe vascular surgeons' practice patterns in the use of completion imaging after CEA and to study the association between completion imaging and postoperative stroke/death and high-grade restenosis (>70%). METHODS Patients who underwent CEA without concomitant procedures in the Vascular Quality Initiative database between 2003 and 2018 were included. Surgeons' practice patterns were defined on the basis of the distribution of completion imaging use among annual CEA cases per surgeon. Multivariable and Cox proportional hazards models were used to study the association between different practice patterns of completion imaging and perioperative and 1-year outcomes after CEA. RESULTS Of 98,055 CEA cases, 26,716 (27.3%) were performed with completion imaging. Compared with cases in which completion imaging was not performed, completion imaging was associated with increased rates of immediate re-exploration (3.5% vs 0.9%; odds ratio [OR], 3.84; 95% confidence interval [CI], 2.74-5.38; P < .001), overall return to the operating room (RTOR; 1.6% vs 1.2%; OR, 1.24; 95% CI, 1.08-1.42; P < .01), and longer operative time (median [interquartile range], 105 minutes [82-132] vs 119 minutes [92-148]; P < .001). Of 1920 surgeons in our cohort, 45% never performed completion imaging, whereas 26% rarely performed completion imaging (for ≤20% of annual CEA cases), 9.5% performed it selectively (21%-79% of annual CEAs), and 19.6% used completion imaging routinely (≥80% of annual CEAs). Rarely performing completion imaging had higher rates of immediate re-exploration (6.5% vs 0.9%; OR, 7.2; 95% CI, 5.7-9.2; P < .001), in-hospital stroke (4.0% vs 1.1%; adjusted OR [aOR], 3.4; 95% CI, 2.6-4.6; P < .001), RTOR for bleeding (1.9% vs 0.9%; aOR, 2.1; 95% CI, 1.5-2.9; P < .001), and neurologic events (1.5% vs 0.4%; aOR, 3.6; 95% CI, 2.2-5.9; P < .001) compared with not performing completion imaging. It was also associated with increased stroke/death and repeated revascularization at 30 days and significant restenosis at 1 year. On the other hand, performance of selective and routine completion imaging was associated with increased immediate re-exploration (selective: aOR, 3.2 [95% CI, 1.9-5.5; P < .001]; routine: aOR, 3.7 [95% CI, 2.5-5.6; P < .001]) without any increase in in-hospital, 30-day, and 1-year adverse outcomes compared with cases performed without completion imaging. CONCLUSIONS The performance of selective or routine completion imaging during CEA is safe and is not associated with increased adverse events compared with not using intraoperative completion imaging. However, rarely performing completion imaging is associated with a significant increase in the odds of perioperative stroke/death and RTOR, possibly because of unnecessary re-exploration for minor defects. The operator's experience and establishing a criterion for fixing residual defects are important to avoid unnecessary re-exploration.

Abstract
BACKGROUND Completion imaging has been suggested for the intraoperative quality control assessment of the carotid endarterectomy technical success, in order to immediately resolve pathologic findings and accordingly improve patients' outcome. The aim of this study was to present existing evidence of different completion imaging techniques after carotid endarterectomy and their role on clinical outcome. MATERIAL AND METHODS A systematic review was performed searching in MEDLINE, CENTRAL, and Cochrane databases including studies reporting on completion imaging techniques after carotid endarterectomy. RESULTS A total of 12,378 patients in 35 studies (20 retrospective and 15 prospective) underwent a completion imaging technique after carotid endarterectomy: in 19 studies, 5340 patients underwent arteriography; in 5 studies, 2095 angioscopy; in 21 studies, 5722 DUS; and in 2 studies, 150 patients underwent transcranial Doppler. Ten studies assessed > 1 imaging technique. The mean age was 67 ± 7 years old (69% males) with common co-morbidities to be hypertension (74%), smoking (64%), and hyperlipidemia (54%). Almost half of the patients (4949; 44%) were treated for symptomatic disease. In 1104 (9.7%) patients, a major defect was identified intra-operatively, while in 329 patients (2.9%), a minor defect. Common pathological findings were the presence of mural thrombus, carotid dissection, residual stenosis, and intimal flaps. An immediate re-intervention was undertaken in 75% (790/1053) of the patients to treat a major intra-operative imaging finding. In patients with re-intervention, only 2.3% (14/609) had an intra-operative stroke and 0.8% (5/609), a transient ischemic attack, while only 1.4% (8/575) had a stroke and 0.2% a transient ischemic attack (1/575) during 30-day post-operative period. No intra-operative death was reported. In the same period, the restenosis rate of internal and common carotid artery was 0.5% (3/575) and 0.2% (1/575), respectively. CONCLUSION Completion imaging techniques can detect defects in almost 10% of patients that may lead to immediate intra-operative surgical revision with low intra-operative stroke/transient ischemic attack rate and low early carotid restenosis. During the 30-day follow-up period, in those patients, the incidence of stroke/transient ischemic attack may be low but present. This review cannot provide any evidence on which completion imaging technique is better, and the clinical impact conferred by each technique in the absence of a randomized control studies.

Abstract
Intraoperative imaging diagnostics during open vascular surgical procedures aim to enhance diagnostic certainty during the operation, ensure quality control documentation and reduce avoidable complications; however, the evidence for the various diagnostic imaging procedures with respect to improvement of perioperative outcome is not confirmed for carotid endarterectomy or for infrainguinal bypass surgery. Nevertheless, an intraoperative diagnostic control is principally recommended. The advantage of intraoperative imaging is confirmed and essential for the surgical reconstruction of bypass occlusions and acute thromboembolic occlusions.

Abstract
BACKGROUND Restenosis after carotid revascularization is clinically challenging. Several studies have looked into the management of recurrent restenosis; however, studies looking into factors associated with restenosis are limited. This study evaluated the predictors of restenosis after carotid artery stenting (CAS) and carotid endarterectomy (CEA) using a large national database. METHODS Patients undergoing CEA or CAS in the Vascular Quality Initiative data set (2003-2016) were analyzed. Patients with no follow-up (33%) and those who had prior ipsilateral CEA or CAS were excluded. Significant restenosis was defined as ≥70% diameter-reducing stenosis, target artery occlusion or peak systolic velocity ≥300 cm/s, or repeated revascularization. Kaplan-Meier survival analysis and bootstrapped Cox regression models with stepwise forward and backward selection were used. RESULTS A total of 35,720 procedures were included (CEA, 31,329; CAS, 4391). No significant difference in restenosis rates was seen between CEA and CAS at 2 years (7.7% vs 9.4% [P = .09]; hazard ratio [HR], 0.99; 95% confidence interval [CI], 0.79-1.25; P = .97). However, after adjustment for age, sex, and symptomatic status at the time of the index operation, CAS patients who had postoperative restenosis were more likely to have a symptomatic presentation (odds ratio, 2.2; 95% CI, 1.2-4.0; P = .01) and to undergo repeated revascularization at 2 years (HR, 1.75; 95% CI, 1.3-2.4; P < .001) compared with patients who had restenosis after CEA. Predictors of restenosis after CAS included a common carotid artery lesion (HR, 1.65; 95% CI,1.06-2.57; P = .03), whereas age (HR, 0.91; 95% CI, 0.84-0.99; P = .03) and dilation after stent placement (HR, 0.53; 95% CI, 0.39-0.72; P < .001) were associated with decreased restenosis at 2 years. Predictors of restenosis after CEA included female sex (HR, 1.55; 95% CI, 1.38-1.74; P < .001), prior neck irradiation (HR, 2.35; 95% CI, 1.66-3.30; P < .001), and prior bypass surgery (HR, 1.29; 95% CI, 1.01-1.65; P = .04). On the other hand, factors associated with decreased restenosis after CEA included age (HR, 0.95; 95% CI, 0.92-0.98; P < .001), black race (HR, 0.57; 95% CI, 0.37-0.89; P = .01), patching (HR, 0.61; 95% CI, 0.47-0.79; P < .001), and completion imaging (HR, 0.70; 95% CI, 0.52-0.95; P = .02). CONCLUSIONS Our results show no significant difference in restenosis rates at 2 years between CEA and CAS. Restenosis after CAS is more likely to be manifested with symptoms and to undergo repeated revascularization compared with that after CEA. Poststent ballooning after CAS and completion imaging and patching after CEA are associated with decreased hazard of restenosis; however, further research is needed to assess longer term outcomes and to balance the risks vs benefits of certain practices, such as poststent ballooning.

Abstract
BACKGROUND Eversion carotid endarterectomy (ECEA) is an effective surgical technique for the treatment of internal carotid artery (ICA) stenosis. However, a residual distal intimal flap may determine a higher rate of neurological complications. The treatment of DIF may be challenging, and no definitive approach has been described. We describe a simple surgical option for the treatment of DIF. METHODS After internal ECEA has been performed, stitches are positioned at the side of intimal flap. Suture sequence is performed from internal-external-external-internal artery wall including the everted ICA, maintaining the suture thread inside the vessel. Once the ICA is correctly repositioned, the suture thread is pulled out. Once the standard carotid anastomosis has been performed, the flap is finally tacked. RESULTS Fifteen patients have undergone surgical repair of DIF with the modified technique. No patients developed neurological complications after the surgical procedure, and all patients are still alive at last follow-up visit. CONCLUSIONS This simple technique seems a safe and feasible surgical option to correct DIF, avoiding challenging surgical procedures that may increase operative and clamping time.

Abstract
The aims of the present study were to examine the influence of a low-dose unfractionated heparin regime on platelet aggregation and to additionally assess the prevalence of primary aspirin resistance in patients undergoing carotid endarterectomy. Therefore, 50 patients undergoing carotid endarterectomy were enrolled. A bolus of 3000 IU unfractionated heparin was administered 2 min before carotid cross-clamping additionally to standard antiaggregatory therapy. Haemostaseological point of care testing was performed twice, prior to surgery and 10 min after unfractionated heparin administration by the use of aggregometric and viscoelastic point of care testing. Following unfractionated heparin administration, the activated partial thromboplastin time increased significantly and clotting time in viscoelastic INTEM test was shown to be significantly prolonged. In contrast, the antiaggregatory effect of aspirin was not diminished in aggregometric ASPI test. A low-dose unfractionated heparin regime during carotid endarterectomy was therefore considered to be safe, without diminishing the antiplatelet effect of aspirin. Moreover, aggregometric point of care testing was identified to be a suitable tool for the identification of patients with primary aspirin resistance ( n = 3).
