A Retrospective Analysis of Surgical Femoral Artery Closure Techniques: Conventional versus Purse Suture Technique.

BACKGROUND: Different techniques have been reported for the exploration and repair of femoral artery (FA) in patients who undergo minimally invasive cardiac surgery (MICS) and endovascular aortic surgery. We used a modified approach alternative to the conventional technique (group CT) since May 2013, which specifies a shorter groin incision and diamond-shaped hemostatic purse sutures for arteriotomy closure without the requirement of cross-clamping (group PT [purse suture technique]) and evaluated early outcomes and the complication profiles of the 2 techniques for femoral access. METHODS: In our clinic, between May 2011 and December 2015, 503 FA cannulations were performed on 345 patients who underwent MICS (n = 109, mean age 64.1 ± 17.6 years, female/male ratio 71/38), endovascular abdominal aneurysm repair (n = 158, mean age 71.3 ± 10.2 years, female/male ratio 63/95), thoracal endovascular aneurysm repair (n = 50, mean age 65.0 ± 15.3 years, female/male ratio 15/35), and transaortic valve implantation (n = 28, mean age 80.8 ± 5.9 years, female/male ratio 13/15). A total of 295 FAs were exposed via mini incision and were repaired with the PT. We compared the duration of femoral closure (FC), wound infection, and vascular complications including bleeding hematoma, thromboembolic and ischemic events, pseudoaneurysm, seroma, surgical reintervention rates, delayed hospital stay for groin complications, and existence of postoperative local luminal narrowing (LLN) at the intervention site over 25% for both groups. RESULTS: FC time (CT 14.9 ± 3.16 min, PT 6.5 ± 1.12 min, P < 0.0001), bleeding hematoma frequency (CT 6.2%, PT 1.7%, P = 0.01), and prolonged hospital stay for groin complications (CT 14.9%, PT 3.4%, P < 0.0001) were significantly lower in the PT group. Rate of technical success (CT 80.3%, PT 87.4%, P = 0.03) and event-free patient (CT 66.1%, PT 77.5%, P = 0.03) were significantly better in the PT group. There were no differences between groups in terms of ischemic events, wound infection rates, development of pseudoaneurysm and seroma, surgical reintervention rates, and LLN of FA over 25% at 6-month duplex evaluation. CONCLUSIONS: The comparison of the 2 approaches revealed the advantages of the PT in terms of bleeding hematoma and shortening in FC time and the length of hospital stay. We suggest performing a smaller skin incision for FA access and utilizing purse sutures, which allows completing the procedure without cross-clamping, thus providing a favorable approach and excellent comfort for the surgeon.

An experience in the COVID-19 pandemic period: Turkish Cardiovascular Surgery Online Board Exam 2020.

Background: The aim of this study was to provide information about the results of the Turkish Cardiovascular Surgery Board written exam, which was held online due to the pandemic. Methods: This cross-sectional study included a total of 41 cardiovascular surgeons and residents (39 males, 2 females) in November 21st, 2020 between 10:00 A.M. and 12:00 P.M. After the online exam was completed, data on participant information and answers to exam questions were obtained from the information system. Results: Of all participants, 39% were working in university hospitals. A total of 82.9% of the participants were specialists. The total mean score of the participants was 60.3±10.2 and 53.7% of them were declared successful-passed. Aortic surgery (63%), heart failure surgery (50%), and mitral valve surgery (50%) were the most incorrectly answered questions. Conclusion: With the online exam, the Board gained different experiences regarding exam planning and implementation. The Turkish Cardiovascular Surgery Board did not give up the Board exam during the pandemic period and conducted a reliable written exam with many participants.

Results of late-onset type A aortic dissection after previous cardiac surgery: Does prior coronary artery bypass grafting affect survival?

BACKGROUND: This study aims to evaluate the results of late-onset type A aortic dissection following primary cardiac surgery and to compare the outcomes of patients with or without prior coronary artery bypass grafting. METHODS: Between January 2005 and December 2015, data of 32 patients (16 males, 16 females; mean age 58.1±10.9 years; range, 45 to 73 years) who were diagnosed with acute type A aortic dissection and underwent repair with a history of previous cardiac surgery at our institution were retrospectively analyzed. The patients were divided into two groups as those with a history of prior coronary artery bypass grafting (n=16) and the patients with a previous cardiac surgery without prior coronary artery bypass grafting (n=16). RESULTS: Dissection of the ascending aorta occurred in 32 patients (late acute in 22 and late chronic in 10) who underwent previous cardiac surgery (aortic valve replacement in 12, mitral valve replacement in two, aortic valve replacement + coronary artery bypass grafting in two, coronary artery bypass grafting in 10, mitral valve replacement + coronary artery bypass grafting in four, and dual valve replacement in two patients). The mean time between the first operation and dissection was 4.0±1.5 years. Dissections were treated with the Bentall procedures (n=8), ascending aorta replacement (n=14), ascending aorta replacement + hemiarch replacement (n=4), ascending aorta + aortic valve replacement (n=4) and Bentall + arch replacement (n=2). In-hospital mortality (30-day mortality) was seen in five patients, and oneyear mortality rate was 21.85% (n=7). The survival rates of the all patients for primary cardiac surgery vs primary cardiac surgery + coronary artery bypass grafting were 81.25% vs 75% at one year, 75% vs 68.75% at three years,75% vs 56.25% at five years, 68.75% vs 56.25% at seven years, and 68.75% vs 56.25% at 10 years, respectively (p=0.71, CI: 95%). CONCLUSION: Type-A aortic dissections may develop after cardiac operations with or without coronary artery bypass grafting at any time, and irrespective of associated histologies, they may result in high overall in-hospital mortality. With careful planning by prompt intervention, the outcomes in redo sternotomy operations with or without coronary artery bypass grafting for aortic dissections would be consistent the results of spontaneous aortic dissections.
