    Acute Mesenteric Ischemia: a Disease Still Challenging Surgeons
    (Springer India, 2022) Beyaz, Metin Onur; Demir, Ibrahim; Omeroglu, Sinan; Ata, Emin Can
    Acute mesenteric ischemia is a medical emergency that has a high incidence of morbidity and mortality. The most effective way to reduce its consequences is to establish early diagnosis and revascularization. Here, we aimed to present our management and outcome. In this case series analysis, patients with acute mesenteric ischemia were examined from January 2013 to September 2018. Thromboembolectomy was applied by using a 2-3 French sized Fogarty catheter until the superior mesenteric artery flow was restored. Endarterectomy and saphenous vein patchplasty were preferred in atherosclerotic arteries. Nineteen patients were examined. Hypertension (63.2%) and atrial fibrillation (57.9%) were the most common seen comorbid factors. After embolectomy, arterial pulsation came back in 17 (89.5%) patients. Two patients had saphenous vein bypass due to the severe atherosclerosis of the mesenteric artery. Seven (36.8%) patients died on early postoperative period. Multiorgan failure developed in 2 (10.5%) patients. The survival rate was 42.1% in 46 SD17.3 months follow-up. Acute mesenteric ischemia has high mortality and morbidity because of the local and systemic effects of comorbid diseases and intestinal ischemia. The main goals of treatment should be maintaining body auto-regulation, establishing revascularization of the ischemic intestine and removing necrotic tissues.

    Identifying the optimal monopolar electrocautery output power in pedicular internal thoracic artery harvesting: 20 or 40 watts?
    (Clinics Cardive Publ Pty Ltd, 2022) Ata, Emin Can; Senturk, Gozde Erkanli; Saygi, Halil Ibrahim; Ulukan, Mustafa Ozer; Ugurlucan, Murat; Erkanli, Korhan; Beyaz, Metin Onur
    Background: Monopolar electrocautery is an important tool for harvesting the pedicular internal thoracic artery (ITA) in cardiac surgery. The different power outputs of cautery may affect graft integrity and long-term patency. This study aimed to identify the optimal threshold of electrocautery power for ITA harvest. Methods: This prospective study included 30 patients who underwent elective coronary artery bypass surgery at the Medipol Mega University Hospital. The ITA was harvested by monopolar electrocautery after a median sternotomy. The output of cautery was adjusted at 20 W in group A and 40 W in group B. Three to 4 cm of a distal ITA sample from each patient was examined under a light microscope by two independent pathologists. Results: The ITA harvest time was longer in group A (21.2 +/- 7.5 vs 10.3 +/- 8.1 min, p < 0.001) than in group B. ITA free flow was similar in the two groups (43.6 +/- 48.7 vs 51.7 +/- 45.0 ml/min, p = 0.762). Mild to moderate injury in the endothelial and sub-endothelial sample was more frequent in the low-cautery group (p = 0.0037). Conclusion: ITA endothelial integrity was found to be better preserved with 40W electrocautery. Moreover, 20W of monop-olar electrocautery may not be safe in pedicular ITA harvesting.

    Surgical Treatment of Asymptomatic Popliteal Artery Aneurysms and Mid-term Outcome
    (Springer India, 2021) Beyaz, Metin Onur; Ata, Emin Can; Demir, Ibrahim; Onalan, Mehmet Akif; Sayin, Omer Ali
    Popliteal artery aneurysm (PAA) is a rare condition with an incidence ranging from 0.8 to 2.8%; however, it constitutes approximately 70-85% of all peripheral artery aneurysms. It is asymptomatic in the majority of cases but can cause pain and edema due to venous and neuronal compression. The most severe complication is limb lost due to thromboembolic event. Although surgical treatment left its place to endovascular treatment in the 1990s, surgical treatment still maintains its importance in preventing complications. Here, we aim to report our experience and results of the surgical management of popliteal aneurysms in this study. In this retrospective study, a total of 21 patients who were operated on due to popliteal artery aneurysm between October 2017 and January 2020 were analyzed. Patients with pseudoaneurysm and those who are infected and complicated were excluded from our study. The mean age was 63.3 +/- 9.6; females were 17 (81%). Mean follow-up was 19 +/- 8 months. More than two risk factors were found in 14 (66.7%) patients. Aneurysmectomy was performed successfully in all patients. Autologous saphenous vein graft was used in 11 (52.4%), whereas 6-mm polytetrafluoroethylene (PTFE) graft was preferred in 10 (47.6%) patients. During the follow-up period, limb loss rates were 16.7% and 83.3%, respectively. The difference was statistically significant (p < 0.05). No relation was found between the aneurysm diameter and postoperative graft occlusion. Limb loss rate was high in popliteal aneurysm repair using PTFE graft due to graft occlusion; saphenous vein graft is more superior in terms of mid-term graft patency.
