Bu çalışmada; Parafin, Polietilen glikol 600, üç farklı yüzey aktif madde (Lineer Alkil Benzen Sülfonik Asit, Setil Trimetil Amonyum Klorür ve Kokoamidopropil Betain) ve atık lastiğin kimyasal bozundurulması sonucu elde edilen Geri Kazanılmış Karbon kullanılarak Organik Faz Değişim Malzemesi üretilmiştir. Organik Faz Değişim Malzemeleri basit bir karıştırma ve vakum emdirme yöntemiyle üretilmiştir. Farklı türdeki yüzey aktif maddelerin kullanıldığı farklı kompozisyonlarda elde edilen numunelere; faz değişim sıcaklık farkı testleri yapılarak en yüksek faz değişim sıcaklık farkına sahip numuneler belirlenmiştir. Belirlenen bu numunelerin (FM13; FM20 ve FM26 Kodlu) kimyasal ve termal özellikleri, Fourier Dönüşümlü Kızılötesi Spektrotometresi ve Diferansiyel Taramalı Kalorimetri cihazı kullanılarak belirlenmiştir. En yüksek enerji depolama kapasitesine (85,64 j/g) sahip numunenin; Setil Trimetil Amonyum Klorür yüzey aktif maddesi içeren FM-26 kodlu numune olduğu belirlenmiştir.
Aims: Carotid artery disease is one of the most important causes of stroke. If left untreated, it causes serious mortality and morbidity. The gold standard treatment for carotid artery stenosis is carotid endarterectomy. The use of shunt, primary or patch closure of the arteriotomy varies according to clinical experience. In this article, we present the results of carotid endarterectomy performed with no shunt and primary closure method. Methods: Thirty cases who underwent carotid endarterectomy in our clinic between April 2021 and April 2022 were analyzed retrospectively. All patients underwent selective carotid surgery. All surgeries were performed with the same technique and under general anesthesia. The patients were evaluated in terms of demographic characteristics, operation time, cross-clamp time, mortality, morbidity, and hospital stay. Results: The clinical data of the early follow-up in the first month postoperatively were evaluated. Six (20%) of the patients were female and 24 (80%) were male. All of the males were active smokers. The mean age was 71.1 (min:65-max:82). Twenty five patients had a history of coronary artery disease. The mean cross-clamp time was 9.1 (±0.8) minutes. All surgeries were performed without using shunts. In all patients, primary closure was performed without the use of arterotomy grafts. Conclusion: As an early morbidity, dysphagia was detected in 1 patient. This symptom disappeared at follow-up at 1 month. No early mortality was observed in any patient at 1-month follow-up. With increasing experience, carotid endarterectomy operations can be performed safely with no shunt and primary closure method. Our early surgical results are consistent with the literature.
Aneurysm is defined as 50% enlargement of the normal diameter of the artery. The most common cause of true aneurysms is atherosclerosis. Pseudoaneurysms, on the other hand, occur as a result of the blood leaking from the tear in the arterial wall forming a thrombus formation and surrounding it with a fibrous capsule. In pseudoaneurysms, blood pools in a closed area. However, they may enlarge and rupture in the late period. Treatment options are thrombin injection, endovascular graft implantation, surgical ligation, and arterial bypass. In this case report, we present a patient with a stab wound to the axilla. Two years after the injury, a pseudoaneurysm developed in the left brachial artery. The pseudoaneurysm was treated with endovascular stent graft
Aim: The aim of this study is to evaluate the results of 67 open heart surgeries performed in the first year in a new cardiovascular surgery clinic.Material and Method: Patients who underwent open heart surgery in our clinic between May 2021 and May 2022 were evaluated retrospectively. The hospitalization time, cross-clamp time, complications and mortality data of the patients were obtained retrospectively from the hospital database. In the analysis of the data, mean values were calculated for continuous variables, while percentage and frequency values were shown for categorical variables.Results: A total of 67 cases were included in the study. Isolated CABG surgery was performed on 44 patients with cardiopulmonary bypass (CPB). Isolated CABG surgery was performed on 3 patients without CPB (beating heart). CABG and mitral valve replacement (MVR) operations were performed simultaneously in two patients. MVR operation and tricuspid valve annuloplasty operations were performed simultaneously in two patients. MVR surgery was performed in four patients in isolation. Aortic valve replacement (AVR) operation was performed in 6 patients in isolation. Ascending aorta replacement was performed in three patients simultaneously with AVR operation. Bentall surgery was performed in two patients, and intra-cardiac tumor (myxoma) excision surgery was performed in one patient. Bleeding revision surgery was performed in one patient (1.5%) on the same day due to early bleeding and pericardial tamponade. Sternal dehiscence was observed in two patients in the late period (3%). Postoperative mortality was seen in a total of four patients (5.9%).Conclusion: As a result of our study, we determined that the surgeries performed in our newly opened cardiovascular clinic may have similar results to experienced clinics in terms of mortality and morbidity.
