Double left anterior descending (LAD) artery is a rare coronary artery anomaly. Most coronary artery anomalies are usually asymptomatic. In this case report we describe a patient with double LAD with two branches of almost equal caliber and parallel. Both of the branches had significant proximally stenosis and this condition was demonstrated intraoperatively. This normally originated double LAD may be considered interesting. We revascularized the double LAD with bypass grafting.

Duodenal necrosis is one of the causes of peritonitis. It remains a well-known surgical emergency requiring prompt surgical intervention. Duodenal necrosis mostly occurs following iatrogenic devascularisation of a duodenal stump or in the course of necrotising pancreatitis. We present a case of idiopathic necrosis of the fourth part of the duodenum without a certain aetiologic cause in a 69-year-old woman who was admitted to our hospital with acute abdomen findings. Abdominal computed tomography scan revealed abnormal results. Laparotomy was performed and the case was successfully treated with tube duodenostomy. ©Copyright 2012 by G . . .azi University Medical Faculty Daha fazlası Daha az

Background: The aim of this study was to evaluate our arteriovenous fistula experience and success rate and the surgical technique in arteriovenous fistula operations for haemodialysis access. Methods: We retrospectively reviewed 165 consecutive operations for haemodialysis access performed in our department from January 2003 to December 2005. They were evaluated for the type of operation, localization and complications. Results: No grafts were used in this series of 165 consecutive operations. The 6-month patency rates of native fistulas were 90%, 93% and 93% for the snuffbox, radiocephalic and brachiocephalic fistulas, respectivel . . .y. The complication rate was 13% and the most common complication was thrombus formation. Conclusion: For all arteriovenous fistulas, the aim should be a long duration of patency and productivity. Patency rates of brachiocephalic fistulas are comparable to those of radiocephalic fistulas. Native fistulas are reliable, safe and simple procedures with access sites often available in both the forearm and the upper arm Daha fazlası Daha az

A 35-year-old male patient was seen with pulsatile swelling in the left antecubital fossa and a flexion defect in the thumb and adjacent finger 50 days after suffering a stab wound. A cardiovascular examination revealed weak pulsation in the brachial, radial and ulnar arteries. The neurological findings included an extension defect of the forearm in addition to the flexion defect in the fingers. During surgery, a false aneurysm of the brachial artery was confirmed and a short segment of the brachial artery was excised with the aneurysm and replaced with a saphenous vein graft. In this setting, the median nerve examination was perfor . . .med by neurosurgery experts. One month later, the patient had fully recovered and had returned to his normal occupation Daha fazlası Daha az

Double LAD with same origin (type I, II, III) is a rare congenital anomaly, however double LAD arising from right and left main coronary arteries is even more rare (type IV). A 49-year-old male patient was referred to our center with typical angina. Echocardiography revealed depressed left ventricular systolic functions. Coronary angiography showed a terminated LAD in the middle portion of the anterior interventricular sulcus after giving first diagonal and septal branches and a second LAD originating from different ostium in the right coronary sinus and extending to interventricular sulcus distally. The aforementioned findings were . . . compatible with type IV LAD coronary artery anomaly. Herein we aimed to share our revascularization experience in a patient with congenital type IV LAD anomaly. © Copyright 2015 by Gazi University Medical Faculty Daha fazlası Daha az

Objective: Carpal tunnel syndrome (CTS) is the most common peripheral trap neuropathy resulting from compression of the median nerve in the carpal tunnel of the wrist. Open release of the transverse carpal ligament is now the most commonly used method. New techniques are being developed to avoid complications of standard long curvilinear incision. Methods: Between March 2010 and January 2016, carpal tunnel release was performed by the same surgeon with 110 minimally invasive techniques in 96 patients due to CTS. Complaints and physical examination findings were compatible with CTS and mid- to severe-severity CTS cases supported by E . . .MG were included in the study. Results: Complaints and examination findings were recorded at the postoperative 1st year outpatient clinics of the patients. Of the110 carpal tunnel release, in 50 patients (%45,5) total, in 45 patients (%40.9) significant, in 13 patients (%11,8) slight improvement were recorded, while no improvement was recorded in 2 patients (%1,8). They stated that 88% of the patients were satisfied with the operation and 12% were not satisfied. Visual Analog Scale (VAS) was used to evaluate pain complaints. The mean VAS score was 7,5 pre-operatively and 3,2 at post-operatively 1 year follow-up. Conclusion: In patients with CTS, median nerve decompression with minimal wrist incision is an effective and reliable surgical procedure. © Copyright 2018 by Gazi University Medical Facult Daha fazlası Daha az

The ankylosing spondilitis a chronic rheumatic inflammatory disorder characterized by the involvement of vertebrae and sacroiliac joints. It may attack eyes, alimentery system, heart and kidneys extraarticulary, and it can cause cardiovasculary complications in a range of an asymptomatic course to high morbidity and mortality. Hence a timely diagnosis is of prime clinical importance. A female patient of 53 years of age applied to our hospital with angina pectoris and her medical history revealed a 16 years of follow-up due to ankylosing spondilitis in another health institution. The echocardiography established a left ventricular wa . . .ll motion abnormality and a mild mitral insufficiency. In the elective coronary angiography the ectatic LAD was detected to be stenozed and a LIMA single vessel by-pass was planned for this patient. In this report, we would like to enroll our experience of coronary revascularization on an ectatic coronary artery with stenosis in an ankylosing spondylosis patient. ©Copyright 2014 by Gazi University Medical Facult Daha fazlası Daha az

Objective: To compare the feasibility of the EuroScore and STS (The Society of Thoracic Surgeons) risk scoring systems for predicting the surgical mortality of isolated coronary artery bypass surgery patients. Materials and Methods: The risk scoring of 148 patients who were operated on between November 2002 and December 2005 was performed prospectively according to the EuroScore and STS risk scoring systems. The predicted and observed mortality rates according to each scoring system were compared. Results: Hospital mortality was 2% (3 patients). The predicted mortality rate according to EuroScore was 3.4±2.2%, whereas it was 3.0±2.1 . . .% for STS. There were no significant differences between predicted and observed mortality rates according to either scoring system. The area under the receiver operating characteristic curve was 0.83 for EuroScore and was 0.82 for STS (p>0.05). Conclusion: Both scoring systems were efficient for predicting mortality rates for our patient population. It is an advantage of STS that it also gives valuable information about morbidity Daha fazlası Daha az

Amaç: Kafein (1, 3, 7 trimetilksantin) bir pürin alkoloit olarak birçok yiyecek ve içeceklerin içeriğinde bulunur. Kahve, çay, çikolata, kola ve bazı gazlı içecekler kafein ihtiva eder. Biz çalışmamızın temel hedefi olarak, kısa süreli oral kafein alımının rat karaciğerinde olası antioksidan etkilerini iki farklı dozda araştırmaya çalıştık. Yöntemler: Kafein verilen ratların karaciğer dokularında lipit peroksidasyon ürünü olan MDA düzeylerini ölçtük. Bunun yanında kafeinin antioksidan özelliğini incelemek için, enzimatik ve non enzimatik antioksidan sistem üzerinde araştırmalar yaptık. Karaciğer dokularında SOD, katalaz, GPx, GST ak . . .tivitelerini ve GSH düzeylerini ölçtük. Çalışmamızda 30 adet (ortalama 250 gr ağırlığında) Wistar cinsi erkek rat kullanıldı. Ratlar üç eşit gruba ayrıldı. Grup 1: Kontrol grubuydu. Grup 2’ye 30 mg/kg, Grup 3’e 100 mg/kg (nontoksik yüksek doz) kafein 14 gün boyunca (kısa süreli) oral yol ile verildi. Bulgular: Çalışmamızın sonuçları, 14 gün düşük doz (30 mg/kg) ve toksik olmayan yüksek doz (100 mg/kg) kafein uygulamasının, karaciğerde lipit peroksidasyonununu azalttığını göstermektedir. Kafein alımıyla rat karaciğer dokusunda SOD, katalaz, GPx ve GST gibi antioksidan enzim aktivitelerinde ise istatistiksel olarak anlamlı artış saptanmıştır. Karaciğer dokusu glutatyon düzeyleri karşılaştırıldığında kontrol grubuna göre kafeinli gruplarda hafif artış tespit edilmiş, ancak gruplararasında istatistiksel olarak anlamlı fark bulunmamıştır. Spearman korelasyon analizi sonuçlarına göre doku MDA düzeyi azalırken, GPx, GST, SOD aktivitesi artmış ve güçlü negatif korelasyon görülmüştür. Doku GST aktivitesi ile doku katalaz aktivitesi arasında güçlü pozitif korelasyon bulunmuştur. Sonuç: Kafeinin bu dozlarda; lipit peroksidasyonunu azaltması, antioksidan enzim aktivitelerini artırması ile oksidatif stresi iyileştirmesi, yapılan araştırmaların da ışığında antioksidan olabileceği görüşünü desteklemektedir. Kafeinin antioksidan olarak uygun dozunun belirlenmesinde, etki mekanizmalarının açığa kavuşturulmasında ileri hayvan ve insan çalışmalarının gerekli olduğunu düşünmekteyiz. (Gazi Med J 2012; 23: 13-8) Objective: Caffeine (1, 3, 7-trimethylxanthine) is a purine alkaloid which exists in a variety of foods and drinks. Today, caffeine is a regularly consumed substance, found in coffee, tea, chocolate and cola. The main aim of our study was to compare the potential antioxidant effects of oral caffeine intake in rat the liver at two different doses over a short period of time. Methods: We measured malondialdehyde (MDA) levels, which is a product of lipid peroxidation, in rat livers following caffeine administration. In addition, we evaluated superoxide dismutase (SOD), catalase, glutathione peroxidase (GPx) and glutathione S transferase (GST) activities as well as glutathione (GSH) levels in the liver. Thirty male Wister rats were used. Rats were equally divided into three groups. Group 1 was the control group, Group 2 received 30 mg/kg of caffeine and Group 3 received 100 mg/kg caffeine (non-toxic high dose) orally for 14 days (a short time period). Results: Our results showed that the 30mg/kg and 100 mg/kg caffeine doses decreased lipid peroxidation in liver. Antioxidant enzyme activities in the rat liver, like SOD, catalase, GPx and GST, showed a statistically significant increase with caffeine intake. Liver glutathione levels, in comparison to the control group, showed a slight increase, but this was not statistically significant. Results from the Spearman analysis showed a strong negative correlation between MDA levels and GPx, GST and SOD activities. Tissue GST activity and tissue catalase activity showed a strong positive correlation. Conclusion: Decreased lipid peroxidation and increased antioxidant enzyme activities demonstrate improved control of oxidative stress, suggesting that these doses of caffeine may have antioxidant activity.
