RESUMO
Primary leiomyosarcomas of vascular origin are rare tumors. They frequently arise within the inferior vena cava; however, the peripheral vein was also affected. To date, only a few hundred cases have been reported in the world literature. Although it is an extremely aggressive tumor, the symptoms may be unspecific, especially in the lower extremities. In this report, we present a case of primary vascular leiomyosarcoma, arising from the short saphenous vein, with symptoms mimicking thrombus in the initial diagnosis. The diagnosis of leiomyosarcomas was confirmed by standard H&E staining and immunohistochemical staining. Recurrence of the tumor has been observed five years after surgical treatment. Due to its rarity, experience in the management of this type of tumor is limited. The mainstay of treatment for these tumors is complete surgical resection. The purpose of the presented case is to discuss the clinicopathological features and management options of this tumor, under the light of the most recent literatures.
RESUMO
BACKGROUND: Few data is available concerning the association between peripheral arterial disease (PAD) and red cell distribution width (RDW). In this study, we analyzed the relationship between RDW and atherosclerosis of the vessels other than coronary arteries in patients who had undergone digital substraction angiography (DSA). METHODS: This study included 730 patients who had undergone DSA. Patients were divided into two groups according to their angiographic images. The association between RDW and atherosclerosis of peripheral arteries was analyzed. The relationship between atherosclerosis and smoking, hypertension (HT), diabetes mellitus (DM), hs-CRP, hemoglobin, white blood cell (WBC), triglyceride, total cholesterol, HDL and LDL cholesterol levels was assessed. RESULTS: Atherosclerosis was observed more common in male and patients with older age, HT, DM and smoking (p<0.001). hs-CRP and WBC levels were both in significantly positive association with atherosclerosis (p<0.05). However, there were no significant differences in the RDW levels, hemoglobin, triglyceride, total cholesterol, LDL and HDL cholesterol levels in the groups (p>0.05). CONCLUSION: Our results seem to demonstrate that older age, male gender, HT, DM and smoking are powerful risk factors for PAD. In contrast to the previous reports, RDW levels are found not to be associated with atherosclerosis of peripheral arteries.
RESUMO
OBJECTIVE: We investigated the effects of pedicled and semiskeletonized left internal mammary artery (LIMA) harvesting techniques on postoperative drainage in patients subjected to off-pump CABG, ignoring other advantages or disadvantages of those techniques. METHODS: The present study comprises a total of 160 subjects that underwent coronary artery bypass surgery in our clinic. Data were collected consecutively and retrospectively. An attempt was made to have similar groups in terms of demographic characteristics. Patients that underwent off-pump coronary artery bypass surgery by two surgical teams which differed only in LIMA harvesting technique were dichotomized and compared according to these techniques. The first group (Group 1) consisted of patients in whom LIMA was harvested with surrounding tissues using the pedicled technique. The second group (Group 2) consisted of patients in whom LIMA was harvested using the semiskeletonized technique, with the veins separated from surrounding connective tissues. RESULTS: The mean amount of drainage in the first 24 hours was 706.1±234.2 ml vs. 591±258.8 ml (Group 1 vs. Group 2; P=0.005), the mean amount of drainage in the second 24 hours was 270±133.6 ml vs. 189.4±140.4 ml (Group 1 vs. Group 2; P<0.001), and the mean amount of total drainage was determined to be 976.1±306.9 ml vs. 781.2±335.5 ml (Group 1 vs. Group 2; P<0.001). CONCLUSION: It was observed that semiskeletonized LIMA presents reduced amount of postoperative drainage in the first and second 24-hour periods and total amount of drainage than pedicled LIMA, independent of pleural integrity.

BACKGROUND: Although several clinical trials have compared surgical outcomes between off-pump and on-pump coronary artery bypass grafting (CABG), whether there is a difference in the early- and medium-term postoperative coronary microvascular functions is not fully understood. We compared short- and medium-term coronary microvascular function after off-pump and on-pump CABG. METHODS: A prospective study of patients undergoing off-pump and on-pump CABG. Eighty-two patients scheduled for CABG were recruited: 38 underwent off-pump surgery and 44 on-pump surgery. Each participant's coronary flow reserve (CFR) and diastolic function were measured with transthoracic Doppler echocardiography six and 12 months after surgery. RESULTS: Baseline and hyperaemic diastolic peak flow velocity in the left anterior descending artery were similar in both groups, as was CFR (2.22±0.66) in the off-pump group compared with (2.13±0.61) in the on-pump group, (P=0.54). Coronary flow reserve was significantly and inversely correlated with high sensitivity C-reactive protein concentration (r=-0.416; P<0.001) and positively correlated with mitral E/A-wave velocity ratio (r=0.247; P=0.02). Stepwise linear regression analysis revealed that only high sensitivity C-reactive protein concentration was independently correlated with CFR (ß=-0.272, P=0.02). CONCLUSIONS: Heart-lung bypass technique had no medium-term influence on the coronary microcirculation, despite a possible initial unfavourable effect. Serum hs-CRP concentration was an independent predictor of medium-term coronary microvascular dysfunction.

ABSTRACT OBJECTIVE: The present study consisted of patients who underwent on-pump coronary artery bypass grafting (CABG) and off-pump CABG and investigated effect of using cardiopulmonary bypass (CPB) on the amount of postoperative drainage and blood products, red blood cell (RBC), free frozen plasma (FFP) given in the intensive care unit in 60-80-year-old patients who underwent CABG. METHODS: The present study comprises a total of 174 patients who have undergone coronary artery bypass graft (off-pump or on-pump CABG) surgery in our clinic in between 2012-2015 year. RESULTS: It was observed that the amount of drainage in the first 24 postoperative hours was lower in the on-pump CABG group (Group 1) when compared to off-pump group (Group 2) (Group 1 vs . Group 2; 703.5±253.8 ml vs . 719.6±209.4 ml;P =0.716). However, the amount of drainage in the second 24 hours was statistically significantly lower in the off-pump CABG group (Group 1 vs . Group 2; 259.8±170.6 mlvs . 190.1±129.1 ml; P =0.016). With regard to the amount of overall drainage, no statistically significant difference was observed between the two groups. Group 1 needed RBC transfusion higher than Group 2 (Group 1 vs . Group 2; 2.2±1.3 bag vs . 1.2±0.9 bag;P <0.001). CONCLUSION: We can say that CPB influences the amount of second 24-hour drainage which indexed body surface area. In addition, CPB decreases hct, hb, thrombocyte count in ICU arrived, after 24 hours in postoperative period. Reduced thrombocyte counting effect can be appeared after 48 hours in the postoperative period of CPB.

AbstractObjective:The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting.Methods:A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden) heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11.Results:The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump) as compared to Group 2 (off-pump). But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893), P>0.05 for bilateral pleural effusion (P=0.780)]. Left pleural effusion was encountered to be lower in Group 2 (off-pump). The difference was found to be statistically significant (P<0.05, P=0.006).Conclusion:Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.
ResumoIntrodução:O presente estudo investigou efeito da utilização de bomba em derrame pleural pós-operatório nos casos de pacientes que se submeteram à cirurgia de revascularização miocárdica.Métodos:Um total de 256 pacientes que foram submetidos à cirurgia de revascularização isolada no ambulatório de Cirurgia Cardiovascular foram incluídos no estudo. Máquina coração-pulmão Jostra-Cobe (Modelo 043213 105, VLC 865, Suécia) foi utilizada em cirurgia de revascularização miocárdica com circulação extracorpórea. Cirurgia de revascularização miocárdica sem circulação extracorpórea foi realizada utilizando Octopus e Starfish. Anastomose proximal na aorta, em ambas as técnicas, foi realizada por grampos laterais. Os pacientes receberam alta do hospital entre os dias 6 e 11 de pós-operatório.Resultados:A incidência de derrame pleural à direita pós-operatória e derrame pleural bilateral encontrada foi mais elevada em contagem do Grupo 1 (com circulação extracorpórea) em relação ao Grupo 2 (sem circulação extracorpórea). Mas a diferença não foi estatisticamente significativa [P>0,05 para derrame pleural à direita (P=0,893), P>0,05 para derrame pleural bilateral (P=0,780)]. O derrame pleural esquerdo encontrado foi menor no Grupo 2 (CEC). A diferença foi estatisticamente significativa (P<0,05, P=0,006).Conclusão:Sob a luz destes resultados, pode-se dizer que derrame pleural esquerdo é menos prevalente nos pacientes que foram submetidos à revascularização do miocárdio sem circulação extracorpórea em comparação com os pacientes que foram submetidos à revascularização do miocárdio com circulação extracorpórea.

BACKGROUND: The aims of this study were to investigate the appearance of paradoxical ventricular septal motion (PSM) after coronary artery bypass graft (CABG) surgery and to identify factors that might be related to this abnormality. METHODS: This prospective study included 119 consecutive patients (38 women, 81 men) who underwent CABG. Patients who underwent on-pump surgery (22 women, 45 men) and patients who underwent off-pump surgery (16 women, 36 men) were studied separately. All subjects underwent preoperative angiographic septal perfusion evaluation, pre- and postoperative echocardiography, and standard electrocardiographic and laboratory investigations, including troponin I and CK-MB levels. Multivariate logistic regression analysis was also performed for a variety of related parameters. RESULTS: Significant differences in EuroSCORE, length of intensive care unit stay, length of hospital stay, PSM (assessed using echocardiography), septal perfusion (observed using preoperative angiography), postoperative pleural effusion, and intensive care unit recidivism were observed between the two groups (P < .05). Moreover, postoperative PSM was correlated with septal perfusion (r = -0.687**, P < .001), type of operation (r = -0.194*, P = .035), diabetes mellitus (r = 0.273**, P = .003), carotid stenosis (r = 0.235*, P = .011), the number of distal anastomoses (r = 0.245**, P = .008), pleural effusion (r = 0.193*, P = .037), and intensive care unit recidivism (r = 0.249**, P = .007). However, multivariate analysis demonstrated that only preoperative septal perfusion (odds ratio: 0.037; 95% confidence interval: 0.011-0.128; P < .05) constitutes an independent risk factor for PSM (P < .05). CONCLUSIONS: This study demonstrated that preoperative septal perfusion deficiency represents an independent risk factor for postoperative PSM in patients undergoing CABG. Further investigations addressing the timing of the appearance of PSM and the correlation of this finding with perfusion imaging studies may provide new details concerning the mechanisms that underlie this abnormality.

BACKGROUND: Serum uric acid is related to hypertension and cardiovascular diseases. Masked hypertension is associated with an increase in cardiovascular risk. The aim of our study was to evaluate the serum uric acid level and its relationship with carotid intima-media thickness (IMT) in patients with masked hypertension. SUBJECTS AND METHODS: A total of 114 untreated masked hypertension patients (62 men, 52 women; mean age 44.6 +/- 7.9 years) and 38 controls (20 men, 18 women; mean age 44.8 +/- 7 years) were included in the study. All patients underwent 24-hour ambulatory blood pressure. Serum uric acid and carotid IMT were measured. RESULTS: Serum uric acid was significantly higher in masked hypertension patients when compared to the control group (5.14 +/- 1.42 mg/dl, 4.84 +/- 1.45 mg/ dl, P = 0.01). Masked hypertension patients had significantly higher carotid IMT than control subjects (0.58 +/- 0.09, 0.52 +/- 0.09, P < 0.001). The masked hypertension group was also divided into two groups according to the median value of the serum uric acid levels (median value: 5 mg/dl). Carotid IMT was significantly higher in patients with a higher uric acid when compared to those with a lower uric acid (P < 0.001). We also found that the serum uric acid level was a good predictor of increased carotid IMT at the receiver-operating characteristic curve.The area under the curve was 66% (95% confidence interval, 0.56-0.77), and the serum uric acid level was significantly predictive of a high carotid IMT (P = 0.001). CONCLUSIONS: Our data suggest that the uric acid levels were significantly higher in the masked hypertension group and elevated uric acid levels were associated with increased carotid IMT, indicating that elevated serum uric acid levels might contribute to the increase in cardiovascular risk in masked hypertension.

BACKGROUND: The long-term results of coronary artery bypass surgery depend mostly on the type of the grafts. For a long time, it has been accepted that arterial grafts are superior to venous grafts. In this study, we evaluated the angiographic patency rates of arterial and venous grafts. METHODS: The study took place between 2003 and 2013 in the Departments of Cardiovascular Surgery in Baskent University. The study included 52 patients with recurrent ischemic symptoms (of total 2183 coronary artery bypass surgery patients) following coronary artery bypass surgery. The patients were evaluated by control angiography during over mid- and long-term postoperative period (mean, 75.25 ± 35.15 months). Based on the angiographic findings, the grafts were divided into 3 groups: severe stenosis, moderate stenosis, and patent. RESULTS: The preoperative demographics (age, gender, hypertension or diabetes mellitus) were similar in the three groups. The mean numbers of distal anastomoses were 3.27 ± 0.89 (range 2-5), the degree of native coronary artery stenosis for radial artery anastomosis was 79.65 ± 17.72, and the mean numbers of radial artery and saphenous vein grafts were 1.19 ± 0.44 and 1.10 ± 0.89, respectively. The patency rate was 80.77%for radial arteries, 63.2% for saphenous veins, and 82.4% for left internal thoracic arteries in the three groups. CONCLUSION: The internal thoracic artery graft was confirmed to be the best option for aorta-coronary bypass surgery, as it has the highest patency rate compared to the other grafts. Radial artery and saphenous vein patency rate were also seen to be similar in the long-term.

OBJECTIVE: Idiopathic dilated cardiomyopathy (IDC) impairs and reduces coronary flow reserve (CFR). High level of red cell distribution width (RDW) is an independent risk factor for cardiovascular diseases. Therefore, in this observational case-control study we have aimed to determine whether RDW level is associated with CFR impairment in patients with IDC. METHODS: We examined 36 patients with IDC and 35 healthy subjects formed as a control group. In addition to this, patients with IDC were divided into two subgroups according to their CFR levels [normal CFR group (CFR value ≥2) and lower CFR group (CFR value<2)]. Control and patients groups were compared using the student t-test for multiple comparisons. The subgroups were compared using the Mann-Whitney U test for continuous variables and chi-square for categorical variables. The Pearson's and Spearman correlation analysis was used to test the possible associations between CFR and the study variables as appropriate. The receiver-operating characteristic (ROC) curve was determined to evaluate the predictive performance of RDW to detect low CFR. RESULTS: There were no significantly differences between the lower and higher CFR groups' clinical data, baseline hemodynamic, medication and biochemical data except RDW and high-sensitivity C-reactive protein levels. We found that RDW level was a good predictor of low CFR at the receiver-operating characteristic curve. The area under the curve (AUC) was 73% (95% confidence interval between 0.56-0.90 is 95%, p: 0.018) After adjusting potential confounders include age, body-mass index, blood pressure, lipid and glucose, RDW independently associated with CFR level (Beta:-0.374; p=0.015) and hsCRP value (Beta:-0.520; p=0.001) were the independent predictors of lower CFR. CONCLUSION: Results showed that there was an independent correlation between RDW level and CFR level in patients with IDC.

INTRODUCTION: There are only a limited number of studies on the link between mild renal failure and coronary artery disease. The purpose of this study is to investigate the effects of mild renal failure on the distal vascular bed by measuring the coronary flow reserve (CFR) in transthoracic echocardiography after coronary artery bypass grafting (CABG). METHODS: The study included 52 consecutive patients (12 women and 40 men) who had undergone uncomplicated CABG. The patients were divided into 2 groups. Group 1 included patients with a preoperative glomerular filtration rate (GFR) of 60-90 (mild renal failure), and group 2 included those with a GFR >90. The CFR measurements were carried out through a second harmonic transthoracic Doppler echocardiography. RESULTS: The mean age was 60.08 ± 1.56 years in group 1 and 60.33 ± 1.19 in group 2. The mean preoperative CFR was 1.79 ± 0.06 in group 1 and 2.05 ± 0.09 in group 2. The mean postoperative CFR was 2.09 ± 0.08 in group 1 and 2.37 ± 0.06 in group 2. There was a statistically significant difference between the 2 groups as to preoperative creatinine clearance, preoperative estimated GFR, postoperative day 7 creatinine clearance, postoperative month 6 creatinine clearance, postoperative day 7 estimated GFR, postoperative month 6 estimated GFR, preoperative CFR, and postoperative CFR (P < .05). CFR was found to be unaffected by the choice of on-pump or off-pump technique (P = .907). After bypass surgery, there was a significant increase in the mean postoperative CFR, when compared with the mean preoperative CFR (P = .001). CONCLUSION: In our study, we detected a decrease in CFR in patients with mild renal failure. We believe that in patients undergoing CABG for coronary artery disease, mild renal failure can produce adverse effects due to deterioration of the microvascular bed.

We report the case of a 75-year-old male patient who was treated in our clinic for septicemia and subacute infective endocarditis caused by toxigenic Candida albicans. Transthoracic echocardiography revealed the presence of a thrombus in the left atrial cavity, and the diagnosis was confirmed by computerized tomography. The patient was operated on urgently. Histological examination of the embolic material removed from the left atrium showed the presence of yeast and hyphal forms of Candida albicans through periodic acid-Shiff stain. The patient was readmitted to the hospital on postoperative day 15, because of reembolism, and died later on. Here we present our approach to the diagnosis and treatment of this rare condition.

Behçet's disease is a multisystemic, potentially life-threatening condition with vascular involvement and thrombotic tendency. The disease course is characterized by exacerbations and remissions. Lower extremity vein thrombosis is the most frequent manifestation of vascular involvement, followed by vena cava thrombosis, pulmonary artery aneurysms, peripheral artery aneurysms, dural sinus thrombosis and abdominal aorta aneurysms. The case in this report was considered worth reporting due to vena cava thrombosis extending from brachiocephalic to jugular vein, accompanying thrombosis of the contralateral brachiocephalic vein and jugular veins as well as simultaneous dural sinus thrombosis, and also benefit from thrombolytic therapy.

Coronary arteriography performed in a 42-year-old male patient showed communications from the left anterior descending artery to the right ventricle one month after a myocardial infarction. The area of communication did not correspond to the site of the infarction as established by electrocardiogram and previous angiography. Exactly how the fistula developed in our case remains unknown. Angiogenesis also suggests that myocardial infarction can lead to spontaneous formation of these coronary anomalies.

A 58-year-old woman with a history of childhood acute rheumatic fever and resultant mitral valve stenosis was admitted to our cardiovascular surgery clinic complaining of tachycardia, dyspnea, and chest pain. After clinical and radiological findings were evaluated, mitral valve replacement, tricuspid De Vega annuloplasty and plication, and resection of giant left atrium were performed. Atrial thrombus was removed from the top of the left atrial wall. Operation material considered as thrombus was sent to a pathology laboratory for histopathological examination. It was diagnosed with mesothelial/monocytic incidental cardiac lesion (cardiac MICE). Microscopic sections revealed that morphological features of the lesion were different from thrombus. The lesion was composed of a cluster of histiocytoid cells with abundant cytoplasm and oval shaped nuclei and epithelial-like cells resembling mesothelial cells within a fibrin network. Epithelial-like cells formed a papillary configuration in the focal areas. Mitotic figures were absent. Here we present a case which was incidentally found in a patient who underwent mitral valve replacement surgery, as a thrombotic lesion on the left atrium wall.
RESUMO
PURPOSE: Endovenous laser ablation has replaced surgical methods in the treatment of saphenous insufficiency. The aims of this study were to compare the effectiveness of 1470- and 980-nm wavelength (WL) laser systems, to compare the postoperative complication rates, and to determine the effect of laser WL on postoperative pain scores. MATERIALS AND METHODS: Between October 2010 and November 2011, 79 consecutive patients with saphenous vein insufficiency were examined. The patients who received the 980-nm treatment were defined as Group 1; 54 extremities of 47 patients were treated in this group. The patients who received the 1470-nm treatment were defined as Group 2; 36 extremities of 32 patients were treated in this group. RESULTS: Early technical success was 100% in both groups. Both major and minor complications were seen in Group 2. The complications in Group 1 were mostly major; however, three minor complications were reported in this group. The complication rates of the two groups were not significantly different. There was no statistically significant difference between the pain scores of the two groups. CONCLUSION: Early postoperative pain was the major factor that impaired quality of life. There was no relationship between the postoperative pain scores and laser WL or energy density. The laser WL did not affect technical success or occurrence of complications. Use of a suitable energy density resulted in complete occlusion in all patients with saphenous vein insufficiency.

A 74-year-old male patient was admitted to our emergency department with post-MI angina. On account of the anginal complaint that continued for three days, a coronary artery angiography was undertaken. A percutaneous transluminal coronary angioplasty was performed, followed by the implantation of a coronary stent, and coronary perfusion (TIMI-3) was achieved in the left anterior descending artery. Medical treatment (with acetylsalicylic acid, clopidogrel, metoprolol, atorvastatin and enoxaparine) and tirofiban infusion were duly administered in the coronary care unit. After twenty-four hours, however, acute dyspne, hypotension and tachycardia developed, making it necessary to perform an echocardiography. Since the echocardiography revealed a frank pericardial effusion, the patient was immediately taken to the operation room. The ventricular free wall rupture was repaired with Surgicel, which was prepared in three layers and fixed to the myocardium by tissue glue; cardiopulmonary bypass was not used. To our knowledge, our study constitutes the first case report of a tirofiban-induced free wall rupture.
