Simple blood tests as predictive markers of disease severity and clinical condition in patients with venous insufficiency.

Chronic venous insufficiency (CVI) is a progressive inflammatory disease. Because of its inflammatory nature, several circulating markers were investigated for predicting disease progression. We aimed to investigate simple inflammatory blood markers as predictors of clinical class and disease severity in patients with CVI. Eighty patients with CVI were divided into three groups according to clinical class (grade 1, 2 and 3) and score of disease severity (mild, moderate and severe). The basic inflammatory blood markers [neutrophil, lymphocyte, mean platelet volume (MPV), white blood cell (WBC), platelet, albumin, D-dimer, fibrinogen, fibrinogen to albumin ratio, and neutrophil to lymphocyte ratio] were investigated in each group. Serum neutrophil, lymphocyte, MPV, platelet count, D-dimer and neutrophil to lymphocyte ratio levels were similar among the groups (P > 0.05). Although the serum WBC levels were significant in the clinical severity groups (P < 0.05), it was useless to separate each severity class. However, albumin, fibrinogen and the fibrinogen to albumin ratio were significant predictors of clinical class and disease severity. Especially, the fibrinogen to albumin ratio was detected as an independent indicator for a clinical class and disease severity with high sensitivity and specificity (75% sensitivity and 87.5% specificity for clinical class and 90% sensitivity and 88.3% specificity for disease severity). Serum fibrinogen and albumin levels can be useful parameters to determine clinical class and disease severity in patients with CVI. Moreover, the fibrinogen to albumin ratio is a more sensitive and specific predictor of the progression of CVI.

Does the direction of tumescent solution delivery matter in endovenous laser ablation of the great saphenous vein

Background: The aim of this study was to compare the two different directions of tumescent solution delivery (from distal to proximal knee to the saphenofemoral junction [SFJ] or proximal to distal SFJ to the knee) in terms of differences in tumescent volume, number of punctures, and pain and comfort scores of patients. Methods: A total of 100 patients were treated with endovenous laser ablation (EVLA) under local anesthesia between August 2013 and October 2013. These 100 patients were divided into two groups. In group 1, tumescent solution was delivered in a proximal to distal direction. In group 2, the tumescent solution was delivered in a distal to proximal direction. In each group, the great saphenous vein (GSV) diameter, delivered total energy, treated GSV length, delivered tumescent volume, number of punctures, and pain and comfort scores were recorded for each patient. Results: All patients were treated unilaterally. EVLA was performed with 100% technical success in all patients. There was no difference statistically between group 1 and group 2 according to GSV diameter, delivered total energy, and treated GSV length. Average tumescent volume, number of punctures, and pain scores in group 2 were lower than in group 1 (p = 0.0001; p < 0.05). Also, the average comfort score was higher in group 2 than in group 1 (p = 0.0001; p < 0.05). Conclusions: We believe that delivering the tumescent solution in a distal to proximal direction increases the comfort of both patient and surgeon with lower tumescent volume during the EVLA of the GSV.

The relationship between fibrinogen to albumin ratio and severity of coronary artery disease in patients with STEMI

OBJECTIVE Previous studies show that serum fibrinogen levels are established risk factors for coronary artery disease (CAD) and that serum albumin levels are of a higher specificity and sensitivity in ST-elevation myocardial infarction (STEMI). In this study, we sought to evaluate the association between fibrinogen to albumin ratio (FAR) and the extent and severity of CAD evaluated by TAXUS Drug-Eluting Stent Versus Coronary Artery Bypass Surgery for the Treatment of Narrowed Arteries (SYNTAX) Score (SS) in patients with STEMI. METHODS A total of 278 patients with STEMI were included in the study. FAR was calculated using specified variables. The extent and severity of CAD were evaluated using the SS. The patients were divided into low- (SS <22) and high- (SS ≥22) risk groups. A Spearman rank correlation coefficient analysis was used for the relationship between FAR and SS. The cutoff points for sensitivity and specificity of FAR in predicting SS were estimated by performing a receiver operator characteristic curve analysis. RESULTS There were significant differences in the mean age (P=.016), admission serum albumin (P=.041), serum fibrinogen (P<.001), FAR (P<.001), and SS risk groups. Positive correlation was detected between FAR and SS (r=0.458, P<.001). A cutoff level of >87 FAR predicted SS (sensitivity, 70%; specificity, 70%), and an area under the curve of 0.758 serum fibrinogen and albumin level was an independent predictor for SS in patients with STEMI (b=0.039; 95% confidence interval, 0.016-0.062; P=.001 and b=-6.906; 95% confidence interval, -12.284 to -1.527; P=.013, respectively). CONCLUSION In the present study, we showed that FAR is significantly related to SS in predicting the severity of CAD in patients with STEMI.

Investigation of possible prophylactic, renoprotective, and cardioprotective effects of thromboprophylactic drugs against ischemia–reperfusion injury

The aim of this study was to investigate whether anticoagulant and antiaggregant agents have protective effects against oxidative damage induced by peripheral ischemia–reperfusion (I/R). Groups were created as follows: control group, I/R group (sham group), I/R plus acetylsalicylic acid (Group I), I/R+clopidogrel (Group II), I/R+rivaroxaban (Group III), I/R+bemiparin sodium (Group IV), and I/R+enoxaparin sodium (Group V). In Groups I, II, III, IV, and V, drugs were administered daily for 1 week before I/R creation. Peripheral I/R was induced in the I/R groups by clamping the right femoral artery. The rats were sacrificed 1 hour after reperfusion. Nitrogen oxide levels, malondialdehyde (MDA) levels, paraoxonase‐1 (PON1) activity, and prolidase activity were evaluated in both cardiac and renal tissues. There was no significant difference in nitrogen oxide levels between the groups. However, cardiac and renal MDA were significantly higher and PON1 activity was markedly lower in the I/R groups compared with the control group (p < 0.05). Although elevated prolidase activity was detected in both the cardiac and renal tissue of the I/R groups, only the sham group and Group V had significantly higher renal prolidase activity (p < 0.05). Group V had significantly higher cardiac MDA, PON1, prolidase levels, and renal prolidase activity compared with the sham group (p < 0.05). Significant improvement in renal MDA levels was only observed in Group III, and marked improvement was observed in the cardiac MDA levels of Group II when compared with the sham group (p < 0.05). Thromboprophylactic agents appear to provide partial or prominent protection against I/R injury.

Protective effects of ginseng extracts and common anti-aggregant drugs on ischaemia-reperfusion injury.

Summary Objective Ginseng is a traditional herbal medicinal product widely used for various types of diseases because of its cellular protective effects. Possible protective effects of ginseng were investigated in blood, cardiac and renal tissue samples and compared with common anti-aggregant agents in an animal ischaemia–reperfusion (I/R) model. Methods Twenty rats were equally divided into four different groups as follows: control group (I/R-induced group without drug use), group I (acetylsalicylic acid-administered group), group II (clopidogrel bisulfate-administered group), group III (ginsenoside Rb1-administered group). For the groups assigned to a medication, peripheral I/R was induced by clamping the femoral artery one week after initiation of the specified medication. After reperfusion was initiated, cardiac and renal tissues and blood samples were obtained from each rat with subsequent analysis of nitrogen oxide (NOx), malondialdehyde (MDA), paraoxonase 1 (PON1) and prolidase. Results NOx levels were similar in each group. Significant decrements were observed in serum PON1 levels in each group when compared with the control (p < 0.05). Serum MDA levels were significantly lower in groups II and III (p < 0.05). Ameliorated renal prolidase levels were detected in study groups (p < 0.05) and recovered cardiac prolidase levels were obtained in groups II and III (p < 0.05). Conclusion These findings indicate that ginseng extracts may have a potential beneficial effect in I/R injury. However, more comprehensive studies are required to clarify the hypothetical cardiac, renal and systemic protective effects in reperfusioninduced oxidative damage.

Application of thoracic endovascular dissecting aneurysm repair for secondary type B aortic dissection.

Abstract Type A aortic dissection is an emergency condition that requires immediate surgery. Graft replacement of the ascending aorta is the main treatment for this disorder. However, after ascending aortic replacement, the dissection flap may progress to the distal side (to the descending aorta) and a new intimal tear may develop. In this study, we report on a 66-year-old woman who had a history of ascending aortic replacement six months earlier. She was admitted to hospital with a new onset of back pain. Computed tomography revealed a new dissection tear originating from the distal side of the subclavian artery orifice. Thoracic endovascular dissecting aneurysm repair (TEVDAR) was carried out on the patient. Additional complications were not observed in the postoperative period. Complete cure was provided and the patient was discharged on the fourth day after the operation. TEVDAR may be safe and effective in preventing progression of the aortic flap and the formation of a new intimal tear in type A aortic dissections. Optional hybrid interventions could ameliorate the outcomes in aortic dissection cases.

Pharmacomechanical thrombolysis with a rotator thrombolysis device in iliofemoral deep venous thrombosis.

Objective Deep venous thrombosis (DVT) is a life-threatening and morbid pathology. This study aimed to investigate the efficacy of an early thrombolysis procedure using a rotator thrombolysis device. Methods Sixty-seven patients with acute proximal DVT were enrolled in the study. Patients’ data were recorded retrospectively. Initially, an infrarenal retrievable vena cava filter was placed through the femoral vein. Then, a rotator thrombolysis device and a thrombolytic agent injection were applied to the occluded segments of the deep veins by puncturing the popliteal vein. Results The identified reasons were trauma (43.3%), pregnancy (20.9%), undiagnosed (11.9%), major surgical operation (10.5%), immobilization (7.5%), and malignancy (5.9%). Immediate total recanalization was conducted in all patients, and the leg diameters returned to normal ranges in the early postoperative period. Hospital mortality or severe complications were not detected. Conclusion New thrombolytic devices seem to reduce in-hospital mortality risks and may potentially decrease post-thrombotic morbidity.

An evaluation of factors affecting clinical outcomes in penetrating cardiac injuries: A single center experience

BACKGROUND Penetrating cardiac injury (PCI) has highly mortal outcome. Therefore, management of this emergency situation is extremely important. The present study is an investigation of main factors that can affect mortality and morbidity in PCI. METHODS Records of 112 patients who were admitted to emergency department with PCI in the last decade were evaluated retrospectively. Demographic data, initial approach, transfer duration and conditions, vital status and findings, type of injury, localization, characteristics, and type of surgical application were recorded. RESULTS Demographic findings (age, sex, cause of injury) were not found to be significant factors affecting mortality. Early mortality (1-week observation period) occurred in 14 (12.5%) patients. Method of transfer to hospital (under medical team supervision by ambulance, or without supervision), transfer duration, initial vital findings upon arrival (blood pressure, rhythm, breathing, consciousness), operation timing (elective or emergency), and injuries to additional organs were determined to be important predictors of survival. CONCLUSION Cardiac injury is highly mortal emergency situation. Expert medical management is important for survival. However, basic first aid measures and immediate hospital transfer are as important as expert clinical management.

Unexpected complication of oesophagoscopy: iatrogenic aortic injury in a child

Summary Introduction Oesophagoscopy is usually a safe procedure to localise and remove ingested foreign bodies, however, unexpected complications may develop during this procedure. In this case report we discuss iatrogenic aortic injury, which developed during oesophagoscopy, and its immediate treatment. Case report A six-year-old male patient was admitted to hospital with symptoms of having ingested a foreign body. Oesophagoscopy was carried out and the foreign body was visualised at the second constriction of the oesophagus. During this procedure, profuse bleeding occurred. Subsequently, a balloon dilator was placed to control bleeding in the oesophagus. Thoracic contrast tomography revealed thoracic aortic injury. Open surgical aortic repair was immediately carried out on the patient and the oesophageal hole was primarily repaired. The patient was discharged on postoperative day 15 with a total cure. Conclusion Although oesophagoscopy is a safe, easily applied method, it should be kept in mind that fatal complications may occur during the procedure. This procedure should be done in high-level medical centres, which have extra facilities for managing complications.

Periferik damar yaralanmaları analizi: Sosyal bir katastrofi

Objective: In the current study, peripheral vascular injuries caused from weapons and the associated clinical outcomes were retrospectively investigated. Methods: Two hundred patients who received a surgical procedure for a vascular injury between January 2009 and December 2011 were included in the study. The patients were evaluated retrospectively; type of injury, localization, characteristics, and type of surgical application were classified. Results: Weapon-related penetrating injuries were classified as gunshot injuries (n=55, 28%), stab wounds (n = 143, 71%), and mine injuries (n= 2, 1%). There were 77 interposition applications (71 arterial and 6 venous) with saphene vein grafts, 16 arterial interposition applications with polytetrafluoroethylene grafts, and 11 venous ligations. A total of 170 direct repairs (134 arterial and 36 venous) were performed. Postoperative amputation was required in none of the cases, advanced intensive care unit follow-up was required for four patients (2%; two cases were referred with hypovolemic shock and two case were referred with asystole), and a postoperative follow-up period for any mortality was not observed. Conclusion: Some regions contain higher levels of war injuries. Therefore, these regions require specialized intervention centres. A large amount of these injuries are vascular, and surgery and rapid interventions are essential for reducing mortality and morbidity rates. Successful results can be obtained in these cases through the collaboration of various medical disciplines.
