N-butyl cyanoacrylate in the treatment of venous insufficiency--the effect of embolisation with ablative polymerisation.

BACKGROUND The primary objective of this multicentre prospective observational study was to evaluate the early results of a new non-thermal embolisation method using N-butyl cyanoacrylate in venous insufficiency. PATIENTS AND METHODS A total of 181 patients with a varicose vein diagnosis were treated with the VariClose: Vein Sealing Systems at four different centres. The protocol included physical and colour Doppler ultrasonography examination, venous clinical severity score and quality of life assessment before and after the procedure on days 1 and 7 and at months 1, 3 and 6. Clinical recovery was evaluated by comparing the venous clinical severity score and the quality of life assessment before and after the procedure. RESULTS In total, 215 embolisation procedures were successfully completed on 181 patients (110 female) with a mean age of 37.6 ± 13.2 years (range 18-72 years). The 215 procedures consisted of 25 bilateral applications on 206 great saphenous veins and 9 small saphenous veins. The average pre-interventional diameter of great saphenous veins was 6.5 ± 1.4 mm (4.3-14 mm), and the mean diameter of small saphenous veins was 5.2 ± 1.3 mm (3.8-8.6 mm). The average length of the sealed vein segments was 31.6 ± 6.1 cm (23-70 cm), and the average N-butyl cyanoacrylate usage for the patient was 0.9 ml (0.7-2.1 ml). The procedural occlusion rate was 100%. Post-operative pain was observed in 11 patients (6.1%), and thrombophlebitis was observed in 1 patient (0.5%). No total recanalisation was observed. Five (2.7%) partial recanalisations were observed at the 6 month follow-up. The 6 month total occlusion rate was 97.2%. CONCLUSIONS This new tumescent-free non-thermal embolisation method can be applied safely with high success rates.

A rare cause of healthcare-associated infective endocarditis: Enterobacter cloacae

We report a case of infective endocarditis secondary to healthcare-associated bloodstream infection caused by an uncommon etiologic agent, multidrug-resistant Enterobacter cloacae. The patient was treated with a combination of antimicrobial therapy and surgery, but could not be saved. With this case, we discuss the prevalence, risk factors, treatment options, and outcomes of the rarely encountered Enterobacter cloacae-associated infective endocarditis.

Perioperative outcomes in minimally invasive direct coronary artery bypass versus off-pump coronary artery bypass with sternotomy

Introduction Surgical treatment of isolated left anterior descending coronary artery disease can be performed with either minimally invasive direct coronary artery bypass via a left anterior thoracotomy (MIDCAB) or off-pump coronary artery bypass via a median sternotomy (OPCAB). Aim To compare the perioperative outcomes of patients undergoing MIDCAB or OPCAB surgery. Material and methods Patients who underwent either MIDCAB or OPCAB for isolated left anterior descending (LAD) coronary artery disease between October 2013 and December 2015 were retrospectively evaluated. Operations were carried out by the same surgical team. Preoperative, intraoperative and postoperative data of the patients were recorded for analyses. Results Twenty-three patients (7 females, 16 males) underwent MIDCAB surgery, and 24 patients (4 female, 20 males) underwent OPCAB surgery. The two groups were comparable regarding preoperative patient characteristics. Duration of mechanical ventilation (5.1 ±0.7 h vs. 6.6 ±0.9 h), intensive care unit stay (19.4 ±2.5 h vs. 45.8 ±5.4 h) and hospital stay (4.3 ±0.4 days vs. 5.6 ±0.8 days) were significantly shorter in the MIDCAB group (p < 0.01). Patients in the OPCAB group required significantly more blood transfusions (1.83 ±0.38 units vs. 0.17 ±0.38 units) and fresh frozen plasma use (2.33 ±0.96 units vs. 0.69 ±0.76 units) (p < 0.01). Conversion to sternotomy was not required in the MIDCAB group. There was no mortality, conversion to cardiopulmonary bypass or serious complication in either group. Conclusions We believe that the MIDCAB technique is more advantageous than the OPCAB technique in the treatment of patients with a critical LAD lesion.

Indwelling hemodialysis catheterization by transthoracic way

Abstract Chronic kidney failure can be described as a chronic and progressive disfunction in metabolic-endocrine function and in adjustment of fluid-electrolyte balance of kidney, as a result of reducing of glomerular filtration value. Besides being a medical issue, chronic kidney failure affects social, economic, and psychological conditions of patients. Indwelling catheters can be placed in the right atrium by right mini thoracotomy in kidney patients who depend on dialysis and all central veins are used. In the patients whose central veins were used, were able to do catheterization by this technique, and this is a procedure that must be retentioned.
