We report two patients who sustained vascular injury while undergoing intervertebral disc surgery at the lumbar four and five level. Each patient suffered from massive bleeding and shock, urgent laparatomy was performed, and the vascular injuries were successfully primarily repaired. The experience prompted us to review reports in the literature since 1965 of vascular complications associated with surgical excision of hernia disc via a posterior approach. From our analysis, we highlight the clinical features and management, emphasising that rapid diagnosis and immediate intervention can result in a favourable outcome, as in our patients.

While primary arteriovenous fistula patency was shortened in chronic renal insufficiency patients with diabetes mellitus, presence of malignancy, and previous catheter insertion, patency was longer in patients with heparin used for hemodialysis and hemodialysis count per week (> or =3).

As a result, we think that the evaluation of inflammation before creating AVF in HD patients is very important for increasing the success of AVF.

We believe that TTFM seems to be a crucial tool for deciding if a graft is well-functioning or not, and it allows for improvement of graft failure during operation. Our results suggest that detection of graft dysfunction intraoperatively by TTFM improves the surgical outcome.

Background. We retrospectively examined the records of 822 patients who underwent a total of 901 operations for acute peripheral arterial occlusion of the upper or lower extremities between 1999 and 2009. We analyzed the effects of atherosclerotic structure, the time of admission to hospital, and re-embolectomies on amputation in the early postoperative period. Methods. There were 466 (56.7%) men and 356 (43.3%) women. The time of admission to hospital was in the range of 58 hours. There were lower extremity emboli in 683 (83%). Bypass procedures were done in 27 (3.3%) patients. Fasciotomy, patchplasty, and endarterectomy were made in 19 (2.3%), 9 (1.1%), and 7 (0.8%) patients, respectively. Results. Early revision (re-embolectomy) was performed in 77 (9.3%) patients. Amputation was performed in 112 (13.6%) patients. Delay after six hours from the onset of complaints and re-embolectomies increased the risk of amputation and rates. Conclusion. If the embolectomy, which is a rapid and easy technique for treatment of acute arterial emboli, is performed by experienced surgeons without delay, the complications associated with the emboli may be prevented. Otherwise, delayed operation and repeated re-embolizations in acute arterial play important roles in morbidity.

Summary: 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 insuffi ciency. 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.
