RESUMEN
BACKGROUND: This study aims to present early and midterm results of vascular reconstruction with saphenous vein panel graft. METHODS: Between August 2014 and August 2017, 11 saphenous vein panel grafts were used for vascular reconstruction in 10 patients. Patient data including age, gender, etiology of the vascular pathology, concomitant injury, site of injury, surgical procedure, additional surgical procedure, and hemodynamic status were retrospectively collected and analyzed. The Kaplan-Meier method was used to calculate the reintervention and patency rates. RESULTS: Mean duration of follow-up was 16.5 ± 13.2 months (ranged, 2-39 months). The freedom from reintervention for any reason was 82% at 1 and 2 years. There was no evidence of arterial claudication or venous insufficiency in all patients. The primary patency rates were 82% at 1 and 2 years. There was no mortality, deep venous thrombosis, pulmonary embolism, graft thrombosis, anastomotic stenosis, diameter discrepancy, and aneurysm formation during late follow-up. CONCLUSIONS: The autologous saphenous panel vein graft enables the surgeon to prepare suitable conduits easily with an appropriate diameter and length for vascular reconstruction. Although long-term results are unknown, this technique provides high patency rates in midterm follow-up, resistance to infection, and low reintervention rates. In conclusion, autologous saphenous vein panel grafts may well be preferred in various vascular disorders that require surgical reconstruction.

PURPOSE: The present study investigated the correlation between extend aortic cross-clamping time and peripheral nerve injury on rats. METHODS: 24 male, Sprague Dawley rats were divided into 3 groups; (a) control group: abdomen was directly closed after reached aorta, and followed by 72 hours, (b) short-term ischaemia-reperfusion group: peripheral nerve ischemia was induced in rats by supraceliac aortic occlusion for 20 min followed by 72 h of reperfusion, (c) long-term ischaemia-reperfusion group: peripheral nerve ischemia was induced for 30 min followed by 72 h of reperfusion. Preoperative and postoperative, electromyography (EMG) recordings were done. End of 72 h, the sciatic nerves were harvested from each animal for histopathological and biochemical analysis. RESULTS: The mean compound muscle action potential (CMAP) amplitude of long-term ischaemia-reperfusion group was statically significant reduced when compared to the control group (p <0.01). However, the mean distal latency value of long-term ischaemia-reperfusion group was statically significant increased (p <0.01). On the other hand, there were statically significant differences between the results of malondialdehyde, edema and ischemia fiber degeneration grades on control and long-term ischaemia-reperfusion group (p <0.001). CONCLUSION: This study demonstrated that the extending cross clamping time directly harms the peripheral nerve of rats.
