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.

BackgroundAccording to some reports, left hemidiaphragmatic paralysis due to phrenic nerve injury may occur following cardiac surgery. The purpose of this study was to document the effects on phrenic nerve injury of whole body hypothermia, use of ice-slush around the heart and mammary artery harvesting.MethodsElectrophysiology of phrenic nerves was studied bilaterally in 78 subjects before and three weeks after cardiac or peripheral vascular surgery. In 49 patients, coronary artery bypass grafting (CABG) and heart valve replacement with moderate hypothermic (mean 28°C) cardiopulmonary bypass (CPB) were performed. In the other 29, CABG with beating heart was performed, or, in several cases, peripheral vascular surgery with normothermia.ResultsIn all patients, measurements of bilateral phrenic nerve function were within normal limits before surgery. Three weeks after surgery, left phrenic nerve function was absent in five patients in the CPB and hypothermia group (3 in CABG and 2 in valve replacement). No phrenic nerve dysfunction was observed after surgery in the CABG with beating heart (no CPB) or the peripheral vascular groups. Except in the five patients with left phrenic nerve paralysis, mean phrenic nerve conduction latency time (ms) and amplitude (mV) did not differ statistically before and after surgery in either group (p > 0.05).ConclusionsOur results indicate that CPB with hypothermia and local ice-slush application around the heart play a role in phrenic nerve injury following cardiac surgery. Furthermore, phrenic nerve injury during cardiac surgery occurred in 10.2 % of our patients (CABG with CPB plus valve surgery).

Temporary AV fistula and free flap may provide stable wound coverage and high rate of limb salvage in treatment of diabetic foot ulcers with large tissue loss.

Klippel-Trenaunay syndrome (KTS) manifests cutaneous vascular nevus, superficial venous varicosities, and hypertrophy of the affected limb. KTS may be associated with other developmental anomalies such as polydactyly, syndactyly, and macrocephaly. We present a case with KTS associated with polydactyly.

There are no reports in the literature of routine preoperative and postoperative electrophysiological studies in large patient groups to evaluate brachial plexus injury during open heart surgery. It is known that heart surgery sometimes causes partial brachial plexus injury, especially in the lower trunk. However, these peripheral nerve problems are usually not considered clinically important and are not investigated. Patients undergoing open heart surgery must be closely followed up for peripheral nerve injury during the postoperative period.
