    Anesthesia Management with Ultrasound Guided Thoracic Paravertebral Block for Donor Nephrectomy: A Prospective Randomized Study
    (2017) Yenidunya, Ozlem; Bircan, Huseyin Yuce; Altun, Dilek; Caymaz, Ismail; Demirag, Alp; Turkoz, Ayda; 28235492; AAR-7467-2020; R-6394-2019
    Study objective: To determine the efficacy of ultrasound-guided thoracic paravertebral block intraoperatively and 24 hours postoperatively in patients undergoing donor nephrectomy. Design: Prospective randomized controlled study. Setting: Private foundation university hospital; November 2014 to June 2015. Patients: Thirty-two patients undergoing donor nephrectomy (exclusion criteria: coagulation disorders, allergy to local anesthetics, and unwillingness to participate). The final study population comprised 30 patients (15 male, 15 female) randomly assigned to either Group P (paravertebral block, n = 14) or Group M (morphine, n = 16). Interventions: In Group P, a unilateral paravertebral catheter was inserted 1 day preoperatively; on the day of surgery, a single-level unilateral paravertebral block was administered through the catheter before general anesthesia. Infusion of bupivacaine continued intraoperatively and postoperatively. Patients in Group M received only general anesthesia, and morphine patient-controlled analgesia was begun postoperatively. Measurements: Intraoperative analgesic and anesthetic requirement, postoperative numerical rating scale pain scores, additional analgesic consumption during the postoperative period, and incidence of complications related to thoracic paravertebral block (TPVB) like pleural puncture, pneumothorax, epidural spread, injection into the subarachnoid space, intravascular injection, and Homer's syndrome and rate of opioid related adverse reactions like nausea and vomiting, itching, constipation, and respiratory depression. Results: Intraoperative remifentanil consumption was significantly higher in Group M, and postoperative morphine consumption was significantly lower in Group P (P <.001). During the first 24 hours postoperatively, the mean numerical rating scale pain scores were similar and there were no significant differences between the 2 groups. There were no statistically significant differences in the additional analgesic consumption and rate of adverse reactions between the 2 groups. We didn't detect any complication related to TPVB in group P. Conclusions: Continuous thoracic paravertebral block provides good intraoperative stability with a low anesthetic requirement and reduces postoperative morphine consumption for up to 24 hours. Ultrasound guided technique enhanced the safety of TPVB and provides analgesia without major complications. (C) 2016 Elsevier Inc. All rights reserved.

    Targeted endovenous treatment of Giacomini vein insufficiency-associated varicose disease: considering the reflux patterns
    (2014) Atasoy, Mehmet Mahir; Gumus, Burcak; Caymaz, Ismail; Oguzkurt, Levent; 25205026
    PURPOSE We aimed to assess the technical feasibility of targeted endovenous treatment of Giacomini vein insufficiency (GVI)-associated varicose disease and report our early results. METHODS We retrospectively screened 335 patients with varicose disease who underwent endovenous laser ablation from September 2011 to January 2013, and determined 17 patients who underwent Giacomini vein ablation. Using a targeted endovenous treatment approach considering the reflux pattern, all healthy great saphenous veins (GSV) or vein segments were preserved while all insufficient veins (Giacomini vein, perforator veins, small saphenous vein, anterior accessory GSV, major tributary veins, or incompetent segments of the GSV) were ablated. Treatment success was analysed using Doppler findings and clinical assessment scores before and after treatment. RESULTS Targeted endovenous treatment was technically successful in all cases. Seven GSVs were preserved totally and three GSVs were preserved partially (10/17, 58%), with no major complications. Clinical assessment scores and Doppler findings were improved in all cases. CONCLUSION Targeted endovenous treatment of GVI-associated varicose disease is safe and effective. In majority of GVI cases saphenous vein can be preserved using this approach.
