    The Last Option Before the Prosthetic Graft in Arteriovenous Fistula Formation: Brachiobasilic Vein Transposition
    (Ortadogu Ad Pres & Publ Co, 2011) Inan, Bekir; Aydin, Unal; Basel, Halil; Erkalp, Kerem; Yasar, Tahsin; Keskin, Siddik
    Objective: Simple arteriovenous fistulas created with cephalic vein provide good vascular access for hemodialysis. Brachiobasilic vein transposition (BBVT) and prosthetic graft (PG) are two alternative methods for vascular access if cephalic vein occlusion have occured. In this study we aimed to compared these two methods and determine the advantages of the procedure. Material and Methods: From June 2006 to April 2009, 83 patients who had undergone BBVT and PG procedures were analyzed retrospectively. The cases were evaluated with their follow up data of 24 months. Trombosis, patency, infection, revision and infection rates were determined with Chi Square and Fischer's Exact tests. Results: No significiant difference was determined between the groups for demographic data and risk factors. However, trombosis (p=0.021), patency (p=0.040), infection (p=0.001) and revision (p=0.001) rates of BBVT group were superior to PG group. Mortality was similar in both groups (p=0.46). Conclusion: BBVT procedure with high patency and low infection rate is an efficient, safe and preferred method for vascular access.

    Outcomes of De Vega Versus Biodegradable Ring Annuloplasty in the Surgical Treatment of Tricuspid Regurgitation (mid-Term Results)
    (Forum Multimedia Publishing, Llc, 2010) Basel, Halil; Aydin, Unal; Kutlu, Hakan; Dostbil, Aysenur; Karadag, Melike; Odabasi, Dolunay; Aydin, Cemalettin
    Purpose: The aim of this study was to compare De Vega semicircular annuloplasty and a new biodegradable ring annuloplasty technique in patients requiring surgical intervention for tricuspid valve disease with concomitant disease of the mitral valve. Methods: Between January 2004 and May 2008, 129 consecutive patients underwent annuloplasty procedures to correct tricuspid valve regurgitation during a concomitant mitral valve operation requiring replacement. Additionally, 24 patients underwent aortic valve replacement (AVR), 11 underwent coronary artery bypass grafting (CABG), 5 underwent AVR plus CABG, 3 underwent mitral valve replacement plus atrial septal defect (ASD) closure, and 2 underwent ASD closure. The patients in this study were assigned to 2 groups: Kalangos ring annuloplasty was performed in 67 patients (group 1), and De Vega semicircular annuloplasty was performed in the remaining 62 patients (group 2). Results: Both tricuspid valve repair techniques produced a low rate of complications; however, the number of patients who developed residual tricuspid regurgitation was significantly lower in group 1. Conclusion: The biodegradable ring annuloplasty technique may be used easily and safely in moderate and severe cases of tricuspid regurgitation; however, larger clinical series are necessary to confirm our promising results.
