“…As only 5% of the resistance of the system is in the upstream segment of the microcirculation, the radius of the graft is of little relevance. This is in accordance with the findings of Nordgaard et al [6], which showed that the flow of sequential grafts is significantly higher than in isolated grafts and explains why the literature includes studies that show that the sequential grafts are equivalent [7][8][9][10][11] or better [12,13] than isolated grafts .…”

We would like you to participate in this meeting as our guest speaker and present your recent work and ideas of "Postoperative mediastinitis in cardiovascular surgery postoperation. Analysis of 1038 consecutive surgeries" that were published in Rev Bras Cir Cardiovasc 25.1 [1]. This is one of the high profile and interesting studies we wish to invite to our meeting and we hope it will have benefit to you as well as to our growing scientific community.

“…After March 2003, the off-pump surgery was performed in 11 out of 19 cases (57%). RA was harvested with a no-touch technique and with no mechanical expansion before implantation [ 10 ] . After harvesting, the graft was left in situ with topic papaverine until the initialization of coronary grafting.…”

Introduction Left internal thoracic artery to left anterior descending artery (LITA-LADA) grafting has become a fundamental part of coronary artery bypass grafting (CABG). This grafting has led to an increased use of other arterial conduits, of which the radial artery (RA) is the most popular. Whether RA can have the same long-term patency as LITA is controversial. The objective of this study is to access the long-term clinical follow-up and, when available, the patency rate of RA grafts. Methods Twenty-six patients from a previous study with critical stenosis in all target vessels underwent complete arterial CABG with LITA and RA grafts from 1996 to 2003. They all underwent midterm multidetector computed tomography after surgery with the association of at least one patent LITA and one patent RA graft. Results Twelve patients (46%) are alive with no angina symptoms. Six patients underwent a second image exam 12 to 16 years (average of 14 years) after surgery, with a total of six LITA-LADA and 14 RA grafts with 100% patency rate. Clinical follow-up five to 23 years after surgery (average of 14 years) showed only one death 12 years after surgery related to coronary artery disease (CAD) (3,8%). Another 12 patients died of non-CAD. Conclusion Patients with midterm associated LITA and RA patent grafts show similar optimal long-term patency rates of both types of grafts with excellent clinical outcome.

“…The graft of radial artery (RA) and saphenous vein (SV) with sequential anastomoses for DB showed to be superior than their respective isolated grafts for this branch [5,7]. Our group reported that the LITA and RA used isolatedly or sequentially show similar results [8,9].…”

Análise angiográfica tardia dos enxertos empregados na revascularização miocárdica de pacientes com retorno de sintomasCABG late angiographic grafting patency analysis in patients with recurrent symptoms Abstract Objective: Left internal thoracic artery (LITA) grafting has become essential in coronary artery bypass graft procedure (CABG). In order to optimize the use of LITA or other grats, sequential anastomosis has been used. There is no consensus on equivalence between isolated versus sequential grafts. The aim of this study is to compare isolated versus sequential grafts.Methods: From a retrospective patency analysis of the grafts used in 88 symptomatic patients who underwent CABG procedure in our Service was performed through cinecoronariography. Statistical analysis was performed through Student's t test. Each distal anastomosis was considered an independent graft.Results: The mean postoperative period was of 53 + 138 months and mean age was 64 + 11 years. LITA isolated grafts presented patency rate significantly higher than the sequential grafts, respectively 92% (46/50) and 77% (30/39) P = 0.02. However, in injured coronary arteries of > 70%, isolated LITA patency rate was similar to sequential grafts, (95%; 37/39) and (93%; 26/28) respectively; P = 0.37. Mean radial artery patency rate was similar to isolated 71% (5/7) and sequential 90% (19/21) grafts; P = 0. Saphenous veinThis study was carried out at the Paulo Sacramento Hospital. patency rates were similar for isolated 72% (31/43) and sequential 81% (73/90) grafts; P = 0.12. There was no difference between radial artery and saphenous vein patency rates.Conclusion: In symptomatic patients, isolated LITA patency is superior than sequential LITA. However, in coronary injuries of > 70%, the isolated and sequential patency rates are similar. Sequential grafts from radial artery and saphenous vein are similar to their respective isolated grafts.

Resumo Objetivo: A Artéria Torácica Interna Esquerda (ATIE) é o padrão ouro como enxerto na revascularização miocárdica (RM). Para otimizar seu uso, e de outros enxertos, têm sido usadas anastomoses sequenciais. Não há consenso da equivalência dos resultados entre enxertos isolados e sequenciais. O objetivo é comparar a perviabilidade dos enxertos isolados versus sequenciais. 139ROCHA E SILVA, R ET AL -CABG late angiographic grafting patency analysis in patients with recurrent symptoms Bras Cir Cardiovasc 2009; 24(2): 138-142 Rev
