Clinical application and strategy of total-arterial coronary artery bypass grafting / 中国胸心血管外科临床杂志

@#Since the advent of coronary artery bypass grafting (CABG), the selection of bypass conduits has always been one of the most controversial topics in this field. Arterial conduits have received extensive attention due to their excellent biological features and high patency. In recent years, the application of arterial grafting and total arterial grafting in China keeps increasing in recent years, but there is still a gap compared to the Europe and America. Previous clinical studies have indicated the benefits of the total arterial grafting in terms of patency and long-term outcomes, but the advantage of multiple arterial grafting over other procedures is still in need to be confirmed with high-quality randomized controlled trials. This article reviews the clinical application and strategy of total-arterial CABG, aiming to provide objective reference for future clinical research and application.

A dedicated stitch to allow early safe mobilization avoiding drain-induced heart injury

Abstract Placement of a mediastinal drain is a routine procedure following heart surgery. Postoperative bed rest is often imposed due to the fear of potential risk of drain displacement and cardiac injury. We developed an encapsulating stitch as a feasible, effective and low-cost technique, which does not require advanced surgical skills for placement. This simple, novel approach compartmentalizes the drain allowing for safe early mobilization following cardiac surgery.

Elective vs non-elective radial artery grafts: comparing midterm results through 64-Slice computed tomography

BACKGROUND: Left internal thoracic artery to left anterior descending artery (LITA-LADA) grafting has become a fundamental part of the coronary artery bypass graft procedure (CABG). This grafting in turn has led to an increased use of other arterial conduits, of which the radial artery (RA) is most popular. Whether RA grafting can be used in the emergency patient is controversial. METHODS: 47 patients with critical stenosis (>70 percent) in all target vessels underwent CABG with LITA and RA grafts from 1996 to 2003. Patients were divided into elective (23 patients) and non-elective groups (24 patients) with LITA and RA grafts per patient being similar in both groups. Of these 47 patients, 5 died from non-cardiac complications and 12 were unavailable. Thus, 30 patients (71 percent of survivors) were studied by multidetector computed tomography. A total of 36 LITA and 64 RA grafts were studied. RESULTS: The RA patency rate for elective and non-elective grafts were 82 percent (31/38) and 85 percent (22/26), respectively (p=0.75). The RA had a similar patency rate for all target vessels ranging from 73 percent to 100 percent. Only one patient had a redo CABG and 29 (97 percent) are free from angina or re-intervention. LITA-LADA had a 92 percent (11/12) and 100 percent (10/10) patency rate for elective and non-elective groups, respectively (p=0.37). The sequential LITA-diagonal-LADA in the elective group had a 50 percent (03/06) patency rate, which was significantly lower than the 100 percent (08/08) patency rate of the non-elective group (p=0.02). CONCLUSION: Radial Artery grafts can be used in both elective and non-elective patients with excellent results.

INTRODUÇÃO: A anastomose da artéria torácica interna esquerda com a artéria descendente anterior (ATIE-DA) se tornou parte fundamental da cirurgia de revascularização do miocárdio (RM). Esta técnica levou ao aumento de utilização de outros enxertos arteriais, entre os quais, a artéria radial (AR) é muito usasa. Na literatura há controvérsia se a AR pode ser usada em pacientes em RM de emergência. MÉTODOS: 47 pacientes com lesões críticas (>70 por cento) em todas as artérias alvo foram submetidos à RM com ATIE e a AR entre 1996 e 2003. Os pacientes foram agrupados em eletivos (23 pacientes) e não eletivos (24 pacientes) sendo similares para número de enxertos de ATIE e AR por paciente. Dos 47 pacientes, 5 morreram de complicações não cardíacas e 12 não estavam disponíveis. Portanto, 30 pacientes (71 por cento dos sobreviventes) foram estudados com tomografia computadorizada. Um total de 36 ATIE e 64 AR foram analisadas. RESULTADOS: a perviabilidade da AR nos grupos eletivo e não eletivo foram respectivamente 82 por cento (31/38) e 85 por cento (22/26) (p=0,75). A AR teve perviabilidade semelhante para todas as artérias alvo variando de 73 por cento a 100 por cento. Apenas um paciente foi submetido à nova RM e 29 (97 por cento) estão livres de angina ou nova re-intervenção. ATIE-DA teve perviabilidade de 92 por cento (11/12) e 100 por cento (10/10) respectivamente nos grupos eletivo e não-eletivo (p=0,37). ATIE-Diagonal-DA seqüencial obteve perviabilidade de 50 por cento (03/06) no grupo eletivo que foi significativamente menor que a perviabilidade de 100 por cento (08/08) do não-eletivo (p=0,02). CONCLUSÃO: A AR pode ser utilizada nos pacientes eletivos e não eletivos com excelentes resultados.
