A lung spreader, assembled from disused devices, used in coronary artery revascularization is presented. More than 25 years ago, the use of a malleable lung spreader was proposed to facilitate the internal thoracic artery dissection especially its proximal segment, but that device has never been manufactured. Palabras clave: Revascularización miocárdica, Arteria torácica interna, Cavidad pleural, Neumotórax, Enfermedad pulmonar obstructiva crónicaĪBSTRACT Internal thoracic artery dissection is one of the most defining procedures of coronary artery bypass grafting, as it has been demonstrated that the quality of life and short-long term outcome of patients will depend on the morphological characteristics of the graft. Se comentan y discuten las principales ventajas demostradas durante más de tres años en cerca de un centenar de pacientes. Se presenta un separador pulmonar manufacturado a partir de dispositivos en desuso, empleados en cirugía coronaria. Hace más de 25 años se propuso la utilización de un separador pulmonar maleable para facilitar la disección de la arteria torácica interna, especialmente su segmento proximal, pero nunca se ha fabricado ese dispositivo. RESUMEN La disección de la arteria torácica interna es uno de los procedimientos más defi-nitorios de la cirugía de revascularización miocárdica, pues se ha demostrado que la calidad de vida y la evolución a corto y largo plazo de los pacientes dependerán de las características morfológicas del injerto. In conclusion, the limited evidence base prevents robust informed decision-making when comparing both techniques. This review suggests that semi-skeletonized harvesting could possibly be associated with favourable outcomes when compared to pedicled harvesting with respect to graft length and flow, and lower postoperative bleeding, without increasing operative time although there is insufficient data to compare sternal wound infections or long-term outcomes. No studies reported a statistically significant difference in operative time.

One randomized controlled trial and 3 cohort studies reported that semi-skeletonized harvesting reduced postoperative bleeding. Three studies included data on surgical wound infections/mediastinitis, all of which reported n = 0. One randomized controlled trial showed superiority with semi-skeletonized harvesting in terms of conduit length (P < 0.001), flow (P = 0.004) and diastolic filling (P = 0.005). The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Three studies were cohort studies and 2 were randomized controlled trials. Altogether, 235 papers were found using the reported search, of which 5 represented the best evidence to answer the clinical question.

The question addressed was, ‘in patients undergoing coronary artery bypass grafting is semi-skeletonized harvesting superior to pedicled harvesting of the left internal mammary artery (LIMA) in terms of conduit length, flow, rate of sternal wound infections and post-operative bleeding?’.

In this review article, we aimed to discuss and analyze all these techniques of harvesting and preparing ITAs with the help of literature to find the best way for ITAs harvesting and preparation for myocardial revascularization.Ī best evidence topic in cardiac surgery was written according to a structured protocol. However, the single standard method for harvesting and preparation of ITAs has yet to be determined.

Access and harvesting through median sternotomy, mini anterolateral thoracotomy, thoracoscopic, and robotic-assisted harvesting of ITAs are the different techniques used in clinical practice. At the same time, access to the ITAs for harvesting has also been studied. Harvesting of ITAs in pedicled or skeletonized fashion, with electrocautery or harmonic scalpel, with open or intact pleura, with clipping the end or keeping it perfused papaverine delivery with intraluminal injection, perivascular injection, injecting into endothoracic fascia, and papaverine topical spray are the different techniques introduced by the number of researchers. Over the last few decades, various methods and techniques for ITAs harvesting have been introduced by different surgeons and applied in clinical practice with different results. Harvesting and preparation of ITAs for revascularization is a technically demanding procedure with multiple challenges. Internal thoracic arteries (ITAs) are the gold standard conduits for coronary revascularization because of their long-term patency and anti-atherosclerotic properties.
