Abstract
IntroductionIn resource-poor settings, the modified Blalock-Taussig shunt (MBTS) is often performed for symptomatic relief of Fallot's tetralogy. From September 2011, we adopted the strictly posterior thoracotomy (SPOT), a minimal-access technique for the MBTS and report the cosmetic advantages in this communication.MethodsWe retrospectively analyzed the records of consecutive patients in whom the SPOT approach was used to construct the MBTS. Study end-points were early mortality, improvement in peripheral oxygenation, morbidity, and the cosmetic appeal.ResultsBetween September 2011 and January 2013, 15 males and 8 females, median age 4 years (1.3 - 17 years) and weight 13 kg (11 - 54 kg) underwent the MBTS through the SPOT approach. The polytetrafluoroethylene grafts used ranged from sizes 4 - 6mm (median 5mm). The median preoperative SpO2 was 74% (55% - 78%), increasing to a postoperative median value of 84% (80% - 92%). Shunts were right-sided in 22 patients and left-sided in one. There were no shunt failures. Hospital stay ranged from 7 - 10 days. There was one early death (4.3%), and two postoperative complications (re-exploration for bleeding and readmission for drainage of pleural effusion). The surgical scars had excellent cosmetic appeal: they ranged from 5-10 cm in length; all were entirely posterior and imperceptible to the patient.ConclusionThe SPOT approach represents a safe and cosmetically superior alternative to the standard posterolateral thoracotomy, the scar being imperceptible to the patient. The excellent cosmetic appeal and preservation of body image makes this approach particularly attractive in children and young adults.

In resource-poor settings, the modified Blalock-Taussig shunt (MBTS) is often performed for symptomatic relief of Fallot's tetralogy
On the bases of these concerns, we adopted a strictly posterior thoracotomy (SPOT) for the MBTS beginning from September 2011
Twenty-three patients underwent the MBTS through the SPOT incision of length ranging from 5-10 cm on the basis of body size
Summary
In resource-poor settings, the modified Blalock-Taussig shunt (MBTS) is often performed for symptomatic relief of Fallot's tetralogy. Conclusion: The SPOT approach represents a safe and cosmetically superior alternative to the standard posterolateral thoracotomy, the scar being imperceptible to the patient. The modified Blalock-Taussig shunt (MBTS) is performed for symptomatic relief of Fallot's tetralogy in patients unable to afford the out-of-pocket expense for primary complete correction. The original approach for the modified Blalock-Taussig shunt (MBTS) as described by de Leval and coworkers [3] was a posterolateral thoracotomy. The posterolateral thoracotomy has been associated with musculoskeletal deformities, especially in children with congenital heart defects [5] and the resulting scar affected the choice of clothing and/or caused embarrassment in 56% of patients in another study [6]. To the best of our knowledge, this minimal-access approach has not been reported for the construction of the MBTS
