ABSTRACT
Internal thoracic artery aneurysms (ITAAs) are rare with wide variation in clinical presentation and a high risk of rupture. Endovascular techniques are increasingly being used for treatment of such aneurysms over surgical repair in recent times. A 34-year-old male presented with progressive swelling of the right anterior chest wall for 2 weeks and was diagnosed with right internal thoracic artery aneurysm with contained rupture. He underwent successful endovascular repair with coil embolization of ruptured right ITAA. Post intervention computed tomography (CT) angiography confirmed sealing of the ruptured aneurysm with no residual filling of the sac. At six months follow-up he is doing well with complete resolution of hematoma. This case demonstrates that an endovascular approach with coil embolization is a feasible and safe option for treating the rare ruptured ITAAs.
Os aneurismas da artéria torácica interna (ITAAs) são raros, com ampla variação na apresentação clínica e alto risco de ruptura. As técnicas endovasculares têm sido cada vez mais utilizadas para o tratamento desses aneurismas em relação ao reparo cirúrgico. Um homem de 34 anos de idade apresentou edema progressivo da parede torácica anterior direita por 2 semanas e foi diagnosticado com aneurisma da artéria mamária interna direita com ruptura contida. Ele foi submetido a reparo endovascular bem-sucedido, com embolização de ITAA direito roto. A angiotomografia computadorizada (angioTC) pós-intervenção confirmou o selamento do aneurisma rompido, sem enchimento residual do saco. No seguimento de 6 meses, ele estava bem, com resolução completa do hematoma.

BACKGROUND: Different techniques have been described for percutaneous Achilles tendon rupture repair, but no biomechanical evaluation has been performed separately for proximal and distal suturing techniques. The purpose of this study was to biomechanically analyze proximal versus distal percutaneous Achilles suture configurations during cyclic loading and load to failure. METHODS: A simulated, midsubstance rupture was created 6 cm proximal to the calcaneal insertion in fresh-frozen cadaveric Achilles tendons. Fifteen proximal specimens were divided into 3 groups: (A1) triple locking technique, (A2) Bunnell-type technique, and (A3) double Bunnell-type technique. Twelve distal specimens were divided into 2 groups: (B1) triple nonlocking technique and (B2) oblique technique. Repairs were subjected to cyclic testing and load to failure. Load to failure, cause of failure, and tendon elongation were evaluated. RESULTS: None of the proximal specimens and 7/12 of the distal ones failed in cyclic testing. The proximal fixation groups demonstrated significantly more strength than the distal groups (P = .001), achieving up to 710 N of failure load in Group A3. Groups B1and B2 failed on average at 380 N with no difference between them (P > .05). The majority of all repairs failed in the suture-tendon interface. Distal groups had more elongation during cyclic testing (13.7 mm) than proximal groups (9.4 mm) (P = .02). CONCLUSION: The distal fixation site in this Achilles tendon repair was significantly weaker than the proximal fixation site. A proximal modified suture configuration increased resistance to cyclic loading and load to failure significantly. CLINICAL RELEVANCE: A modification can be suggested to improve strength of the Achilles repair.

Introducción: La reparación quirúrgica puede realizarse mediante cirugía abierta o por técnicas mínimamente invasivas. La técnica percutánea combina las ventajas del tratamiento quirúrgico abierto con el tratamiento ortopédico. El objetivo de este trabajo es comparar la técnica mínimamente invasiva de Dresden descrita por Amlang con la cirugía abierta convencional. Materiales y Métodos: Entre marzo de 2010 y septiembre de 2013, 45 pacientes fueron operados, 15 casos con técnica abierta convencional y 15 casos con la técnica percutánea de Dresden. Se dividió a los pacientes en dos grupos según el método quirúrgico utilizado y, luego, se analizaron comparativamente los resultados. El criterio de elección del método quirúrgico fue al azar, siempre que se realizara dentro de los siete días de la rotura. Resultados: Se mencionan los resultados comparativos del tiempo quirúrgico, el trofismo, la longitud de la cicatriz, la diferencia comparativa en el perímetro del gemelo. El puntaje de la AOFAS a los 5 meses fue 90 para el grupo A y 95 para el grupo B. Tiempo promedio de retorno a la actividad laboral: grupo A, 7 meses; grupo B, 3.53 meses. Media del retorno a la actividad deportiva: grupo A, 12.22 meses; grupo B, 6.53 meses. Conclusiones: La reparación percutánea de Dresden es una buena opción para las roturas del tendón de Aquiles; la evolución clínico-funcional es buena y se minimizan los riesgos de otra rotura y lesiones del nervio sural.
Introduction: Surgical repair can be performed by open or minimally invasive surgery techniques. The percutaneous technique combines the advantages of the open treatment with orthopedic surgery. The aim of this study is to compare minimally invasive Dresden technique described by Amlang with conventional open surgery. Methods: Between March 2010 and September 2013, 45 patients were surgically treated using conventional open surgery (15 cases) or percutaneous Dresden technique (15 cases). Patients were divided into two groups according to the surgical method used and then the results were comparatively analyzed. Surgical method was selected at random, provided that it was performed within 7 days after rupture. Results: Comparative results of surgical time, muscle trophism, length of scar, and comparative difference in the twin perimeter calf are reported. AOFAS score at 5 months: 90 in group A and 95 in group B. Average time to return to work: group A, 7 months; group B, 3.53 months. Mean time to return to sport activity: group A, 12.22 months; group B, 6.53 months. Conclusions: Dresden technique is a good option for Achilles tendon ruptures; with good clinical and functional outcome minimizing the risk of rupture and sural nerve injury.
