Purpose: A left axillary artery perfusion instead of a femoral perfusion has the benefit of avoiding false lumen perfusion and atheroembolization into the brain, which is caused by retrograde perfusion in type A aortic dissection surgery. We performed type A aortic dissection surgery using the left axillary artery perfusion technique and reviewed this method.
Patients And Methods: From April 2002 to January 2004, 8 patients with a mean age of 70 years (48 to 81), underwent axillary artery cannulation with a side graft technique in type A aortic dissection operations. Six patients had acute type A and 2 had chronic type A dissections. The surgical procedures were ascending aortic replacement in 5, hemiarch replacement in 2, and total arch replacement in 1.
Results: In all patients, a cardiopulmonary bypass was established through the left axillary perfusion. There were no operative deaths and no hospital deaths. All patients were able to avoid cerebral vascular accidents. One patient required a femoro-femoro bypass on the 10th postoperative day because of malperfusion of the left leg, which occurred suddenly. Postoperative hemorrhaging requiring resternotomy occurred in 2 patients.
Conclusion: A left axillary artery perfusion is safe and useful for arterial inflow for type A aortic dissection surgery.

Occult breast cancer (OBC) is a relatively rare clinical condition that can complicate differential diagnosis efforts and delay the administration of specific treatments. The individualized therapy of patients with OBC should be performed based on their clinical symptoms, imaging findings and pathological diagnosis. The present case study describes a 51-year-old woman with a painless left axillary tumor.

Many institutions perform thoracoscopic surgery for pediatric extrapulmonary sequestration (EPS). This approach achieves good cosmetic outcomes due to the small skin incision in comparison to open surgery. However, an extension or additional incision is sometimes necessary to extract resected specimens from the thoracic cavity, which reduces the advantages of this procedure.

The use of temporary left ventricular assist devices (tLVADs) for patients suffering from cardiogenic shock (CS) is becoming more common. This study examines the indications and outcomes of microaxial flow pumps (Impella, Abiomed Inc., Danvers, MA, USA) when cannulated through the axillary artery in patients with severe CS, with a particular focus on acute phase reactions and hemolytic responses.
