Arterial prosthetic graft infection is one of the most challenging issues in vascular surgery. We report a case of an infected descending thoracic aorta endograft, presenting itself several years after placement, with hemoptysis and back pain as referred symptoms. The patient was successfully treated by removing the thoracic aorta and replacing the infected endografts with a cryopreserved aortic allograft, running from the left subclavian artery to the aortic diaphragmatic hiatus.

Comparative Study
Flow characteristics of LIMA radial composite sequential bypass grafting and single LIMA and saphenous vein sequential bypass grafting performed under OPCAB.
The present study was aimed to compare the hemodynamic flow characteristics of LIMA radial artery composite sequential bypass grafting and with single LIMA and saphenous vein sequential bypass grafting performed by off-pump coronary artery bypass grafting (OPCAB). ⋯ The results of the present data suggest the hemodynamic flow characteristics of composite bypass grafting to be inferior to the single LIMA and separate aorta-saphenous vein bypass grafting strategy. However, a longer follow up is warranted to assess the implications of these findings on graft durability.

Multicenter Study
Endovascular management of peripheral arterial trauma in patients presenting in hemorrhagic shock.
This study investigated patients who sustained peripheral arterial trauma, presented with clinical signs of shock, and underwent urgent endovascular repair (endo-R). ⋯ Endo-R of traumatic non-aortic arterial injuries or spontaneous ruptures might be considered as a treatment option-in preference to open repair-even in emergency settings such as in shock patients. However, the safety of endovascular treatment in unstable trauma patients must be proved after comparison with open surgical treatment.

The present study investigates the geometry of failing left ventricles with a special focus on apical deformation. A new surgical remodelling technique is evaluated. ⋯ Apical compression improved ventricular geometry and ventricular function in patients with dialatation of the left ventricular apex.

Randomized Controlled Trial Comparative Study
Effect of postoperative landiolol administration for atrial fibrillation after off pump coronary artery bypass surgery.
Atrial fibrillation is one of the most common postoperative arrhythmias following cardiac surgery. Despite many clinical studies, there is still no consensus on the most appropriate prevention strategy for atrial arrhythmia. A randomized prospective trial was conducted to determine the efficacy of intravenous landiolol administration in the early period after off-pump coronary artery bypass grafting (CABG) followed by treatment with carvedilol for prevention of atrial fibrillation. ⋯ Postoperative intravenous landiolol therapy followed by oral carvedilol may be more effective than oral carvedilol alone for prevention of atrial fibrillation after off-pump CABG. We also found that intravenous landiolol is well tolerated after cardiac surgery.
