Vertebral compression fractures (VCFs) may result in a kyphotic deformity which can cause potential systemic complications secondary to respiratory and gastrointestinal dysfunction. The use of implants in the spine for VCF treatment represents a paradigm shift away from cement injection on its own, aiming to combine the analgesic and stabilizing effect of injecting cement into the vertebral body with vertebral height restoration and kyphotic angle correction. Spine implants which can be used for VCF treatment include stents, jacks, PEEK cages and fracture reduction systems...

Intra-abdominal injury is an uncommon complication of chest tube insertion. A 66-year-old man had empyema and underwent chest tube insertion for drainage. Massive hemorrhage occurred; the postprocedural radiograph showed the malpositioned chest tube in the mediastinum. Computed tomography scan showed that the tube's tip penetrated through the liver capsule and passed through the hepatic vein to the right ventricle. Hepatic tract embolization with coiling was performed during chest tube removal under a controlled condition with the hepatic tract occluded by a balloon catheter...

Branched thoracic aortic aneurysm repair requires arterial access from above the diaphragm in order to insert the visceral branches. This is routinely performed from the subclavian, axillary or carotid arteries and less commonly direct thoracic aorta puncture. The left ventricular apex is an alternative access route which is commonly used for percutaneous aortic valve replacement and rarely used for EVAR, FEVAR and TEVAR access. Here we describe two patients for which the left ventricular apex was the most suitable available access to the visceral branches during a branched thoracic aortic aneurysm repair...

Resection of the inferior vena cava (IVC) is a rare surgical technique that is occasionally combined with nephrectomy in the setting of renal malignancy with intravascular tumor extension. While this may be fairly well tolerated in some patients due to extensive collateralization in the venous system, there is a clear potential for lower extremity venous insufficiency and deep vein thrombosis (DVT). This report describes a patient who underwent right nephrectomy and segmental IVC resection from the subhepatic space to the iliac confluence, which was complicated by profoundly symptomatic lower extremity DVT and gastrointestinal hemorrhage due to system-to-portal shunting...
