Case ReportsLeft ventricular decompression on Veno-arterial extracorporeal membrane oxygenation with intra-aortic balloon Counterpulsation.
Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) has been used increasingly to support patients with cardiogenic shock (CS). There has been growing recognition of the favorable and unfavorable hemodynamic effects of this therapy and recent interest in the use of other percutaneous circulatory support devices to offset some of the potentially harmful hemodynamic effects. Herein, we provide visual evidence of the effects of intra-aortic balloon pump (IABP) counterpulsation for a patient with peripheral VA-ECMO cannulation. ⋯ This case visually demonstrates effective LV decompression by IABP counterpulsation in VA-ECMO support. While the overall effects of LV decompression in patients on VA-ECMO with IABP are still unclear, this report demonstrates one potential mechanism of benefit in the prevention of stagnation of blood flow that may lead to intra-cardiac or aortic root thrombus formation.

Computed tomography-guided preoperative semi-rigid hook-wire localization of small pulmonary nodules: 74 cases report.
The study aimed to retrospectively evaluate the success rate, utility, practicality and results of pre-operative CT (computed tomography)-guided semi-rigid single hook-wire placement and the pathology results of small pulmonary nodules (SPN). ⋯ Preoperative localization of small pulmonary nodules using semi-rigid single hook wire was found to be practical and safe, which allows for proper diagnosis. Incidental small pulmonary nodule, especially GGO larger than 10 mm needs to be taken seriously.
