Thoracic Endovascular Repair by Chimney Technique for Aortic Dissection with Malperfusion Syndrome / 대한내과학회지

A perfusion deficit of the aortic branch vessels in a patient with a type B aortic dissection is a challenging complication, as it leads to hemodynamic instability and doubles the mortality rate; however, the optimal management strategy in these cases remains controversial. Although surgical repair is still performed as the standard, endovascular approaches have been used recently as alternatives because of the high rate of perioperative complications. Herein, we report a patient with a type B aortic dissection and compromised renal and iliac arteries who was successfully treated by thoracic endovascular repair and insertion of a percutaneous stent. In addition, we adopted the chimney technique to preserve blood flow to the left subclavian artery due to the short proximal landing zone.

Cardiogenic Shock in a Patient with Intermediate Coronary Artery Disease due to Preoperative Spasm / 대한구급학회지

The best management strategy for angiographically intermediated coronary artery diseases remains controversial. Lesions, when coupled with spasm, can lead to catastrophic results and cardiogenic shock. We report a case of a 62-year-old man who had an intermediate coronary artery disease presenting with cardiogenic shock due to coronary spasm during a preoperative period.
