Project description:Superior vena cava laceration has been reported as a catastrophic complication that requires immediate surgical intervention during transvenous lead extraction. Hereby, we present 2 cases of pseudoaneurysm formation at the superior vena cava after transvenous lead extraction, which were successfully managed without invasive treatment. (Level of Difficulty: Advanced.).
Project description:Superior vena cava (SVC) syndrome is an uncommon but serious complication associated with chronic transvenous implanted leads. In the recent past, open-heart surgery combining lead extraction and epicardial implant was usually performed to reduce syndrome recurrences. We describe the case of a 78-year-old man successfully treated by percutaneous lead extraction associated with venous balloon angioplasty and reimplantation of leadless pacemaker. <Learning objective: Chronic vascular complications following lead implantation usually require surgical treatment, due to the need for subsequent epicardial implantation. Percutaneous lead extraction along with leadless pacing allowed effective non-surgical management of chronic complications of transvenous pacing.>.
Project description:A patient with Marfan syndrome undergoing Bentall operation was found to have an absent right superior vena cava and persistent left superior vena cava. The dilation of coronary sinus raised the suspicion of persistent left superior vena cava. The diagnosis was confirmed by agitated saline contrast echocardiography and computed tomography of the chest.
Project description:A patient planned to be performed catheter ablation. However, three-dimensional contrast-enhanced chest computed tomography revealed isolated persistent left superior vena cava. We should know such an anatomical abnormality especially when central venous catheter or peripherally inserted central catheter is inserted from right jugular vein or right subclavian vein.
