A model for delivery of extracorporeal life support in a stand-alone veterans affairs medical center.

INTRODUCTION: For the Veterans Health Administration (VHA) to continue to perform complex cardiothoracic surgery, there must be an established pathway for providing urgent/emergent extracorporeal life support (ECLS). Partnership with a nearby tertiary care center with such expertise may be the most resource-efficient way to provide ECLS services to patients in post-cardiotomy cardiogenic shock or respiratory failure. The goal of this project was to assess the efficiency, safety, and outcomes of surgical patients who required transfer for perioperative ECLS from a single stand-alone Veterans Affairs Medical Center (VAMC) to a separate ECLS center. METHODS: Cohort consisted of all cardiothoracic surgery patients who experienced cardiogenic shock or refractory respiratory failure at the local VAMC requiring urgent or emergent institution of ECLS between 2019 and 2022. The primary outcomes are the safety and timeliness of transport. RESULTS: Mean time from the initial shock call to arrival at the ECLS center was 2.8 h. There were no complications during transfer. Six patients (86%) survived to decannulation. CONCLUSION: These results suggest that complex cardiothoracic surgery can be performed within the VHA system and when there is an indication for ECLS, those services can be safely and effectively provided at an affiliated, properly equipped center.

Solid pseudopapillary tumor of the pancreas.

Solid pseudopapillary tumor is a rare tumor accounting for 1-2% of exocrine neoplasms involving the pancreas. This typically benign tumor is predominately found in young females of non-Caucasian descent between the second and fourth decades of life. Despite the reported increasing incidence of this neoplasm, many physicians are unfamiliar with this tumor, which may lead to uncertainty of diagnosis and treatment. While further delineating the clinical and imaging features of this tumor, we present two cases with review of the literature.

Heartmate 3 Left Ventricular Assist Device Bend Relief Disconnection Causing Laceration of the Outflow Graft.

As technology in mechanical circulatory support continues to advance, so does the utilization of durable left ventricular assist devices (LVADs). We present the first reported case of HeartMate 3 (HM3) LVAD bend relief disconnection causing laceration of the outflow graft. Our patient is a 34 year old male with end-stage heart failure status post-HM3 implantation with recent debridement of a driveline infection who presented with weakness and sanguineous drainage 5 days after an episode of heavy lifting associated with a palpable substernal pop. During the initial evaluation, he experienced sudden massive decompression of a left chest hematoma through a thoracotomy incision with exsanguinating hemorrhage and an abrupt drop in LVAD flow. An emergent anterolateral thoracotomy was performed where it was discovered that the bend relief was disconnected and had lacerated the outflow graft. The graft was repaired and the ring was removed using a diamond blade rotary saw. He was discharged home and made a full recovery. Mechanical device malfunction has been documented in several prior versions of durable LVADS. Although there have been reported cases in the Heartmate 2, this is the first reported case of a HM3 bend relief disconnection and resultant laceration of the outflow graft.
