Virtual Imaging for a Complex Case of Previous Coarctation Repair.

Repeated surgical procedures for previous aortic coarctation is challenging. Three-dimensional imaging may be useful to visualize the complex anatomy more clearly than with computed tomography imaging, possibly leading to better outcomes. To evaluate the feasibility and efficacy of virtual imaging for preoperative planning of thoracic aortic surgery in this case, we used Vesalius 3D software, 3-dimensional image processing software, and detailed anatomic exploration.

Hybrid repair of complex aortic arch disease typically requires aortic debranching to create a proximal landing zone for completion arch endografting. Despite advances in endograft technology, physician-modified endografting may be required to customize a prosthesis for challenging anatomy. We present a case of a complex distal arch aneurysm after a prior coarctation repair with a pediatric interposition graft several decades earlier, treated with hybrid repair by double transposition for arch debranching and physician-modified arch endografting for complete aneurysm exclusion.

Herein, we describe a 21-month-old girl with PHACE syndrome (posterior fossa hemangiomas, arterial lesions, cardiac anomalies/coarctation of the aorta, and eye anomalies) who presented with a tortuous extensive aortic arch aneurysm. As the maximum short diameter of the distal aortic arch aneurysm expanded rapidly from 21 mm to 25 mm in only 5 months, we performed extensive aortic arch reconstruction with interposition graft replacement through a left thoracotomy under partial cardiopulmonary bypass.

Purpose: To correct maternal breathing and fetal bulk motion during fetal 4D flow MRI.
Methods: A Doppler-ultrasound fetal cardiac-gated free-running 4D flow acquisition was corrected post hoc for maternal respiratory and fetal bulk motion in separate automated steps, with optional manual intervention to assess and limit fetal motion artifacts. Compressed-sensing reconstruction with a data outlier rejection algorithm was adapted from previous work.

Managing an adult patient with aortic coarctation and associated anomalies presents a significant surgical challenge. We present a case of an adult male with aortic coarctation, pre-coarctation distal arch 7-cm aneurysm involving the origin of the left subclavian artery, and aberrant (lusoria) right subclavian artery. He was managed with one surgical approach, consisting of right carotid-subclavian bypass, exclusion of the right subclavian artery, proximal descending aortic replacement and reinsertion of left subclavian artery, using partial cardiopulmonary bypass.
