Published: January 2021

Congenital abdominal aortic aneurysms (AAA) are an extremely rare entity. We present the case of a female fetus diagnosed with an AAA on routine prenatal ultrasound. A postnatal computed tomography angiogram revealed an infrarenal AAA with a narrow proximal neck. Surgery was performed on day of life 14 using a cadaveric femoral artery graft. The proximal anastomosis was performed under the microscope given the severity of the aortic stenosis and the proximity of the renal arteries. The patient's postoperative course was uneventful and she is developing normally 1 year after surgery. The graft remains permeable, albeit with evidence of proximal and distal stenosis and graft calcification on imaging.

Necrotizing enterocolitis (NEC) is a devastating illness with mortality rates approaching 26 ​%, with 4 ​% of patients with congenital heart disease (CHD) receiving this diagnosis. In this retrospective cohort study, the Pediatric Health Information System database was used to compare outcomes among patients with NEC diagnoses between 2019 and 2021 by CHD. The association of clinical factors with the outcomes of interest were compared using multivariable logistic regression.

Hematological disorders such as afibrinogenemia are reported to cause bleeding disorders mostly cerebral hemorrhage. Despite being a life-threatening condition, data about spontaneous splenic rupture in patients with Afibrinogenemia remain scarce.

Vascularized composite allograft deceased donation in the United States.

Front Transplant

January 2025

Organ Donation Services, New England Donor Services, Waltham, MA, United States.

Vascularized composite allograft (VCA) transplantation represents a significant advancement in reconstructive surgery and offers hope to individuals who experienced congenital disorders or severe tissue injuries to restore physical appearance, function, and enhance quality of life. VCA recovery introduces complexities to conventional solid organ recovery, and there remain concerns regarding the potential impact of VCA recovery on non-VCA organs for transplant. The current retrospective study examines deceased donor characteristics and observed-to-expected (O/E) organ yield ratios for 51 VCA donors recovered in the US between July 4, 2014 and March 31, 2024, compared with a contemporary cohort of non-VCA donors recovered in 2023.
