“…Most of these AAAs ultimately require an operation, yet rare cases of spontaneous resolution may occur, probably by aneurysmal thrombosis. 37 There must be no active infection if the intended surgical intervention includes placement of a prosthetic graft. Unfortunately, such an option does not exist in the case of an acutely expanding or ruptured AAA.…”

“…Umbilical artery catheterization is associated with significant complications such as thrombosis and thromboembolism, which occur either from a blood clot or air in the infusion system [ 8 ]. Umbilical arterial catheterization-induced abdominal aortic thrombosis can cause necrotizing enterocolitis [ 42 ], congestive heart failure [ 43 ], mycotic aortic aneurysm [ 44 ], multiple aortic aneurysms, and aortic pseudoaneurysms [ 45 , 46 ]. As aortic thrombosis is a common complication of UAC insertion, it has been recommended that any infant who experiences UAC insertion should be screened for abdominal aortic thrombosis upon UAC removal [ 47 ].…”

About 10% of newborns require some degree of assistance to begin their breathing, and 1% necessitates extensive resuscitation. Sick neonates are exposed to a number of invasive life-saving procedures as part of their management, either for investigation or for treatment. In order to support the neonates with the maximum possible benefits and reduce iatrogenic morbidity, health-care providers performing these procedures must be familiar with their indications, measurements, and potential complications. Hence, the aim of this review is to summarise ten of the main neonatal intensive care procedures with highlighting of their indications, measurements, and complications. They include the umbilical venous and arterial catheterizations and the intraosseous line which represent the principal postnatal emergency vascular accesses; the peripherally inserted central catheter for long-term venous access; the endotracheal tube and laryngeal mask airway for airway control and ventilation; chest tube for drainage of air and fluid from the thorax; and the nasogastric/orogastric tube for enteral feeding. Furthermore, lumber puncture and heel stick were included in this review as very important and frequently performed diagnostic procedures in the neonatal intensive care unit.

Background Umbilical artery catheter (UAC) use is common in the management of critically ill neonates; however, little information exists regarding the anatomic and vascular effects of UAC placement in premature newborns. Methods and Results Baboons were delivered at 125 d of gestation (term = 185 d), treated with surfactant, had UACs placed, and were ventilated for either 6 d or 14 d. Animals were assigned to short-term (6 d, n = 6) and long-term (14 d, n = 30) UAC placement. At necropsy, aortas were removed with UACs still in place. Histological examination of upper, middle, and lower aorta specimens stained with hematoxylin and eosin and immunolabelled to detect smooth muscle (α-actin) was done in a blinded manner. Controls were delivered at 125d, 140d, and 185d and the aortas acquired immediately after birth. None of the non-catheterized control animals (125 d, n = 4; 140 d, n = 5; 185 d, n = 5) had aortic vessel thrombi or vascular wall abnormalities. All 6 animals with short-term (6/6, 100%) and 18 animals with long-term (18/30, 60%) UAC placement displayed aortic thrombi and neointimal proliferation of the vascular wall. The majority (60%) of analyzed animals with UAC placement displaying neointimal hyperplasia were immunopositive for α-actin, indicating the presence of smooth muscle in these lesions. Conclusion Our findings suggest that both short- and long-term UAC use is associated with aortic wall pathological abnormalities compared to control animals. This study emphasizes the judicious use and early removal of UACs if possible in order to potentially prevent significant hemostatic and aortic wall vascular complications.
