Objective  We study whether using an intra-aortic balloon (IAB) during cesarean hysterectomy decreases delivery morbidity in patients with suspected morbidly adherent placentation. Study Design  This is a retrospective cohort study of deliveries complicated by suspected abnormal placentation between 2009 and 2016 comparing maternal and neonatal outcomes with an IAB placed prior to cesarean hysterectomy versus no IAB. The primary outcome included quantified blood loss (QBL). Results  Thirty-five cases were reviewed, 16 with IAB and 19 without IAB...

Arterial thrombosis of the newborn is rare and associated with poor prognosis, often attributed to umbilical arterial catheterization. The aortic and spontaneous forms are exceptional. Its severity requires fast and effective treatment. Although therapeutic means are numerous, no consensus has been established to date although thrombolysis and heparin therapy appear to give good results depending on the site and extent of thrombosis. We report a case of extensive thrombosis of the abdominal aorta in a 5-day-old newborn, revealed by acute hypernatremic dehydration...

Extensive perinatal myocardial infarction caused by coronary artery thrombosis is extremely rare and has a dismal prognosis. We report a 3.5-kg neonate who presented at birth with an extensive myocardial infarction caused by aortic root and left main coronary artery thrombus after an emergency cesarean section. We performed emergency surgical thrombectomy and insertion of extracorporeal membrane oxygenation support. After subsequent conversion to long-term left ventricular assist device with an EXCOR device (Berlin Heart, Berlin, Germany), the patient had no ventricular recovery after 163 days of support...

In neonates requiring balloon aortic valvuloplasty, both anterograde and retrograde approaches are feasible. A recent comparison of these two approaches is lacking. A retrospective cohort study of neonates at a single center undergoing BAV from 9/00 to 7/14 was performed. Records were reviewed including pre- and post-intervention echocardiograms and catheterization data. Comparisons of acute efficacy and procedural safety were made based on type of approach utilized. Forty-two neonates underwent BAV. Eleven cases utilized exclusively an anterograde approach, while 31 included a retrograde approach (including 4 with both approaches used)...

BACKGROUND: Thrombosis in neonates is commonly a central venous access device (CVAD) associated complication. Furthermore, a patent foramen ovale (PFO) is frequently seen in preterm infants. Even though a coincidence of both is not unusual, detaching of the thrombus and organisation of an aortic embolism has not been described until now. Treatment recommendations of CVAD-associated thrombosis in neonates do not consider frequently seen complications of preterm infants e.g. intraventricular haemorrhage...

The article reviews the intestinal ischemia theme on newborn and children. The intestinal ischemia may be either acute - intestinal infarction (by vascular obstruction or by reduced mesenteric blood flow besides the occlusive mechanism), either chronic. In neonates, acute intestinal ischemia may be caused by aortic thrombosis, volvulus or hypoplastic left heart syndrome. In children, acute intestinal ischemia may be caused by fibromuscular dysplasia, volvulus, abdominal compartment syndrome, Burkitt lymphoma, dermatomyositis (by vascular obstruction) or familial dysautonomia, Addison's disease, situs inversus abdominus (intraoperative), burns, chemotherapy administration (by nonocclusive mesenteric ischemia)...

Neonatal arterial thrombosis is unusual and generally associated with an arterial umbilical catheter. Spontaneous aortic thrombosis is exceptional but its severity is related to high mortality rate and renovascular morbidity. We report here the observation of a 10-day-old term infant showing a large abdominal aortic thrombosis revealed by cardiogenic shock induced by systemic arterial hypertension. The resolution was fast following anticoagulant and antihypertensive therapy. Etiologic investigations showed renal failure and moderate hyperhomocysteinemia controlled by a vitamin supplement...

Abdominal aortic thrombosis is a rare entity in neonates and has mostly been associated with umbilical artery or cardiac catheterization. We present a complicated case of an otherwise healthy neonate who developed thrombosis of abdominal aorta with renal failure. Therapy with intravenous heparin was unsuccessful, and thrombolysis was contraindicated because of disseminated intravascular coagulation so we decided to perform open thrombectomy using the left retroperitoneal approach. The following day, thrombosis recurred in the same extent and despite high risk of bleeding Alteplase was eventually given, which resulted in recanalization of the aorta 6 hours later...

Neonatal arterial thrombosis is a very rare entity with clinical findings resembling coarctation of aorta or interrupted aortic arch. A two day-old male newborn was admitted to a different hospital with difficulty in sucking and sleepiness. On echocardiographic examination, a diagnosis of interrupted aortic arch was made and he was treated with prostoglandin E2. When the patient presented to our center, physical examination revealed that his feet were bilaterally cold. The pulses were not palpable and there were ecchymotic regions in the lower extremities...

BACKGROUND AND AIM OF THE STUDY: Cardiac surgery during pregnancy is rarely required and potentially increases feto-maternal mortality. The study aim was to evaluate pregnancy outcomes in females who underwent open-heart surgery with cardiopulmonary bypass (CPB) during pregnancy. METHODS: Between 1999 and 2014, a total of 16 pregnant women (mean age 27 ± 7 years; mean gestational age 13 ± 7.7 weeks) underwent urgent cardiac surgery using CPB. The preoperative diagnosis included prosthetic valve dysfunction in 12 women (five aortic, seven mitral), native valve endocarditis and critical aortic stenosis each in one woman, and intracardiac masses in two women...

Congenital heart disease is the leading cause of infant death in the United States with over 36,000 newborns affected each year. Despite this growing problem there are few mechanical circulatory support devices designed specifically for pediatric and neonate patients. Previous research has been done investigating pediatric ventricular assist devices (PVADs) assuming blood to be a Newtonian fluid in computational fluid dynamics (CFD) simulations, ignoring its viscoelastic and shear-thinning properties. In contrast to adult VADs, PVADs may be more susceptible to hemolysis and thrombosis due to altered flow into the aorta, and therefore, a more accurate blood model should be used...

Hypoplastic left heart syndrome is the most common diagnosis among infants requiring cardiac extracorporeal life support (ECLS) in the neonatal period, with more than half of patients experiencing an ECLS-related complication. We present a case of nearly obstructing neoaortic thrombus during ECLS occurring in the early postoperative period after modified Norwood palliation of hypoplastic left heart syndrome. Stasis within the neoaortic root due to the increased ventricular afterload associated with venoarterial ECLS may have potentiated this complication...

The central aortic shunt, consisting of a Gore-Tex (polytetrafluoroethylene) tube (graft) connecting the ascending aorta to the pulmonary artery, is a palliative operation for neonates with cyanotic congenital heart disease. These tubes often have an extended length, and therefore must be angulated to complete the connection to the posterior pulmonary arteries. Thrombosis of the graft is not uncommon and can be life-threatening. We have shown that a viscous fluid (such as blood) traversing a curve or bend in a small-caliber vessel or conduit can give rise to marked increases in wall shear stress, which is the major mechanical factor responsible for vascular thrombosis...

The aortic thrombosis is not frequent during the neonatal period. The canalization of umbilical artery is the main risk factor. There are several options for the treatment, such as thrombolysis, thrombectomy and the anticoagulation, which are used in terms of the thrombosis localization and the symptoms that are observed. We present the case of a newborn who consulted for weak femoral pulses, coldness and poor perfusion of lower limbs. The aorta restriction was ruled out using the echocardiography; Doppler abdominal ecography showed aortic thrombosis at an underrenal level...

Left atrial thrombus in neonates is uncommon. We describe a newborn with coarctation of the aorta, in whom a thrombus confined to the left appendage was discovered on the first day of life and was thought to be a myxoma.

Although relatively rare, thromboembolic events are a major complication of invasive procedures, mainly vascular catheterization, required for the survival of neonates admitted to the neonatal intensive care unit. Sometimes symptoms may be ambiguous and the diagnosis may not be immediate. The clinical relevance of polymorphism of methilene tetrahydrofolate reductase (MTHFR) gene heterozigosity and of omocystein level in the genesis of these thromboembolic events are poorly understood. We report two cases of thrombosis of the abdominal aorta, mimicking aortic coarctation, in two neonates, successfully treated at diagnosis with 170 UI/Kg of low molecular weight heparin (LMWH) twice daily, without side effects...

Hypertensive crisis is a sudden rise in blood pressure above 99 c. for sex, age and height +5 mm Hg. Depending on patient's symptoms, hypertensive crisis can be divided into hypertensive emergency severe arterial hypertension with target organ insufficiency and/r damage (central nervous system, heart, kidney, eye), and hypertensive urgency - severe arterial hypertension without target organ insufficiency and damage with non-specific symptoms like: headaches, vertigo, nasal bleeding, nausea, and vomiting. The most common causes of hypertensive crisis in neonates and infants are renal artery thrombosis, broncho-pulmonary dysplasia, and coarctation of aorta; in older children - kidney diseases and renal artery stenosis...

Aortoiliac thrombosis is rare in infants and neonates. Protein C deficiency is frequently observed with venous thromboembolism, but off-late report of arterial thrombosis is increasingly common. We report a case of large infrarenal aortoiliac saddle and right popliteal artery thrombosis in a 7-month-old infant, with 3-mm atrial septal defect without clinical and Doppler evidence of deep vein thrombosis, presented with acute bilateral lower limb ischemic attack. Diagnosis was made by computed tomographic (C T) angiography of aorta and bilateral lower limbs...
