Estudio prospectivo aleatorizado sobre el impacto de las medidas fast track en la cirugía abierta de aneurismas de aorta abdominal / Randomised, prospective study on the impact of fast track measures in the open surgery of abdominal aortic aneurysms

INTRODUCCIÓN: La implantación de las medidas fast track (FT) en la reparación abierta (RA) de aneurismas de aorta abdominal (AAA) no está convenientemente evaluada en nuestro medio. OBJETIVO: Queremos valorar el impacto de la instauración de medidas FT en nuestros pacientes. MATERIAL Y MÉTODOS: Estudio prospectivo aleatorizado (grupo control, grupo FT) de pacientes consecutivos intervenidos de manera electiva de AAA >55 mm infrarrenal por vía retroperitoneal mediante injerto recto. En el grupo FT se instauran medidas de optimización perioperatorias: ausencia de preparación intestinal, reducción del ayuno preoperatorio, administración de bebida carbohidratada 2 h antes de la intervención, control del dolor con elastómero preperitoneal, movilización y dieta precoces. Hemos comparado las variables postoperatorias: síndrome de respuesta inflamatoria sistémica (SIRS) postoperatorio, necesidad de transfusión, estancia en reanimación, días de ingreso y reintervenciones. RESULTADOS: De julio de 2011 a enero de 2014 se ha incluido a 38 pacientes (edad 68 años DE = 6,28; 97,4% hombres), 24 pacientes en grupo control y 14 en el grupo FT. La media de días de ingreso (6,17 vs. 4,64 en grupo FT) y de transfusiones son menores en el grupo FT (p < 0,05). La estancia en reanimación y las reintervenciones son menores en el grupo FT, aunque sin significación estadística. La incidencia de SIRS tras 48 h desde la intervención en el grupo FT fue 21,4% y del 54,16% en el grupo control (RR = 0,38; IC 95%: 0,15-0,61). CONCLUSIONES: Las medidas de optimización tipo FT podrían disminuir la incidencia de SIRS y reducir la estancia hospitalaria de los pacientes intervenidos de AAA

INTRODUCTION: Implementation of fast track (FT) measures for abdominal aortic aneurysm (AAA) open repair (OR) has not been sufficiently evaluated in our area. OBJECTIVE: The impact of implementing FT measures in our patients. MATERIAL AND METHODS: A prospective, randomised study (control and FT groups) was designed and conducted on patients with an infrarenal AAA >55 mm between July 2011 and January 2014 undergoing elective OR by retroperitoneal approach using straight graft interposition were included. The following perioperative optimisation measures were established in the FT group: No bowel preparation, reduced pre-operative fasting, administration of carbohydrate drink up to 2 h before surgery, pain control with pre-peritoneal elastomer, early onset of mobilisation and diet. A comparison was made of the postoperative variables: Postoperative systematic immune response syndrome (SIRS), need for transfusion, stay in resuscitation, hospital stay, and further interventions. RESULTS: A total of 38 patients were included, with a mean age of 68 years (SD = 6.28), of which 97.4% were men. There were 24 patients in control group and 14 in FT group. No statistically significant differences (NSSD) were found in comorbidities of both groups. Mean hospital stay was 6.17 vs. 4.64 days in the FT group, and transfusions were lower in the FT group, with statistically significant differences. Stay in resuscitation unit and re-interventions were also lower in FT group, although NSSD. The incidence of SIRS 48 h after surgery in FT group was 21.4% compared to 54.16% in control group (RR = 0.38, 95% CI; 0.15 - 0.61). CONCLUSIONS: The FT optimisation measures may reduce the incidence of SIRS, and reduce hospital stay in patients undergoing open repair of AAA

Diagnosis and treatment of congenital abdominal aortic aneurysm: a systematic review of reported cases.

BACKGROUND: Congenital abdominal aortic aneurysm (AAA) is distinctly rare in infants and children and carries a high mortality rate. Our objective was to summarize the experience of the diagnosis and treatment in patients with congenital AAA. METHODS: Reported cases of congenital AAA published prior to November 8, 2014, were identified through PubMed, EMBASE, Web of Science, and reference lists. All selected cases were evaluated for main clinical characteristics. RESULTS: Twenty-six cases of congenital AAA were identified in the English language literature. Congenital AAA occurred primarily in children under three years old, but it was also found in young adults and fetuses. With regards to the localization, the great majority of congenital AAA was infrarenal AAA. The majority of the AAA patients lacked specific symptoms, and a painless pulsatile abdominal mass was the most common clinical presentation. The diagnosis of AAA was based on ultrasound scanning in twenty-five cases, multi-slice spiral computed tomography angiography (MSCTA) in sixteen cases, and magnetic resonance angiography (MRA) in nine cases. Histopathological analyses were available in seven cases. Seven patients received conservative management. Surgical treatment was performed in seventeen cases, and open repair with an artificial graft was the main surgical intervention. The mortality associated with congenital AAA was high (30.76%). Ruptured aneurysm and renal failure were the main causes of death. CONCLUSIONS: Good outcomes can be achieved in children with early identification of congenital AAA and individualized surgical repair with grafts.

Tratamento endovascular de aneurisma de aorta abdominal em paciente com rim em ferradura: relato de caso / Endovascular treatment of abdominal aortic aneurysm in patient with horseshoe kidney: a case report

O rim em ferradura é uma das anomalias urológicas congênitas mais comuns e está presente em cerca de 0,12% dos pacientes com aneurisma de aorta abdominal. O reparo cirúrgico convencional está associado a dificuldades técnicas que provavelmente aumentam a morbidade e a mortalidade, mas que podem ser evitadas com o tratamento endovascular. Relatamos um caso de um paciente de 64 anos com rim em ferradura e aneurisma de aorta abdominal, que foi submetido ao reparo endovascular do aneurisma com sucesso.

The horseshoe kidney is one of the most common urologic anomalies and is present in about 0,12% of the patients with abdominal aortic aneurysm. The conventional surgical repair is associated with technical difficulties that probably increase morbidity and mortality, but can be averted by the endovascular treatment. We report a case of a 64-year-old patient with horseshoe kidney and abdominal aortic aneurysm, who underwent endovascular repair with success.

An idiopathic congenital abdominal aortic aneurysm with impending rupture in a 23-month-old boy.

Abdominal aortic aneurysms are distinctly uncommon in infants and children. These aneurysms, which are idiopathic in nature without any definite predisposing factors, are exceedingly rare. We present the case of a giant idiopathic congenital infrarenal abdominal aortic aneurysm with impending rupture in a 23-month-old boy, which was successfully treated with surgical repair using a cryopreserved cadaveric allograft. To the best of our knowledge, this is the oldest case and the third successful treatment of an idiopathic congenital abdominal aortic aneurysm repaired with a cryopreserved allograft in infants and children. Continued follow-up with multimodality imaging is required.

Extensive congenital abdominal aortic aneurysm and renovascular disease in the neonate.

Primary congenital abdominal aortic aneurysm is an extremely rare entity, with only 15 patients reported in the literature. Options for repair are often limited secondary to branch vessel size and other anatomic limitations. We present a neonate diagnosed with an abdominal aortic aneurysm on prenatal ultrasound. A postpartum computed tomography angiogram revealed an extensive type IV thoracoabdominal aortic aneurysm extending to the aortic bifurcation and resulting in bilateral renal artery stenosis. The unique features of this patient and challenges in management are discussed.

Congenital abdominal aortic aneurysm with porencephaly: a case report.

An abdominal aortic aneurysm is a rare disease in the paediatric population and is mainly caused by intrauterine infection, connective tissue diseases, such as Ehlers-Danlos syndrome and Marfan's syndrome, and iatrogenic trauma due to umbilical artery catheterization. Although several cases have been reported in the English literature, they were rarely diagnosed prenatally. Vascular obstruction in utero is also believed to be the major cause of porencephaly. Recently, gene mutations have been reported as the cause of both the above-mentioned diseases. We present a prenatally diagnosed case of congenital abdominal aortic aneurysm with porencephaly.

Pulmonary sequestration supplied by giant aneurysmal aortic branch.

We report a case of an intralobar sequestration supplied by a 13-cm aneurysmal vessel originating from the abdominal aorta. The malformation was discovered during a roentgenogram investigation of an abdominal infrarenal aneurysm. During the endovascular repair of the abdominal aneurysm, the giant feeding vessel of the pulmonary sequestration was embolized. Two days later the patient underwent an uneventful resection of the malformation en bloc with the right lower lobe through a standard right thoracotomy.

Anatomical repair of a congenital aneurysm of the distal abdominal aorta in a newborn.

Congenital (primary) neonatal abdominal aortic aneurysm (AAA) is an extremely rare truncular arterial abnormality among numerous congenital vascular malformations. Only seven cases have been reported as congenital origin in newborns. This report presents the case of a male infant in whom a 33-mm congenital AAA was diagnosed prenatally and was successfully treated 10 days after birth without exogenous graft material or aneurysmorrhaphy. Follow-up study at 39 months demonstrated excellent clinical, ultrasound scan, and computed tomography scan findings. Anatomic reconstruction with native vessels is the preferred surgical technique to ensure the child's potential for harmonious growth.

Primary congenital abdominal aortic aneurysm: a case report with perinatal serial follow-up imaging.

Abdominal aortic aneurysms in neonates and infants are rare and are usually associated with infection, vasculitis, connective tissue disorder, or iatrogenic trauma such as umbilical catheterization. An idiopathic congenital abdominal aortic aneurysm is the least common category and there are few descriptions of the imaging features. We present the antenatal and postnatal imaging findings of an idiopathic congenital abdominal aortic aneurysm including the findings on US, MRI and CT.

Use of Palmaz stents in a newborn with congenital aneurysms and coarctation of the abdominal aorta.

Anomalies of the abdominal aorta are rare in the pediatric population limiting the reported knowledge base from which management decisions can be made. A 3-week-old male with congenital abdominal aortic coarctation and multiple aneurysms presented with malignant hypertension. We report the safe deployment of overlapping Palmaz stents using a 4-French catheter delivery system with significant relief of the coarctation gradient and restoration of adequate renal perfusion.

[Congenital abdominal infrarenal aortic aneurysm in infants: 2 case reports and literature review]. / Anevrysme congenital de l'aorte abdominale sous-renale chez le nourrisson: cas cliniques et revue de la littérature.

Abdominal aortic aneurysm is extremely rare in infant and is generally due to infection, umbilical artery catheterization, vasculitis, connective tissue diseases and tuberous sclerosis. At the absence of these evident causes, it is a congenital primary aortic aneurysm which is exceedingly rare and only a few cases have of which have been reported. Here we report two cases of aortic wall reconstruction done by a Gore tex patch. The immediate result is excellent with a reestablishment of the femoral pulse and an excellent Doppler control. The problem which we may face in the future is probably the aortic out come with this Gore tex patch a continaons follow up of these patients is necessary.

Congenital abdominal aortic aneurysm and renal dysplasia.

We report a 6-month-old boy with abdominal aortic aneurysm and dysplastic kidneys. To the best of our knowledge, this is the first report of abdominal aortic aneurysm associated with dysplastic kidneys. Serial US, MR angiography and scintigraphy were performed. No underlying cause of the aneurysm was identified. Spontaneous thrombosis occurred within 2.5 years of diagnosis, but there was persistent renovascular hypertension and progressive deterioration of renal function.

Congenital abdominal aortic aneurysm: a case report.

Abdominal aortic aneurysm (AAA) is distinctly uncommon in infants and children, and usually results from infection, iatrogenic trauma, vasculitis, connective tissue disorder, or tuberous sclerosis. Congenital "primary" neonatal AAA is exceedingly rare. The few reported cases of repair of congenital AAA describe use of synthetic graft material or aneurysmorrhaphy. We report the first successful treatment of a known 6 cm congenital infrarenal AAA repaired with a 5 mm cryopreserved allograft in a 4-month-old infant girl. The graft was pretreated with an antigen reduction process (SynerGraft), which preliminary studies suggest may inhibit allograft degeneration. The postoperative course was unremarkable. Lower extremity pulses and results of duplex ultrasound flow studies remained excellent at 14-month follow-up. Panel reactive antibodies against class I alloantigens remain negative. The use of an antigen-reduced allograft provides an acceptable conduit, which potentially may decrease allograft degeneration and relative graft stenosis associated with growth of the child, but requires follow-up.

Congenital abdominal aortic aneurysm causing renovascular hypertension, cardiomyopathy, and death in a 19-day-old neonate.

A full-term baby girl who was sent home day of life 2 was admitted to the hospital on day of life 7 for respiratory distress and poor feeding. The child was found to be hypertensive and in heart failure. Further workup led to the diagnosis of a suprarenal abdominal aortic aneurysm, but the infant had deteriorated clinically with heart failure, modest renal failure, renovascular hypertension, and no operative cure. The child died on day of life 20. Early diagnosis and prompt surgical resection are essential to managing this rare and lethal condition.

Congenital abdominal aortic aneurysm in the infant: case report and review of the literature.

Congenital abdominal aortic aneurysms are a distinct entity from acquired aortic aneurysms. The authors present the case of a 6-week-old boy with a 6-cm aneurysm involving the abdominal aorta and common iliac arteries. Three other cases of congenital aortic aneurysms are reviewed, and an approach to these rare patients is discussed. J Pediatr Surg 36:657-658.
