Emergency surgery is the only effective treatment of ruptured abdominal aortic aneurysms, even though morbidity and mortality rates remain high. We have studied the feasibility of left retroperitoneal aortic exposure in these cases in an effort to reduce postoperative complications. Over a 33 month period, 29 patients underwent emergency surgery for either a ruptured or symptomatic infrarenal abdominal aortic aneurysm. Of 13 patients with ruptured aneurysms, 4 underwent repair through a midline transperitoneal approach (3 deaths) whereas the remaining 9 were repaired through the retroperitoneal exposure (1 death). Supraceliac aortic clamping through the same incision prior to aneurysm exposure maintained hemodynamic integrity. The remaining 16 patients with symptomatic aneurysms were all treated through the retroperitoneal exposure (3 deaths). In the retroperitoneal groups, the cause of death was cardiac in two patients, hypertensive stroke in one, and necrotizing pancreatitis in one. Morbidity consisted of prolonged intubation, respiratory distress syndrome, and thrombophlebitis in one patient each and acute tubular necrosis in two patients. We believe that the left retroperitoneal approach is a useful option in the emergent treatment of abdominal aortic aneurysms.

Chylous ascites is an unusual postoperative complication that can lead to significant mechanical, nutritional, and immunologic consequences. We present the report of a patient with chylous ascites after abdominal aortic aneurysm repair. Paracentesis is essential for diagnosis and is often useful in the initial management of the patient with mechanical respiratory distress. Nonoperative management is appropriate, but careful attention must be given to the patient's nutritional status. Elemental diet supplementation or total parenteral nutrition may be necessary to minimize lymph flow. The sequestration of lymphocytes into the ascitic fluid may result in a profound decrease in absolute lymphocyte count. With appropriate nutritional support the prognosis of postoperative chylous ascites is excellent and reoperation rarely necessary.

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.

Coagulopathy during massive haemorrhage increases morbidity and mortality rates. The modalities of treatment by transfusion of fresh frozen plasma (FFP) are a matter of debate. According to most clinical practice guidelines, FFP administration is driven by coagulation tests but, in cases of massive transfusion, patient management may be delayed whilst awaiting results and thawing FFP. Several retrospective cohort studies of military or civilian multiple trauma casualties requiring massive transfusion (>10 red blood cells (RBC) within 24h) have suggested that early use of FFP and high FFP:RBC ratios (approaching 1) might improve survival and lessen morbidity. However, the methodology of these studies is suboptimal. They are subject, in particular, to survival bias. Massive FFP transfusions can also lead to an enhanced incidence of transfusion-related acute lung injury (TRALI), acute respiratory distress syndrome (ARDS), and multi-organ failure. At the present time, it is clear that FFP transfusion should be initiated early with a high FFP:RBC ratio in massive bleeding associated with haemostatic abnormalities such as multiple trauma. This does not imply that such a recommendation can be extended to the correction of high blood loss in other situations such as scheduled surgery. Actually, very few patients are likely to derive benefit from a 1/1 FFP:RBC transfusion strategy. They are chiefly multiple trauma victims with haemorrhagic shock and cases of ruptured abdominal aortic aneurysm. In other patients, in order to minimize risks and costs, a more parsimonious FFP use policy remains the best option until evidence for the benefit of 1/1 FFP:RBC is demonstrated.
