Purpose: To describe the successful endovascular repair and regression of an extensive descending thoracoabdominal aortic dissection associated with thoracic and abdominal aortic aneurysms. Case Report: An 83-year-old man presented with acute chest pain and shortness of breath. A descending thoracoabdominal aortic dissection that extended from near the left subclavian artery (LSA) to the right common iliac artery was found on computed tomography. Separate aneurysms in the thoracic and abdominal aorta were also identified. Staged endovascular procedures were undertaken to (1) close the single entry site and exclude the aneurysm in the thoracic aorta with an AneuRx thoracic stent-graft, (2) exclude the abdominal aneurysm and distal re-entry site with a bifurcated AneuRx endograft, and (3) treat a newly dilated thoracic segment between the LSA and first thoracic stent-graft. At 1 year, the false lumen had completely disappeared, the thoracic aneurysm had collapsed onto the endograft, and the abdominal aneurysm had shrunk by 30%. Conclusions: The potential to treat extensive aortic dissections with the hope that they might regress is promising, but repair of highly complex lesions involving one or more aneurysms in addition to the dissection requires meticulous imaging studies both preoperatively and intraprocedurally.

The Effects of Weekend Admission on the Outcomes and Management of Ruptured Aortic Aneurysms Objective: Ruptured aortic aneurysm is a condition with a high rate of mortality that requires prompt surgical intervention. It has been noted that in some conditions requiting such prompt intervention, in-hospital mortality is increased in patients admitted on the weekends as compared to patients admitted on weekdays. We sought to determine if this was indeed the case for both ruptured thoracic and abdominal aortic aneurysm and elucidate the possible reasons. Methods: Using the Nationwide Inpatient Sample (NIS), a publicly available database of inpatient care, we analyzed the incidence of mortality among patients admitted on the weekends compared to weekdays for ruptured aortic aneurysm. Ultimately the care of over 7,000 patients was analyzed for the primary endpoints. We adjusted for demographics, comorbid conditions, hospital characteristics, rates of surgical intervention, timing of surgical intervention and use of additional therapeutic measures. Results: Patients admitted on the weekend for both ruptured thoracic and abdominal aortic aneurysm had a statistically significant increase in mortality as compared to those admitted on the weekdays (OR 2.55 for Thoracic and 1.32 for Abdominal). By our analysis this is likely due to a delay in surgical care on the weekends. Conclusions: Weekend admission for ruptured aortic aneurysm is associated with an increased mortality when compared to those admitted on the weekend and this is likely due to several factors with the most predominant being a delay in surgical intervention.

We compared arterial growth to hemodynamic changes in the perinatal period in lambs. Blood pressure did not change significantly from 120 days gestation to 3 days postpartum, when it was 45.4 +/- 1.9 mmHg; however, pressure rose to 64.8 +/- 2.5 mmHg at 21 days postpartum. Thoracic and abdominal aortic and iliac and carotid arterial blood flows fell > 50% after birth but returned to fetal levels except in the abdominal aorta by 21 days postpartum. Blood flows in mesenteric (BFm) and renal (BFr) arteries increased between 120 days gestation (BFr = 13.4 +/- 1.4; BFm = 41.8 +/- 3.5 ml/min) and 140 days gestation (BFr = 25.9 +/- 1.8; BFm = 189 +/- 18 ml/min) and between 3 and 21 days postpartum (to BFr = 71.1 +/- 14.3; BFm = 334 +/- 59 ml/min). Elastin accumulation accelerated at 140 days gestation in all arteries except the thoracic aorta, in which elastin accumulation was always rapid. Collagen but not DNA accumulation also accelerated in most arteries. Postpartum dexamethasone (0.1 mg/kg twice a day) did not affect abdominal aortic elastin by 10 days of age (23.9 +/- 2.7 vs. 26.4 +/- 4.1 mg for controls); however, dexamethasone upregulated tropoelastin mRNA in fetuses. We hypothesize that cortisol stimulates elastin accumulation in late gestation. Postnatal elastin but neither collagen nor DNA correlated with blood flow changes at birth (r = 0.855, P < 0.05). We infer that accumulation of elastin is sensitive to blood flow rates during perinatal development.

AbstractA 65-year-old man, with previous open surgical repair of an infrarenal abdominal aortic, presented with acute complicated (paraplegia) Type B aortic dissection. He successfully underwent endovascular repair of the descending thoracic and abdominal aorta. Following the procedure, the neurological manifestations resolved. As he had a concomitant aneurysm of the right hypogastric artery (HGA), we executed a 10-minute balloon occlusion of this artery with evoked potential measurements to assess the risk of spinal cord ischemia after exclusion of the right HGA. The examination was interpreted as negative, and we proceeded with coil embolization of the right HGA and subsequent placement of an endograft landing distally within the external iliac artery. The postoperative course was totally uneventful, and the patient was discharged home 4 days after the operation. Computed tomography angiography follow-up at 1, 6, 12 and 24 months showed patency of all endografts without any signs of endoleak and effective remodeling of the descending thoracic aorta with volume reduction of the false lumen.
