Aorta Related and All-cause Mortality in Patients with Aortic Intramural Haematoma.

OBJECTIVES: The prognosis of patients with intramural haematoma (IMH) of the aorta beyond the first year after diagnosis remains largely unknown. In particular, patients that do not undergo interventions are lost to follow-up. The aim was to assess medium-term outcome in IMH patients. METHODS: Post hoc analysis of 63 consecutive patients presenting with IMH between 1999 and 2013 was performed. Patients meeting imaging criteria at the first presentation were included even if follow-up imaging showed evidence of intimal disruption or false lumen flow. RESULTS: Eighteen patients presented with type A and 45 with type B IMH (29% vs. 71%, p < .001). The mean age was 71 ± 9.2 years, range 42-88 years. Follow-up was completed in 97% of patients by May 2017 and represents a mean follow-up of 6.3 ± 3.6 years. Freedom from intervention in patients with type B IMH was 40%. TEVAR was performed in 47% because of development, unmasking of an entry tear (57%), progression to acute type B dissection (24%), or subsequent dilation of the affected aortic segments (19%). Open repair was performed in 13% of type B IMH patients because of dilation of the descending aorta. In type A IMH, 89% underwent open repair. Aorta related 30 day, 6 month, 1 year, and late mortality were 1.6%, 6.3%, 6.3%, and 9.5%, respectively, for all IMH patients. All-cause 30 day, 6 month, 1 year, and late mortality were 1.6%, 6.3%, 6.3%, and 47.6%, respectively, for all IMH patients. Late mortality in type B IMH did not differ whether patients underwent TEVAR, open repair, or received best medical treatment only (26% vs. 22%, p = 1.0). CONCLUSIONS: Late aorta related mortality in IMH was low whereas all-cause mortality was substantial. Aorta related mortality in IMH patients only occurs during the first year after diagnosis. Interventions after the first year are rarely necessary.

Management of aortic aneurysms in patients with connective tissue disease.

Acute dissection and rupture of aortic aneurysms comprise for 1-2% of all deaths in developed countries. Dilation of the aorta is caused by several different mechanisms including inherited disorders of connective tissue. Recent reports estimate that 20% of patients presenting with thoracic aortic disease do have an underlying genetic basis of disease.

Bridge to operation with the GPIIb/IIIa inhibitor abciximab in high-risk coronary patients.

BACKGROUND: Glycoprotein-IIb/IIIa inhibitors are now frequently used in the cardiological treatment of high-risk coronary patients even if the patient is considered suitable for surgical intervention. However, there is no consensus whether GPIIb/IIIa inhibitors should be stopped before operation because of an increased risk of bleeding or if surgery should even be delayed until the anticoagulating effect subsides. METHODS: From June 2002 to August 2003 140 patients who had to undergo primary aorto-coronary bypass for ongoing myocardial ischemia were enrolled in the present study. The patients received either clopidogrel, aspirin and heparin or additionally abciximab until operation. RESULTS: Although the intraoperative need for blood products was higher in the abciximab group, there was no significant difference in postoperative blood loss. The hemodynamic situation of the abciximab patients after the operation was better compared to the other groups. 30-day mortality was not increased when compared to the elective control group (6.7 % vs. 6.1 %). CONCLUSION: The GPIIb/IIIa inhibitor abciximab can be safely used as a bridge to operation and results in a better hemodynamic outcome in high-risk coronary patients while reducing the incidence of major ischemic events.
