Chest pain while gardening: a Stanford type A dissection involving the aortic root extending into the iliac arteries—an uncommon and potentially catastrophic disease process

Extensive aortic dissection (Stanford Type A) presenting with confusion in a patient: a case report

Spontaneous extensive aortic dissection is rarely documented in the literature with a misdiagnosis rate of up to 38% in previous studies. Vital signs and clinical manifestations vary and depend on the extent of the dissection and location. We present a rare case of extensive Stanford Type A dissection in a 60-year-old female patient who presented with confusion. Type A aortic dissection is a surgical emergency that is important for clinicians to have a low threshold of suspicion of the life-threatening condition due to the diverse and potentially atypical clinical presentation of aortic dissection.

Early and late outcomes of non-total aortic arch replacement for repair of acute Stanford Type A aortic dissection

OBJECTIVE

This study evaluated the early and late outcomes of non-total aortic arch replacement for acute Stanford A aortic dissection.

METHODS

131 cases of acute Stanford Type A aortic dissection with no rupture admitted to our hospital from January 2016 to December 2019 were selected for non-total aortic arch replacement. According to different surgical methods, 51 patients with tear-oriented ascending/hemiarch replacement were included in Group A, and 80 patients who underwent total arch replacement surgery were enrolled in Group B. The perioperative indicators, 30-day mortality rate, and the incidence of postoperative complications were compared between the two groups, and the survival rate of patients were compared by follow-up after discharge.

RESULTS

The cardiopulmonary bypass time, cardiac perfusion time, invasive ventilation and ICU hospitalization in Group A were critically shorter than those in Group B (P<0.05). The incidence of transient cerebral dysfunction in Group A was substantially lower than that in Group B (P<0.05). The difference of comparison in perioperative mortality, incidence of permanent neurological dysfunction, and incidence of acute kidney and liver damage between the two groups was statistically insignificant (P>0.05). In addition, the two groups had statistically insignificant difference in survival during postoperative follow-up (P>0.05).

CONCLUSION

For acute Stanford type A aortic dissection without rupture in aortic arch, the non-total aortic arch replacement has simple surgical method with high perioperative safety and long-term efficacy that similar to total arch replacement.
