Clinical features of pregnancy-associated aortic dissection and pregnancy outcomes.
Article in BMC pregnancy and childbirth, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPregnancy complicated by aortic dissection is a rare and severe condition. Due to limited clinical experience, there are currently no standardized management guidelines. Therefore, we summarized and analyzed the clinical data of 33 patients with aortic dissection during pregnancy to gain relevant experience.
methodA total of 33 pregnant women with aortic dissection admitted to the First Affiliated Hospital of Zhengzhou University and the First Affiliated Hospital of Dali University during 13 years from February 1, 2012 to February 28, 2025 were included. The average age was 32.27 years (range: 23–43 years), and the average gestational age at the occurrence of aortic dissection was 31 ± 7 weeks. There were 17 cases (51.5%) of type A aortic dissection (TAAD) and 16 cases (48.5%) of type B aortic dissection (TBAD). Thirteen cases of TAAD (76.5%, 13/17) and ten cases of TBAD (62.5%, 10/16) occurred during late pregnancy or postpartum. Management strategies were based on anatomical type and gestational age (i.e., prioritizing surgery, medical management, or surgery followed by delivery).
resultsAmong the 33 patients, 29 (87.9%) underwent aortic repair surgery, including 14 cases of TAAD (82.4%, 14/17) and 15 cases of TBAD (93.8%, 15/16). A total of 28 patients underwent cesarean section. Among them, 13 cases of TAAD (76.5%, 13/17), 15 cases of TBAD (93.8%). Out of the 33 patients, 6 deaths occurred (18.2%), including 4 TAAD cases with a mortality rate of 23.5% and 2 TBAD cases with a mortality rate of 12.5%. The neonatal mortality rate was 6%, all occurring in TAAD cases.
conclusionFor pregnant women presenting with thoracolumbar pain and a high suspicion of aortic dissection, timely computed tomography angiography (CTA) examination should be performed to avoid missed or delayed diagnosis. Management of aortic dissection during pregnancy should be based on the anatomical type and gestational age to determine the timing of surgery and delivery, which significantly influences maternal and fetal survival rates.
