Inoperable pulmonary vascular disease in infants with congenital heart disease Shigeo Yamaki, MD, Ai Abe, MD, Koichi Tabayashi, MD, Masato Endo, MD, Hitoshi Mohri, MD, Tohru Takahashi, MD The Annals of Thoracic Surgery Volume 66, Issue 5, Pages 1565-1570 (November 1998) DOI: 10.1016/S0003-4975(98)00779-6
Fig 1 Semiserial sections of a small pulmonary artery from proximal (a) to distal (f) in a patient with absolute operative contraindication (Case 2). Note the complete obstruction (c) and medial atrophy in the periphery (e, f). (a–f, × 100 before 66% reduction.) The Annals of Thoracic Surgery 1998 66, 1565-1570DOI: (10.1016/S0003-4975(98)00779-6)
Fig 2 Small pulmonary arteries from the 8 patients with extremely thickened media of small pulmonary arteries. Note the markedly thickened media equal to or thicker than lumen. The Annals of Thoracic Surgery 1998 66, 1565-1570DOI: (10.1016/S0003-4975(98)00779-6)
Fig 3 Index of pulmonary vascular disease (IPVD) in patients with absolute operative contraindication, plexogenic arteriopathy, and extremely thickened media of small pulmonary arteries (extremely thickened arteries). Significant differences in the IPVD scores were found among the groups. The Annals of Thoracic Surgery 1998 66, 1565-1570DOI: (10.1016/S0003-4975(98)00779-6)
Fig 4 The mean medial thickness at a radius of 100 μm in the three groups. Significant differences were found among the three groups. The Annals of Thoracic Surgery 1998 66, 1565-1570DOI: (10.1016/S0003-4975(98)00779-6)
