Fig. prompting 3 Multiple segmental arterial ostial stenosis of the left and right pulmonary arteries, loss of blood flow in the posterior segment of the right upper lobe, and slight delay in pulmonary venous return.

Fig 4. Intravascular ultrasound images before and after balloon dilatation. IVUS Images showed honeycomb-like changes in the blood vessels, indicating muscular thrombosis. The most severe stenosis was 2.6mm². The lumen area of IVUS after dilatation was 4.78mm², and the PFG blood flow was grade 2. A PTCA balloon (2.0 mm × 20 mm Pioneer, 3.5 mm × 10 mm cutting balloon) was used for expansion using a micro-guide wire. We conducted a telephone follow-up three months post-discharge. The patient declined an examination admission. Family reported improved tolerance to flat walking/light activity; occasional morning chest tightness (relieved by nitroglycerin), possibly from residual PH.
