Abstract

Isolated unilateral absence of the pulmonary artery (UAPA) is a rare malformation. It is associated with respiratory symptoms, such as dyspnea or hemoptysis. We suggest that surgical treatment should be positively considered in patients with UAPA who are severely symptomatic and who have no other cardiovascular or respiratory comorbidities.

Highlights

A 41‐year‐old Japanese man was referred to us because of hemoptysis
Chest roentgenogram showed a mediastinal shift with no consolidations (Figure 1)
Chest‐enhanced computed tomography showed the absence of the left pulmonary artery from its origin, but the presence of a multitude of small vessels at the hilum from the bronchial, left internal thoracic, and left inferior phrenic arteries (Figure 2)

Summary

Introduction

A 41‐year‐old Japanese man was referred to us because of hemoptysis. Chest roentgenogram showed a mediastinal shift with no consolidations (Figure 1). Chest‐enhanced computed tomography showed the absence of the left pulmonary artery from its origin, but the presence of a multitude of small vessels at the hilum from the bronchial, left internal thoracic, and left inferior phrenic arteries (Figure 2).
