Catheter rehabilitation of occluded aberrant pulmonary artery

Rare Condition of Aberrant Arterial Supply to a Normal Lung: A Cases Series and Literature Review

Herein, we describe an aberrant artery to a normal lung, focusing on its classification, embryological hypotheses, diagnostic methods, and treatment modalities. We present three cases of aberrant arterial supply to a normal lung in various age groups (51 years, 5 months, and 29 years). The cases presented symptoms ranging from hemoptysis to respiratory distress. Successful transarterial embolization was performed in the 5-month-old infant. In addition, we collected case reports published from 1962 to the present from the literature to compare the trends in management and variations in manifestations.

Effectiveness of stenting and subsequent re-implantation of disconnected pulmonary artery to restore the pulmonary hemodynamics

INTRODUCTION

Early intervention in patients with congenitally disconnected pulmonary artery improves long-term outcome.

CASE PRESENTATION

We present 3 cases of isolated disconnected pulmonary artery in the absence of associated structural heart disease during a period of 3 years.

CONCLUSION

Transcatheter stenting of the feeding ductus arteriosus re-established pulmonary artery flow and growth. Successful surgical repair was achieved, and normal perfusion and complete function of the ipsilateral lung were regained.

Stenting and Reimplanting Disconnected Pulmonary Artery in Tetralogy of Fallot

Tetralogy of Fallot with absent pulmonary valve syndrome (TOF/APV) is a rare congenital malformation. Although pulmonary artery (PA) anomalies have been observed in TOF, its association with disconnected PA is extremely rare. We report successful stenting of the disconnected left PA in a 3-year-old boy with TOF/APV followed by surgical reimplantation. The significance of this transcatheter intervention for guidance during surgery and the importance of visualizing a ductal stump on angiography as an indicator of disconnected PA are discussed.
