Case report: the 'vanished' left pulmonary artery.

ABSTRACT:

Background

We report a case of isolated ductal origin of pulmonary artery (DOPA) diagnosed in an asymptomatic newborn. The primary aim of this case is to highlight the need to investigate for DOPA in patients diagnosed with an 'absent branch pulmonary artery'.

Case summary

Our patient was an asymptomatic newborn infant, with normal intracardiac anatomy. He was initially diagnosed post-natally with 'absent left pulmonary artery' (LPA), though the LPA was seen in antenatal scans. He underwent angiography and was re-diagnosed with bilateral arterial ducts, with ductal origin of the LPA from the left arterial duct. The LPA was salvaged by first stenting the left arterial duct on Day 11 of life, with subsequent surgery to connect the LPA to the main pulmonary artery at 4.5 months old. The patient had an uneventful recovery after the surgery.

Discussion

Ductal origin of pulmonary artery is a rare vascular anomaly characterized by continuity of the left or right pulmonary artery (PA) with the distal end of the arterial duct, and discontinuity with the main PA. It is commonly misdiagnosed as pulmonary artery agenesis when the patent arterial duct constricts, with cessation of blood flow into the affected pulmonary artery. A high index of suspicion is necessary for diagnosis of DOPA. Once diagnosed, this lesion is clearly amenable to intervention, with benefits from unifocalization, to prevent late onset pulmonary hypertension or cardiac failure.

Project description:BackgroundPrimary pulmonary artery sarcoma (PAS) is a rare tumor that presents like pulmonary embolism (PE), primary chondrosarcoma in the pulmonary artery is even rarer and few studies have been reported. PAS are commonly misinterpreted as in a clinical setting, many patients initially receive anticoagulant and thrombolysis therapy, but failed to respond. Management of this condition is difficult and prognosis is poor. We report a case of primary pulmonary artery chondrosarcoma that was initially misdiagnosed as PE and Inappropriate interventional therapy was performed, but with poor response. Finally, patient received surgical treatment, postoperative pathology confirmed primary pulmonary artery chondrosarcoma.Case descriptionA 67-year-old woman who had presented with cough, chest pain and shortness of breath for more than 3 months. Computed tomography pulmonary angiography (CTPA) showed filling defects were seen in the right and left pulmonary arteries, spreading to the outer lumen. The patient was initially diagnosed with PE and underwent transcatheter aspiration for pulmonary artery thrombus, transcatheter thrombolysis, and inferior vena cava filter placement at a local hospital, but with poor response. She was then referred for pulmonary artery tumor resection, endarterectomy and pulmonary arterioplasty. Histopathological examinations confirmed a diagnosis of primary PAS (chondrosarcoma). The patient developed in situ recurrence of pulmonary artery tumors in 10 months after surgery and received six cycles of adjuvant chemotherapy. The lesions progressed slowly after chemotherapy. The patient subsequently developed lung metastasis in 22 months and died of heart failure and respiratory failure 2 years after surgery.ConclusionsPAS is an extremely rare and the clinical symptoms and radiological features often mimics PE, therefore When doctors make differential diagnosis of pulmonary artery mass lesions, especially when the anticoagulation and thrombolytic effects are very poor. They need to be alert to the possibility of PAS so that early diagnosis and early treatment can prolong the survival of patients.
