Endovascular management of hemoptysis in a known case of tetralogy of fallot and tuberculosis complicated with aspergilloma: a case report
Egyptian Journal of Radiology and Nuclear Medicine volume 53, Article number: 140 (2022)
Hemoptysis is a life-threatening complication due to bleeding either from hypertrophied bronchial arteries or enlarged non-bronchial systemic collaterals, having multiple etiologies. Bronchial artery embolization (BAE) is a minimally invasive modality of management that can effectively manage moderate-to-severe hemoptysis.
We report the case of a 25-year-old female with moderate-to-severe hemoptysis. There was prior history of tuberculosis and treatment with anti-tubercular therapy 6 months back. There was also a background of tetralogy of Fallot(TOF) with symptoms of chronic breathlessness and palpitations. Imaging evaluation with X-ray and HRCT thorax revealed a cavity in the left upper lobe with dependent soft tissue, implying a diagnosis of aspergilloma in an old tubercular cavity. TOF and right-sided aortic arch were noted. CT bronchial angiography showed dilated and tortuous left bronchial artery, as well as non-bronchial systemic collaterals from the ipsilateral internal mammary artery. Endovascular management was achieved by super-selective catheterization and embolization of the involved branch of the left bronchial artery and selective embolization of non-bronchial systemic collaterals from the ipsilateral internal mammary artery.
BAE has a high clinical success rate and is recommended as first-line therapy in the management of massive hemoptysis. The CT pulmonary angiography, as well as the pre-embolization angiogram, is very important to detect the source of hemoptysis from the non-bronchial systemic circulation, increasing the success rate and decreasing the incidence of recurrence. BAE is effective even in presence of underlying vascular anomalies such as Fallot of Tetralogy.
Hemoptysis due to bleeding from enlarged and hypertrophied bronchial arteries and non-bronchial systemic collaterals is common and could be life threatening . Most common etiologies are tuberculosis, pulmonary neoplasms, cystic fibrosis, bronchiectasis, chronic pulmonary aspergillosis  and congenital conditions like Tetralogy of Fallot (TOF) and pulmonary agenesis . Along with the medical management of the underlying disease, bronchial artery embolization (BAE) is safe and effective therapy for moderate-to-severe hemoptysis .
We report a case of a 25-year-old female who came to our hospital with complaints of mild fever and recurrent moderate-to-severe hemoptysis (around 3 episodes over a week, approximately 350–500 ml blood loss). She was treated for active pulmonary tuberculosis and completed anti-tubercular treatment 6 months back. She was a known case of TOF and had related symptoms of chronic breathlessness and palpitations.
On physical examination, she was a malnourished, anemic (Hemoglobin- 11 g/dL) and had digital clubbing. BP at the time of admission was of 120/74 mm of Hg, a pulse of 110 beats per minute, and oxygen saturation of 90%. On respiratory examination, there were left upper lobe crepitations with reduced air entry in the left upper zone. A systolic murmur was also appreciated on cardiac auscultation. Rest of the systemic examination was unremarkable. Coagulation profile (Platelets—1.2 lacs, prothrombin time-13 s, international normalized ratio-1.2) was normal.
Chest radiography showed left upper lobe cavity with dependent soft tissue and associated pleural thickening indicating aspergilloma in old tubercular cavity. High-resolution computed tomography (HRCT) and CT angiogram were done which confirmed the findings of aspergilloma in tuberculous cavity with dilated and tortuous left bronchial artery(3.2 mm), arising as a branch of the left intercosto-bronchial trunk (Fig. 1). Also, some tortuous vessels were seen reaching the pleural thickening from the ipsilateral internal mammary artery. There was no evidence of Rasmussen aneurysm. Tetralogy of Fallot and right-sided aortic arch configuration was noted. In view of significant hemoptysis and dilated and tortuous bronchial arteries, endovascular embolization of bronchial arteries and non-bronchial systemic collaterals was planned. Using Sim 1 Catheter and Terumo J-shaped guidewire, selective angiography of left bronchial system was done. Findings revealed intercosto-bronchial trunk on the left side giving rise to the dilated and hypertrophied left bronchial artery (unusual anatomical variant). Super-selective catheterization of that branch was done using Progreat microcatheter (Terumo Interventional Systems, NJ, USA), and embolization was performed using 350u polyvinyl alcohol particles mixed with formed gelatin sponge slurry (Fig. 2). Similarly, selective cannulation of left subclavian artery was done using 5F picard catheter, followed by Progreat microcatheter (Terumo Interventional Systems, NJ, USA) to enter the left internal mammary artery, and embolization was performed using 350u polyvinyl alcohol particles mixed with formed gelatin sponge slurry embolization of non-bronchial systemic collaterals from the left internal mammary artery (Fig. 3). The patient’s postoperative course was uneventful. She was hemodynamically stable (blood pressure: 116/80 mmHg, heart rate around 72 bpm) and was discharged after 2 days with improving blood parameters (hematocrit 34%, hemoglobin 11.2 g/dL). She was then referred to cardiothoracic surgery for management of congenital heart disease.
Chronic pulmonary aspergillosis can result in moderate-to-significant hemoptysis which could be life threatening and needs emergent treatment . Patients with acyanotic congenital heart disease are more susceptible to common infections like pulmonary tuberculosis(TB) . However, few case reports are available in the literature describing the increased incidence of mycobacterium tuberculosis in cyanotic heart diseases like tetralogy of Fallot (TOF) . Our patient was a diagnosed case of TOF with right-sided aortic arch and left-sided intercosto-bronchial trunk which is a very rare anomaly . Aspergilloma is a form of chronic pulmonary aspergillosis that develops in a pre-existing lung cavity usually secondary to tuberculosis, sarcoidosis or bronchiectasis. The prevalence of aspergilloma in patients with pulmonary cavities secondary to pulmonary tuberculosis is 1.2 million worldwide  and is more common in Africa and south east Asia. Although the affected patients are mostly asymptomatic, however, moderate-to-massive hemoptysis has been reported predominantly due to hypertrophied bronchial artery and rarely secondary to pulmonary artery pseudo-aneurysm . BAE is considered as first-line therapy in emergency management of massive hemoptysis with high clinical success and low complication rates . The findings that make our study unique are the combination of cyanotic heart disease(TOF), right-sided aortic arch, left intercosto-bronchial trunk causing challenges in BAE in a patient with pulmonary tuberculosis complicated by aspergilloma. BAE can be complicated by non-target embolization resulting in major side effects like spinal cord ischemia, transient dysphagia, aortic dissection or cortical blindness, however, no such complication was encountered in our case . On 3 months follow-up, our patient did not have any episode of hemoptysis and is planned for surgery for congenital heart disease.
TOF with right-sided aortic arch and left intercosto-bronchial trunk is a rare congenital anomaly. BAE has high clinical success rates and is recommended as a first-line therapy in the management of massive hemoptysis along with embolization of non-bronchial systemic circulation as diagnosed on pre-embolization angiograms.
