[A case of coronary-pulmonary artery fistula with saccular aneurysm]
1Department of Internal Medicine, Kyushu Rousai Hospital.
Insights
A rare case of coronary-pulmonary artery fistula with saccular aneurysm was found in a 62-year-old female. Surgical resection successfully treated the condition, resolving the abnormal chest shadow and aneurysm.
Area of Science:
- Cardiology
- Vascular Surgery
Background:
- Coronary angiography (CAG) is increasingly used, leading to more frequent reports of coronary-pulmonary artery fistula.
- Coronary-pulmonary artery fistula with a saccular aneurysm is an exceptionally rare presentation.
Observation:
- A 62-year-old female presented with an abnormal chest shadow detected on imaging.
- CAG revealed a fistula between the left anterior descending coronary artery (LAD) and the pulmonary artery (PA), with a saccular aneurysm.
Findings:
- The fistula involved both proximal and distal segments of the LAD to the PA.
- A saccular aneurysm associated with the fistula posed a risk of rupture.
Implications:
- Surgical resection of the coronary-pulmonary artery fistula with saccular aneurysm was performed due to rupture risk.
- The patient showed favorable progress post-surgery, with resolution of the chest shadow and no evidence of the aneurysm on follow-up CAG.
Abstract:
Recently, due to the wide-spread use of coronary angiography (CAG), reports of coronary-pulmonary artery fistula have become more frequent. However, a case of coronary-pulmonary artery fistula with saccular aneurysm is very rare. We report a case of coronary-pulmonary artery fistula with saccular aneurysm which was discovered as an abnormal chest shadow. A sixty-two-year old female was admitted to our hospital with an abnormal chest shadow. CAG showed fistula from the left anterior descending coronary artery (LAD) proximal to the pulmonary artery (PA), and also from the LAD distal to the PA, with saccular aneurysm. Due to the risk of a rupture of the saccular aneurysm, we performed a resection. After this operation, no abnormal chest shadows appeared on the chest X-rays. CAG showed no saccular aneurysm and she is progressing favorably.
