“…An iatrogenic aneurysm arises secondary to an intravascular intervention that injures the vessel wall with a focal tear, occasionally complicated by dissection (167). Incomplete healing of the defect may progress to aneurysm formation, sometimes within just a few days after the initial injury (168).…”

Advances in medical diagnosis reveal that coronary artery aneurysms (CAAs) may develop in several clinical scenarios and manifest variable symptoms, imaging appearances, and outcomes. Aneurysms are pathologically classified into three groups: atherosclerotic, inflammatory, and noninflammatory. The last category is associated with congenital, inherited, and connective tissue disorders. Overlap exists among the groups, because secondary atherosclerotic change may be present in an aneurysm of any cause. Atherosclerosis is the most common cause of CAAs in adults, and inflammation is considered the underlying mechanism. In children, Kawasaki disease is the most likely cause of CAAs. In both conditions, the aneurysms are usually multiple and affect more than one coronary artery. Mycotic (infectious), iatrogenic, and cocaine-induced CAAs are also well documented. Most CAAs are discovered incidentally, but potential cardiovascular complications include thrombosis, occlusion, fistula formation, rupture, myocardial infarction, and cardiac tamponade. Imaging modalities to evaluate a suspected CAA include transthoracic echocardiography, angiographic cardiac catheterization, electrocardiographically gated computed tomographic angiography, cardiac magnetic resonance (MR) imaging, and MR angiography. Management is usually individualized, and options include surveillance, anticoagulant therapy, percutaneous stent or coil placement, surgical resection, and coronary artery bypass grafting.

Successful management of late coronary aneurysm after bare metal stent implantation: An insidious threat

Development of coronary arterial aneurysm (CAA) is a rare complication after stent implantation, and even more uncommon after bare metal stents (BMS) compared with drug eluting stents. The case is here presented of a 55year-old male with in-stent CAA, which developed 9 months after BMS implantation. The patient was treated with percutaneous re-implantation of BMS and at the clinical follow-up examination, 10 months after this treatment, there were no problems on the coronary angiography and the patient had no complaints. The treatment strategy is not clear for CAAs, so it must be decided after consultation between the cardiologist and cardiac surgeon. BMS re-implantation can be a successful treatment.

“…11 When thrombosed, a giant coronary artery aneurysm can mimic a mediastinal neoplasm on CT. Concentric regions of internal calcification are an indication of multiple episodes of repeated thrombosis and progressive enlargement. 12 Because these lesions may not appear obviously vascular on CT, one should consider the possibility of a thrombosed giant coronary artery aneurysm for an epicardial mass with internal calcifications along the right cardiac border. Surgical excision with coronary bypass grafting is the preferred treatment.…”

Computed Tomography Appearance of Unusual Nonaortic Thoracic Aneurysms and Pseudoaneurysms

Although aneurysms of the thoracic aorta are easily recognized on computed tomography (CT), nonaortic intrathoracic aneurysms and pseudoaneurysms are unusual and not often encountered by radiologists. These lesions can result in complications such as hemorrhage or symptoms from mass effect. In some cases, patients may be asymptomatic and the aneurysms may represent incidental findings. Radiologists should be familiar with the CT appearances of these rare vascular abnormalities to enable prompt diagnosis. The goals of this pictorial essay are to: (1) illustrate and describe the CT appearances of various unusual intrathoracic nonaortic aneurysms and pseudoaneurysms; (2) discuss the etiology and clinical significance of these lesions; and (3) discuss management options where appropriate.
