Case report: Woven-like coronary arteries in a patient with polycythemia vera

Abstract

Background

Woven coronary artery (WCA) is a rare and underdiagnosed congenital anomaly that involves multiple thin and tortuous epicardial arterial conduits reassembling distally into a single lumen. Recanalized thrombus may present as woven-like coronary arteries, appearing similar to WCA on angiographic images.

Case presentation

A 58-year-old female patient with intermittent chest pain for 5 years and polycythaemia vera (PV) for 8 years. The left anterior descending artery was presented like WCA on coronary angiography and finally confirmed as recanalized thrombus by optical coherence tomography(OCT), which might have been caused by PV. Given the patient’s high thrombotic risk of PV and thrombotic changes in the left circumflex artery (LCX), we ultimately chose a conservative treatment without stenting.

Conclusions

OCT would be needed for the diagnosis and differential diagnosis of woven-like coronary arteries. And physicians should take an appropriate treatment in a personalized way in patients with PV.
