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

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.

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
