Fibromuscular dysplasia of the brachial artery in patients with spontaneous coronary artery dissection: a case series and literature review

Spontaneous coronary artery dissection (SCAD) is diagnosed in a very small percentage of patients with suspected acute coronary syndromes who undergo emergency coronary angiography. Although fibromuscular dysplasia (FMD) is known to coexist in patients with SCAD, the vascular sites of FMD and their...

Description
Summary:Spontaneous coronary artery dissection (SCAD) is diagnosed in a very small percentage of patients with suspected acute coronary syndromes who undergo emergency coronary angiography. Although fibromuscular dysplasia (FMD) is known to coexist in patients with SCAD, the vascular sites of FMD and their frequency have not yet been clarified. We retrospectively reviewed the medical records of 16 patients who were diagnosed with and treated for SCAD at our hospital between 1 January 2011 and 31 January 2023. We have summarized their baseline and clinical characteristics and medical variables, including coronary and upper extremity angiography and in-hospital outcomes. One of our patients had concurrent cardiac tamponade requiring pericardial drainage, and another went into hemorrhage shock the following day from dissection of the gastric retroperitoneal artery. Characteristic angiographic features of partial or diffuse nonatherosclerotic stenosis were observed mainly in the distal parts of the coronary arteries or their branches. Notably, in six patients with SCAD who underwent upper extremity angiography, FMD of the brachial artery was revealed. For the first time, to our knowledge, we found a high prevalence of multifocal FMD of the brachial artery in patients with SCAD.
