Brown spots (arrows) depict PA wall hemorrhages and rough defects (4 mm-3 mm-2 mm in size); the asterisk corresponds to superficial dissection with intima detachment and media disorganization; d Macroscopic view of a RF-induced lesion at the PA trunk (circle) corresponds to coagulation necrosis of adventitia, perivascular fat and nerve fibers with intact underlying intima and media on further histological examination
