ABSTRACT
We report a case of a 45-year-old man presenting with tachycardia and palpitation. Echocardiography indicated severe tricuspid regurgitation. We suspected traumatic tricuspid damage due to high energy trauma in a motor vehicle accident 17â¯years earlier. He underwent a sternotomy, and his tricuspid valve was repaired with chordal reconstruction, indentation closure, and ring annuloplasty. The postoperative period was uneventful, and he was discharged 10â¯days after the operation. This report highlights the value of echocardiography for diagnosis of primary tricuspid regurgitation related to trauma, and the importance of early diagnosis to allow surgical intervention before irreversible damage occurs. Learning objective: Traumatic tricuspid regurgitation is a rare cardiovascular complication of blunt chest trauma. The mechanism of the tricuspid valve injury is thought to be secondary to sudden impact causing an anteroposterior compression of the right ventricle by the sternum in end-diastole. This injury is often incidentally identified or can be missed until the patient experiences symptoms of right heart failure resulting from severe tricuspid regurgitation.
ABSTRACT
Vasculopathy in patients with type 1 neurofibromatosis is known. Brachial artery aneurysms in patients with type 1 neurofibromatosis are rare, but any rupture can be extremely serious. A 56-year-old woman presented to our hospital with sudden pain in her right upper arm. Computed tomography revealed a ruptured brachial artery aneurysm, and operative reconstruction using a saphenous vein graft was performed. This is one of the few case reports of such successful revascularization using saphenous vein. The pathologic findings suggest neurogenic tumor invasion, and end-to-side anastomosis was effective in avoiding hemorrhagic complications.
