Arteriovenous malformation with pseudoaneurysm on the left upper limb.

A 61-year-old woman developed a pulsatile mass on the left upper limb and was diagnosed with arteriovenous malformation with pseudoaneurysm. A two-stage operation including ligation and resection of the aberrant branches and subsequent resection of the mass with revascularization was performed. Histological analysis suggested arteriovenous malformation and pseudoaneurysm.

Successful one-stage operation for type B acute intramural hematoma with descending aortic rupture.

A 76-year-old man who complained of back pain was referred to our hospital. Computed tomography revealed an intramural hematoma with a descending aortic rupture. Total arch replacement with the frozen elephant trunk technique and thoracic endovascular aortic repair was performed emergently in one stage.

The interference with transapical transcatheter aortic valve implantation by the anterior chordae tendineae preserved at previous mitral valve replacement.

Preserved anterior chordae tendineae is a possible risk factor for disturbing delivery of a transcatheter heart valve. Inserting a sheath just below the aortic valve for delivery of the transcatheter heart valve might be proposed as an alternative to avoid the chordae tendineae.
