Combined treatments with microballoon catheters and multiple cryoablation probes for shoulder-subclavian soft tissue hemangiopericytoma: A case report

We describe a case of a 65-year-old woman affected by hemangiopericytoma/solitary fibrous tumor of the right shoulder—subclavian region. Hemangiopericytoma/solitary fibrous tumor is a rare tumor of uncertain malignancy. She reports shoulder pain and inability to abduct the arm and elevate the shoulder. Imaging showed erosion of the scapula. The patient underwent 5 sessions of “on demand” embolization in the previous 2 years scheduled for recurrence of symptoms-swelling of tissues. Further 2 treatments were achieved through embolization via 2 different microballoon catheter combined with percutaneous cryoablation with 5 probes. Images after the treatment demonstrate a marked reduction in the hypervascularized area and an increase in the necrosis area. So, this combined treatment is safety and reproducible also in extrahepatic tissue

Bilateral renal artery stenosis treated with drug-eluting balloon angioplasty in unique treatment

Renal artery stenosis commonly manifests with hypertension refractory to medical treatment. We report a case of renal artery stenosis occurring in a 19-year-old female patient who presented with extremely high blood pressure and bilateral renal stenosis at the duplex ultrasound. Renal angiography confirmed the bilateral and irregular stenosis due to fibromuscular dysplasia, associated to extent collaterals suppling the poststenotic right renal artery. Therefore, angioplasty with drug-eluting balloon was performed in order to obtain a good vessel patency and to improve patency in the long term follow-up. After the endovascular treatment the blood pressure improved markedly, maintaining this result at 12 months follow-up at clinical examination and duplex ultrasound.
