[Percutaneous vertebroplasty for vertebral compression fracture].

BACKGROUND: Percutaneous vertebroplasty has become an option for the treatment of painful osteoporotic compression fractures in patients in whom conservative medical management has failed. AIM: This paper assessed the effectiveness and safety of percutaneous vertebroplasty in patients with focal pain caused by compression vertebral body fractures. MATERIALS AND METHODS: Over a twenty-five-month period 63 patients underwent percutaneous vertebroplasty, and ten of these patients were subsequently retreated, for a total of 73 operations on 93 vertebrae. The patients were affected by osteoporotic compression fractures (n=57) or by benign or malignant infiltrative processes (n=6). All patients were examined at discharge and thereafter to assess the level of pain and investigate possible changes in the quality of life. The mean length of follow-up was 15.2 months. RESULTS: After treatment, almost 90% of patients reported complete disappearance or significant alleviation of the pain. In 7 of 63 of the patient (11%) there were small asymptomatic leakages of cement outside the vertebral body. A substantial number of patients with osteoporosis, 19% of the study population, experienced new fractures following treatment with vertebroplasty. DISCUSSION: Our experience confirms the effectiveness of vertebroplasty to pain caused by vertebral fractures. If the indications are strictly followed, improvement of symptoms is often immediate, allowing the return of mobility, and patient satisfaction with surgery is higher. The use of appropriate systems limits the number of complications.

Mitral annular reconstruction with anterior leaflet flip-over in concomitant surgery for mitral regurgitation associated with extensive posterior annular calcification and hypertrophic obstructive cardiomyopathy.

We describe a case of severely calcified posterior mitral annulus associated with grade IV mitral regurgitation in addition to significant hypertrophic obstructive cardiomyopathy. A 70-year-old woman underwent successfully annular reconstruction with anterior mitral leaflet flip-over and mitral valve replacement with a bileaflet mechanical prosthesis combined with left ventricular septal myectomy. This technique can serve not only to cover the debrided posterior annulus, but also to eliminate left ventricular outflow tract obstruction and to keep left ventricular function by virtue of not severing ventricular-annular continuity.

Aortic valve replacement after midline-crossed internal thoracic artery grafting.

In the presence of a midline-crossed internal thoracic artery graft, a median sternotomy may jeopardize the graft and compromise hemodynamics. We report successful aortic valve replacement using a "staircase" thoracotomy and hypothermic axillary perfusion with balloon aortic occlusion in 2 men who had patent right internal thoracic artery grafts that was previously anastomosed to the left anterior descending coronary artery.

A minimally invasive approach for postoperative pancreatic fistula.

Pancreas fistula is a well-known and severe complication of pancreaticoduodenectomy. It is difficult to control with conservative therapy, inducing further complications and severe morbidity. Until now, re-operation has been the only way to resolve pancreatic fistula causing complete dehiscence of the pancreatic-enteric anastomosis (complete pancreatic fistula). Percutaneous transgastric fistula drainage is one of the treatments for pancreatic fistula. This procedure allows both pancreas juice drainage and anastomosis re-construction at the same time. This is effective and minimally invasive but difficult to adapt to a long or complicated fistula. In particular, dilatation of the main pancreatic duct is indispensable. This paper reports the successful resolution of a postoperative pancreatic fistula by a two-way-approach percutaneous transgastric fistula drainage procedure. Using a snare catheter from the fistula and a flexible guidewire from the transgastric puncture needle, it can be performed either with or without main pancreatic duct dilatation.

Clinical significance of portal venous metallic stent placement in recurrent periampullary cancers.

BACKGROUND/AIMS: We evaluate the clinical significance of portal venous expandable metallic stent (EMS) placement for patients who have malignant portal hypertension caused by recurrent periampullary cancer. METHODOLOGY: Four post-pancreatoduodenectomy patients underwent percutaneous transhepatic portal venous EMS placement because of symptoms of malignant portal hypertension: intractable ascites (2/4), growth of abnormal collateral vein (3/4), melena (2/4), gastroesophageal varix (3/4) and thrombocytopenia (2/4). They were diagnosed with having a recurrence by cytology of ascitis, computed tomography and/or tumor markers in serum. The stenosis segment was measured by percutaneous-transhepatic portography and was dilated with a balloon prestent placement. The patency of stent was confirmed using Doppler ultrasonography and enhanced computed tomography at least once a month. RESULTS: The portal venous pressure was significantly decreased from (24.5 +/- 3.92 mmH2O) to (19.5 +/- 3.87 mmH2O) and the symptoms related to portal hypertension were reduced in all patients. There were no complications related to EMS placement. All patients were alive more than a year later and two of four patients were alive more than two years without morbidity. CONCLUSIONS: Percutaneous-transhepatic portal EMS placement is a minimally invasive procedure and is a useful treatment against malignant portal hypertension caused by recurrent periampullary cancer.
