CONTEXT In some cases, synchronous superior mesenteric-portal vein resection can be performed during pancreatic resection for cancer. The reconstruction technique is usually primary anastomosis; in only a few cases is an autologous vein graft needed. CASE REPORT We report a case of reconstruction of the superior mesenteric-portal vein with a splenic vein autograft in a patient affected by pan...

BACKGROUND Dilatation of the pulmonary autograft is a major drawback of the Ross procedure and it is the leading cause for reoperation in these patients. CASE PRESENTATION In this report we describe 3 cases reports, each one with a different outcome, of patients that underwent the Ross procedure. CONCLUSIONS In order to prevent any lethal or non-lethal complications of the pulmonary autogra...

Background Quadrupled (4-strand) hamstring tendon autografts are commonly used in anterior cruciate ligament (ACL) reconstruction, but there is significant variability in their diameter. The 5-strand hamstring autograft has been used as a means of increasing the graft diameter in patients with undersized hamstring grafts. Purpose To report the outcomes of primary ACL reconstruction using 5-st...

BACKGROUND The effect of low-dose gamma irradiation on healing of soft tissue allografts remains largely unknown. HYPOTHESIS The authors hypothesized that soft tissue allograft healing to bone would be delayed compared with that of autograft tissue and that low-dose (1.2 Mrad) gamma irradiation would not affect the healing response of allograft tissue after anterior cruciate ligament (ACL) re...

OBJECTIVE Significant dilation of the pulmonary autograft is problematic after the Ross operation and may require reoperation. Pulmonary autograft remodelling occurs in response to the immediate rise in pressure and consequently wall stress. Stress-strain response of the pulmonary root plays an important role in understanding autograft function and remodelling following the Ross procedure. Howe...

A nterior cervical discectomy and fusion (ACDF) has been performed with various techniques and devices for many years. Autologous iliac crest grafts were initially used for the Cloward and Robinson and Smith techniques, but because of iliac crest graft site complications (eg, pain, infection, fracture, dystrophic scarring), the procedure was generally superseded by allograft implants. These imp...

INTRODUCTION The Ross root replacement is the only technique that guarantees long-term viability of all the component parts of the root. The normal aortic root performs extremely sophisticated functions which are closely linked to its structure, dynamics and viability. This has been shown to translate into clinically-relevant endpoints, such as survival and quality of life. The insertion of the...

Using a canine critical-size segmental defect model, a two-phased study was undertaken to evaluate the healing efficacy of demineralized bone and cancellous chips (DBM-CC) enriched with osteoprogenitor cells using a Selective Cell Retention (SCR) technology. The goals of this study were: 1) to determine the bone-healing efficacy of SCR-enriched grafts versus autograft, and 2) to assess the valu...

The objective of this study was to investigate the bone regeneration of a “gold standard” (autograft) from iliac crest associated with cellular therapy in rabbits. A bone defect was created with 10x5x5mm in 28 rabbit mandibles. The control group animals (n=14) were repaired with autograft of iliac crest and the experimental group animals (n=14) received iliac crest autograft in association with...
