We have assessed the final strength of the deltoid in 121 patients who had repair of isolated or combined lesions of the axillary (circumflex) nerve and were available for statistical analysis. Successful or useful results were achieved in 85% after grafting of isolated lesions. The strength was statistically better when patients had grafting of the axillary nerve within 5.3 months from the tim...

A 74-year-old man was diagnosed with aortic root aneurysm and two-vessel coronary disease. Echocardiographic assessment revealed an enlarged sinus of Valsalva 60 mm in diameter with mild aortic regurgitation. Florida sleeve repair was performed using a vascular graft combined with coronary artery bypass grafting. The postoperative course was uncomplicated and follow-up echocardiographic evaluat...

Diabetes mellitus, by virtue of myriad processes, including its effects reducing vascular nitric oxide and prostacyclin production and increasing endothelin, angiotensin II, tissue factor activity, and platelet activity (1,2), wreaks havoc on coronary and other arteries, leading to diffuse and often unstable coronary atherosclerosis. It is also a risk factor for poor outcomes after both percuta...

Aneurysmal bone cyst (ABC) is a benign, tumor-like, highly vascular, locally aggressive, and relatively rare osteolytic lesion of unknown etiology [1]. Treatment options for aneurysmal bone cysts are simple curettage with or without bone grafting, complete excision, embolization, radiation therapy, or a combination of these modalities [2,3]. Radical surgical excision should be the goal of surge...

A 60-year-old man visited the outpatient clinic due to one month of recurrent exertional chest pain. Eleven years earlier he had undergone off-pump coronary artery bypass grafting using bilateral internal thoracic artery (ITA) Y-composite grafts based on the left ITA. Preoperative coronary angiography showed patent distal graft anastomoses and visualized the left ITA retrogradely. The arch aort...

BACKGROUND This study examined the ability of cryopreserved whole ovine ovaries to resume function in vivo following autotransplantation. METHODS Swaledale ewes had their left ovaries removed and either perfused but not cryopreserved (n = 4; control), or perfused and cryopreserved (n = 8; cryopreserved) before autotransplantation sub-cutaneously to the neck by microvascular anastomosis. Right...

Blood flow in end-to-side autogenous or prosthetic graft anastomoses is of great interest to biomedical researchers because the biomechanical force profile engendered by blood flow disturbances at such geometric transitions is thought to play a significant role in vascular remodeling and graft failure. Thus, investigators have extensively studied anastomotic blood flow patterns in relationship ...

The failure rate for vascular interventions (vein bypass grafting, arterial angioplasty/stenting) remains unacceptably high. Over the past two decades, researchers have applied a wide variety of approaches to investigate the primary failure mechanisms, neointimal hyperplasia and aberrant remodeling of the wall, in an effort to identify novel therapeutic strategies. Despite incremental progress,...

Endovascular stent grafting (EVSG) is a minimally invasive alternative to open repair of thoracic aortic aneurysms. It is useful in the treatment of thoracic aneurysms, dissections, and ruptures. Currently, the incidence of thoracic aortic aneurysms is 6:100,000 people. Comorbidities often include hypertension, coronary artery disease, chronic obstructive pulmonary disease, peripheral vascular ...
