BACKGROUND Aneurysms of the visceral arteries are rare but potentially lethal lesions. We describe a case of a successful endovascular exclusion of a hepatic artery aneurysm in a patient that suffered from chronic abdominal pain. CASE REPORT A 68-year old man presented with chronic abdominal pain that had existed for 10 months. A diagnostic contrast-enhanced CT scan showed an 18 mm atheroscle...

The present report demonstrates a clinical procedure to restore an edentulous area with severe bone destruction using ridge augmentation and implant placement. Titanium-reinforced, expanded polytetrafluoroethylene (ePTFE) membrane and tenting screws combined with a mixture of autogra and allogra (rate 50%: 50%) were used for guided bone regeneration (GBR). A two-stage surgery was performed to r...

High blood pressure (hypertension) is implicated in the development of atherosclerosis. Blood vessels are constantly subjected to stretch due to blood pressure and changes in stretch usually instigate adaptive vascular remodeling, including abnormal growth and proliferation of vascular smooth muscle cells (VSMCs) as well as extracellular matrix (ECM). In this experiment, we used bovine aortic e...

A 28-year-old German-Caucasian man arrived with deep vein thrombosis DVT, pain, oedema and rubor of right lower limb and drug abuse. The US Doppler imaging showed an autogenic AV fistula and false aneurysm of the right superficial femoral artery and femoral vein. The CT imaging showed additional closing of the left external iliac artery and common femoral artery, and of the distal and middle pa...

A pointed, narrow and exaggeratedly upturned nasal tip and concave dorsal profile can give the nose an unnatural and artificial appearance that is the unmistakable hallmark of plastic surgery. As a result of changes in social attitudes, noses that have evidently been operated on are no longer acceptable and requests are made for correction. While a more natural dorsal profile can be obtained wi...

We have been developing a pulmonary circulatory assist device using shape memory alloy fibres for Fontan circulation. It consisted of several shape memory alloy fibres, which covered the ePTFE conduit circumferentially. We designed the sequential motion control system for pulsatile flow generation for sophisticated pulmonary hemodynamics. In order to achieve physiological pulsatile flow assista...
