OBJECTIVE Our objective was to determine whether multidetector CT (MDCT) angiography is an accurate and reliable method of revealing atheroocclusive disease of the aortoiliac system and the lower extremities compared with digital subtraction angiography (DSA). SUBJECTS AND METHODS Forty-one patients with ischemic legs underwent both MDCT angiography and(More)
BACKGROUND Coincidence imaging of low-abundance yttrium-90 (90Y) internal pair production by positron emission tomography with integrated computed tomography (PET/CT) achieves high-resolution imaging of post-radioembolization microsphere biodistribution. Part 2 analyzes tumor and non-target tissue dose-response by 90Y PET quantification and evaluates the(More)
UNLABELLED Compliance with radiobiologic principles of radionuclide internal dosimetry is fundamental to the success of (90)Y radioembolization. The artery-specific SPECT/CT partition model is an image-guided personalized predictive dosimetric technique developed by our institution, integrating catheter-directed CT hepatic angiography (CTHA),(More)
OBJECTIVE The purpose of our study was to evaluate the efficacy of the perioperative placement of occlusion balloons within the internal iliac arteries in reducing intraoperative blood loss and transfusion requirements during cesarean delivery for women with placenta accreta or its variants. MATERIALS AND METHODS Over a 30-month period, 11 patients with(More)
BACKGROUND Yttrium-90 (90Y) positron emission tomography with integrated computed tomography (PET/CT) represents a technological leap from 90Y bremsstrahlung single-photon emission computed tomography with integrated computed tomography (SPECT/CT) by coincidence imaging of low abundance internal pair production. Encouraged by favorable early experiences, we(More)
A patient presented with iliofemoral deep vein thrombosis, a small pulmonary embolism, and a paradoxic embolus to the axillary artery resulting from a patent foramen ovale (PFO). As prophylaxis against further paradoxic emboli while awaiting percutaneous PFO closure, a Günther Tulip inferior vena cava (IVC) filter was implanted. To prevent incorporation of(More)
STUDY TYPE Therapy (case series). LEVEL OF EVIDENCE 4. OBJECTIVE To present our institution's experience of selective embolization of renal angiomyolipomas with alcohol and the long-term follow up data. PATIENTS AND METHODS This retrospective study included 34 patients treated between October 1997 and October 2007 (29 women and five men, mean age 44(More)
PURPOSE To compare the efficacy and safety of cutting balloon angioplasty (CBA) versus high-pressure balloon angioplasty (HPBA) for the treatment of hemodialysis autogenous fistula stenoses resistant to conventional percutaneous transluminal angioplasty (PTA). MATERIALS AND METHODS In a prospective, randomized clinical trial involving patients with(More)
PURPOSE To evaluate our experience of limb salvage with bare nitinol stent enabled recanalization of long length occlusions of superficial femoral artery (SFA) and adjacent proximal popliteal artery (PPA) in diabetic patients. METHODS A total of 573 patients underwent 842 lower limb interventions from August 2006 to September 2008 at our institute. A(More)
BACKGROUND The purpose of the present study was to report the authors' experience of surgically treating eight limbs in six patients for popliteal artery entrapment syndrome (PAES), over a 10-year period. METHODS From 1995 to 2004, six patients (eight limbs) underwent surgery for PAES at a single institution. The patients' data were collected(More)
