Objective: The study was designed to evaluate the safety, efficacy, and usefulness of the performance of percutaneous radiologic (PRG) and endoscopic (PEG) gastrostomy.

Materials And Methods: This study involved a retrospective review of 182 percutaneous gastrostomy procedures (68 PRG, 114 PEG) performed over a 3-year period. Parameters analyzed included technical success, procedure duration, anesthetic requirements, incidental findings on endoscopy, and complications.

Purpose: To determine whether acute cervical spine injury represents a risk factor for complications from prophylactic placement of current generation Greenfield inferior vena cava (IVC) filters.

Materials And Methods: A retrospective chart review performed during a 7-year period identified 11 patients with acute cervical spinal cord injuries who underwent prophylactic Greenfield IVC filter insertion. Specific complications evaluated included symptomatic pulmonary embolism (PE), migration, filter base diameter changes, caval perforation, and thrombosis.

Objective: The aims of this study were to determine the reliability of the high-resolution CT (HRCT) appearance of the lung parenchyma in distinguishing patients with chronic pulmonary thromboembolism (CPTE) from those with other pulmonary diseases and to compare HRCT with radionuclide scanning.

Subjects And Methods: Sixty-seven patients for whom HRCT scans were available for review were included in the study. Twenty-eight had proven pulmonary arterial hypertension (PAH), 17 cases of which were caused by CPTE, and 39 had other pulmonary abnormalities.

Purpose: To assess the efficacy and safety of percutaneous catheter drainage combined with alcohol sclerosis in the treatment of postoperative lymphoceles.

Patients And Methods: Thirteen patients with 14 postoperative symptomatic lymphoceles were treated. Drainage catheters were inserted under ultrasound (n = 13) or computed tomographic (n = 1) guidance.

Rationale And Objectives: We evaluated the accuracy of contrast-enhanced magnetic resonance (MR) angiography in demonstrating the findings of chronic pulmonary thromboembolism (CPTE) compared with conventional pulmonary angiography.

Methods: We examined 18 patients with CPTE proved by conventional pulmonary angiography and 16 healthy control patients. T1-weighted and single-breathhold, two-dimensional multiplanar spoiled gradient-recalled pulmonary images were obtained after injection of gadopentetate dimeglumine.

Purpose: To evaluate the effectiveness and safety of radiologic, percutaneous endoscopic (PEG), and surgical gastrostomy.

Materials And Methods: This project involved 5,752 patients (837 patients underwent radiologic gastrotomy; 4,194, PEG; and 721, surgical gastrostomy). Seventy-two (47 male, 25 female; age range, 12-94 years) underwent gastrostomy within 1 year in this series (radiologic gastrostomy, n = 33; PEG, n = 35; surgical gastrostomy, n = 4).

Purpose: To determine the cause of symptoms and efficacy of transcatheter therapy in a series of patients with dialysis grafts and hand pain referred for arteriography.

Materials And Methods: Thirteen patients with 14 hemodialysis grafts underwent arteriography for possible hand ischemia. The sites of proximal graft anastomosis were the distal radial artery (n = 6) and the mid- to distal brachial artery (n = 6).

Transcatheter treatment of thrombosed hemodialysis access grafts.

AJR Am J Roentgenol

April 1995

Department of Radiology, University of California, San Diego Medical Center 92103-8756, USA.

Thrombosis of access grafts is a frequent problem for patients being treated with long-term hemodialysis. Transcatheter techniques have recently been used in the primary management of failed dialysis grafts. This article reviews current methods for transcatheter treatment.

Purpose: To evaluate the effectiveness of intravenous and intrathrombic injection of the thrombin inhibitor argatroban during pulse-spray pharmacomechanical thrombolysis (PSPMT) in experimental venous thrombosis.

Materials And Methods: Clots were produced in the inferior vena cava in 52 rabbits by placement of steel coils and balloon injury to the vessel wall. Two days later, clots were treated with PSPMT.

Objective: Although fast spin-echo images and slower spin-echo images have similar contrast characteristics, the two techniques have not yet been shown to be equivalent in all aspects of brain imaging. To determine if the two sequences are equivalent, we compared detection of white matter lesions, image quality, and artifact degradation on fast spin-echo and spin-echo proton density-weighted and T2-weighted MR images of the brain in prospectively selected patients who were seropositive for HIV.

Subjects And Methods: Fast spin-echo and spin-echo MR images of the brain were obtained in 153 consecutive subjects.

Cystosarcoma phyllodes of the prostate is a rare, relatively benign sarcoma of the prostate. We describe the magnetic resonance imaging findings in an unusual case of cystosarcoma phyllodes which resulted in extensive local recurrence and sarcomatous degeneration. Although uncommon, radiologists should be aware of the existence of cystosarcoma phyllodes of the prostate.

Extraspinal abnormalities detected on MR images of the spine.

AJR Am J Roentgenol

March 1994

Department of Radiology, University of California, San Diego Medical Center 92103-8756.

Surface-coil MR imaging of the spine is one of the most commonly performed MR imaging procedures. As the spine is the region of interest in these studies, extraspinal abnormalities may be overlooked. Such lesions can be difficult to perceive because they are out of the area of interest or distant from the surface coil.
