Clinical evaluation of stenosis of the carotid bifurcation with magnetic resonance angiographic techniques.

We evaluated the images of 60 carotid artery bifurcations in 31 patients suspected to have carotid artery disease who underwent invasive carotid angiography and combined two-dimensional, phase-sensitive and a gradient-echo magnetic resonance angiography. The phase scans consisted of seven serial projections that were obtained at 20 degrees intervals (11.0 minutes) around the carotid bifurcation; the gradient-echo (GRASS) scans were composed of 11 axial images (2.4 minutes) acquired through the bifurcation. The two magnetic resonance angiographic techniques yielded complementary pieces of information and were used together to compare magnetic resonance angiography with invasive angiography. Comparison of magnetic resonance and invasive angiograms of the 60 carotid arteries shows that the sensitivity (86%) and specificity (92%) of the magnetic resonance angiographic techniques we used to diagnose clinically significant carotid stenosis approach but do not reach those of invasive angiography.

Vertebrobasilar dolichoectasia: assessment using MR.

We evaluated six patients with vertebrobasilar dolichoectasia (VBD) comparing clinical presentation with magnetic resonance (MR) and computed tomography (CT) imaging. MR diagnosed the condition as well as CT in all cases, but proved superior to CT in delineating the anatomical relationship of the vessels to the neural structures. MR proved especially useful in cases of VBD-associated hydrocephalus and posterior fossa masses. A coexisting tumor was diagnosed by MR in one case.

Management of perirenal hematoma found during laparotomy in patient with multiple injuries.

The medical records of 158 patients with perirenal hematoma found during laparotomy for intra-abdominal injury from external trauma were analyzed. Small perirenal hematomas were usually associated with renal contusions and renal artery thrombosis, while large perirenal hematomas often were present with large renal lacerations, renal ruptures, and renal pedicle injuries with rupture of the renal vein, renal artery, polar artery, or branch of the renal artery. The management of the perirenal hematoma found during laparotomy depends on the degree of the underlying renal injury and not on the size or extent of the perirenal hematoma.

Ecological transition: using Bronfenbrenner's model to study sexual identity change.

Bronfenbrenner's (1979) ecological transition model provides a framework to study coming out in lesbians. The model takes into account activities such as sexual behavior, perceptions of the behavior, and social context in which behavior takes place. The importance of context makes this model useful in identifying possible connections between sexual identity alterations and larger social forces. Interventions based on this framework can reduce stress and promote health during coming out.
