Interventional radiology in the management of renal vascular injury: A prospective study.

Introduction: Endovascular and percutaneous interventions are promising alternatives to surgical management of traumatic renal injuries and often avert the need for nephrectomies. In this study, we aimed to evaluate the role of interventional radiology and angiographic interventions in the management of renal vascular injury.

Materials And Methods: Our prospective study was performed over a period of 6 months.

Approach-based techniques of CT-guided percutaneous vertebral biopsy.

Magnetic resonance imaging (MRI) plays an important role in the characterization of vertebral lesions. Even if latest improvements in MRI permit to understand and suspect the nature of vertebral lesions and positron emission tomography computed tomography (PET-CT) gives information about lesion metabolism, biopsy is still needed in most cases. CT-guided percutaneous vertebral biopsy is a minimally invasive, safe and accurate procedure for definitive tissue diagnosis of a vertebral lesion.

Magnetic resonance imaging - A troubleshooter in obstetric emergencies: A pictorial review.

The application of magnetic resonance imaging (MRI) in pregnancy faced initial skepticism of physicians because of fetal safety concerns. The perceived fetal risk has been found to be unwarranted and of late, the modality has attained acceptability. Its role in diagnosing fetal anomalies is well recognized and following its safety certification in pregnancy, it is finding increasing utilization during pregnancy and puerperium.

Midtrimester spontaneous torsion of unruptured gravid rudimentary horn: Presurgical diagnosis on magnetic resonance imaging.

Unicornuate uterus with rudimentary horn occurs due to failure of complete development and partial fusion of one of the Müllerian ducts. Pregnancy in a non-communicating rudimentary horn is extremely rare, with a reported incidence of 1 in 76 000-150 000 pregnancies, and usually terminates in rupture during the first or second trimester. Clinical diagnosis of rudimentary horn pregnancy in a woman with history of normal vaginal delivery in prior gestations is difficult.

A single institutional experience of conversion of non-tunneled to tunneled hemodialysis catheters: a comparison to de novo placement.

Purpose: To compare the outcomes of conversion of non-tunneled to tunneled hemodialysis catheters with de novo placement of tunneled catheters and to determine the effect of time to conversion of non-tunneled to tunneled catheters on the incidence of complications.

Materials And Methods: A retrospective data analyses was performed on 1,154 patients who had de novo placement of tunneled hemodialysis catheters (control group) and 254 patients who underwent conversion of non-tunneled to tunneled catheters (study group). The outcomes including technical complications, infection, and catheter dysfunction were compared between the two groups.
