While ultrasonography is widely performed prior to biopsy, colour Doppler examination is often used only to discover post-biopsy complications. Aim of this paper was to evaluate the usefulness of colour Doppler examination in planning the optimal site of puncture for renal biopsy. Present analysis includes 561 consecutive percutaneous renal biopsies performed from the same operator. Until August 2000 332 biopsies were performed after a preliminary ultrasonography (Group A). From September 2000, 229 patients underwent even a preliminary colour Doppler study (Group B). Postbioptic bleeding were categorized as minor (gross hematuria or subcapsular perinephric hematoma < 4 cmq of greater diameter) or major (hematoma >4 cmq of greater diameter; requiring blood transfusion or invasive procedures; leading to acute renal failure, urine tract obstruction, septicaemia, or death). Major complications were seen in 2.1% in Group A while in Group B only one case was reported (0.43%). Minor clinically significant complications occur in 7.8% in Group A and in 3.4% of cases of Group B. Colour Doppler reduced drastically the incidence of complications observed before the introduction of routine colour Doppler examination prior to biopsy. In our opinion, these data support the use of preliminary colour Doppler study when a biopsy is planned.

Introduction: Colour Doppler sonography is a well-established widely available,noninvasive, cost effective and a reliable method for assessing cerebrovascular circulation.It has become a valuable completion of the sonographic workup in patients with cerebralischaemia and infarction. Its accuracy is close to angiography. Objectives: To determine thefrequency of significant carotid artery stenosis in patients of cerebral ischaemia/stroke and itscharacterized sonographic appearance of plaque. Study Design: Cross sectional study, basedon nonprobability convenience sample technique. Setting: Department of Radiology, CombinedMilitary Hospital Lahore, using Colour and Power Doppler Ultrasound machine ALOKA SSD-5500. Period: 14 October 2006 to 15 March 2007. Methodology: Total of 50 diagnosed patientsof either gender, aged 30 to 70 years with cerebral ischaemia and stroke were included in thestudy. Carotid Doppler examination was conducted in each patient and findings were recorded.Results: Among 50 patients who underwent carotid Doppler examination for diagnosis ofclinically significant carotid artery stenosis, 35 patients had carotid plaques. 08 patients werediagnosed to have more than 70 % stenosis, 07 patients with more than 50 % and 20 patientsless than 50 % carotid artery stenosis. 15 patients did not show any carotid artery disease.12 patients had bilateral stenosis while 23 had unilateral disease. Mean age of the patientswith and without carotid artery disease was 52 ± 7.87 years. Conclusion: Majority of patientswith Cerebral ischemia/stroke showed carotid artery stenosis on colour Doppler ultrasound.Common age group who developed cerebral ischemia/stroke was above 50years.

Haemodynamic Changes

Colour Doppler ultrasound is a new diagnostic method in neuroradiology allowing the non invasive imaging of parenchymal and vascular structures in adults as in children through the intact skull. In particular, this study describes the use of colour Doppler US in children with intracranial arteriovenous malformations to determine its value in the evaluation of haemodynamic changes in cerebral vessels. To test the hypothesis that colour Doppler US analysis of spectral waveforms can be considered an indirect measurement of volume flow in major arteries and veins, we performed 13 colour Doppler US examinations on 4 children with vein of Galen malformations, 2 with parenchymal arteriovenous malformations and 7 children with facial angiomas, before the endovascular treatment, immediately thereafter and after a short time. Peak systolic and end-diastolic flow velocities, resistive index and pulsatility index, quantitative expression of cerebral blood flow, was attempted, while qualitative parameters such as blood flow direction, spectral waveform morphology and spectral broadening were not considered useful in the study. Colour Doppler US performed after endovascular treatment showed: a decrease of main feeder flow velocity and an increased pulsatility index and/or resistive index (as indirect measurement of increased peripheral stream resistance); the presence of echogenic foci within blood vessels, in the nidus or in the vein of Galen, representing embolisation materials or thrombi, such as residual color flow in the same embolised vascular territories; decreased blood flow velocity and spectral broadening in draining veins, indicating an incomplete occlusion of fistulas. In one case of vein of Galen malformation, we performed colour Doppler US three days after the embolisation, showing the occlusion by thrombi of the vein of Galen and of the draining veins. Colour Doppler US can be considered a valuable method for non-invasive haemodynamic assessment of blood flow in cerebral arteriovenous malformations. With this procedure, allowing serial examinations with unlimited repeatability and by using portable equipment at the patient' bedside, it is possible to monitor haemodynamic changes after embolisation. This limits the use of more invasive procedures such as CT, MR and angiography and the relatively large amounts of contrast material and radiation dose.

Bilateral Sensorineural Hearing Loss

Objectives: We report a case of bilateral sudden sensorineural hearing loss (SSHL) in a patient suffering from chronic venous cerebrospinal insufficiency (CCSVI). Methods: Audiometric testing confirmed bilateral sensorineural hearing loss with hypoexcitability to caloric stimulation on the left side and echo-colour Doppler examination showed abnormal cerebral venous deficiency. Results: The patient's condition improved after 15 days following medical treatment. Conclusions: CCSVI may explain the anatomical background which provides a predisposing factor for SSHL although further studies are needed to verify whether this observation is casual or coincidental.
