Spinal dural arteriovenous fistulas: the use of intraoperative microvascular Doppler monitoring.

Spinal dural arteriovenous fistulas are characterized by an abnormal communication between the dural branch of the radiculomedullary artery and an intradural medullary vein. Although the optimal treatment strategy is still debated, a complete interruption of the flow in the fistulas should be obtained. The authors report four cases operated on with intraoperative microvascular Doppler monitoring assistance. In all cases, microDoppler confirmed the location of the fistula and revealed an arterial spectrum on the redundant dorsal medullary veins. After the clipping of the feeder of the arteriovenous shunt, the intraoperative monitoring documented a complete disappearance of the arterial spectrum and the reappearance of the venous pattern. The ultrasonographic changes suggested the complete interruption of the fistulas. Postoperative angiography showed no residual abnormality in all patients. Doppler monitoring during surgery confirms satisfactory interruption of the arterial feeder and may prove useful where initial identification of the feeding vessel is difficult.

Performance indicators of organized cervical screening in Romagna (Italy).

The availability of published data from organized cervical screening programmes in southern Europe is scant. In the Italian area of Romagna, a first round of organized screening (based on a 3-yearly Pap smear for women aged 25-64 years) was initiated between December 1995 and January 1997 and was completed in an average of 42 months (range 36-48 months). The target population included 305 478 women. Of these, 253 949 were eligible and received a personal letter of invitation. Age-specific screening performance indicators were calculated according to standard methods. The response rate within 6 months of invitation was 49.1% (n=124 621). The total participation rate including women who presented later was 61.7% (n=156 735). The recall rate was 35.2 per 1000 of participants (n=5514). Positive cytology results were distributed as follows: atypical squamous cells of un-determined significance/atypical glandular cells of undetermined significance (ASCUS/AGUS) 40.1%, low-grade squamous intraepithelial neoplasia (LGSIL) 48.6%, high-grade squamous intraepithelial neoplasia (HGSIL) 10.7% and carcinoma 0.7%. Compliance to colposcopy follow-up was 93.4% (n=5149). The biopsy rate was 52.4% (n=2696) of patients undergoing colposcopy. The detection rate was 4.5 per 1000 of participants (n=707) for CIN2-3 and 0.5 (n=75) for invasive carcinoma. The proportion of microinvasive carcinomas was 36.0% (n=27). The positive predictive value for CIN2-3/carcinoma was 5.8% for the cytology reports of ASCUS/AGUS, 7.6% for those of LGSIL, 76.5% for those of HGSIL, and 100.0% for those of carcinoma (80.4% for combined HGSIL/carcinoma). The ratio of observed to expected (or prevalent to incident) cases of invasive carcinoma was 2.35 (95% confidence interval (CI) 1.85-2.95). In conclusion, most early results of the programme were compatible with an acceptable performance.

Isolated hemangioblastoma of the filum terminale. Case report.

The filum terminale is an exceptional location for isolated hemangioblastoma. Only five cases are reported in literature, prior to the magnetic resonance imaging era. A 57-year-old man was referred to our Department with a prolonged history of progressive back pain, particularly severe when recumbent, and recurrent unilateral sciatalgia. Computed tomography demonstrated a non-homogeneous mass at L4 level. Magnetic resonance imaging displayed earliness and homogeneous enhancement of the mass with tortuous vessels above the rostral pole of the tumour, suggesting the diagnosis of a vascular tumour. The tumour was totally removed. Histological examination confirmed the hemangioblastoma diagnosis. The case indicates that hemangioblastoma, although uncommon, must be taken into consideration in cauda equina tumour diagnosis, and also emphasises the specificity of magnetic resonance features.
