ABSTRACT
Tortuous vasculature is a common reason for failure to stabilize a guiding catheter in an appropriate position and is associated with a higher incidence of vascular complications. In such a case, the guiding catheter often buckles into the aorta during an attempt to place the balloon or stent. In this report, we used the buddy wire technique to support the guiding catheter, and we passed through the vertebral artery origin stenosis with the help of a microcatheter-microguidewire combination which enabled stent deployment. We kept the buddy wire through the guiding catheter throughout the procedure and the 6F guiding catheter allowed passages of both buddy wire and stent system.

OBJECTIVES: Epidemiological studies have shown that the incidence of intracerebral haemorrhage (ICH) is high in patients with low cholesterol levels. The aim of this study was to investigate the correlation between ICH and low cholesterol in cases of primary ICH. MATERIAL AND METHODS: Two hundred and fifty-nine patients with primary intracerebral haemorrhage and 137 healthy individuals were included in this study. Patients with prior cerebrovascular accident, secondary ICH, hereditary lipid metabolism disorders, thyroid diseases and those using lipid-lowering drugs were excluded. In all subjects, cholesterol levels were measured after 12 h of fasting. RESULTS: Mean cholesterol levels were 205.8 +/- 51.4 mg/dl in the ICH group and 230.2 +/- 38.9 mg/dl in the control group. Mean cholesterol levels of patients were significantly lower than the controls (P < 0.000). In ICH group, the frequency of patients who had very low cholesterol levels was significantly higher than the control group (P < 0.000). CONCLUSIONS: Individuals with lower cholesterol levels have an increased risk of ICH. Therefore, before treatment with statins, clinicians must be aware of the possible ICH risk.
