Chronic occlusion mimicking agenesis of the inferior vena cava in patients with iliofemoral deep vein thrombosis.

Agenesis of the inferior vena cava (IVC) has been described as a risk factor for proximal deep vein thrombosis (DVT). We have described the cases of two patients with iliofemoral DVT who had developed post-thrombotic syndrome (PTS). Both cases were misdiagnosed as IVC agenesis on routine imaging; however, an IVC lumen was successfully identified and recanalized during venography with significant improvement in the patients' PTS symptoms. Patients with iliocaval segment DVT with a misdiagnosis of IVC agenesis might have chronic occlusion imitating agenesis. It is worthwhile to attempt percutaneous recanalization of the IVC lumen in these patients and restoring normal venous flow to prevent the development of PTS.

Multicentre Covariate Adjustment Analysis of Short-Term and 5-Year Outcomes after Endovascular Repair according to Sex.

BACKGROUND: Several studies have reported worse outcomes in women compared to men after endovascular aneurysm repair (EVAR). This study aimed to evaluate sex-specific short-term and 5-year outcomes after EVAR. METHODS: A total of 409 consecutive patients underwent elective EVAR from 2004 to 2017 at two tertiary hospitals in Western Australia. Baseline, intraoperative, and postoperative variables were examined retrospectively according to sex. The primary outcome was 30-day mortality (death within 30 days after EVAR). Secondary outcomes were 30-day composite endpoint, length of stay after EVAR, 5-year survival, freedom from reintervention, residual aneurysm size after EVAR, and major adverse event rate at 5-year follow-up. RESULTS: A cohort of 409 patients, comprising 57 women (14%) and 352 men (86%), was analysed. Female patients were older (median age, 76.8 versus 73.5 years, p=0.017). Male patients were more likely to be past smokers (40.9% versus 22.8%, p=0.017). Male patients were more likely to be past smokers (40.9% versus 22.8%, p=0.017). Male patients were more likely to be past smokers (40.9% versus 22.8%, p=0.017). Male patients were more likely to be past smokers (40.9% versus 22.8%, p=0.017). Male patients were more likely to be past smokers (40.9% versus 22.8%, p=0.017). Male patients were more likely to be past smokers (40.9% versus 22.8%, p=0.017). Male patients were more likely to be past smokers (40.9% versus 22.8%. CONCLUSION: This study found no significant differences in 30-day and 5-year outcomes between female and male patients treated with EVAR, implying that EVAR remains a safe treatment choice for female patients.
