This is a report of a case of acute-on-chronic inferior vena cava thrombosis 10 years following blunt abdominal trauma from a motor vehicle collision. Although more common risk factors for this pathology include anatomical variation or the long-standing presence of an inferior vena cava filter, history of blunt abdominal trauma serves as a rare etiology. Fewer than 20 cases of inferior vena cava thrombosis following blunt abdominal trauma have been reported in the literature, and most describe a presentation within weeks of inciting trauma. The lengthy time to diagnosis and acute-on-chronic presentation given substantial reconstitution of circulation by collateral veins make this case unique in the literature.

Background CRS with HIPEC is a complex operation that has shown survival benefit in patients with a variety of primary and metastatic peritoneal surface malignancies. While optimal oncologic and perioperative outcomes have been defined by expert consensus and demonstrated at university-affiliated, academic centers, similar results have never been presented from a non-university-affiliated, community center in the literature to date. Methods All cases of CRS with HIPEC performed at a non-university-affiliated, community center were retrospectively reviewed and analyzed. Oncologic and perioperative outcomes were compared Chicago Working Group benchmarks and with results from university-affiliated, academic centers recently published in high-impact-factor, peer-reviewed journals. Results All 112 cases completed over 5 years were reviewed. 3 were excluded from analysis since they were palliative HIPEC procedures for distressing ascites-related symptoms only without CRS. A wide variety of tumors were treated. Average PCI was 18±9.1. Median PCI was 14. CC 0–1 was achieved in 89% of patients. Average length of stay was 11.6±9.3 days. Serious perioperative morbidity, defined as a Clavien-Dindo Grade III or IV complication, was observed in 22% of patients. The frequency of major complications decreased after the first year. There were no perioperative deaths. Conclusions Optimal oncologic and perioperative outcomes of CRS and HIPEC are attainable at a non universityaffiliated, community center. A multidisciplinary team and high clinical volume are necessary to obtain these results.

Cystic adventitial disease (CAD) is a rare, benign disease of blood vessels which most commonly affects the popliteal artery. Less than 50 cases of CAD affecting veins have ever been described in the literature to date. We report the case of a 56-year-old woman who presented with unilateral lower extremity swelling and varicosities due to CAD of her common femoral vein. Resection and reconstruction with a venous interposition graft, employing a polytetrafluoroethylene graft and arteriovenous fistula in order to maintain venous bypass patency, were performed successfully. The patient recovered well without any evidence of recurrence or postoperative complications.
