RESUMO
BACKGROUND: The aim of this study is to evaluate central venous stenosis (CVS) etiologies and presentation within a vascular surgery practice. We evaluated endovascular treatment modalities and the patency rates of our interventions. METHODS: Five-year retrospective review of endovascular intervention for CVS. Patient demographics, medical comorbidities, and variables were collected including etiology, indwelling device, previous upper extremity (UE) deep venous thrombosis, long-term UE indwelling device (defined as >30 days), malignancy status, hypercoagulable disorders, history of radiation or mediastinal fibrosis or masses, and anticoagulation and/or antiplatelet therapy. Follow-up variables included symptoms, imaging, and anticoagulation and/or antiplatelet utilization. Living patients without recent follow-up were contacted with a telephone survey regarding current symptoms. Patency was evaluated by imaging or clinically by recurrence of signs or symptoms through January 2016. RESULTS: A total of 61 patients underwent attempted endovascular CVS interventions from January 2007 to 2013. Forty-seven (83%) patients had successful interventions. There were 22 (36%) end-stage renal disease (ESRD) patients. The primary etiology in 79% of patients was benign CVS secondary to an indwelling device. Eighty-nine percent of the interventions were primary angioplasty (PTA). The overall primary patency rates at 6, 12, and 24 months were 49%, 34%, and 24%, respectively. Secondary patency rates at 6, 12, and 24 months were 97%, 93%, and 88%, respectively. There were no statistical differences in demographics or outcomes in patients treated successfully with PTA or those requiring stenting. There was no statistical difference in the patency rates between ESRD and non-ESRD patients. Previous interventions were not a predictor of loss of patency. CONCLUSIONS: Our study supported the rising trend of benign CVS predominantly secondary to indwelling devices. We demonstrated acceptable secondary patency with PTA alone. This study adds further support for a primary angioplasty strategy in treating benign CVS. The optimal endovascular treatment for benign CVS is still undefined.

BACKGROUND: The incidence of rectal cancer in younger patients continues to increase. Because most of these patients do not meet criteria for routine colorectal cancer screening, diagnosis may be delayed, potentially resulting in adverse outcomes. The aim of this study was to determine whether patients under the age of 50 years with rectal cancer have a delay in diagnosis and treatment leading to a worse overall prognosis. METHODS: A case control study of patients diagnosed with rectal adenocarcinoma in an academic medical center from 1997 to 2007 under 50 years of age were matched 1:1 to randomly selected patients over the age of 50 years by sex and date of diagnosis. Time to diagnosis, time to treatment, staging of the American Joint Committee on Cancer, and 5-year overall survival were compared. RESULTS: The overall time to treatment from symptom onset was 217 days for patients under the age of 50 years versus 29.5 days if over 50 years of age (P < .0001). The primary delay occurred between the onset of symptoms and presentation to the initial physician. There was no difference in stage at the time of diagnosis or 5-year survival (64% vs 71%, P = .39 and P = .54, respectively). CONCLUSIONS: Patients with rectal cancer under the age of 50 years have symptoms for a considerable period of time before seeking medical care and are referred in less timely manner to specialists. However, the delay in diagnosis did not adversely impact stage on presentation or 5-year survival.
