RESUMEN
As the use of endovascular aneurysm repair (EVAR) increases, anatomic constraints remain a challenge. In this case report, we describe the use of intravascular lithotripsy to facilitate EVAR in a patient with a severely calcified and stenotic aortic bifurcation. Future applications of intravascular lithotripsy could help expand the use of EVAR to patients with severely stenotic vasculature and optimize outcomes in the treatment of infrarenal abdominal aortic aneurysms.
RESUMEN
BACKGROUND: Among colorectal carcinoma patients, approximately 150 patients/year are age 25 years old or younger according to Surveillance, Epidemiology, and End Results Program statistics. Because of lack of screening in their age group, they are at risk to have more advanced disease and have been largely unstudied. OBJECTIVE: To determine outcome of colon cancer adolescent and young adult patients. METHODS: Patients under the age of 26 were retrospectively reviewed from a single institution. RESULTS: The 5-year overall survival rate from the time of the first surgery was .45 (95% confidence interval .17 to .70). The median overall survival for the cohort was 2.98 years. Patients aged 15 to 21 years had a poorer overall survival than patients aged 22 to 25 years (82% survival vs 100% at 2 years and zero vs 56% at 5 years). Five patients underwent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. Three are alive at 82, 36, and 16 weeks after hyperthermic intraperitoneal chemotherapy. CONCLUSIONS: Patients less than 21 years with nonsyndromic colorectal carcinoma may have a poorer outcome. Novel, more aggressive therapy may be necessary in these patients.
