RESUMO
Radial artery thrombosis is a rare complication of cannulation. There are no reported cases of acute thrombosis and severe acute neuropathy in the setting of cannula discontinuation. We report a case of acute radial nerve mono-neuropathy following thrombosis after radial arterial line removal. The thrombus was immediately evident on exam and diagnostic imaging after cannula discontinuation. The patient was consented and promptly taken to OR for immediate repair. Mild radial neuropathy persisted despite immediate repair. Immediate recognition of signs and symptoms is essential for diagnosis and management, especially in the high-risk population.
RESUMO
BACKGROUND: This study was designed to determine the clinical significance of preoperative thrombocytosis in patients with malignant peritoneal mesothelioma (MPM) undergoing operative cytoreduction (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). CRS and HIPEC have been associated with prolonged survival in patients with MPM and is the preferred treatment in select patients. However, patient selection criteria remain ill-defined for this operation that is also associated with significant morbidity and mortality. Preoperative thrombocytosis has been associated with poor outcomes in various malignancies but never studied in MPM. METHODS: Between January 2006 and December 2015, 100 patients with high-grade epithelioid MPM were evaluated and selected for CRS and HIPEC at our center (M: 53, F: 47; mean age: 54 years [range 17-81 years]). We analyzed various patient and treatment related factors potentially associated with overall survival (OS). RESULTS: The median actuarial overall survival was 32.8 months; the actuarial 1-, 3-, 5-year survivals were 70, 49, and 36%, respectively. On multivariate analysis, suboptimal resection (CCR > 1), high tumor burden (PCI > 20), and elevated preoperative platelet count (>367,000/mm3) were independently associated with shortened OS (P < 0.05). Median OS in patients with elevated versus normal platelet counts were 13 and 58 months, respectively (P < 0.001). Compared with patients with normal platelet counts, patients with elevated counts had significantly greater residual disease after operation (P = 0.008). CONCLUSIONS: Elevated preoperative platelet count is independently associated with poor outcome. Notably, thrombocytosis reflects aggressive tumor biology and should be considered a factor in patient selection for CRS and HIPEC.
