Introduction The objective of this study was to evaluate the efficacy of ultrasound-accelerated catheter-directed thrombolytic therapy in patients with submassive pulmonary embolism. Methods Clinical records of 46 patients with submassive pulmonary embolism who underwent ultrasound-accelerated catheter-directed pulmonary thrombolysis using tissue plasminogen activator, from 2007 to 2017, were analyzed. All patients experienced clinical symptoms with computed tomography evidence of pulmonary thrombus burden. ⋯ The right ventricular function remained improved at 6 months and 12 months of follow-up, as right ventricle-to-left ventricle ratio were 0.92 ± 0.14 ( p < 0.01) and 0.91 ± 0.15 ( p < 0.01), respectively. Conclusion Ultrasound-accelerated catheter-directed thrombolysis is a safe and efficacious treatment for submassive pulmonary embolism. It reduces pulmonary hypertension and improves right ventricular function in patients with submassive pulmonary embolism.

Objective Postoperative pain following lower extremity revascularization procedures is traditionally controlled with narcotic administration. However, this may not adequately control the pain and puts the patient at risk for complications from opiate use. Here we report an alternative strategy for pain management using a continuous catheter-infused local anesthetic into the operative limb. ⋯ Readmission rates were 23% (continuous catheter-infused local anesthetic) and 21% (controls; P=0.84). Conclusion Postoperative continuous catheter-infused local anesthetic reduces pain scores and pain medication use compared to standard opiate therapy in these patients, without increasing wound complication or readmission rates. Continuous catheter-infused local anesthetic appeared to have no effect on the incidence of pulmonary complications, mobilization, or fever.

Objective With the implementation of the K-DOQI guidelines, more patients are in need of long-term dialysis catheters until maturation of the arteriovenous fistula. However, on occasion, when placing a tunneled cuffed catheter for hemodialysis, we have encountered difficulty with passing the guidewire in spite of demonstration of a patent cervical portion of the internal jugular vein on duplex. Herein, we review our experience with intraoperative venoplasty for placement of Tesio™ catheters (Medcomp Harleysville, PA). ⋯ In the additional one case, the catheter was not able to be placed despite angioplasty. Seven lesions that underwent balloon angioplasty were in the innominate vein, 11 were in the proximal internal jugular vein, and two were in the superior vena cava. Conclusion Venous balloon angioplasty can be used to maintain options for the site of access for tunneled cuffed catheters and may be necessary to assist with placement of long term cuffed dialysis catheters.
