Smoking Significantly Impacts Persistence Rates in Embolized Pulmonary Arteriovenous Malformations in Patients with Hereditary Hemorrhagic Telangiectasia.

Background Embolization is the standard of care for treatment of pulmonary arteriovenous malformations (PAVMs). Persistence of PAVMs after embolization occurs for undefined reasons but may include inflammation related to smoking in dysregulated angiogenesis. Purpose To determine whether patients with hereditary hemorrhagic telangiectasia (HHT) who smoke tobacco are more prone to PAVM persistence after embolization.

Is Long-Term Anticoagulation Required after Stent Placement for Benign Superior Vena Cava Syndrome?

Purpose: To identify whether symptom relief and stent patency vary with use of long-term anticoagulation after stent placement for benign superior vena cava (SVC) syndrome.

Materials And Methods: Patients with benign SVC syndrome treated with stent placement between January 1999 and July 2017 were retrospectively identified (n = 58). Average age was 49 years (range, 24-80 y); 34 (58%) were women, and 24 (42%) were men.

Comparison of Bleeding Complications between Transplenic versus Transhepatic Access of the Portal Venous System.

Purpose: To evaluate the incidence of bleeding complications between transplenic (TS) and transhepatic (TH) access in portal venous interventions.

Materials And Methods: Retrospective review of patients who underwent TS or TH access for portal venous system interventions from January 2000 to August 2017. Only procedures with clinical and laboratory follow-up were included (n = 148).

Comparison of Covered Versus Uncovered Stents for Benign Superior Vena Cava (SVC) Obstruction.

Purpose: To identify whether long-term symptom relief and stent patency vary with the use of covered versus uncovered stents for the treatment of benign SVC obstruction.

Methods And Materials: We retrospectively identified all patients with benign SVC syndrome treated to stent placement between January 2003 and December 2015 (n = 59). Only cases with both clinical and imaging follow-up were included (n = 47).

Outcomes After Cryoablation Versus Partial Nephrectomy for Sporadic Renal Tumors in a Solitary Kidney: A Propensity Score Analysis.

Background: While partial nephrectomy (PN) is considered the standard approach for a tumor in a solitary kidney, percutaneous cryoablation (PCA) is emerging as an alternative nephron-sparing option.

Objective: To compare outcomes between PCA and PN for tumors in a solitary kidney.

Design, Setting, And Participants: Patients who underwent PCA or PN between 2005 and 2015 for a single primary renal tumor in a solitary kidney were identified using Mayo Clinic Registries.

Comprehensive assessment of renal tumour complexity in a large percutaneous cryoablation cohort.

Objective: To evaluate the association between renal tumour complexity and outcomes in a large cohort of patients undergoing percutaneous cryoablation (PCA).

Patients And Methods: Patients with renal tumours treated with PCA were identified using our prospectively maintained ablation registry (2003-2015). Salvage procedures and inherited tumour syndromes were excluded.

Stereotactic body radiation therapy of liver tumors: post-treatment appearances and evaluation of treatment response: a pictorial review.

Stereotactic body radiation therapy (SBRT) is a noninvasive treatment technique for selected patients with primary liver tumors and liver-confined oligometastatic disease. Recently, SBRT has emerged as an alternative treatment option in non-surgical candidates and in whom percutaneous treatment methods are not possible or contraindicated. The experience with SBRT continues to grow.
