Balloon dilations

Abstract: PURPOSE: To perform a meta-analysis of long-term results of balloon dilation and stent implantation in the treatment of femoropopliteal arterial disease. MATERIALS AND METHODS: The English-language literature was searched for studies published between 1993 and 2000. Inclusion criteria for articles were presentation of long-term primary patency rates, standard errors (explicitly reported or derivable), and baseline characteristics of the study population. Two reviewers independently extracted data, and discrepancies were resolved by consensus. Primary patency rates were combined by using a technique that allows adjustment for differences across study populations. Analyses were adjusted for lesion type and clinical indication. RESULTS: Nineteen studies met the inclusion criteria, representing 923 balloon dilations and 473 stent implantations. Combined 3-year patency rates after balloon dilation were 61% (standard error, 2.2%) for stenoses and claudication, 48% (standard error, 3.3%) for occlusions and claud...

Abstract: Dysphagia is a common problem in the elderly population with an especially high prevalence in hospitalized and institutionalized patients. If inadequately addressed, dysphagia leads to significant morbidity and contributes to decreased quality of life. Dysphagia can be categorized as emanating from either an oropharyngeal or esophageal process. A disproportionate number of elderly patients suffer from oropharyngeal dysphagia with a multifactorial etiology. Historically, treatment options have been limited and included mostly supportive care with a focus on dietary modification, food avoidance, and swallow rehabilitation. Nascent technologies such as the functional luminal imaging probe (FLIP) and advances in esophageal manometry are improving our understanding of the pathophysiology of oropharyngeal dysphagia. Recent developments in the treatment of specific causes of oropharyngeal dysphagia, including endoscopic balloon dilations for upper esophageal sphincter (UES) dysfunction, show promise and are expected to enhance with further research. Esophageal dysphagia is also common in the elderly and more commonly due to an identifiable cause. The full breadth of treatment options is frequently unavailable to elderly patients due to comorbidities and overall functional status. However, the increasing availability of less invasive solutions to specific esophageal pathologies has augmented the number of treatment options available to this population, where an individualized approach to patient care is paramount. This review focuses on the evaluation and management of dysphagia in the elderly and delineates how standard and novel therapeutics are contributing to more nuanced and personalized management.

Abstract: Twenty-nine percutaneous balloon dilations of the axillary and subclavian veins were performed in 19 patients. Stenoses occurred in typical locations of anatomic narrowing or at sites of previous trauma. The initial success rate was 76%, with a 1-year patency rate of 35% and a 2-year patency rate of 6%. Angioplasty can be performed on an outpatient basis with a very low rate of significant complications and can be repeated numerous times to keep a vein patent for many years. This procedure is especially valuable in dialysis patients who have limited access sites.
