Objectives: Radial artery access is widely utilized in coronary angiography with reported lower rates of vascular complications and better patient comfort. There is limited data in the literature regarding radial access in peripheral endovascular procedures. We hypothesize that radial access is safe and feasible for peripheral endovascular procedures. Methods: A retrospective chart review was performed for all patients who underwent angiography using radial artery access between August 2013 and December 2017. Patient demographics and perioperative data were recorded and analyzed. Patient Selection: The operating surgeon screened patients presenting for elective angiography for possible radial artery access. Ultrasound guidance was used in all cases. Upon cannulation, the sheath was infused with an antispasmodic cocktail, and the patients were systemically anticoagulated. Results: Forty-seven out of 52 patients successfully completed their procedure (90% success rate). The patients were mostly female (60%), elderly (mean age of 71 years), and had several comorbidities. Preoperative diagnoses were variable. Procedures were both diagnostic (58%) and interventional (42%) with maximum sheath size used being 7F and median fluoroscopy time of 7.5 minutes. Only 2 patients experienced perioperative complications, and both of these were minor hematomas that resolved with manual pressure. Conclusions: Transradial arterial access for peripheral vascular angiography and interventions is safe and feasible. With low complication rates and increased patient comfort, transradial access serves as an excellent alternative to transfemoral access for a variety of endovascular procedures.

Pneumothorax can be spontaneous or secondary to a pre-existing disorder or trauma. Pneumothorax associated with pneumoperitoneum without thoraco-abdominal communication is a rare event poorly described in the literature. We report the case of a 73-year-old patient undergoing abdominal debulking surgery for advanced stage ovarian cancer complicated by a pneumoperitoneum and a right-sided pneumothorax without hernia or evidence of diaphragmatic trauma. Several physio-pathological hypotheses have been suggested, including a potential COVID-19 infection without clear etiology. Our case report emphasizes the possible association of pneumothorax with pneumoperitoneum related to a colon perforation without visible diaphragmatic or mediastinal defects.
