Cannulation of the radial artery is frequently performed for invasive hemodynamic monitoring. Complications arising from indwelling catheters have been described in small case series; however, their surgical management is not well described. Understanding the presentation and management of such complications is imperative to offer optimal treatment, particularly because the radial artery is increasingly accessed for percutaneous coronary interventions. ⋯ Complications of radial artery cannulation requiring surgical intervention can represent infectious and ischemic sequelae and have the potential to result in major morbidity, including digital or hand amputation and sepsis, or death. Although surgical treatment is successful and often required in these patients to treat severe hand ischemia, hemorrhage, or vascular infection, these complications tend to occur in critically ill hospitalized patients with an extremely high mortality. This must be taken into consideration when planning surgical intervention in this patient cohort. Finally, radial arterial cannulation sites should not be overlooked when searching for occult septic sources in critically ill patients.

Vascular trauma from large-dog bites present with a combination of crush and lacerating injuries to the vessel, as well as significant adjacent soft tissue injury and a high potential for wound complications. This retrospective case series evaluates our 15 years of experience in managing this uncommonly seen injury into suggested treatment recommendations. ⋯ Dog bite vascular injuries are an uncommon occurrence, where extremity pulse abnormalities are the most common presentation. These injuries are also associated with significant adjacent soft tissue trauma, which warrants aggressive debridement and perioperative antibiotic therapy. Despite vigilant management, nearly one-fifth of our patients sustained wound infections. All infections were successfully managed with broad-spectrum antibiotics, and all limbs were preserved 1-year postoperatively.
