There is limited data regarding hyperbaric oxygen's effectiveness in the treatment of nonhealing arterial insufficiency ulcers. This study was designed to analyze healing rates and amputation rates in patients who underwent adjunctive hyperbaric oxygen for a nonhealing arterial insufficiency ulcer. A retrospective chart review was completed on patients who underwent hyperbaric oxygen for arterial insufficiency ulcers that failed to heal despite standard treatment. Information collected included complete ulcer healing, amputation, and patient characteristics. There were 82 patients identified. A majority did not have diabetes (84.1%). The overall rate of healing was 43.9%. The overall major amputation rate was 17.1%. The amputation rate among those who healed was 0% compared to 42.4% among those not healed (p < 0.0001). Dialysis was predictive of major amputation (p = 0.03). Our findings suggest hyperbaric oxygen can play a role in management of arterial insufficiency ulcers that have failed standard treatment. The overwhelming majority of these patients did not have diabetes, which allows this study to be translated to patients with a primary arterial insufficiency ulcer. These results support the use of hyperbaric oxygen for select nonhealing arterial insufficiency ulcers that have failed standard therapy and the need for a prospective pilot study.

Long-Term Outcomes of Endovascular Aortic Repair with Parallel Chimney or Periscope Stent Grafts for Ruptured Complex Abdominal Aortic Aneurysms.

: The parallel stent graft endovascular aortic repair (PGEVAR) technique is an off-the-shelf option used for elective complex abdominal aortic aneurysm repair with acceptable outcome results, as reported so far. The PGEVAR technique, using chimney or periscope parallel grafts, can also be used for patients with ruptured complex abdominal aortic aneurysms. However, only few data about the mid- to long-term outcomes are available.

Mediastinal mass syndrome represents a major threat to respiratory and cardiovascular integrity, with difficult evidence-based risk stratification for interdisciplinary management. We conducted a narrative review concerning risk stratification and difficult airway management of patients presenting with a large mediastinal mass. This is supplemented by a case report illustrating our individual approach for a patient presenting with a subtotal tracheal stenosis due to a large cyst of the thyroid gland.

Background: Left ventricular unloading is needed in patients on extracorporeal life support (ECLS) with severely impaired left ventricular contractility to avoid stasis and pulmonary congestion, and to promote LV recovery. The presence of thrombi in the LV precludes the use of conventional active unloading methods such as transaortic microaxial pumps or apical LV vents. We describe placement of a vent cannula via the left atrial appendage (LAA) as a useful bailout option.

Foley balloons have been used to secure emergency hemostasis for cardiac or vascular injuries since the 1960s. However, using a single large balloon may have drawbacks, such as insufficient hemostasis and blood flow impairment. We have encountered 3 major intraoperative laceration cases since 2011.

Mechanical valve leaflets have the potential to detach and migrate to unintended locations, leading to life- and limb-threatening situations. We report a unique case of a dislodged mechanical aortic valve leaflet in the right iliac artery bifurcation after a redo mitral valve replacement. This was promptly recognized by input from a multidisciplinary team, allowing immediate correction of the aortic valve insufficiency followed by staged retrieval of the dislodged leaflet to avoid vascular complications.
