We report a case of a 56-year-old male patient with a life-threatening left common femoral artery bleeding due to tumor erosion. The patient had a history of advanced high-grade pleomorphic leiomyosarcoma of the left groin with pulmonary metastasis. Clinical examination revealed a massive tumor bulking at the left groin with necrosis and phleb- and lymphedema. Given the circumstances, open surgery was not possible. Thus, it was decided to treat the patient with an endovascular procedure. The postprocedural course was uneventful, the patient received blood product and was hemodynamically stable...

Atherosclerotic renal artery stenosis is the leading cause of secondary hypertension; it can also cause progressive renal insufficiency and cardiovascular complications such as refractory heart failure and flash pulmonary edema. Medical therapy including risk factor modification, renin-angiotensin-aldosterone system antagonists, lipid lowering agents, and antiplatelet therapy is the first line of treatment in all patients. Patients with uncontrolled renovascular hypertension despite optimal medical therapy, ischemic nephropathy, and cardiac destabilization syndromes who have severe renal artery stenosis are likely to benefit from renal artery revascularization...

Roughly 10% of lung transplant recipients experience airway complications. Although the incidence has decreased dramatically since the first lung transplants were performed in the 1960s, airway complications have continued to adversely affect outcomes. Bronchoscopic interventions such as balloon dilation, airway stenting, and endobronchial electrocautery play an important role in ameliorating the morbidity and mortality associated with these complications. This review describes the array of bronchoscopic interventions used to treat airway complications after lung transplant and how these techniques can be used in nontransplant settings as well...

REVIEW
Resmi Ann Charalel, Suresh Vedantham
The presence of cancer increases the risk of deep vein thrombosis (DVT), DVT recurrence, and treatment-related bleeding, and therefore offers distinctive clinical considerations when planning treatment. Anticoagulation with a low-molecular-weight heparin is the preferred initial and long-term therapy in cancer patients. Inferior vena cava filters may be used judiciously for patients with cancer-related DVT who have contraindications to anticoagulation or who exhibit breakthrough pulmonary embolism (PE) despite anticoagulation, but should be removed when the PE risk is felt to subside...

OBJECTIVE: Airway obstruction in children may be caused by conditions such as vascular compression and congenital tracheobronchomalacia. Obstructive pulmonary vascular disease may be a detrimental sequel for patients with congenital heart disease. We evaluate our own original external stenting technique as a treatment option for these patients. METHODS: Ninety-eight patients underwent external stenting (1997-2015). Cardiovascular anomalies were noted in 82 (83.7%)...

A proper interpretation of the forces developed during stent crimping and deployment is of paramount importance for a better understanding of the requirements for successful heart valve replacement. The present study combines experimental and computational methods to assess the performance of a nitinol stent for tissue-engineered heart valve implantation. To validate the stent model, the mechanical response to parallel plate compression and radial crimping was evaluated experimentally. Finite element simulations showed good agreement with the experimental findings...

We describe a 54-year-old male with history of type II DM, hypertension and dyslipidemia during admission for bronchopneumonia discovered to have coarctation of the aorta and a persistent left superior vena cava (PLSVC) draining into the left atrium through the left superior pulmonary vein. The latter was thought to contribute to a transient ischemic attack and an episode of chest pain resulting in ST-segment elevation in the inferior leads. He was treated with coarctation stenting and percutaneous exclusion of the PLSVC with a vascular plug...
