Comparative Study
Dialysis Access Surgery: Does Anesthesia Type Affect Maturation and Complication Rates?
Creation of an arteriovenous fistula (AVF) is the preferred method of establishing long-term dialysis access. There are multiple anesthetic techniques used for patients undergoing this surgery including general endotracheal intubation, laryngeal mask airway, regional anesthesia with nerve blocks, and monitored anesthesia care with local infiltration. It is unclear what effect the method of anesthesia has on AVF creation success rate. It is our objective to determine if anesthesia type affects success of these surgeries defined by complication and maturation rates. ⋯ Our study shows that despite anesthesia type, outcomes in terms of maturation and complication rate are not statistically different in AVF creation surgeries. The use of monitored anesthesia care with local anesthesia may improve operative efficiency in terms of time in the operating room and in the recovery unit and therefore may be the preferred method of anesthesia. This recommendation may also parallel the preference to avoid general anesthesia in a patient population with more medical comorbidities. It is our conclusion that dialysis access surgery should therefore be performed under local anesthesia with monitored anesthesia care.

Inferior vena cava (IVC) filter placement is not indicated for thrombolytic interventional treatment for deep vein thrombosis (DVT). We analyzed the efficacy and feasibility of retrievable IVC filter placement for the preventive management of embolic shedding during catheter-directed thrombectomy (CDT) for DVT of lower extremity. ⋯ Our study findings suggest that retrieval IVC filter placement during interventional treatments of DVT of lower extremity such as thrombectomy of vein thrombus with or without stent insertion at compressed deep vein is favorable and effective for protecting against PE or lethal complications. We recommend carefully that before the management of DVT thrombus of lower extremity, retrieval IVC filter placement should be considered for preventing morbidity related with the PE.

Pulmonary embolism (PE) associated with duplicated inferior vena cava (IVC) is rare, and there are no reports of this condition treated with catheter-directed thrombolysis. We present the case of a 54-year-old man who developed massive PE caused by thrombi in a duplicated IVC that detached during transcatheter angiography. ⋯ He was asymptomatic at discharge, with complete resolution of thrombosis and successful retrieval of the filter. The patient had an uneventful 9-month follow-up with no further complications.

Case Reports
Mycotic Abdominal Aortic Aneurysm Secondary to Septic Embolism of a Thoracic Aorta Graft Infection.
Mycotic aneurysms account for 1% of abdominal aortic aneurysms. There are very few cases published that describe the formation of mycotic aneurysms after septic embolism due to graft infection. We present the first case to our knowledge to be described in the literature of a mycotic aneurysm caused by septic embolism derived from a thoracic aorta graft infection, treated with conventional surgery leading to a successful outcome and evolution.

Review Case Reports
What We Can Learn from Cases of Synchronous Acute Mesenteric Obstruction and Nonocclusive Mesenteric Ischemia: How to Reduce the Acute Mesenteric Ischemia-Related Mortality Rate.
Although the survival rate of patients with ischemic heart disease has recently increased, it remains unknown why the mortality rate of acute mesenteric ischemia (AMI) remains high. Here, we report a possible method of improving the survival rate of patients with AMI obtained through 2 cases of simultaneous acute mesenteric obstruction (AMO) and nonocclusive mesenteric ischemia (NOMI). Case 1 was a 74-year-old woman with atrial fibrillation, hypertension, and dyslipidemia as underlying diseases who developed NOMI immediately after undergoing SMA thrombolysis. ⋯ However, no case of AMO plus NOMI has been reported until now. It is highly probable that concomitant NOMI is overlooked in cases of AMO. When managing AMO, NOMI should be considered as a complication, which may lower the patient's potential risk of developing NOMI and contribute to improved prognosis of both AMO and AMI.
