Comparative Study
Reintervention Rate after Open Surgery and Endovascular Repair for Nonruptured Abdominal Aortic Aneurysms.
We aim to determine the reintervention rate after open aortic aneurysm repair (OAR) or endovascular aneurysm repair (EVAR) according to compliance or noncompliance with the instructions for use (IFU) for commercial endovascular stent grafts. ⋯ In contrast to IFU EVAR group, the RFS and OS rates of non-IFU EVAR group were lower than in the OAR group during mid-term follow-up. Final endoleak was more frequent, and reintervention was more commonly performed in the non-IFU group than in the IFU group. Therefore, performing EVAR in non-IFU situations should be planned carefully.

Despite advances in endovascular surgery, lower extremity arterial bypass (LEB) remains the gold standard treatment for severe, symptomatic Peripheral Arterial Disease. With recent changes in health care, there has been an increasing emphasis on reducing the hospital length of stay (LOS). The purpose of this study was to identify the postoperative complications, which occur after discharge from hospital and to find risk factors for developing such complications. ⋯ Wound infection is the most common complication after LEB. Most of these complications occur after discharge from hospital. Patients with risk factors for developing wound infections should be followed and closely monitored after discharge from the hospital.

Exertional leg pain includes a broad range of conditions induced by different vascular, musculoskeletal, and neurological disorders. We report a case with isolated popliteal artery dissection as a cause of a transient acute lower limb ischemia. We report a patient with popliteal artery dissection which occurred during squatting exercise. ⋯ Isolated popliteal artery dissection in professional athletes is a rare entity, which can be manifested with exertional leg pain. Clinical findings can sometimes be similar to those of popliteal entrapment syndrome. Clinical suspicion and timely patient referral to a vascular specialist are crucial for optimal treatment of this limb-threatening condition.

Case Reports
Endovascular Repair of Ruptured Thoracoabdominal Aortic Aneurysm with an Off-the-shelf Endoprosthesis.
Thoracoabdominal aortic aneurysm type 3 (TAAA3) is a challenging disease to vascular surgeons. In these cases, the best treatment methodology is conventional surgery, which portends a mortality rate ranging from 8% to 25%. Endovascular treatment has been shown to be a good alternative, with encouraging results. In 2012, a new alternative for endovascular treatment of TAAA3 was presented: Cook T-Branch endoprosthesis (Cook Medical, Bloomington, Indiana). We present the first successful case of endovascular treatment of a ruptured TAAA3 with this stent. ⋯ Until now, the only endovascular alternative for ruptured aortic aneurysm was the parallel prosthesis technique. The development of an off-the-shelf T-Branch prosthesis (Cook Medical) has solved this problem in many cases, enabling immediate treatment of this type of aneurysm in approximately 83% of patients. The fact that the thoracic aorta would be excluded lead the patient to a high risk of spinal cord ischemia. We therefore decided to make a cerebrospinal fluid drainage. There is no consensus regarding the best devices to be used as branches. In this case, we chose to use the previously described covered stents, according to its flexibility and compatibility with the length of arteries. This is the first report of the use of a T-branch (Cook Medical) for treatment of a ruptured TAAA3. The development of an off-the-shelf endoprosthesis has many advantages: it is available for use in an emergency situation, and there is no time lapse for its preparation. The T-Branch stent graft is a valid option for the treatment of ruptured TAAA3.

Case Reports
Thrombolytic Therapy of Acute Massive Pulmonary Embolism Using Swan-Ganz Pulmonary Artery Catheter.
Acute massive pulmonary embolism (PE) is associated with high fatality, and catheter-directed thrombolytic therapy has been shown to be an efficacious treatment for this condition. We herein report a patient who developed acute massive PE but could not undergo the conventional catheter-directed thrombolytic therapy. A Swan-Ganz pulmonary artery catheter was placed at bedside to initiate immediate thrombolytic infusion, which resulted in dramatic clinical improvement. This report underscores a potential role of thrombolytic therapy via a transjugular pulmonary artery catheter in patients with acute massive PE who could not undergo the conventional catheter-based thrombolytic intervention.
