Risk factors and outcomes regarding the acute kidney injury after AngioJet thrombectomy for acute lower-extremity deep vein thrombosis.

OBJECTIVE: To investigate the risk factors and outcomes regarding acute kidney injury (AKI) after AngioJet thrombectomy for acute lower-extremity deep vein thrombosis (DVT). METHODS: Patients were divided into AKI and non-AKI groups according to whether AKI occurred postoperatively. The demographic data, pre-operative and post-operative laboratory data and surgical differences were compared between the two groups. Logistic regression and Wilcoxon signed-rank test were used to identify the AKI risk factors and outcomes, respectively. RESULTS: Among the 341 patients who met the inclusion criteria, 45 developed AKI (AKI group) and 296 had normal renal function (non-AKI group) post-surgery. There were significant differences between the two groups in the course (t = 10.885, P = 0.000); preoperative history of a major surgery within 3 months (3M-MS) (odds ratio [OR] = 5.492, P = 0.001); duration of aspiration thrombectomy (Z = -8.803, P = 0.000); volumes of aspiration (Z = -8.215, P = 0.000); contrast volume (Z = -3.204, P = 0.001) and pulmonary thrombectomy (OR = 18.200, P = 0.002); and preoperative complications of hypertension (OR = 4.637, P = 0.002), diabetes (OR = 18.088, P = 0.000), or pulmonary embolism (OR = 0.085, P = 0.011). Wilcoxon signed-rank test showed that the renal function of every patient in the AKI group returned to normal 3 months after the surgery. CONCLUSIONS: The course, preoperative complications of diabetes or hypertension, 3M-MS, contrast volume, duration and volume of aspiration thrombectomy, and pulmonary thrombectomy are risk factors for post-AngioJet-thrombectomy AKI, which is temporary.

Covered Stent-Assisted Open Surgery in the Treatment of an Extracranial Carotid Artery Pseudoaneurysm.

Extracranial carotid artery pseudoaneurysms (ECAPs) are rare vascular lesions that, if untreated, can lead to severe neurologic deficits and significant mortality. Although conservative therapy, surgical ligation or reconstruction, and endovascular techniques can be curative, the literature demonstrates that the best therapy remains controversial and consensus is lacking. We report a case of a 53-year-old patient who developed a giant ECAP on the left side of her neck, which had been presented for 10 years and was successfully treated by covered stent-assisted open surgery. During the 6 months of follow-up, computed tomography angiography confirmed complete occlusion of the ECAP and patency of the carotid artery. In addition to this report, a brief review of the literature is presented.
