Standard salvage procedures for occuluded autologous arteriovenous fistula (AVF) in a hemodialysis patient are endovascular and/or surgical therapy. When endovascular therapy and thrombectomy prove unsuccessful, it is most likely that creating a new AVF or arteriovenous graft will be considered. However, if the occuluded venous part is short, we have adopted an operative technique for repair of AVF by removal of the occluded short venous part and venovenous end-to-end anastomosis. To our knowledge, the efficacy and clinical course of restoration of AVF by the technique have not been reported to date...

Situs inversus totalis (SIT) is a rare congenital anomaly characterized by complete inversion of the thoracic and abdominal organs. Many intra-abdominal and vessel anomalies have been reported in association with SIT. However, there have been no reports on the use of laparoscopic radical nephrectomy with thrombectomy for renal vein thrombus, which is considered as a safe and feasible procedure, in patients with SIT. We herein present the case of an 80-year-old man with SIT who was preoperatively diagnosed with a right renal tumor and renal vein tumor thrombus...

Renal vein thrombosis in a transplanted kidney is an uncommon but critical complication that can result in graft loss if management is delayed. A 31-year-old male with known atresia of the inferior vena cava who received a deceased donor renal transplant 7 years previously presented to hospital with severe graft site pain and a week of nausea, vomiting, and chills. Serum creatinine was markedly elevated from baseline. Sonographic examination revealed external iliac vein thrombosis with extension of the thrombus into the transplant renal vein...

OBJECTIVE: Acute stroke due to tandem cervical internal carotid artery (ICA) and intracranial large-vessel occlusion (ILVO) has a high rate of morbidity and mortality. The most appropriate treatment strategy for the extracranial culprit lesion remains unclear. In this study, we report our institutional outcomes with two approaches: emergent carotid endarterectomy (CEA) and carotid artery stenting (CAS). METHODS: Patients with tandem ICA-ILVO were identified in a prospective mechanical thrombectomy (MT) database between July 2012 and April 2016...

Chimney-and-periscope technique for thoraco-abdominal aneurysm repair is a valuable treatment option in selected patients. Acute renal artery occlusion is a serious complication after this technique. We report a case of acute right renal artery occlusion, consequent to a previous chimney-and-periscope technique that was treated urgently by mechanical aspiration thrombectomy.

PURPOSE OF REVIEW: Treatment recommendations for pregnancy associated ischemic stroke are scarce. This may be due to the fact that, in general, obstetricians tend not to make recommendations for stroke patients and neurologists are not commonly involved in the care of pregnant women. Herein, we review the multiple etiologies of ischemic stroke during pregnancy, considerations for diagnostic testing, and acute treatment and prevention options, including associated risks specific to the pregnant and puerperal state...

Venous thromboembolism, including deep vein thrombosis and pulmonary embolism, occur in up to 900,000 people per year in the United States. Current first-line therapy consists of systemic anticoagulation with a goal to prevent additional thrombus formation. Treatment with anticoagulation alone provides less than satisfactory results with some studies showing propagation of thrombus in almost 40% of cases. Current first-line therapy does not include active removal of thrombus and does little to alleviate acute symptoms and the damaging inflammatory response that may result in postthrombotic syndrome...

OBJECTIVE: To evaluate the effectiveness of micro-clamping stent-retriever thrombectomy (MSRT) in acute ischemic stroke patients with intracranial large vessel embolism (ILVE), and compare the same with conventional stent-retriever thrombectomy (CSRT). MATERIALS AND METHODS: We retrospectively evaluated a total of 108 ILVE patients treated by MSRT (n=52) and CSRT (n=56) from the two participating institutions between January 2016 and November 2017. The rates of successful (mTICI 2b or 3) and complete reperfusion (mTICI 3), time from guide catheter placement to reperfusion, rates of first-pass success, and the number of passes for reperfusion were compared between the MSRT and CSRT groups...

We evaluated the composition of individual clots retrieved during intra-arterial thrombectomy in relation to recanalization success, stroke subtype, and the presence of clot signs on initial brain images. We analyzed clot and interventional data from 145 retrieval trials performed for 37 patients (69.5±14.0 years, 20 men, large artery atherosclerosis, n = 7; cardioembolism, n = 22; undetermined etiology, n = 8) who had undergone intra-arterial thrombectomy. Rates of clot retrieval and successful recanalization (Arterial Occlusive Lesion score of 2-3) for separate retrieval trials were evaluated...

PURPOSE OF REVIEW: Recent advances in endovascular thrombectomy have made acute ischemic stroke due to a large vessel occlusion more treatable than ever. Rapid access to treatment remains paramount and multiple large vessel occlusion prediction scales have been created to enhance prehospital identification and triage of these patients. This review summarizes the current state of large vessel occlusion prediction scales, proposes a set of ideal scale features, and discusses the future of these scales and prehospital neurological emergency response systems...

Formation of tumor thrombus is an occasional manifestation of renal cell carcinoma (RCC). Intravascular invasion of the renal vein and thereafter the inferior vena cava (IVC) might in very rare cases extend into the cardiac chambers. The subtle course and symptoms of such cases alongside with the engagement of vital anatomical structures marks them as a diagnostic and therapeutic challenge. Aggressive surgical intervention has proven to be critical for survival rates in such cases; however total synchronous resection remains a challenge for the surgical team and a debate for the medical community...

Despite extensive research, treatments for clinical stroke are still limited only to the administration of tissue plasminogen activator and the recent introduction of mechanical thrombectomy, which can be used in only a limited proportion of patients due to time constraints. A plethora of inflammatory events occur during stroke, arising in part due to the body's immune response to brain injury. Neuroinflammation contributes significantly to neuronal cell death and the development of functional impairment and death in stroke patients...

Mechanical thrombectomy (MT) is the gold standard treatment for large vessel occlusion (LVO) stroke of the anterior circulation. Whether MT can also be effectively and safely performed in early recurrent LVO is largely unclear. We present the case of a middle-aged patient who was successfully treated by MT for right proximal middle cerebral artery (MCA) occlusion with excellent outcome. One day after discharge (9 days after the first MT), the patient was readmitted with wake-up stroke. MRI again revealed right proximal MCA occlusion with severe diffusion-perfusion mismatch...

BACKGROUND AND PURPOSE: The DAWN and DEFUSE-3 trials demonstrated the benefit of endovascular thrombectomy (ET) in late-presenting acute ischemic strokes due to anterior circulation large vessel occlusion (ACLVO). Strict criteria were employed for patient selection. We sought to evaluate the characteristics and outcomes of patients treated outside these trials. METHODS: A retrospective review of acute ischemic stroke admissions to a single comprehensive stroke center was performed during the DAWN trial enrollment period (November 2014 to February 2017) to identify all patients presenting in the 6-24 hour time window...

Acute ischemic stroke is a common cause of morbidity and mortality worldwide. Thrombolysis with recombinant tissue plasminogen activator and endovascular thrombectomy are the main revascularization therapies for acute ischemic stroke. However, ischemia-reperfusion injury after revascularization therapy can result in worsening outcomes. Among all possible pathological mechanisms of ischemia-reperfusion injury, free radical damage (mainly oxidative/nitrosative stress injury) has been found to play a key role in the process...

Neurological complications of infective endocarditis are frequent, especially ischaemic strokes. As intravenous thrombolysis in infective endocarditis-related ischaemic stroke has a controversial benefit/risk ratio, alternative treatment regimens have to be considered. We present the case of a young patient with septic embolism of the middle cerebral artery who was successfully treated with mechanical thrombectomy, and give a short review of the existing literature.
