Tissue loss secondary to extrinsic compression of common iliac artery from uterine leiomyoma: a case report and review of the literature.

Background: Uterine leiomyomas are commonly reported to cause deep venous thrombosis and rarely arterial compression.

Case: A 48-year-old woman was transferred to our institution with acute right lower limb ischemia and tissue loss. She underwent urgent iliac thrombectomy and was subsequently found to have right common iliac artery compression by a large uterine leiomyoma.

Predictability of cerebral embolization from aortic arch manipulations during thoracic endovascular repair.

There is no sensitive tool to monitor embolic events and predict patients at a risk for strokes during thoracic endovascular aortic repair. We examined the relationship between the number of high intensity transient signals (HITS) by transcranial doppler ultrasound and the extent of atherosclerotic plaques in aortic arch. Thirteen patients were treated as a part of a single center United States Food and Drug Administration-approved investigational device exemption for various thoracic aortic pathologies.

Pre-operative regional block anesthesia enhances operative strategy for arteriovenous fistula creation.

Purpose: We aim to assess the effect of regional block anesthesia on vein diameter, type of AVF placement, and fistula size and flow volume.

Methods: 30 patients presenting for AV access procedures were followed prospectively. Vein diameters via venous ultrasound and planned location for AV access were documented.

Aortic remodeling, volumetric analysis, and clinical outcomes of endoluminal exclusion of acute complicated type B thoracic aortic dissections.

Objective: Structural changes within the aorta after thoracic endovascular aortic repair (TEVAR) for acute complicated type B thoracic aortic dissections (ABAD) remain unknown. This study reviewed and analyzed morphologic changes, volumetric data, and clinical outcomes of patients with ABAD.

Methods: Forty-one consecutive patients with ABAD, all with the volumetric analysis of aortic luminal changes and ≥1 year of follow-up, were treated as a part of a single-center U.

Computed tomographic angiography as the primary diagnostic modality in penetrating lower extremity vascular injuries: a level I trauma experience.

Background: Computed tomographic angiography (CTA) has been established as a valid modality for the assessment of extremity vascular injury. Over the last several years at our institution, CTA has evolved as the primary diagnostic modality for penetrating extremity injuries, largely replacing diagnostic angiography. The purpose of this study was to evaluate the outcomes with this imaging modality at a high-volume Level I trauma center.

The application of duplex surveillance after carotid intervention.

Carotid duplex ultrasound testing provides a safe and accurate method to detect and grade the severity of atherosclerotic internal carotid artery stenosis both before and following carotid intervention. Testing after surgical endarterectomy or stent angioplasty allows assessment of the technical success by excluding residual stenosis. The focus of duplex surveillance after carotid intervention is to identify recurrent stenosis, repair site occlusion, and progression of contralateral internal carotid artery disease.

Duplex ultrasound surveillance can be worthwhile after arterial intervention.

A surveillance program based on duplex ultrasound testing after peripheral arterial intervention can increase long-term patency by identifying and by repairing clinical significant lesions. Its successful application requires numerous conditions regarding pathobiology of arterial repair failure and its consequences, arterial testing expertise, and durability of secondary procedures used to repair duplex-detected lesions. The methodology of surveillance should be tailored to the type of arterial intervention.

Scrotal necrosis following endovascular abdominal aortic aneurysm repair.

Scrotal necrosis is an extremely rare complication following endovascular abdominal aortic aneurysm repair. Sloughing of scrotal skin and penile necrosis owing to therapeutic hypogastric artery occlusion for endoluminal aortoiliac aneurysm repair have been documented. We present herein one case of scrotal necrosis following endovascular abdominal aortic aneurysm repair.

Distal peripheral microembolism.

Distal peripheral microembolism is caused by embolization of atherosclerotic debris into small arteries and arterioles. The recent advances in endovascular technique have been met with a gradual increase in the incidence of iatrogenic atheroembolism. This review seeks to explore the nature of distal peripheral microembolism, pathophysiology, and the management options, with a focus on iatrogenic distal peripheral microembolism.

Renal arteriovenous aneurysm in a 4-year-old patient.

We report a case of a symptomatic renal arteriovenous aneurysm in a 4-year-old pediatric patient. We were able to diagnose the lesion by means of a Doppler renal sonogram with color duplex interrogation. The diagnosis was confirmed by digital subtraction angiography.
