BACKGROUND: While gun-related penetrating traumatic brain injuries make up the majority of cranial missile injuries, low-velocity penetrating injuries present significant clinical difficulties that cannot necessarily be identically managed. Bow hunting is an increasingly popular pastime, and a crossbow allows a unique mechanism to cause a self-inflicted cranial injury with a large, low-velocity projectile. Historically, arrow removal is described in an operating room setting, which provides limited knowledge of the location of vascular injury in the setting of post-removal hemorrhage, and may represent an inefficient use of operating room availability...

Peripheral vascular malformations (PVMs) represent a wide spectrum of vascular abnormalities occurring due to anomalous connections between arteries, veins, capillaries, and lymphatic channels at the microscopic level, in different combinations. They are rare and challenging to treat. Different operators may have different approaches based on their experience and expertise. Sclerotherapy either alone or in combination with embolization has been used as an independent method for the treatment of PVMs. Purpose The aim of this study is to assess the safety and efficacy of sclerotherapy and embolization, with or without surgery, for the treatment of peripheral vascular malformations, based on our approach...

PURPOSE: Autogenous arteriovenous fistulas are the preferred access for hemodialysis. Yet when created, fistulas often fail to mature, requiring surgical or radiologic interventions before their use. This pilot study measures the vascular wall elasticity and flow gradient using an open-source ultrasound software program designed to aid in assessing fistula maturation. METHODS: A total of seven end-stage renal disease patients were enrolled for our study after providing informed consent...

Congenital portosystemic shunts (CPSS) are rare vascular malformations that create an abnormal connection between portal and systemic veins resulting in complete or partial diversion of the portal flow away from the liver to the systemic venous system. Different anatomic types exist and several classifications have been proposed. They can be associated with other malformations especially cardiac and heterotaxia. The main complications include hepatic encephalopathy, liver tumors, portopulmonary hypertension, and pulmonary arteriovenous shunts...

Abdominal aortic aneurysms (AAAs) are a relatively common vascular problem that can be treated with either open, surgical repair or endovascular aortic aneurysm repair (EVAR). Both approaches to AAA repair require dedicated preoperative imaging to minimize adverse outcomes. After EVAR, cross-sectional imaging has an integral role in confirming the successful treatment of the AAA and early detection of complications related to EVAR. CT angiography is the primary imaging modality for both preoperative planning and follow-up after repair...

To prevent and decrease procedural complications, it is important to identify variants of hepatic vascular anatomy before interventional radiologic procedures, surgery, and liver transplantation. Knowledge of the vascular variants helps in selecting patients and in exploring alternative management options. Non-invasive detailed demonstration of the hepatic vascular anatomy is possible with advanced multi-detector computed tomography (CT) and magnetic resonance (MR) imaging. The objective of this review is to provide a brief overview of clinically relevant hepatic vascular anatomy and important variants...

Spinal epidural abscess (SEA) is an extremely rare and disastrous musculoskeletal complication of spondylodiscitis and sacroilitis secondary to brucellosis infection. Few case reports and retrospective studies have been published reporting patients with epidural abscesses mainly lumbar, and thoracic while cervical abscess are rare. Management of spinal epidural abscess due to Brucella species is not standard and remains controversial. To the best of our knowledge this is the first case of brucellar cervical epidural abscess reported in Saudi Arabia...

The modern application of interventional radiology techniques is revolutionizing the treatment of the vascular malformations of the head and neck. In fact, the morbidity related with the surgical extirpation of the malformation might be drastically reduced with the use of an endovascular approach. The present report describes the case of a 11 years old male affected by a large intraosseous arteriovenous malformation of the mandible. The coil embolization of the main drainage vein caused the spontaneous regression of the lesion and avoided a mutilating surgery and severe psychological sequels...

Kidney cancer is the 9th most common cancer in men and the 14th most common in women worldwide. Renal cell carcinoma (RCC) constitutes 90% of all malignancies of the kidney. RCC, is known to be highly vascular and relatively radioresistant. Bone metastases are one of the most common metastatic sites and occur in around 30% of RCCs. They significantly impact the quality of life of patients causing pain and pathological fractures. Spinal metastases represent a particular case with regard to symptoms and treatment...

In recent years, many diagnostic algorithms have been devised to reduce the rate of negative explorations associated with indiscriminate surgical management of penetrating neck injuries. In hemodynamically stable patients, the need for surgical intervention is usually determined by integrating both clinical signs and radiological findings; if such investigations remain unremarkable, recommended treatment consists in close observation and sequential physical examinations. We report on a 29-year-old male who was admitted to a Swiss tertiary care hospital after sustaining a penetrating injury to his left neck following a knife attack...

Background: Congenital duplication of lower extremity, either complete or incomplete is extremely rare. Only 26 cases had been reported till 2010, of which only 5 cases had feature of complete duplication. Theories have been proposed that the cause of this abnormality includes maternal factors like diabetes and usage of teratogenic drugs. Duplication of lower extremity may mimic that of vestigial parasitic twin; phenotypically, it appears as an individual with extra appendage or limbs...

INTRODUCTION: Simultaneous kidney and pancreas transplant is the preferred treatment option for end-stage renal disease due to type 1 diabetic nephropathy. Vascular complications are detrimental to graft survival and can lead to graft loss in the early postoperative phase of transplantation. Generally, duplex Doppler ultrasound is used for vascular patency monitoring and pancreatectomy followed by re-transplantation is required in the majority of cases. Recently, pancreatic graft salvage with non-operative management, including medical anticoagulation and endovascular thrombectomy, in the early postoperative period has been described with success...

BACKGROUND AND PURPOSE: The thyrocervical trunk (TCT) is the second ascending branch of the subclavian artery. It is considered a 'border territory' between interventional vascular radiology and interventional neuroradiology because it gives rise to branches both cervical and to the upper limbs. We describe the TCT branches anatomy, the most frequent variants, and expose eight endovascular procedures performed through the thyrocervical trunk. METHODS: A retrospective review of all the interventional radiology procedures carried out through the TCT in our tertiary care center from August 2014 to January 2017 is presented...

Background: Retrieval of inferior vena cava filters (IVCFs) is important to decrease the long-term risk of complications associated with indwelling devices. Our hospital experienced low retrieval rates and implemented a low-cost intervention and evaluation for quality improvement. The working hypothesis was that a simple, mailed letter intervention could increase retrieval rates by increasing patient and primary care provider knowledge of the need for retrieval. Methods: For all prospective patients who received a retrievable IVCF during the intervention period from January 1, 2014 to February 29, 2016, patients and their primary care providers were mailed letters encouraging contact with the clinic for evaluation of eligibility for retrieval...
