The authors report the case of a 34-year-old male, who underwent a fluorine-18 fluoro deoxyglucose (¹⁸F-FDG) positron emission tomography/computed tomography (PET/CT) scan 7 years after trauma for the evaluation of multifocal masses in the right iliac and right inguinal areas. CT findings showed multifocal low density masses and ¹⁸F-FDG PET revealed slightly increased uptake (maximum standardized uptake value [SUVmax] 3.1). These findings did not exclude the possibility of a benign or malignant lesion. To achieve differential diagnosis, partial surgical excision was performed and a pathologic examination subsequently revealed lymphangioma. Here, the authors describe the ¹⁸F-FDG PET/CT findings of a rare case of lymphangioma resulting from trauma.

Anatomical variations of carotid arteries may be related to their development (agenesis, aplasia, hypoplasia) or course (coiling, kinking, tortuosity). Partial or total aberrancies in carotid vessel anatomy rarely occur. We describe the case of a 95-year-old woman presented with sudden onset of confusion and disorientation together with upper limb clonus. Computed tomography (CT)-scan revealed a left frontal brain injury with a not conclusive carotid doppler ultrasound. CT angiography reported a bovine aortic arch with bilateral retroesophageal course of both common carotid arteries and left severe (>70%) internal carotid artery stenosis. The knowledge of anatomical variations of the course of carotid arteries is relevant for possible surgical or endovascular repair or in case of otolaryngology or intubation procedures.

This is a case report that suggests the possible association between multiple splanchnic arterial aneurysms and long-distance running. The clinical features of one patient admitted at Chungbuk National University Hospital for treatment of multiple splanchnic arterial aneurysms were reviewed. A 54-year-old man had a recurrent, intermittent and epigastric pain for 2 months. There was no abnormality in gastroscopy and colonoscopy. An abdominal computed tomography angiography documented calcified superior mesenteric artery (SMA) and splenic artery aneurysms. The patient had a history of recreational long-distance running for over 10 years. His average running time per week was more than 10 hours. There was no evidence of systemic arteritis, connective tissue disorder or infectious process that may have caused the aneurysms. He did not take any drugs. The SMA aneurysm was opened, and the aneurysmal segment of SMA was replaced with a vein graft. The splenic aneurysm was observed. The patient recovered without any sequelae.

In this study, we describe our diagnosis and treatment of two patients who presented with femoral vessel compression caused by a cystic lesion in the groin. One case was diagnosed as adventitial cystic disease (ACD) of the common femoral artery resulting in leg claudication and the other was diagnosed as a ganglion cyst (GC) causing femoral vein compression and unilateral leg swelling. The operative findings differed between these two cases with respect to the dissection of the cyst and femoral vessel, but the postoperative histological examination results were similar. The pathogenesis of ACD and GC is not fully understood, and further investigation is needed to delineate the exact pathology of these uncommon conditions.

Venous aneurysms of the jugular vein are one of the rare causes of neck swelling, and primary venous aneurysms of the external jugular vein are extremely rare. A 46-year-old woman presented with a painless and suddenly growing mass in the left neck. A computed tomography angiography revealed a fusiform venous aneurysm of the external jugular vein containing intraluminal thrombus. We performed resection of the aneurysm and ligation of the external jugular vein. Removal of the aneurysm of the neck vein was necessary because venous aneurysms with thrombosis may lead to serious thrombotic complications such as pulmonary embolism.

Phlegmasia cerulea dolens (PCD) is a medical emergency that can lead to venous gangrene of the lower extremity. Early diagnosis and prompt treatment is crucial for limb salvage. There are two treatment options (endovascular or surgical). In the endovascular era, catheter-directed thrombolysis is the treatment of choice to achieve venous outflow. However, surgical thrombectomy is indicated in certain cases. The authors report successful surgical thrombectomy in a 75-year-old man with PCD and review the treatment of PCD.

Spontaneous renal artery dissection (SRAD) is a rare disease entity. The diagnosis is usually delayed because clinical presentation is non-specific. We report three cases of symptomatic SRAD complicated by renal infarction which occurred in previously healthy middle-aged male patients. They visited the hospital due to acute abdominal or flank pain. They had no specific underlying disease or trauma history. The laboratory tests and physical examination were normal. They were not suspected of having SRAD initially, but computed tomography (CT) revealed dissection of the renal artery with distal hypoperfusion leading to renal infarction. They were treated conservatively with anticoagulation and/or antiplatelets for 6 months. They had a 6-month regular follow-up with CT, where resolution was confirmed in one patient and all patients remained asymptomatic. These cases emphasize the importance of clinical suspicion of SRAD in previously healthy patients who complain of abdominal pain without specific findings on initial investigation.

We report an endovascular aneurysm repair in a patient with isolated bilateral common iliac artery aneurysms, a prominent inferior mesentery artery (IMA), and bilateral proximal internal iliac artery (IIA) aneurysms using covered self-expanding stents to preserve the IMA and bilateral internal iliac arteries. A follow-up computed tomography angiography was obtained at 1 month. Pelvic circulation was well preserved without bowel ischemia. IMA and bilateral IIA preservation with covered self-expanding stents during endovascular aneurysm repair is a safe and effective method.

Hypercoagulable states have been associated with aortic thrombosis. Antiphospholipid syndrome (APS) is one of the commonest types of acquired thrombophilia. We report the case of successful anticoagulation management in an APS patient with mobile thrombi within the aorta. A 58-year-old male patient presented to the emergency department (ED) with right-sided hemiparesis. His first symptoms were noted approximately 12–16 hours before presentation to the ED. Magnetic resonance imaging of the brain showed acute embolic infarction of the left frontal and parietotemporal lobes. Transesophageal echocardiography (TEE) and computed tomography angiography (CTA) demonstrated mobile thrombi attached to the wall of the ascending aorta and aortic arch. The patient was diagnosed with APS based on positivity of anti-beta-2 glycoprotein 1 antibodies, and was initiated on anticoagulation therapy. Repeated TEE and CTA revealed complete resolution of the thrombi after 12 days of treatment; the patient was discharged well.

PURPOSE: The lower extremity has received its fair share of attention as a vascular access site in patients who have exhausted their upper arm vessels. However, experiences with lower extremity arteriovenous grafts (AVGs) have so far been disappointing because of high infection rates and severe limb ischemia. We report our experience with hemodialysis access from the lower extremity. MATERIALS AND METHODS: A retrospective review of 60 lower extremity AVGs created between January 2003 and December 2011 was performed. Age, sex, etiology of end-stage renal disease and complications were tabulated. Primary and secondary patency rates were determined. RESULTS: The average age of the study population was 56 years and 38 patients were female. Renal failure was associated with hypertension in 40 (66.7%) patients, diabetes in 28 (46.7%) patients and cardiovascular disease in 9 (15.0%) patients. The follow-up period was 8–108 months. Fifty-four patients had bilateral central vein stenosis. Seven (11.7%) patients had primary failure of their AVG. There was no operation-related death. Primary and secondary patency rates were: 66% and 90% at 1 year, 40% and 90% at 2 years, 27% and 87% at 3 years, and 18% and 87% at 5 years, respectively. There were 105 postoperative complications that developed in 67 patients. Postoperative complications were: thrombosis (30), proximal vein stenosis (56), infection (9), bleeding with hematoma (1), perigraft seroma (3), steal syndrome (2), and pseudoaneurysm (4). CONCLUSION: A lower extremity AVG seems to be a viable option in patients with unusable upper extremity veins.
