Prosthetic carotid bypass graft for in-stent restenosis performed for post-endarterectomy recurrent stenosis: technical details

Aim. Carotid artery stenting (CAS) is the treatment of choice for recurrent stenosis after carotid endarterectomy (CEA). However a significative incidence of in-stent restenosis could be occurred. Despite classical CEA leads to good results, in selective cases bypass graft may be the best treatment of in-stent restenosis. Case reports. We describe two cases of carotid bypass graft performed to treat a recurrent in-stent stenosis after CAS for post-CEA restenosis. No death and cardiac complication occurred and no cranial nerves impairment was detected. Conclusion. Prosthetic bypass graft is safe and effective in treatment of in-stent recurrent restenosis after CEA restenosis.

Arterial entrapment syndrome in the cubital fossa: a rare cause of acute stress-related arterial thrombosis in a patient with brachial artery duplication

Arterial entrapment syndrome (AES) at elbow level is very rare and to our knowledge no case of AES by lacertus fibrosus in the cubital fossa in presence of brachial artery duplication has been described to date. We describe a rare case of acute arterial thrombosis of one of two brachial arteries highlighted in the cubital fossa which developed after strenuous right elbow flexor muscle activity and hyper-extensions presumably related to AES by lacertus fibrosus at elbow level. A 43-year-old right-handed woman, experienced paleness, coldness and numbness of the right hand, after 8 consecutive hours of gardening. As she worked, her ipsilateral flexor elbow muscles remained in prolonged and inappropriate tension. Clinical examination evidenced the absence of radial artery pulse in the wrist and mild hypothermia in the second and third finger. During surgical exploration two anastomosed brachial arteries were detected in the cubital fossa under the lacertus fibrosus. The lateral superficial brachial artery was occluded. Intraoperative arteriography evidenced brachial artery duplication at the third superior of the arm and normal vascular pattern at the forearm level. In cases of unexplained atypical intermittent upper extremity claudication or acute ischemic symptoms an AES should always be ruled out, particularly when symptoms are exacerbated by strenuous upper extremity activity or when upper limb muscular hypertrophy is evident. In these cases a thorough dynamic clinical and instrumental examination is mandatory to confirm a diagnosis of AES and to avoid possible future ischemic complications.

Suspecting Renal Artery Thrombosis

Renal artery thrombosis is a threatening clinical diagnosis, in which renal infarction may occur. Often misdiagnosed, for mimicking other common diseases, it should be considered in persistent flank pain to improve care and reduce morbidity. We review a case of a healthy, 57 year-old woman with renal artery thrombosis mimicking pyelonephritis and renal calculus obstruction, highlighting features of this clinical condition. An accurate diagnosis is essential for optimal management and prompts treatment, which still remains to be defined.

Imaging in non Traumatic Emergencies: Acute Thrombosis of the Aorta and Pulmonary Embolism

Objectives: To present the possibility of acute arterial and venous thrombosis. Materials and methods: Report of a patient presenting with acute dyspnoea and chest pain. Results: Using a combined medical team and imaging studies, pulmonary embolism and acute arterial thrombosis were diagnosed. The patient was treated medically and surgically. Conclusion: Physicians should be aware of the possibility of combined thrombosis and the diagnosis and management of the condition.

Deep Venous Thrombosis (DVT) in Lower Extremity Amputation as Cause of Pulmonary Embolism

The authors describe the case of a 43-year-old man with a right-leg knee amputation performed 14 years prior. He presented to hospital with dyspnea. A pulmonary embolism was detected. A Doppler ultrasound test showed deep vein thrombosis (DVT), which affected the stump of the amputated limb. When a pulmonary embolism is detected in a patient with an amputated lower limb, an exploration of the stump should be performed to rule out this uncommon complication.

Left Ventricular Thrombosis in a Young Ulcerative Colitis Patient: Review with a Case Report

Inflammatory bowel disease (IBD) patients are at increased risk of developing thromboembolic complications. We report here a rare case of left ventricle thrombus in a young woman with ulcerative colitis. We discuss the pathophysiology of hypercoagulable state in IBD, and briefly address current prophylactic anticoagulation recommendations.

A Very Big Hand Is a Very Big Problem: Soft-Tissue Infection, Venous Thrombosis, or Just an Insect Sting?

A 67-year-old woman developed severe edema of her right hand and forearm, for which she was treated with antibiotics, without benefit. The echography excluded a venous thrombosis. Subsequently, she referred a wasp sting before the development of the edema. Specific Hymenoptera venom immunoglobulin E (IgE) was found to be positive for paper wasp and yellow jacket. A large local reaction (LLR) was diagnosed due to the hymenoptera sting. Self-injectable epinephrine was prescribed for possible, though unlikely, systemic reactions following hymenoptera stings.

A Case of Internal Carotid Artery Thrombosis associated with Thalidomide Administration in Multiple Myeloma

Thalidomide is an effective chemotherapeutic agent used to achieve remission in multiple myeloma. However, its administration is associated with several adverse effects including venous thromboembolism, while arterial thrombosis has also, although rarely, been described in the literature. We report a case of internal carotid artery occlusion within 1 week of starting thalidomide with prophylactic low molecular weight heparin in a patient who had no other prothrombotic risk factors. It is not known why this complication occurs despite the administration of anticoagulant prophylaxis. The role of factor VIII, von Willebrand factor antigen levels and fibrinogen in multiple myeloma patients should be studied in order to determine if these factors should be targeted in future prophylactic treatment.
