1/22. diagnosis and therapy of retroperitoneal abscesses.The surgical importance of the retroperitoneal space is indisputable. Bordered by the transverse fascia, the abdominal and lumbar muscles and the spine, it is in connection with the mediastinum and the subperitoneal area, and may be the site of various processes causing diagnostic and therapeutic problems. Retroperitoneal processes may arise from organs which are completely or partly retroperitoneal (duodenum, kidneys, major vessels). Of these processes the retroperitoneal abscesses are dealt with in the present work.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/22. Malignant thyroid lymphoma presenting as acute airway obstruction.Malignant thyroid lymphoma is an uncommon form of thyroid cancer which most commonly presents in elderly women. Most patients demonstrate a rapidly enlarging mass and may show tracheal deviation on chest roentgenogram. Radioisotopic scanning of the thyroid often demonstrates a "cold" or "cool" process of decreased uptake in the affected area. There is often an underlying lymphocytic thyroiditis process noted. Unfavorable prognosis is related to extracapsular extension, blood vessel wall infiltration, diffuse architectural pattern, and cervical lymph node involvement. We present two unusual cases of thyroid lymphoma presenting with acute airway obstruction and review the literature concerning this subject. One case presented a clinical and radiographic appearance similar to a prevertebral space abscess.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/22. streptococcus milleri and complex groin abscesses in intravenous drug abusers.Intravenous drug abuse is an increasing problem. Septic complications occur frequently at the injection site, especially in the groin where large abscesses around the femoral vessels can threaten life or limb. We report four patients with extensive or complex groin abscesses following attempted self-injection into the femoral vein. streptococcus milleri was cultured from all of these abscesses and prompted a review of the isolation of this organism in this hospital.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/22. Image-guided surgical drainage of medial parapharyngeal abscesses in children: a novel adjuvant to a difficult approach.Surgical drainage of localized infections in deep neck spaces in children is often completed without a high degree of technical difficulty. However, abscess drainage within the superior parapharyngeal space medial to the great vessels is particularly challenging for otolaryngologists. Drawbacks to both the intraoral and external approaches to this area have led us to develop a new adjunctive technique that utilizes intraoperative image-guided technology to augment the intraoral approach. Here we present a case series of 12 children in whom this technique was successfully used.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/22. Embolization of an extracranial internal carotid artery pseudoaneurysm.Deep neck space infections are rarely complicated by pseudoaneurysms of the extracranial internal carotid artery. This condition has a high mortality rate with conservative management and significant morbidity with open surgical techniques. Recent advances in endovascular therapy have allowed embolization of the diseased vessel to be performed with a more acceptable safety profile. We report a case of an extracranial internal carotid artery pseudoaneurysm complicating a deep neck space infection in an adolescent that was treated with selective endovascular embolization. We present the findings of computed tomography, magnetic resonance angiography, and conventional angiography.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/22. Ultrasound of arterial graft surgery complications.The value of gray scale ultrasound in evaluating primary diseases of the abdominal aorta and peripheral vessels has been well documented. However, only limited attention has been given to complications associated with arterial graft surgery. Twelve patients with a variety of complications are reported. These include 10 anastomotic pseudoaneurysms, one abscess, two "aneurysms" in degenerated graft material, and four serous fluid collections around intact Dacron grafts. The latter two complications are previously unreported.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/22. Recognition of retropharyngeal abscess in children.retropharyngeal abscess is a rare deep-neck infection that usually affects young children. Swelling in the neck can lead to sudden and fatal airway obstruction. Enlargement of lymph nodes located between the posterior pharyngeal wall and the prevertebral fascia occurs secondary to infection of the nasopharynx, paranasal sinuses or middle ear. Penetrating trauma or foreign-body penetration may also lead to abscess formation. Common symptoms include fever, swollen neck, difficult swallowing, muffled voice and hyperextension of the head and neck. Lateral neck radiographs confirm the diagnosis. Early surgical treatment prevents serious complications, such as mediastinal spread, aspiration of pus, airway obstruction or erosion into a major vessel.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/22. Coronary embolism and subsequent myocardial abscess complicating ventricular aneurysm and tachycardia.A 62-year-old female experienced a ventricular aneurysm and tachycardia caused by coronary embolism from mitral valve endocarditis. The patient underwent endoventricular patch plasty and cryoablation concomitant with valve replacement and survived without any operative complications. Pathological examination suggested that abscess formation played an important role regarding the disruption of the ventricular wall and development of the ventricular aneurysm and tachycardia. In previous reports, a myocardial abscess caused by a septic embolism has only been diagnosed using postmortem examinations as colony growth around the capillary vessels in the myocardium. We considered that our operation was effective and feasible in such an occurrence.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/22. Combined CNS and pituitary involvement as a primary manifestation of wegener granulomatosis.wegener granulomatosis (WG) is a systemic vasculitis of small and medium vessels. It predominantly affects the upper and/or lower respiratory airway and kidneys. Its pathogenesis is not fully understood. WG relatively frequently affects the nervous system (in 30-50% according to the different studies). Most frequently, it manifests as necrotizing vasculitis that leads to the peripheral neuropathies or to the cranial nerves palsy. Impairment of the central nervous system (CNS) is less frequent and occurs in 2-8% of patients. Three major pathogenetic mechanisms were described: CNS vasculitis, spreading of granulomas from the adjacent anatomical areas (paranasal cavities, orbit etc.), and new formation of granulomas in brain tissue. This case report describes patients in whom WG manifested in the form of localized skin involvement and combined CNS involvement that included pituitary gland. Atypical presentation of WG impedes and slows down the process of diagnosis and emphasizes the need for collaboration between medical specialists.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/22. Complications relating to intravenous buprenorphine abuse: a single institution case series.INTRODUCTION: We present a retrospective descriptive study of cases admitted to Tan Tock Seng Hospital from March 2005 to October 2005 with complications of Subutex abuse. CLINICAL PICTURE: A total of 8 patients were studied. Of the 8, 7 were male and one was female. Their complications consist of the following: arterial pseudoaneurysm (2), arterial pseudoaneurysm with infective venous thrombus (1), infective venous thrombus (1), venous thrombus (2), end arterial spasms (1) and sympathetic dystrophy (1). TREATMENT: For the patient who presented with buprenorphine-associated neuropathy, non-operative treatment with analgesics was given. Conservative medical therapy involving deep venous thrombosis treatment was instituted for the patient with deep venous thrombosis. Repair, restorative bypass and embolectomy surgery were performed for patients who had severe embolic/thrombotic complications. One of the patients who received the above surgery required amputation of his lower limb. OUTCOME: Of the 8 patients, 4 were treated medically, 3 required surgery and 1 required amputation. Their recoveries were uneventful. Of the 8, 1 absconded and was not followed up with. CONCLUSION: Parenteral injection of buprenorphine can cause a wide range of vascular complications from simple vascular irritation to severe infective thrombosis and pseudoaneurysms requiring limb amputations. Non-sterile preparation of an injected substance or non-sterile injection sites and the repeated punctures of major vessels are possible culprits in those who are seen to have acute infection of injection sites.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
