1/56. may-thurner syndrome in an adolescent: persistence despite operative management.We describe a patient with may-thurner syndrome who underwent operative transection and transposition of the right common iliac artery without direct venous repair, because preoperative and intraoperative intravascular ultrasound scans were negative for "spurs" in the left common iliac vein. When symptoms and signs persisted, a postoperative magnetic resonance venogram (MRV) showed severe stenosis in the left common iliac vein. Progressive, but incomplete, clinical improvement occurred with conservative management.- - - - - - - - - - ranking = 1keywords = syndrome (Clic here for more details about this article) |
2/56. Peripheral vascular disease in Behcet's syndrome.We describe a patient with Behcet's syndrome who had peripheral vascular disease involving the left subclavian artery for which angioplasty with stent placement was performed and reangioplasty done for in-stent restenosis. She presented with recurrence one year after stent placement; angiography revealed diffuse disease of the axillary and radial arteries with mild to moderate restenosis at the site of stent placement.- - - - - - - - - - ranking = 1keywords = syndrome (Clic here for more details about this article) |
3/56. Functional entrapment of the popliteal artery.A case of functional entrapment missed at the initial angiogram is presented. The imaging of popliteal artery entrapment syndrome and functional entrapment is discussed. The importance of appropriate imaging is emphasized. The classification of popliteal artery entrapment syndrome is discussed and it is proposed that functional entrapment is added to the existing classification in the interest of consistent reporting.- - - - - - - - - - ranking = 0.4keywords = syndrome (Clic here for more details about this article) |
4/56. popliteal artery entrapment syndrome: diagnosis and management, with report of three cases.popliteal artery entrapment syndrome is an important albeit infrequent cause of serious disability among young adults and athletes with anomalous anatomic relationships between the popliteal artery and surrounding musculotendinous structures. We report our experience with 3 patients, in whom we used duplex ultrasonography, computed tomography, digital subtraction angiography, and conventional arteriography to diagnose popliteal artery entrapment and to grade the severity of dynamic circulatory insufficiency and arterial damage. We used a posterior surgical approach to give the best view of the anatomic structures compressing the popliteal artery. In 2 patients, in whom compression had not yet damaged the arterial wall, operative decompression of the artery by resection of the aberrant muscle was sufficient. In the 3rd patient, operative reconstruction of an occluded segment with autologous vein graft was necessary, in addition to decompression of the vessel and resection of aberrant muscle. The result in each case was complete recovery, with absence of symptoms and with patency verified by Doppler examination. We conclude that clinicians who encounter young patients with progressive lowerlimb arterial insufficiency should be aware of the possibility of popliteal artery entrapment. early diagnosis through a combined approach (careful physical examination and history-taking, duplex ultrasonography, computerized tomography, and angiography) is necessary for exact diagnosis. The treatment of choice is the surgical creation of normal anatomy within the popliteal fossa.- - - - - - - - - - ranking = 1keywords = syndrome (Clic here for more details about this article) |
5/56. Acute thrombotic thrombocytopenic purpura following abdominal surgeries: a report of three cases.Acute thrombotic thrombocytopenic purpura (TTP) occurred in three patients following abdominal surgeries. One patient underwent extensive lysis for intestinal adhesions with bowel resection, another cholecystectomy for acute cholecystitis, and the third right colectomy and partial intestinal resection for colon cancer. The diagnosis of acute TTP was established on the basis of absent hematologic features of TTP prior to surgery and development of microangiopathic hemolytic anemia (MAHA), thrombocytopenia, and unexplained mental changes after surgery. Hematologic evidence of TTP developed 3 to 9 days after surgery. Other clinical features were acute respiratory distress syndrome (ARDS) in two patients and peripheral digit ischemic syndrome (PDIS) also in two patients. In all three patients, establishing the diagnosis of TTP was delayed. Exchange plasmapheresis in one patient was ineffective due to associated ARDS and two others died soon after the diagnosis was established. In view of our experience, postoperative TTP should be considered in the differential diagnosis of the patient who develops unexplained anemia and thrombocytopenia following an abdominal surgery. Presence of hemolytic anemia, schistocytosis, and unexplained thrombocytopenia should alert the possibility of TTP.- - - - - - - - - - ranking = 0.4keywords = syndrome (Clic here for more details about this article) |
6/56. Progressive appearance of overlap syndrome together with autoantibodies in a patient with fatal thrombotic microangiopathy.We describe an extraordinary patient with overlap syndrome (systemic lupus erythematosus, systemic sclerosis, and rheumatoid arthritis) having positive autoantibodies against Sm, double stranded dna, dna topoisomerase I, and centromere, together with rheumatoid factor. The patient had multiple organ involvement resulting from thrombotic microangiopathy that mimicked so-called normotensive scleroderma renal crisis, and died mainly of massive pulmonary hemorrhage caused by thrombotic thrombocytopenic purpura. The clinical presentations of the case support the concept of strong associations between disease-specific autoantibodies and clinical features.- - - - - - - - - - ranking = 1keywords = syndrome (Clic here for more details about this article) |
7/56. susac syndrome: microangiopathy of the retina, cochlea and brain.BACKGROUND: susac syndrome is characterized by the triad of branch retinal arterial occlusions, encephalopathy and cochlear microangiopathy. The underlying process is believed to be a small vessel vasculitis causing microinfarcts in the retina, brain and cochlea. methods: Analysis of two male and two female cases of susac syndrome recognized in australia. RESULTS: In this series the epidemiology, mode of presentation, ophthalmologic features, neurologic and cochleo-vestibular features, radiologic characteristics, cerebrospinal fluid findings, therapeutic interventions, clinical course and outcome of susac syndrome is examined. Key ophthalmologic differential diagnoses include systemic lupus erythematosis (SLE), Behcet's syndrome and other vasculitides such as sarcoidosis, tuberculosis, syphilis and lymphoma. Neuro-otologic features are most frequently misdiagnosed as multiple sclerosis. CONCLUSION: susac syndrome, first described in 1979, is becoming an increasingly recognized condition. Early recognition of the syndrome is important because treatment with systemic immunosuppression may minimize permanent cognitive, audiologic and visual sequelae.- - - - - - - - - - ranking = 2keywords = syndrome (Clic here for more details about this article) |
8/56. Hypothenar hammer syndrome after radial forearm flap harvest: a case report.A case of acute hypothenar hammer syndrome (HHS) in a high-risk laborer in whom the radial artery had been surgically removed during a prior radial forearm flap harvest is reported. Studies estimating the true incidence of HHS among laborers are reviewed to define the risk of this complication. Two major risk factors must be considered in the assessment of a patient for radial forearm flap harvest. First, the risk for immediate vascular compromise is determined by using a standard Allen's test to assess ulnar artery contribution to hand perfusion. Second, the risk for future vascular compromise is determined. When patients at high risk for HHS are recognized the surgeon should consider other reconstructive alternatives. If the superficial palmar arch is patent and complete and a radial forearm flap is performed, postoperative activity modification and risk counseling should be provided.- - - - - - - - - - ranking = 1keywords = syndrome (Clic here for more details about this article) |
9/56. Successful treatment for the IVC syndrome due to recurrence of colon cancer--chemotherapy in combination with the use of the expandable metallic stent placement.A 73-year-old woman developed severe edema of the abdominal walls and legs due to rapid regrowth of unresectable paraaortic lymph node metastasis from ascending colon cancer. The expandable metallic stent was placed at the site of stenosis. Following the stent placement, she had marked improvement in her urinary output, ascitic drainage and edema of the lower extremity. Subsequently, intravenous infusion of 5-fluorouracil with high-dose leucovorin was performed. The irritable symptom disappeared completely after 5 weeks, and the patient recovered the ability to walk. The patient is alive 22 months after primary noncurative operation. Symptoms did not recur 4 months after the placement of the stent. The authors recommend the multimodality for palliation therapy in unresectable colorectal cancer.- - - - - - - - - - ranking = 0.8keywords = syndrome (Clic here for more details about this article) |
10/56. Aggravation of the nutcracker syndrome during pregnancy.BACKGROUND: The nutcracker syndrome is a rare condition thought to be caused by compression of the left renal vein between the descending aorta and the superior mesenteric artery. CASE: Gross hematuria appeared in the third trimester of an otherwise normal pregnancy. It continued despite treatment, and a cesarean was performed at 37 weeks' gestation. The hematuria stopped postpartum. With postpartum angiography and three-dimensional computed tomography, the diagnosis of nutcracker syndrome was finally made. CONCLUSION: pregnancy can aggravate the nutcracker syndrome. This syndrome should be recognized as one of the diseases that causes gross hematuria.- - - - - - - - - - ranking = 1.6keywords = syndrome (Clic here for more details about this article) |
