Treatment goals for deep venous thrombosis include stopping clot propagation and preventing the recurrence of thrombus, the occurrence of pulmonary embolism, and the development of pulmonary hypertension, which can be a complication of multiple recurrent pulmonary emboli. About 30 percent of patients with deep venous thrombosis or pulmonary embolism have ...

PURPOSE: To describe an unusual case involving thrombosis in an aortic endograft limb following microwave therapy (MWT) for lumbar pain. CASE REPORT: A 77-year-old man had successful repair of an abdominal aortic aneurysm with a Vanguard endograft. He had been free of complications during the 3-year follow-up. Five days after ...

Heparin-induced thrombocytopenia (HIT) is of special interest to vascular surgeons as heparin is the predominant anticoagulant used before, during, and after vascular surgery. Further, the prothrombotic nature of this antibody-mediated disorder leads to a high frequency of limb ischemia due to large arterial occlusion by platelet-rich ("white") clots or because ...

Although the factors leading to venous thrombosis have been known for over a century, Virchow's initial model of thrombosis has been extensively refined. Activated coagulation is now recognized to be of primary importance in venous thrombogenesis; the concept of venous injury has been expanded to include molecular changes in the ...

Thromboembolic complications following splenectomy for hematologic diseases occur in up to 10% of patients and may range from portal vein thrombosis (PVT) to pulmonary embolism (PE) and deep vein thrombosis (DVT). Up to now there exist no recommendations for the duration and intensity of prophylactic anticoagulation, which usually follows local ...

May-Thurner syndrome is a well-recognized anatomic variant that is associated with the development of symptomatic acute venous thrombosis of the left iliac vein. However, the natural frequency of compression of the left iliac vein and its clinical significance in asymptomatic disease has not been established. Therefore the purpose of this ...

Triptans are effective and well tolerated in the treatment of acute migraine. Chest symptoms are a common adverse effect unrelated to coronary vasoconstriction in most patients. Although the aetiology of chest symptoms remains to be fully defined, pulmonary vasoconstriction is a possible underlying mechanism. Pre-clinical studies of isolated human blood ...

The roof of the parapharyngeal space (PPS) is poorly defined. Although it is generally described as having prestyloid and poststyloid compartments, we believe that these terms are imprecise. Therefore, we define its boundaries, partition, and compartments. We completed macroanatomical and microanatomical dissections in 10 specimens from 5 human cadaver heads; ...

Upper extremity deep vein thrombosis (UEDVT) is a rare thrombotic disorder (1-4% or all DVT), but it has a potential for considerable morbidity in the form of pulmonary embolism, persistent upper extremity pain and swelling, superior vena cava syndrome and loss of vascular access. Newer non-invasive methods such as duplex ...
Stein Paul D - - 2004
Reports of seasonal variation of the incidence of pulmonary embolism and deep venous thrombosis are inconsistent as to when or if it occurs. We used data from the National Hospital Discharge Survey and the United States (US) Bureau of the Census to test for circannual variation throughout the entire US ...

Deep thigh veins, including the superficial femoral, superficial femoropopliteal, and profunda femoris veins, are versatile autogenous conduits for arterial reconstruction. Although late venous complications are unusual, deep vein harvest may induce severe venous hypertension and predispose the limb to acute compartment syndrome. The purpose of this study was to define ...

Pulmonary embolism (PE) and deep venous thrombosis (DVT) are a continuum and are difficult to diagnose clinically. Combined CT venography and pulmonary angiography (CTVPA) is a single examination that combines multidetector CT pulmonary angiography (CTPA) and CT venography (CTV) of the abdomen, pelvis, and lower extremities, providing "one-stop shopping" for ...

INTRODUCTION: Vein of Galen aneurysmal malformations (VGAM) are assumed to be related to the persistence of the embryonic median prosencephalic vein of Markowski, which does not involute in cases of VGAM and becomes the venous collector of the shunt, characteristic of the malformation. The arterial feeders of VGAMs are all ...

Superficial vein thrombosis may be complicated with venous thromboembolism. We examined factors predictive of venous thromboembolism in superficial vein thrombosis, which, to our knowledge, had not been prospectively studied before. We performed post hoc analysis of the STENOX trial, a prospective randomized controlled trial that investigated various antithrombotic therapies in ...

Congenital absence of the inferior vena cava (AIVC) has been reported as a risk factor of deep vein thrombosis (DVT) in young people. DVT is caused by an interaction between congenital coagulation abnormalities and acquired risk factors. We observed an 18-year-old patient with AIVC who developed recurrent deep vein thrombosis ...

A 34-yr-old male commercial pilot developed a painful swollen right upper arm following an episode of trauma. Venography confirmed the clinical diagnosis of a right axillary deep venous thrombosis. Magnetic resonance imaging suggested the presence of a fibrous tissue band overlying the junction of the right subclavian and innominate veins, ...

The diagnosis of venous thromboembolism, which comprises deep vein thrombosis and pulmonary embolism, remains challenging. Combining pretest probability of disease with the results of noninvasive testing, such as ventilation-perfusion lung scan and duplex ultrasound, can avoid costly and invasive testing with pulmonary angiography and contrast venography in most patients. Techniques ...

Deep venous reflux resolution after great saphenous vein surgery has been reported, but the studies evaluated mainly patients with deep segmental reflux. We prospectively analyzed the effects of greater saphenous vein ablation on coexisting primary deep axial venous reflux compared with segmental venous reflux. Patients and methods Between February 1997 ...

Chronic pulmonary thromboembolism is a rare but treatable cause of pulmonary hypertension. We are describing two patients with limited mobility and dyspnoea. Neither of the patients had clinical evidence of deep vein thrombosis. A high level of clinical suspicion is required for the diagnosis. Spiral CT scan establishes the diagnosis ...

Upper-extremity deep vein thrombosis (UEDVT) was an understudied disease until recently. Previously thought of as benign, UEDVT has been shown in recent studies to pose a significant risk for pulmonary embolus and death. This article reviews the epidemiology, risk factors, clinical features, diagnostic tests, treatment options, complications, and prevention strategies ...

As many as 10% of airline passengers travelling without prophylaxis for long distances may develop a venous thrombosis. There is, however, no evidence that economy class travellers are at increased risk of thrombosis. A suitably powered prospective study, based on the incidence of deep-vein thrombosis (DVT) reported in previous studies ...

Deep inspiration-induced bronchoprotection appears to be a major mechanism through which airway obstruction by spasmogens is avoided. Loss of bronchoprotection is associated with airway hyper-responsiveness. Individuals with allergic rhinitis and no airway hyperresponsiveness develop obstruction after allergen inhalation. To test the hypothesis that deep inspiration-induced bronchoprotection is not active against ...
