Saphenous vein bypass pseudoaneurysm is rare but fatal complication after coronary bypass surgery. Pseudoaneurysm is managed either with a surgical or percutaneous approach. This patient underwent quadruple coronary artery bypass grafting 10 years earlier and was referred for recurrence of angina. Coronary and graft angiography revealed a pseudoaneurysm in the saphenous vein graft supplying the...

We present the case of a 32-year-old male with a delayed symptomatic left subclavian artery pseudoaneurysm secondary to protruding screws from prior perpendicular clavicular plate fixations. The pseudoaneurysm development and our operative approach are unique to the few similar cases available in the literature. The patient presented with a progressive pulsatile mass behind his left clavicle as...

OBJECTIVE The objective of this study was to determine the sequential CT findings of controlled hepatocellular carcinoma (HCC) with main portal vein (MPV) thrombosis with the use of transcatheter arterial chemoembolization and additional intra-arterial cisplatin infusion. MATERIALS AND METHODS From January 2004 to September 2006, 138 patients with HCC invading MPV were referred to the angiogr...

A 61-year-old man with acute myocardial infarction developed a painful hematoma in his groin after percutaneous coronary intervention. Ultrasonography, including color Doppler, detected a pulsatile, hypoechogenic, single compartment lesion (2.3 3.0 2.9 cm) consistent with a partially thrombosed pseudoaneurysm originating from the distal part of the common femoral artery (Figure, A). Sampling fr...

background all conditions that interfere with blood flow at any level within the portal system can lead to portal hypertension. for better management of this disorder, it is important to determine the underlying cause. in previ­ous studies, extra-hepatic disorders have been reported as the main cause of portal hypertension in children. in this study, we investigate the under­lying causes of por...

BACKGROUND Hepatocellular carcinoma (HCC) has a high predilection for portal vein invasion, and the prognosis of HCC with malignant portal vein invasion is extremely poor. The objective of this study was to investigate the outcomes and the prognostic factor of recurrence in HCC patients with malignant portal vein invasion. METHODS We retrospectively reviewed the clinicopathologic data and out...

Portal vein tumor thrombus is a frequent, challenging complication in hepatocellular carcinoma. Hepatocellular carcinoma patients with portal vein tumor thrombus may show worse liver function, less treatment tolerance and worse prognosis than patients without portal vein tumor thrombus, and they may be at higher risk of comorbidity related to portal hypertension. Western and some Asian guidelin...

BACKGROUND Associating liver partition with portal vein ligation for staged hepatectomy induces more extensive liver hypertrophy than ligation alone; however, the mechanisms underlying the accelerated liver regrowth and the functional quality of the hypertrophic liver are presently elusive. This study, therefore, investigated the effect of parenchymal transection on liver volume and function af...

The accuracy of non-invasive radionuclide angiography in detecting portal vein occlusion was assessed in 61 patients--10 with portal vein occlusion confirmed by conventional portography, 25 with chronic liver disease and a patent portal vein (mild = 12, severe = 13), and 26 with normal liver function, who served as controls. The median percentage portal venous flow for the portal vein occlusion...
