ABSTRACT

<p><b>BACKGROUND</b>Acute massive pulmonary embolism (PE) is a clinical emergency requiring rapid and supportive measures. Percutanous mechanical thrombectomy is considered as a treatment option. The purpose of this study was to evaluate the clinical efficacy and safety of peructaneous mechanical catheter fragmentation in the management of acute massive PE.</p><p><b>METHODS</b>From January 2003 to June 2007, 28 patients (20 men, 8 women; mean age 64 years) with acute massive PE initially diagnosed by computed tomography and confirmed by pulmonary angiography were treated with inferior vena caval filter placement and percutaneous catheter fragmentation. Twenty-six patients received thrombolytic agents after embolus fragmentation.</p><p><b>RESULTS</b>Technical success was achieved in all patients. The improvement of clinical status and restoration of blood flow in the main branches of the pulmonary artery were seen in 27 patients. Only one case did not benefit from the percutaneous therapy and died from the failure of the surgery. Oxygen saturation increased from (86.2 +/- 4.5)% to (96.1 +/- 3.2)% (P < 0.001) after the interventional procedure. The post-procedure mean pulmonary artery pressure decreased from (34.2 +/- 4.8) mmHg to (25.2 +/- 5.1) mmHg (P < 0.001). During clinical follow-up (range, 1 - 5 years), no patients had recurrence of PE.</p><p><b>CONCLUSION</b>Percutaneous catheter fragmentation combined with thrombolysis is an effective and safe therapy in the clinical management of acute massive PE.</p>

ABSTRACT

In addition to the common complications involving hepatic artery, hepatic vein and biliary tract, which have already been mentioned and discussed in the preceding parts of this article, there are some uncommon complications which have been reported in the medical literature as the case report or as the case- series analysis. This paper sums up these uncommon complications. Part of these uncommon complications can be treated with interventional therapy. It is very important for interventional radiologists to make a further understanding of the different etiology of these uncommon complications occurred after liver transplantation so as to get a comprehensive knowledge about the complications after liver transplantation.

ABSTRACT

Hepatic artery stricture (HAS) after liver transplantation can lead directly to transplanted liver function exhaustion and complications of biliary system. The early diagnosis and treatment are crucial for better prognosis. Doppler ultrasound is the first method of choice, and angiography can give further clear dignosis. The balloon dilatation is still effective for hepatic arterial stenosis. With the more adaptable usage of oronary stent, if possible, would reveal more promising result especially for tortuous stenotic hepatic artery. The vascular reconstruction or repeated liver transplantation is still the effective therapeutic methods.

ABSTRACT

Objective To evaluate the safety and clinical efficacy of system thrombolysis combined with percutaneous catheter thrombus fragmentation and thrombectomy for acute massive pulmonary embolism. Methods Ninteen patients with acute massive pulmonary embolism were treated with IVC filter placement, percutaneous catheter thrombus fragmentation and system thrombolysis combined with anticoangulation using low-molecular-weight heparin.Four of 19 patients underwent adjuvant Stranb Rotarex catheter thrombectomy.Results Twenty-one procedures were performed in 19 patients.Improvement of pulmonary artery patency and initial relief of symptoms immediately occurred in 18 of 19 patients after interventional therapy.The oxygen saturation increased from 86% to 97%.Pulmonary artery pressure decreased from 33? 5mm Hg(1mm Hg=0.133kPa)to 25?5mmHg after interventional therapy(t=13.2,P
