MR angiography of the iliac and upper femoral arteries using four different inflow techniques.

OBJECTIVE: The purpose of this study was to compare two inflow MR angiography pulse sequences obtained with and without systolic synchronization. We also compared these two MR angiography pulse sequences with conventional angiography. SUBJECTS AND METHODS: Thirty-one consecutive patients who were scheduled for conventional angiography because of symptomatic atherosclerotic occlusive disease of the iliac or femoral artery underwent MR angiography using four different MR angiography techniques. These techniques consisted of a multiple two-dimensional inversion prepulse gradient-recalled echo technique (turbo field-echo) obtained with and without systolic synchronization and a multiple two-dimensional gradient-recalled echo technique (fast field-echo) obtained with and without systolic synchronization. We then compared image quality and our ability to detect and grade degree and length of stenosis, using conventional angiography as the gold standard. RESULTS: The systolic-synchronized turbo field-echo sequence produced the best results both objectively and subjectively. Comparing systolic-synchronized turbo field-echo and fast field-echo techniques with conventional angiography regarding detection and grading degree of stenoses, we found no statistically significant differences. CONCLUSION: Systolic synchronization proved to be of significant importance for image quality. The systolic-synchronized turbo field-echo pulse sequence proved to be superior to the other three MR angiography techniques.

Systemic to pulmonary vascular malformation.

A case is reported of life-threatening haemoptysis as a result of an anomalous communication between a bronchial artery and pulmonary vein, demonstrated by angiography. The patient recovered following bilobectomy of the right lower and middle lobes. When a systemic artery is involved in an arteriovenous malformation of the lung, haemodynamics are different compared with those present in malformations fed by the pulmonary artery. This implicates other clinical features, options for surgical intervention and prognosis. In reviewing the literature, a relationship with Rendu-Osler-Weber disease is absent in these specific malformations.

A forme fruste of Marfan's syndrome: case history.

A thirty nine year old woman presented with multiple aneurysms and dissections of the arterial system secondary to cystic medial necrosis is presented. After assessment of the family history a diagnosis of a forme fruste of Marfan's syndrome was made. Preoperative consideration of this rare diagnosis is important for treatment and surgical management.

Left renal vein compression syndrome ("nutcracker phenomenon").

Four cases are presented with clinical diagnosis of scrotal varicocele on the left side, and one case with ureter varices and left-sided haematuria as a result of compression of the left renal vein between the aorta and superior mesenteric artery (SMA), also known as "nutcracker phenomenon". The clinical signs and the radiological diagnostic methods of the condition are discussed.

Primary arteriovenous fistula between common iliac vessels: ultrasound, computer tomographic, and angiographic findings--a case report.

A giant aneurysm of the right common iliac artery presenting with an arteriovenous fistula (AVF) between the iliac artery and iliac vein and deep venous thrombosis of the right lower extremity is reported. The clinical signs and the radiologic and surgical management of the condition are discussed. In addition a brief review of the literature is given.

Popliteal artery entrapment syndrome.

Two patients with unilateral popliteal artery entrapment syndrome (PAES) are reported. The importance of diligence in angiographic diagnosis and recognition of the so-called "functional" PAES group as a separate entity are stressed. It is inferred from our material that a surgical approach for PAES is to be advocated since surgical release of the entrapment can lead to complete resolution of symptoms regardless of aetiology.

Sequential PTA of abdominal aorta. Haemodynamic evaluation and IV-DSA follow-up.

A case of sequential dilatation of a subtotal stenosis of the abdominal aorta in a young subject is reported. Initial and long-term success of the procedure is recorded using haemodynamic evaluation and intravenous digital subtraction angiography (IV-DSA) follow-up on an outpatient basis. In addition, the significance of biplane aortography with IV-DSA is illustrated.

More accurate assessment of stenotic lesions in percutaneous transluminal angioplasty.

Eighty patients underwent percutaneous transluminal dilatation and recanalisation of atheromatous lesions of the arteries of the lower extremities in the University Hospital of Maastricht in the period of 1980 to 1984. Out of 80 attempted procedures of the iliac and femoro-popliteal tract 71 (89%) were technically possible and were considered initially successful. In all cases of iliac artery lesions a retrograde arteriogram was performed prior to PTA. Intra-arterial pressure measurements at rest and after hyperemia were used for exact assessment of the hemodynamic significance of the stenosis before and after PTA. A follow-up of all patients successfully treated by angioplasty was performed. The early hemodynamic success rate of PTA for iliac lesions was 90 per cent and for femoral-popliteal segment 83 per cent. There was no morbidity or mortality. The cumulative 3-year patency rate for both segments was 74 per cent.
