Percutaneous balloon occlusion of surgical arteriovenous fistulae following venous thrombectomy.

We describe a percutaneous method of balloon occlusion of surgically created femoral arteriovenous fistulae (AVF) after thrombectomy for acute iliofemoral venous thrombosis. The technique was successful in permanent obliteration of the AVF in 25 of 27 patients. Complications were few, minor, and limited to the developmental period of the procedure. No patient required surgical intervention. The procedure provides an opportunity to angiographically evaluate the results of previous thrombectomy.

Radionuclide angiography in the evaluation of iliofemoral venous patency.

Radionuclide angiography (RNA), was compared to contrast phlebography (CP) for evaluation of iliofemoral venous patency. Twenty-three patients that six months earlier had been treated for iliofemoral venous thrombosis were investigated. The reproducibility of RNA was good as the interindividual and intraindividual variation was 80-85% and 90-95% respectively. The sensitivity of RNA was 91% in the iliac and 65% in the femoral segment. The specificity was 78% in the iliac and 74% in the femoral segment. The advantages as compared to CP are: easy performance, easy to repeat, no adverse reactions and visualization of the whole venous system. The disadvantages are: e.g. difficulties in interpretation in bilateral disease or abnormal anatomy. RNA is recommended as a screening method for suspected iliac venous obstruction and for follow-up of venous patency after iliofemoral venous thrombosis.

Temporary extracorporeal perfusion of the splanchnic circulation dependent on the Riolan anastomosis.

A thorough investigation of a hypertensive 25 year old male was undertaken due to the finding of an absent right radial pulse. This work-up revealed widespread, largely asymptomatic arterial disease characterised by a combination of multiple sites of stenosis and occlusion, aneurysmal dilatation and extensive vessel wall calcification. The findings included a right renal artery stenosis, an abdominal aortic aneurysm and a splanchnic vasculature completely supplied by the inferior mesenteric artery. Consequently it was thought that a prolonged clamping time during the aortic repair would possibly result in ischemic injury. Therefore, the splanchnic organs were perfused by a paediatric oxygenator and pump during the aortic cross-clamping. This case report discusses the etiology of the disease and the technical aspects of splanchnic perfusion.

Etiologic spectrum in acute iliofemoral venous thrombosis.

To identify common etiologies and allow a selective and effective management of acute iliofemoral venous thrombosis, 128 patients treated surgically (97 cases) or medically (31 patients) were analysed regarding possible underlying conditions. Chart review revealed that prolonged immobilization (25%), recent surgery (20%), and neoplasm (16%) were the most frequent etiologic factors. No underlying cause was detected in 34% of the patients, but more than one possible etiology were recorded in 29% of the patients. Chronic compression of the iliac vein was present in at least 13% of the operated cases. The multifactorial etiologic spectrum in iliofemoral thrombosis is basically the same as in calf vein thrombosis. Iliac vein compression, childbearing and perhaps estrogen intake seem to be more often associated with iliofemoral thrombosis. Initial survey regarding underlying causes permits tailored management for the individual patient. Surgical treatment is often successful but thrombi that develop secondary to chronic vein obstruction or neoplasm are preferably treated conservatively.

Thrombectomy and temporary AV-fistula in iliofemoral vein thrombosis. Technical considerations and early results.

Seventy patients with iliofemoral vein thrombosis were operated on with thrombectomy and a temporary arteriovenous fistula (AVF). Diagnosis was always verified with a three-stage venography. The result of the treatment was evaluated with arteriovenography before closing the AVF at a second operation. The AVF stayed patent in 85% and occluded in 15% of the evaluated 60 legs. In patients with patent AVF the common femoral and iliac veins were normal in 37% and in 51% there was a stenosis in either of these veins. Occlusion of the veins in spite of patent AVF was found in 12%. No major pulmonary embolism occurred. The most common complication was wound infection (26%). Technical details of the operative procedure experienced from this study are stressed in the paper.
