Abdominal venography

HEART
JOURNAL
Thrombi produce three types of shadows: In incomplete block, the head of the opaque column is usually concave; when the vein is incompletely obliterated a ragged, irregular area extending for a varying length is seen; finally, the opaque material may outline the walls and show a mass within the lumen. Satisfactory venographic information can be obtained in probably 60 to 90 per cent of cases. Discontinuation of the study too soon in pathologic cases or improper timing of the exposures may possibly account for the greater percentage of failure to obtain adequate information. Blocked vessels or other roentgen findings account for additional failures. ZION.

The patient is prepared in a manner similar to that used in intravenous urography. Sphygmomanometer cuffs are placed about The pressure in the the thighs as proximal as possible, leaving room for femoral venepuncture. cuffs is adjusted to diastolic pressure or slightly higher. Twenty cubic centimeters of a 35 per The rate of cent Diodrast solution are injected through a 18 gauge needle on the side selected. injection is approximately 1.0 C.C. per second. The usual kidney-ureter-bladder exposures are made outlinging the common iliac veins and inferior vena cava. Having the patient hold his breath during the exposure and injection tends to make the blood column move more slowly and smoothly. A Valsalva effort may reverse the flow sufficiently to outline the branches of the iliac veins. The removal of the cuffs releases the dammed-up venous blood from the lower extremities and may wash out or dilute the slightly thrombogenic influence of the Diodrast. ZION.

The author described a technique of abdominal venography. Under local anesthesia the long saphenous vein is exposed by a small incision at the inner portion of the middle third of the thigh. A tourniquet at the groin permits better visualization of the vein which is then punctured with a small trocar. The tourniquet is released and 40 cc. of Diodrast is rapidly injected into The first was made when the vein. Two 14 by 17 inch film exposures of the abdomen are made. 20 to 2.5 C.C. of the opague material has been injected and the second immediately after the completion of the injection. Normal venography visualizes the femoral, external, common iliac veins, and the inferior vena cava. Compression of the epigastric region with an inflated balloon may permit visualization of the renal, hepatic, and internal iliac veins. Indications for abdominal venography are: (1) obstruction vena cava; (2) abdominal tumors, especially renal neoplasms indicated; (3) liver conditions that lead to portal hypertension vein-vena cava anastomosis in order to determine the’integrity
or thrombosis of the inferior where intravenous urography is with the possibility of a portal of the vena cava. In In thrombophlebitis the site of obstruction of the vessels can easily be demonstrated. tumors that compress and displace the inferior vena cava and common iliac veins, the site of compression and displacement together with the establishment of collateral circulation can be demonstrated.
