Epinephrine enhanced renal angiography in the diagnosis of hamartoma (angiomyolipoma): a reevaluation.

The vlue of epinephrine enhanced angiography in the preoperative distinction of isolated hamartoma (angiomyolipoma without stigma of tuberous sclerosis) from hypernephroma has been largely discounted in the past. The authors performed this procedure in 6 patients (4 with isolated hamartoma and 2 with tuberous sclerosis complex). Vasoconstriction of the tumor vessels in the isolated group suggested the benign nature of the hypervascular mass in all cases. Vasoconstriction stronger than that of normal parenchymal vessels suggested the diagnosis of isolated renal angiomyolipoma. This form of pharmacoangiography should be part of the routine preoperative workup of all solid renal masses.

Selective angiography in renal and peri-renal inflammatory lesions: correlation with histopathology.

We have correlated the angiographic and pathological findings in renal and peri-renal inflammatory disease in acute, sub-acute and chronic phases. In all stages of renal infection, the renal vasculature is attenuated. This corresponds in acute inflammation to vasospasm, acute vascular necrosis and post glomerular peritubular capillary congestion. In sub-acute inflammation, the reduction in vascularity is due to peri-vascular fibrosis and intimal and medial hyperplasia. In chronic infections, the renal vessels are completely destroyed and replaced by fibrotic tissue. In contrast to this, peri-renal inflammatory disease leads to vaso-dilatation and enlargement of the renal capsular arterial complex, and of retroperitoneal arteries. If both renal and peri-renal inflammation occurs simultaneously, a discordance between the renal cortical and capsular arterial filling results: this striking phenomenon is highly suggestive of inflammation, and extremely rare in tumours. Three types of inflammatory vascularity are described, two of which can be easily distinguished from tumour vascularity. An inflammatory blush, slow emptying of vessels and a mottled nephrogram with loss of cortical definition are highly suggestive signs of renal inflammation. It is concluded that angiography is a sensitive and accurate method for the early diagnoses of renal and peri-renal flammatory conditions.

The hypernephroma halo.

Most renal adenocarcinomas (hypernephromas) are characterized histologically by a dense, avascular, fibrous capsule. This capsule is rare or nonexistent in other benign or malignant renal tumors. The capsule was identified as a thin radiolucent stripe surrounding parts of the tumor periphery in 30 renal angiograms performed on a group of 70 patients with pathologically proven hypernephromas. Only one of 65 normal kidneys and 137 other benign or malignant renal tumors or pseudotumors exhibited angiographic evidence of this lucent stripe. This stripe is therefore referred to as the "hypernephroma halo." Its identification on an excretory urogram is occasionally possible; in five patients it was recognized prior to angiography suggesting the lesion causing it is a hypernephroma.

Use of a curved multi-hole catheter for abdominal and femoral arteriography.

A single-curve 6.5 French polyethylene catheter with an endhole and multiple sideholes is routinely used by the authors for abdominal aortography and femoral arteriography. It allows excellent simultaneous visualization of both renal arteries and intrarenal vasculature. When withdrawn to the aorto-iliac bifurcation, it allows virtually selective bilateral femoral artery visualization in the evaluation of peripheral vascular disease.

Surgical treatment of the celiac axis compression syndrome.

Six patients with symptomatic celiac axis compression syndrome are reported on. Four were treated surgically with arterial reconstruction. None of these four patients was benefited more than temporarily by the corrective surgery. One patient had an abdominal exploration and highly selective vagotomy unrelated to the celiac axis and is symptom-free ten months after surgery. One patient had no surgery and remains symptomatic. Angiographic evaluation in all patients demonstrated that despite high grade stenosis of the celiac axis, there was no radiographically discernible reduction in constrast flow to the celiac axis because of well developed collaterals from the superior mesenteric artery. These results indicate that compression of the celiac axis may be merely an incidental angiographic finding, so this syndrome needs cautious evaluation.

Splenoportography--a valuable diagnostic technic, revisited.

The value of splenoportography in evaluating patients with portal hypertension was assessed. The technic was found to be useful in estimating portal-venous pressure, ruling out portal vein thrombosis, evaluating the superior mesenteric and portal veins as to their suitability for shunt procedures, and defining anatomy and collateral pathways. Splenoportography is a relatively simple procedure which provides excellent visualization of the portal venous system. Other methods may require special expertise and may not yield sufficient diagnostic information.

Emergency embolization in blunt hepatic trauma.

The right hepatic artery in a patient with traumatic liver tear was embolized with Gelfoam to stop an otherwise uncontrollable hemorrhage. The procedure was probably life saving in this patient. Transient elevated transaminase and bilirubin levels returned to normal 3 weeks after embolization. A repeat hepatic arteriogram 4 months after embolization demonstrated good revascularization of the right hepatic lobe from the left hepatic, left gastric, and gastroduodenal arteries. This case demonstrates the therapeutic value and safety of selective hepatic arterial branch embolization in massive life-threatening hemorrhage.

Polyarteritis nodosa causing severe intestinal bleeding.

Rupture of an aneurysm of the mesentergic artery caused severe intestinal hemorrhage in a 50-year-old woman with polyarteritis nodosa. Abdominal angiography not only established diagnosis of polyarteritis nodosa by demonstrating multiple visceral aneurysms but also localized the site of bleeding.

Transcatheter gelfoam embolization in intractable prostatic bleeding.

The authors describe a case in which protracted bleeding after a transurethral prostatic resection could not be controlled with repeated fulguration and resection. Hemostasis was obtained with transcatheter arterial Gelfoam embolization of both hypogastric arteries.
