Endovascular treatment of mycotic hepatic artery aneurysm in the hostile abdomen--a case report.

Mycotic hepatic artery aneurysms are rare. This report documents a case in which a mycotic hepatic artery aneurysm was associated with Crohn's disease, renal adenocarcinoma, and a urinary tract infection. Endovascular management of this mycotic hepatic artery aneurysm was successful in the setting of a hostile abdomen based on multiple previous operations, a stoma, and a scarred abdomen.

The tourniquet as a routine adjunct in lower limb revascularization.

The use of a tourniquet as an adjunct for lower limb revascularization is safe, effective and improves visualization of the operative field. Less dissection of the target vessels is required and combined with non-use of clamps and other occluding devices, we project a decrease in host hyperplastic response that will in turn impact favorably on patency rates. The possibility also exists that early failure may be prevented by avoiding application of traumatic forces to diseased and brittle or calcified arteries. Although tourniquet time may have no impact on overall operative procedural time, certain phases of the operation are clearly shortened and facilitated, particularly in complex and difficult reconstructions. Histochemical changes in muscle biopsies do not adversely impact on patients in a clinical sense, but further investigation is required to elucidate subcellular events.

Giant retroperitoneal pelvic hemangiopericytoma.

Hemangiopericytoma is a rare soft tissue sarcoma, comprising less than one percent of all vascular neoplasms. This report describes a 75-year-old man with a very large malignant retroperitoneal hemangiopericytoma that was successfully excised. The tumor measured 23 cm in its greatest dimension and, as such, is the largest malignant hemangiopericytoma reported to date. The clinical and pathologic features of this lesion and a review of the literature are presented.

Dual function of the distal arteriovenous fistula for maintenance of arterial and venous prosthetic graft patency in the lower extremity.

Venous hypertension, severe swelling, and tissue necrosis occurred in a limb previously subjected to distal arterial bypass plus adjunctive arteriovenous fistula. Occlusion of the popliteal vein had not been recognized during the early treatment period. Subsequent to identification of this mechanism, limb salvage was achieved with an interposition graft of the popliteal vein using externally supported PTFE. The prereconstruction venous pressure gradient of 29 cm H2O was virtually abolished immediately after reestablishing venous outflow. The distal arteriovenous fistula, initially established to maintain prosthetic arterial graft patency, now serves, in this case, a dual function by additionally maintaining prosthetic venous graft patency. An intact deep venous system is critical for achieving successful arterial reconstruction and to avoid the complications associated with an occluded outflow tract in the face of augmented inflow.

The use of modified human umbilical cord vein in femoral popliteal reconstruction.

Glutaraldehyde-tanned human umbilical cord veins were employed for reconstruction of the femoral popliteal segment in 80 instances. The primary indication for surgery was imminent loss of limb. The cumulative patency to 20 months was 84.8 percent. The primary mechanism for graft failure was thrombosis usually due to progressive atherosclerosis of the distal circulation (6 cases). There were no instances of infection, dilatation of the graft or aneurysm formation. The data indicate that the results obtained when the glutaraldehyde-tanned umbilical vein in femoral popliteal location are comparable and perhaps even superior to those obtained with the saphenous vein. This suggests that this graft material will be applicable as avascular prosthesis in many instances and will provide for limb salvage and function in patients who face potential loss of limb.
