Tibial artery false aneurysm: uncommon result of blunt injury occurring during athletics.

Two young men presented with symptoms following lower extremity injuries sustained in the normal course of participation in sports. One played baseball while the other competed in Tae Kwon Do. One case presented with digital ischemia, the other developed a pulsating hematoma.

Occult deep venous thrombosis complicating superficial thrombophlebitis.

Purpose: To determine whether superficial thrombophlebitis (STP) can extend into the deep venous system (DVS) and whether this may result in pulmonary embolization.

Methods: All venous duplex ultrasound examinations performed in our vascular laboratory to rule out deep venous thrombosis from June 1, 1994, to June 24, 1996, were reviewed.

Results: Of 8313 limbs studied by duplex scanning in 6148 patients, 1756 limbs (21.

Retroperitoneal nonresective staple exclusion of abdominal aortic aneurysms: clinical outcome and fate of the excluded abdominal aortic aneurysms.

Purpose: The purpose of this article was to prospectively study analyses outcome after staple exclusion of abdominal aneurysms with specific follow-up of the excluded aneurysm. Whether these data may predict behavior of aneurysms excluded from the circulation by transluminal grafting procedures is also addressed.

Methods: Staple exclusion of abdominal aneurysms with bypass via retroperitoneal incisions was performed in 100 consecutive patients undergoing elective procedures.

Venous conditions associated with pregnancy.

Pregnancy is associated with several changes in venous physiology. These include relaxation of venous wall tone and increased lower extremity venous pressure. As a result of these changes, varicose veins, spider telangiectasias, purpura, and other superficial findings may develop.

Venous dysfunction of late pregnancy persists after delivery.

Pregnancy is associated with DVT, pelvic thrombophlebitis, and lower extremity varicosities. Pelvic venous compression by the gravid uterus is blamed. A prospective controlled study using plethysmography was performed.

Sartorius muscle coverage for the treatment of complicated vascular surgical wounds.

Sartorius muscle flaps were evaluated in 14 patients treated for complicated groin wounds related to vascular surgical procedures. Particular risk factors for poor wound healing were present in 8 patients, including diabetes, obesity, or poor nutrition in 3 patients; prior radiotherapy to the groin in 2; reoperative groin exposure in 3. Eleven of 14 patients had multiple indications for sartorius flap coverage, including hemorrhage in 5 patients, groin wound sepsis in 3, graft sepsis in 2, wound necrosis in 5, exposure of a reconstruction in 4, treatment of a lymphocele in 1, and treatment of groin irradiation in 2.

Popliteal-to-tibial in situ saphenous vein bypass for limb salvage in diabetic patients.

This study has summarized our results with popliteal-tibial in situ saphenous vein bypass in 26 patients, 25 of whom were diabetic, over a 2 year period. Both above- and below-knee popliteal inflow sites were used for bypass of limb-threatening ischemia. Distal calf or pedal outflow sites were required in all but two patients who had sequential bypass performed to tibial sites.

Lymphatic drainage from the groin following surgery of the femoral artery.

Lymphatic drainage from the surgical wound is uncommon after most surgical procedures. Little data regarding this problem is encountered in the American literature. The incidence of this complication is not established.

Hemodynamics of in situ vein bypass: the role of side branch fistulae.

Ten patients undergoing femoral-popliteal and femoral-tibial in situ saphenous vein bypass for limb salvage were studied to determine the effects of side branch arteriovenous fistulae on flow through the distal end of the graft into the outflow artery. Studies were performed intraoperatively with electromagnetic flow probes. Following completion of proximal and distal anastomoses, flow was established through the graft and measured through its proximal and distal ends.

Salvage of ischemic diabetic feet: role of transcutaneous oxygen mapping and multiple configurations of in situ bypass.

Salvage of ischemic diabetic feet with advanced infrapopliteal and pedal arch atherosclerosis requires distal revascularization to heal skin envelope injuries. A series of 60 consecutive diabetic extremities with 41 nonhealing skin envelopes requiring distal tibial or pedal bypass in 83 percent has been reported. Four configurations of in situ bypass, including femoropopliteal, femorotibial, femoral sequential popliteal-tibial, and popliteal-tibial [3,9,11,17] were utilized with reversed and nonvein bypass to achieve a 93 percent hospital survival rate and 90 percent limb salvage with 80 percent graft patency at 36 months.

Primary lymphoma of the gastrointestinal tract.

Forty-six instances of gastrointestinal tract lymphoma are reviewed with attention to clinical features, diagnostic studies, surgical approach and adjuvant therapy. Gastrointestinal tract lymphoma may be present at any age in individuals with pain, abdominal mass or other abdominal findings, and all ulcers and other endoscopically accessible lesions require biopsy, without regard for roentgenologic or endoscopic appearance of benignity. Resection is recommended when cure is possible; adjunctive therapy is regarded as beneficial.

Effect of cyproheptadine on endotoxin-induced pulmonary platelet trapping.

The adult respiratory distress syndrome (ARDS) seen in endotoxin shock is accompanied by the release of beta-endorphin. The hypotension that is seen in endotoxin shock can also be produced by injection of beta-endorphin and is effectively blocked by the use of antiserotonin drugs. Serotonin injection in dogs causes lung changes similar to those seen in endotoxin shock.

Mesenteric hematoma suggests rupture of visceral artery aneurysm.

A 61-year-old man with nonspecific abdominal pain appeared to have an intramesenteric hematoma by computed tomographic scan. He suffered catastrophic intraperitoneal hemorrhage from a mesenteric branch-artery aneurysm several days later. A mesenteric hematoma, which can be diagnosed noninvasively, suggests a bleeding visceral artery aneurysm, and such findings warrant angiography followed by abdominal exploration if the presence of a visceral artery aneurysm is confirmed.

Effects of adding potassium iodate to milk before UHT treatment. I. Reduction in the amount of deposit on the heated surfaces.

Additions of potassium iodate to milk at 0.05 and 0.1 mM (10 and 20 ppm) before UHT treatment markedly reduced the rate at which pressure built up during processing.

Effects of adding potassium iodate to milk before UHT treatment. ii. iodate-induced proteolysis during subsequent aseptic storage.

The addition of potassium iodate to milk at 9.1 mM before UHT treatment resulted in rapid breakdown of alpha s- and beta-casein during subsequent aseptic storage. Maximum rates of proteolysis were observed at storage temperatures of 37-45 degrees C, but the reaction was strongly inhibited by storage at 55 degrees C and by increased holding time at 140 degrees C during the UHT sterilization.
