Abstract
PURPOSE The purpose of this study was to evaluate the role and efficacy of the tourniquet in lower limb revascularization. METHODS During a 3-year period, 195 patients underwent 205 infrainguinal reconstruction operations in the lower extremity. These patients underwent bypass with a tourniquet and inflow occlusion (group 1) or bypass without a tourniquet (group 2). The type of infrainguinal reconstruction, tourniquet ischemia time, blood loss, and complications related to tourniquet use were recorded. A subset of patients underwent serial muscle biopsies. Specimens from calf muscle were taken just (1) before application of the tourniquet, (2) before tourniquet release, and (3) once wound closure was initiated. These biopsy specimens were studied by histochemical staining and also analyzed for phosphorylase enzyme, a marker for subcellular ischemia. RESULTS One hundred eleven patients underwent 117 infrainguinal reconstruction procedures in which the tourniquet and inflow occlusion were used. These patients were matched against 84 patients who underwent 88 infrainguinal reconstructions without the use of the tourniquet. Complete hemostatic control in group 1 was obtained in 108 of the procedures (92%). Eight percent of the procedures required minor additional techniques to obtain complete hemostasis; in two instances, the tourniquet was removed because it did not provide hemostasis. Mean tourniquet time was less than 1 hour for all reconstruction groups. There were no instances of neurologic deficit, thrombosis of distal vessels, or vascular injury that was related to the use of a tourniquet. A comparison of the two groups revealed no differences with regard to overall blood loss (P =.63) or duration of operation (P = 0.60), observations that reflect the complexity of the cases rather than the use or nonuse of a tourniquet. When tourniquet control was used, we noted a definite decrease in the time for the distal dissection, because total vascular control with extensive dissection was unnecessary. Histochemical analysis with phosphorylase revealed a conversion of tissue with active enzyme activity to a low level with tourniquet use (P <.05). CONCLUSION The use of a tourniquet for lower limb revascularization is safe and effective and improves visualization of the operative field. Less dissection of the target vessels is required. With a combination of the nonuse 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 exists that early failure may be prevented by avoiding the application of traumatic forces to diseased and brittle or calcified arteries. In this study, tourniquet time had no impact on overall operative procedural time, although certain phases of the operation were clearly shortened and facilitated, particularly in complex and difficult reconstructions. Histochemical changes found in muscle biopsy specimens did not adversely impact patients clinically, but further investigation is required to elucidate subcellular events.

Abstract
PURPOSE The aim of this study was to evaluate the clinical efficacy of everted cervical veins used as patches after carotid endarterectomy. METHODS A prospective nonrandomized comparative analysis was performed on patients with either everted cervical veins or saphenous veins as patches after carotid endarterectomy. Two hundred ninety-six patients underwent 329 carotid endarterectomies during an 8 1/2-year period (1987 to 1995). Saphenous vein patches were used in 125 (38%) cases and everted cervical veins in 167 (51%). These two groups were compared clinically and by sonographic surveillance. The mean follow-up of patients in this study was 27 +/- 11 months. RESULTS No significant differences were noted regarding postoperative morbid events between the everted cervical and saphenous vein patch groups. Even at 5 years the percentage of patients without stroke for both groups exceeded 95%. Duplex surveillance studies also showed comparable percentages of recurrent moderate (50% to 69%) and severe (70% to 99%) stenosis, 5.6% and 6.9%, respectively, for everted cervical vein and 5.4% and 6.5%, respectively, for saphenous vein. Cumulative recurrent stenosis-free rates at 5 and 6 years exceeded 82% for each of the patch study groups. CONCLUSIONS Based on the results of this study everted cervical veins are useful adjuncts to carotid endarterectomy, when patch angioplasty is necessary or desirable. Their performance is comparable to that of saphenous veins. Cervical veins are usually available, even when the saphenous vein is absent or inadequate. In addition, good saphenous veins can be spared and lower extremity excisions avoided.

Abstract
Early discovery of breast cancer in the lactating female will result in improved survival rates. One such marker is the "milk rejection sign," which has rarely been described and consists of the rejection by the nursing infant of the lactating breast that harbors an occult breast carcinoma. Recognition of this particular sign is vital and will enable early diagnosis and improved prognosis.

Abstract
BACKGROUND A retrospective review is given of the authors' experience with a consecutive series of acute small-bowel obstruction unresponsive to medical management. METHODS There were 33 exploratory laparoscopies. The etiology was accurately diagnosed in 100% of the cases. Twenty-five (76%) were secondary to postoperative adhesions, of which 18 (72%) were successfully treated by laparoscopic lysis of adhesions. Minilaparotomy was needed to treat iatrogenic perforation (two), gangrenous bowel (one), and Meckel's diverticulectomy (one). Formal laparotomy was utilized for small-bowel resection (two), malignant adhesions (two), and intolerance of pneumoperitoneum (one). Four cases of incarcerated hernias were treated by conventional herniorrhaphy. RESULTS Overall, 67% of our cases were spared formal laparotomy. CONCLUSION We conclude that laparoscopy is an excellent diagnostic modality in acute small-bowel obstruction, the majority of which can be simultaneously managed laparoscopically. Laparotomy should be reserved for malignant adhesions, surgical misadventure, or when the pathology dictates.

Abstract
PURPOSE Successful use of the distal adjunctive arteriovenous fistula (dAVF) for the enhancement of prosthetic graft patency rates in the crural position is critically dependent on the qualitative and quantitative aspects of the arterial and venous runoff. Precise technical performance of the fistula is equally vital to secure optimal results. The purpose of this study was to determine current prosthetic graft patency and limb salvage rates using a modified version of the common ostium dAVF. METHODS The standard method to create the common ostium variant of dAVF has been modified to improve apposition of the "otomy" sites of the artery and vein, avoid twisting and stenosis by terminating the fistula suture line at the artery-vein junctures, reshaping the ovoid ostium to a rectangular shape, and finally, use of multiple interrupted heel-toe sutures. RESULTS Since 1979 we have created 290 fistulas in 281 patients who required leg revascularization procedures. In different time periods we have documented improving graft patency and limb salvage rates. Fistula patency, reflected by annual attrition rates of 13% to 26% per year, continues as a challenge for long-term results. Current 3-year secondary cumulative graft patency and limb salvage rates by life table analysis are 61% and 74%, respectively. The conduit material may play a role with regard to steal phenomena and the need for banding techniques. CONCLUSION Configuration of the adjunctive dAVF may impact on prosthetic graft patency in the crural position. In addition, the type of graft material used for bypass may be instrumental in preventing or precipitating the steal phenomenon. These issues require further study to better understand flow dynamics, patterns of intimal hyperplasia, and blood distribution as a function of conduit material and impedance of the arterial and venous runoff.

Abstract
Ischemic colitis is an infrequent but potentially devastating complication of abdominal aortic reconstruction. Identification of patients with predisposing risk factors for the development of ischemic colitis can guide intraoperative measures to preserve or restore colonic blood flow during aortic surgery. Previous radiation therapy for pelvic malignancy may be one such predisposing risk factor. Two cases are presented in which ischemic colitis complicated abdominal aortic reconstruction in the setting of previous pelvic irradiation. In the months after radiation therapy for prostate cancer, one patient underwent infrarenal abdominal aortic aneurysm repair. Ischemic infarction of the sigmoid colon developed acutely after surgery and required emergent sigmoid colectomy. The second patient underwent reconstruction of an infrarenal abdominal aortic aneurysm after having had radiation therapy for a bladder tumor. Despite an initial satisfactory result, the patient's abdominal pain and diarrhea progressively worsened and he eventually required sigmoid colectomy for severe ischemic colitis. In both of these patients, the inferior mesenteric arteries were patent and had not been reimplanted. The association of pelvic radiation therapy with ischemic colitis after aortic reconstruction should focus attention to the operative details for maintaining the colonic circulation in these patients. Reimplantation of the inferior mesenteric artery in particular may prevent both the acute and the insidious variants of this complication in patients who undergo aortic surgery and decrease the incidence of this complication in patients with a history of radiation therapy to the pelvis.

Abstract
Cholecystocolonic fistula is an unusual complication of biliary tract disease. Many of the signs and symptoms of these fistulas are nonspecific, so the diagnosis is often not suspected preoperatively. It is important to make the diagnosis then to prevent fecal contamination when the fistula is divided. We recently encountered a patient who, while undergoing laparoscopic cholecystectomy, was found to have a fistula between the gallbladder and the proximal transverse colon. Important features in the management of this case are (1) maintaining a high index of suspicion for the presence of this complication, (2) use of cholecystography to establish the diagnosis, and (3) use of laparoscopic stapling techniques to divide the fistula while preventing fecal soilage.

Abstract
Between November 1990 and November 1992, 50 consecutive cases requiring lower-extremity revascularization by the in situ method were compared with regard to use of two different valve cutters, the Hall valvulotome and the Insitucat. There were no amputations in patients with patent grafts, nor were any infections or false aneurysms noted during the course of this study. In the Insitucat group (n = 25), primary patency was achieved in 19 cases. Five of the six graft failures underwent additional procedures of which three remained patent, adding to the secondary patency rate (22 of 25). The greatest problem with regard to maintaining primary graft patency was that of missed or retained valves, but the incidence of this problem decreased during the course of this study as experience was gained with the catheter in conjunction with angioscopy. Experience with the Insitucat valvulotome has demonstrated its efficacy, though enhanced by monitoring the results with angioscopy. The development and discovery of focal stenotic areas and retained valves by surveillance sonography have resulted in enhanced (assisted) primary graft patency rates. The incidence of these problems appears to be comparable with that occurring with other means of producing valvular incompetence for an in situ reconstruction where valvulotomes of similar design are employed. This was confirmed by comparative analysis with another group of 25 in situ vein bypasses performed during the same time period but during the Hall valvulotome.

Abstract
From November 1979 through December 1989, 210 distal arteriovenous fistulas were constructed as adjuncts to tibial and peroneal vascular reconstructive procedures in 203 patients threatened with limb loss. Two-year cumulative patency rates were calculated by grouping patients on the basis of changing indications in sequential time periods: group 1 (n = 61): 1979 to 1983, 18%; group 2 (n = 80): 1983 to 1986, 33%; group 3 (n = 69): 1986 to 1989, 44%. Although the therapeutic results observed in these groups are not statistically comparable, they show a perceptible trend. Postoperative arteriography showed that flow is prograde in the distal vessels beyond the distal arteriovenous fistula. Graft surveillance by duplex ultrasonography also confirmed that flow in the distal arteries is prograde and that "steal" does not occur. Peak systolic velocity (174 +/- 38 cm/sec) and mean velocity (92 +/- 23) flow rates are increased in grafts with patent distal arteriovenous fistulas compared to those bypasses with closed distal arteriovenous fistulas (p less than 0.01). There were no differences in the flow measurements for the arteries beyond the distal anastomoses and distal arteriovenous fistulas, confirming the prograde nature of the distal flow. In 22 patients analysis of graft and fistula patency by duplex sonography showed that one fourth of all grafts were patent without fistulas at 1 and 2 years after operation. Alternatively, 68% of patent grafts at 1 year had patent fistulas and 58% had patent fistulas at 2 years. We conclude that the distal arteriovenous fistula will increase graft flow and simultaneously prevent distal arterial overload without causing "steal." This technique should be considered whenever a prosthetic graft is necessary for crural reconstruction and only in selected instances of revascularization with autologous veins.

Abstract
Over a 12-year period, 160 transmetatarsal amputations were performed in patients with peripheral vascular occlusive disease. The following groups were defined: group 1 - nonreconstructable disease (n = 40); group 2 - transmetatarsal amputation in conjunction with distal revascularization (n = 99); group 3 - reconstructable disease but transmetatarsal amputation performed without simultaneous revascularization (n = 21). There were nine early deaths in the entire series, for an operative mortality rate of 5.6%. The lowest rate of transmetatarsal amputation healing (24%) occurred in group 1. An 86% healing rate was achieved in group 3, but in seven cases (33%) some type of revascularization was required within 3 months of the amputation. In group 2 the healing rate was 62% but reached 83% where the bypass remained patent for at least 3 months after the amputation. Long-term patency rates also affected healing. Healing was not influenced by the number of local procedures (single vs multiple). The presence of severe infection or extensive necrosis necessitated open transmetatarsal amputation in 89 cases; the remaining 71 amputations involved primary closure. Since many patients were treated at a time when diagnostic modalities as well as the operative indications and techniques differed somewhat from the current practice, much of the information regarding group I patients in particular should be considered as a negative historical control and any conclusion from our data should be adjusted accordingly. Healing after amputation at the transmetatarsal level can be expected in the majority of instances in which revascularization can be performed with predictable patency, even when the standard criteria for performing such amputations are liberalized.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Residual saphenous vein tributaries function as arteriovenous fistulas after in-situ lower extremity bypass. Whether or not all of these tributaries need to be ligated at the time of bypass is controversial since many will close spontaneously. Other consequences of retained fistulas range from local skin problems to diminished graft flow and ultimate graft thrombosis. A complication not previously reported is rupture of a retained arteriovenous fistula. This unusual and potentially catastrophic complication should be discoverable at an earlier stage by periodic graft surveillance by means of duplex sonography. The routine policy of selective ligation of saphenous vein tributaries needs to be reexamined.

Abstract
Interval gangrene, segmental ischemic necrosis proximal to a functioning distal anastomosis, is a rare complication after successful peripheral vascular reconstruction. Previous reports have demonstrated the gravity of this event in that major limb amputation was required in all cases. Two cases are presented to emphasize the need for maintaining segmental collateral circulation after successful distal extremity bypass. Despite a satisfactory result after distal (inframalleolar) bypass of a popliteal aneurysm, one patient had progressive ischemic gangrene of the upper leg and eventually required amputation. The contralateral limb was successfully managed by distal ligation of the superficial femoral artery, which maintained collateral flow from the proximal superficial femoral artery to the knee and leg. The second patient required a microvascular free flap to replace tissue loss and provide vascular graft coverage after initial multiple bypass failures and a final successful remote reconstruction to the dorsal artery of the foot that excluded the popliteal-crural collateral network. Patients with inadequate collateral circulation or disruption of the profundus or geniculate collateral pathways may require revascularization of sequential vascular beds. Recognition of the potential for interval gangrene is essential since the likelihood of its occurrence will increase in proportion to the number of distal bypasses being performed for limb salvage. Although adjunctive procedures will not completely eliminate the possibility of interval gangrene, awareness of this phenomenon with attention to the segmental collateral circulation can decrease the incidence of its occurrence.

Abstract
Because of the theoretic benefits of autologous vein we undertook an investigation to evaluate cervical veins (facial, external jugular) as patch material after carotid endarterectomy. A device that stimulated both circumferential fixation by sutures and radial tension exerted on in vivo patches was constructed to measure burst strength of tissue. Mean bursting pressure for groin saphenous vein (n = 10) was 94.5 +/- 15.1 pounds per square inch (psi), 75.5 +/- 8.9 psi for ankle saphenous vein (n = 10), 83.3 +/- 14.5 psi for everted (double layer) cervical vein (n = 5) and 10 +/- 3.3 psi for single layer cervical vein (n = 5). No significant differences between saphenous vein at any level and everted (double layer) cervical vein, but all were significantly different from single layer cervical vein (p less than 0.05). From June 1987 through November 1989, 19 patients underwent 21 carotid endarterectomies complemented with adjunctive everted cervical vein patch angioplasty. Indications for surgery were asymptomatic stenosis (53%), transient ischemic attack (29%), and cerebrovascular accident with recovery (18%). All patients were studied after surgery with duplex scanning. Asymptomatic recurrent stenosis was observed in one patient. Transient hypoglossal nerve dysfunction occurred in one other patient. One postoperative death occurred as a result of massive aspiration. These results indicate that everted cervical vein is comparable to the saphenous vein in resistance to bursting and can yield similar results as patch material after carotid endarterectomy. Accordingly, saphenous vein can be spared and lower extremity incisions avoided.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Recent developments in vascular surgery suggest that the retroperitoneal approach to the aorta and the use of epidural anesthesia for lower limb revascularization are associated with decreased morbidity and shorter hospital stays. By combining these principles, we sought to determine if retroperitoneal aortic surgery could be performed under epidural anesthesia and if this might be advantageous. Over a 16-month period, 57 patients underwent aortic surgery via the retroperitoneal (n = 33) or transperitoneal (n = 24) approach. In the former, epidural anesthesia was employed in 10 patients, general anesthesia in 3, and combined epidural anesthesia and general anesthesia in the remaining 20. In the transperitoneal group, general anesthesia was employed in 21 patients and combined epidural anesthesia and general anesthesia in 3. Both groups were similar in age and gender, but risk factors were predominant in the retroperitoneal group. With the exception of one death due to aspiration, there were no significant differences between the transperitoneal and retroperitoneal groups with respect to overall morbidity, pulmonary complications, and length of stay in the intensive care unit and hospital. Despite these findings, we favor the combination of epidural and general anesthesia for retroperitoneal aortic surgery. Morbidity was significantly decreased (p less than 0.05) in low-risk retroperitoneal patients when combined epidural anesthesia and general anesthesia were employed.

Abstract
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.

Abstract
Between October 1975 and November 1985, 907 lower limb bypasses were constructed in 715 patients (799 limbs) with glutaraldehyde-stabilized umbilical veins (UV-G) used as the predominant, or sole, graft material. Each reconstruction was classified in one of eight categories depending on the site of the distal anastomosis: above- and below-knee popliteal, anterior and posterior tibial, peroneal, trifurcation, sequential, and crural (tibial or peroneal) bypasses with adjunctive distal arteriovenous fistulas. Primary and secondary cumulative graft patency rates were determined for each category as well as cumulative actual palliation that combines end points of graft failure, amputation, and death. Half-life patencies for popliteal, tibial, and peroneal bypasses were 6.5, 2.3, and 1.7 years, respectively. Perioperative graft thrombosis occurred in 11% of popliteal reconstructions compared with 22% for the crural group. Nonocclusive graft failure caused by infection, aneurysm, or progressive foot gangrene occurred in 87 grafts (8%). The overall infection rate was 4.3%. Anastomotic aneurysms (1.4%) and strictures (2.1%) occurred infrequently as isolated phenomena. The incidence of graft dilatation and aneurysms assumed significant proportion after 5 years (36% aneurysms and 21% dilation); the diagnosis was particularly facilitated by B-mode imaging. Nevertheless, the overall clinical impact of graft degradation remained minimal (6% after 5 years). Twenty-two of 26 graft aneurysms were excised with successful graft replacement achieved in 10. During this 10-year period, our attitudes did change with regard to the indication for UV-Gs in relation to the maturation of infrapopliteal reconstructive surgery, appreciation of the superior results attainable with in situ saphenous vein, recognition of morphologic changes in long-term UV-G implants, and the growing documentation of poor results with polytetrafluorethylene in the crural position. We believe that UV-G is an acceptable alternative to the absent or deficient autologous vein, particularly in patients with limited life expectancy and where expediency may be a critical factor.
