Among the 652 consecutive renal transplants performed from January 1973 through December 1988, all graft failures within 60 days of transplantation were retrospectively analyzed. The 53 early failures were divided into four groups on the basis of pathologic findings in the removed transplant). 1) Irreversible vascular rejection (17 cases); in ten patients, this rejection occurred between the fourth and eight days and was manifested by uniform clinical features. 2) Thrombosis of the renal artery (18 cases), with several subgroups: a) early postoperative thrombosis (5 cases) with primary anuria; b) thrombosis following reoperation (6 cases) for urine leakage or occlusion; c) thrombosis with a clotting disorder,; d) and five cases of thrombosis with clinical manifestations of vascular rejection but with isolated thrombosis upon histologic examination. 3) Thrombosis of the renal vein (12 cases), with primary anuria in nine cases, and rupture of the kidney in three. 4) The last group includes six cases due to a variety of causes: one immediately non-viable -kidney, two severe, irreversible cases of tubulonephritis, one cortical necrosis secondary to circulatory collapse in the recipient, one complete necrosis of the ureter requiring removal of the transplant, and one immediate recurrence of hemolytic uremic syndrome. Among the risk factors for early failure, attention is drawn to the young age of the donor or recipient that increases the risk of thrombosis. Furthermore, the risk of vascular rejection was decreased in patients preventively treated by OKT3.

Renal autotransplantation with/without extra-corporeal surgery was performed in 53 patients between September, 1975 and december, 1987. Original disease was obstructive disease of the upper urinary tract in 25 patients, renovascular hypertension and renal vascular disease in 13, renal calculous disease in 12 and renal cell carcinoma in 3. Ten of the 53 patients had solitary kidneys. Three patients died on 14, 21 and 49 postoperative days of massive bleeding with disseminated intravascular coagulopathy caused by the rupture of transplant arterial anastomosis (1 patient with urinary obstructive disease) and sepsis caused by wound infection (2 patients with renal calculous disease). Two kidneys were removed on operative day and 8 postoperative days due to arterial thrombosis in 2 patients with aneurysm of intrarenal artery. The deterioration of renal function was observed in previously damaged kidneys of two patients with extensively damaged ureter. No other severe complications were observed. In 23 of 24 patients with the obstructive disease of the upper urinary tract, disappearance or improvement of the obstructive change was observed after surgery. All 5 patients with renovascular hypertension showed normo-tension without administration of antihypertensive drugs after surgery. In 3 of 5 patients with an aneurysm of the intrarenal artery, the aneurysm was removed and reconstruction of the artery was performed successfully. Two patients with arterio-venous fistula and one patient with nut cracker syndrome had no severe hematuria with bladder tamponade after surgery. Ten of 12 patients with renal calculous disease were treated successfully without residual calculi by this procedure. Three patients who had solitary kidney with renal cell carcinoma were treated successfully by this procedure.(ABSTRACT TRUNCATED AT 250 WORDS)

Injuries missed at initial operation have the potential to cause the most disastrous complications in trauma patients. Over the past 5 years, 12 patients have required re-operation for 14 injuries missed at initial laparotomy and/or thoracotomy. Six missed injuries were vascular, two each in the thorax, pelvis, and retroperitoneum. The other eight were visceral: three small bowel (one patient), two pancreatic, and one each of the heart, ureter, and diaphragm. Five patients (42%) died, three with missed vascular and two with missed visceral injuries. Three died due to complications directly related to their missed injuries, while the unrecognized injury did not play a significant role in the other two. Indications for re-operation in patients with vascular injuries were hypotension in two patients, persistent output from drains in three, and refractory acidosis in one. Re-exploration in visceral injuries was for clinical sepsis in three patients, DIC in one, cardiac tamponade in one, and persistent chest tube drainage in one. Eleven of the 12 patients presented to the E.D. in shock. All patients had multiple injuries with a mean of 3.25 organ systems injured. Hypotension, coagulopathy, and/or hypothermia (T less than 92 degrees) were felt to have contributed to missing the injury in five of the patients with vascular, and three of the patients with visceral injuries. In the four other patients, injuries were missed due to inadequate exploration or a low index of suspicion in the presence of multiple injuries.(ABSTRACT TRUNCATED AT 250 WORDS)

An experience with 31 patients who developed major bleeding diatheses during laparotomy was reviewed. Management of the initial 14 patients was by standard hematologic replacement, completion of all facets of operation, and then closure of the peritoneal cavity, usually with suction drainage; only one patient survived. The subsequent 17 patients had laparotomy terminated as rapidly as possible to avoid additional bleeding. Major vessel injuries were repaired; ends of resected bowel were ligated; and holes in other gastrointestinal segments and the bladder were closed by purse-string sutures. One patient had a ureter ligated. Laparotomy pads (4-17) were then packed within the abdomen to effect tamponade, and the abdomen was closed under tension without drains or stomata. Following correction of the coagulopathy, the abdomen was re-explored at 15 to 69 hours in the 12 survivors. Definitive surgery then was completed: bowel resection and reanastomosis; ureter reimplantation; drains for bile, pancreatic juice, and urine; and stomata for bowel or urine diversion or decompression. Eleven of 17 patients, deemed to have a lethal coagulopathy, survived. This technique of initial abortion of laparotomy, establishment of intra-abdominal pack tamponade, and then completion of the surgical procedure once coagulation has returned to an acceptable level has proven to be lifesaving in previously non-salvageable situations.
