1/74. Successful completion of endoluminal repair of an abdominal aortic aneurysm after intraoperative iatrogenic rupture of the aneurysm.PURPOSE: A method of achieving successful completion of endoluminal repair of an abdominal aortic aneurysm (AAA) in the presence of intraoperative iatrogenic rupture of the aneurysm is reported. methods: An 83-year-old woman with an AAA that was 7 cm in diameter was treated electively by means of endoluminal repair with a Vanguard bifurcated prosthesis (boston Scientific, Natick, Mass). No difficulty was experienced with the introduction of the delivery catheter, despite extreme angulation in the aneurysm. An acute episode of hypotension prompted an aortogram to be performed. Extravasation of contrast outside the aneurysm sac was demonstrated. The balloon on the delivery catheter was immediately advanced to the suprarenal aorta and inflated. hypotension was reversed, and hemodynamic stability was restored, thus enabling deployment of the prosthesis to proceed and the repair to be completed by means of the endoluminal method. RESULTS: The patient's blood pressure remained stable after deflation of the balloon, allowing a postprocedure aortogram to be performed. Exclusion of the aneurysm sac was demonstrated. Exclusion of the aneurysm sac from the circulation and a large retroperitoneal hematoma were confirmed by means of a postoperative contrast computed tomography scan. convalescence was complicated by acute renal failure, pneumonia, and prolonged ileus. The patient remained well and active at the follow-up examination 6 months after operation. CONCLUSION: Iatrogenic perforation of an AAA during endoluminal repair may be treated by endovascular means and does not necessarily require conversion to open repair, although this may be the safest option.- - - - - - - - - - ranking = 1keywords = open (Clic here for more details about this article) |
2/74. Iatrogenic spondylolysis leading to contralateral pedicular stress fracture and unstable spondylolisthesis: a case report.STUDY DESIGN: A case report of iatrogenic spondylolysis as a complication of microdiscectomy leading to contralateral pedicular stress fracture and unstable spondylolisthesis. OBJECTIVE: To improve understanding of this condition by presenting a case history and roentgenographic findings of a patient that differ from those already reported and to propose an effective method of surgical management. methods: A 67-year-old woman with no history of spondylolysis or spondylolisthesis underwent an L4-L5 microdiscectomy for a left herniated nucleus pulposus 1 year before the current consultation. For the preceding 8 months, she had been experiencing low back and bilateral leg pain. Imaging studies revealed a left L4 spondylolytic defect and a right L4 pedicular stress fracture with an unstable Grade I spondylolisthesis. RESULTS: The patient was treated with posterior spinal fusion, which resulted in complete resolution of her clinical and neurologic symptoms. CONCLUSIONS: Iatrogenic spondylolysis after microdiscectomy is an uncommon entity. However, it can lead to contralateral pedicular stress fracture and spondylolisthesis, and thus can be a source of persistent back pain after disc surgery. Surgeons caring for these patients should be aware of this potential complication.- - - - - - - - - - ranking = 581.58358297832keywords = fracture (Clic here for more details about this article) |
3/74. Iatrogenic ulnar nerve injury after percutaneous cross-pinning of supracondylar fracture in a child.Supracondylar fracture of the humerus is the most common fracture of the elbow in children and has been treated by a variety of methods. Recently, stabilization of reduced fractures with percutaneous pin fixation has become the accepted method of treatment. ulnar nerve injury is a complication of percutaneous pinning of supracondylar fractures, although many authors have reported that it resolves spontaneously after removal of the pin.- - - - - - - - - - ranking = 664.66695197522keywords = fracture (Clic here for more details about this article) |
4/74. Emergency portacaval shunt for control of hemorrhage from a parenchymal fracture after adult-to-adult living donor liver transplantation.As more adults undergo transplantation with partial liver grafts, the unique features of these segments and their clinical significance will become apparent. A patient presented with life-threatening hemorrhage from an iatrogenic laceration to a right lobe graft 11 days after transplantation. The creation of a portacaval shunt effectively controlled the bleeding, allowing more elective replacement of the organ with another right lobe graft. The regeneration process combined with increased portal blood flow and relative outflow limitation may have set the stage for this complication. Any disruption of the liver parenchyma during transplantation should be securely repaired and followed cautiously. Portacaval shunting is an option for controlling hemorrhage from the liver in transplant recipients. The timely availability of a second organ was likely the ultimate determinant of survival for this patient.- - - - - - - - - - ranking = 332.33347598761keywords = fracture (Clic here for more details about this article) |
5/74. Contribution of magnetic resonance imaging for the diagnosis of median nerve lesion after endoscopic carpal tunnel release.Deterioration of pre-existing signs or appearance of a nerve deficit raise difficult problems during the complicated course following endoscopic carpal tunnel release. One possible explanation is transient aggravation of nerve compression by passage of the endoscopy material, but these signs may also be due to incomplete section of the flexor retinaculum or an iatrogenic nerve lesion. Each case raises the problem of surgical revision. The authors report three cases of open revision in which MRI allowed a very precise preoperative diagnosis of the lesions and all of the MR findings were confirmed during surgical revision. In the first case, MRI showed section of the most radial branches of the median nerve (collateral nerves of the thumb, index finger and radial collateral nerve of the middle finger). The proximal origin of the nerve of the 3rd web space, above the retinaculum, an anatomical variant, was also identified. Section of 2/3 of the nerve of the 3rd web space, proximal to the superficial palmar arch, was observed in the second case. Simple thickening of the nerve of the 3rd web space, without disruption after opening of the perineurium, was observed in the third case. MRI therefore appears to be an examination allowing early and precise definition of indications for surgical revision in this new iatrogenic disease.- - - - - - - - - - ranking = 2keywords = open (Clic here for more details about this article) |
6/74. Iatrogenic vertebral body compression fracture in a premature infant caused by extreme flexion during positioning for a lumbar puncture.We present a case of vertebral body compression fracture that resulted from manual flexion of the spine of a premature infant in preparation for a lumbar puncture. Vertebral body fractures due to abnormal flexion in child abuse have been described. However, such fractures due to lumbar puncture-related positioning have not been reported. We present a pre-term infant who developed an L3 vertebral body compression fracture immediately after lumbar puncture.- - - - - - - - - - ranking = 664.66695197522keywords = fracture (Clic here for more details about this article) |
7/74. Laparoscopic management of colonoscopic perforations.Colonic perforation is a dangerous complication of colonoscopy, both diagnostic and therapeutic, and its management has become controversial. The question of conservative vs operative treatment is still under debate. Despite the recent expansion and wide acceptance of laparoscopy by surgeons, the feasibility of this technique as a means of treating abdominal emergencies has also been questioned. Of 575 patients admitted to our institution for abdominal emergencies between 1993 and 1998, 365 were treated via a laparoscopic approach. Two of these patients were treated for colonoscopic perforations, one after a diagnostic procedure and one after an operative procedure. Our technique employs an open umbilical approach with two other trocars introduced in the right iliac fossa and left flank. In the first case, a diverticular perforation of the subperitoneal rectum was suspected. The abdomen was copiously irrigated with saline solution and a drain was left in the pelvis. In the second patient, localized peritonitis was found in the left iliac fossa due to a microperforation of the sigmoid colon. It was repaired with a single absorbable suture. The postoperative course was unremarkable in both cases. In patients with an emergency abdomen due to a postcolonoscopy perforation, we consider the laparoscopic approach feasible and safe in experienced hands. It allowed us to avoid an unnecessary laparotomy and other time-consuming and expensive diagnostic investigations. This approach represents an excellent means of managing this type of emergency abdominal situation.- - - - - - - - - - ranking = 1keywords = open (Clic here for more details about this article) |
8/74. Endovascular repair of latrogenic subclavian artery perforations using the Hemobahn stent-graft.PURPOSE: To report the use of a new self-expanding endograft for percutaneous treatment of iatrogenic subclavian artery perforations. case reports: The subclavian artery of 2 patients was inadvertently cannulated during percutaneous attempts to implant a permanent pacemaker in one and catheterize the subclavian vein in the other. Because both patients had serious comorbidities, endovascular repair of the subclavian perforations was performed using the Hemobahn endograft, a nitinol stent covered internally with expanded polytetrafluoroethylene. The endoprostheses were successfully deployed via an ipsilateral brachial artery access. No signs of endograft occlusion, migration, deformation, or fracture have been observed during follow-up at 12 and 10 months, respectively, in these patients. CONCLUSIONS: The Hemobahn stent-graft appears well suited to repairing subclavian artery injuries. Longer follow-up will determine if the design of this endograft will resist compression in this vascular location.- - - - - - - - - - ranking = 83.083368996903keywords = fracture (Clic here for more details about this article) |
9/74. Iatrogenic injuries of renal pelvis and ureter following open surgery for urolithiasis.OBJECTIVE: To study the types of injuries of renal pelvis and ureter following open surgical procedures for urolithiasis and predisposing factors leading to such injuries and discuss various options for the management of iatrogenic injuries of the renal pelvis and ureter. patients AND METHOD: Case files and available radiographs of the patients who were managed for ureteral and renal pelvic injuries were reviewed. Initial procedure, mode of injury and clinical course were noted. RESULTS: The study consisted of 13 patients (9 males and 4 females). Age of the patients ranged from 18 to 65 years. Eight patients had injuries of renal pelvis or ureteropelvic junction and 5 patients got ureteral injuries. Primary management of ureteral and renal pelvic injuries was successful in 9 patients. Four patients required further surgery. Three out of 4 patients underwent nephrectomy and in 1 patient renal function deteriorated despite secondary pyeloplasty. Among 3 patients who had nephrectomy, one died postoperatively due to sepsis and haemorrhage. CONCLUSION: Injuries of the renal pelvis and ureter have significant morbidity and even mortality. Peroperative recognition of these injuries and appropriate management can prevent the late sequele of these injuries such as stricture formation leading to progressive renal damage.- - - - - - - - - - ranking = 5keywords = open (Clic here for more details about this article) |
10/74. Excluded-loop hepatojejunal anastomosis with use of laparoscopy in late management of iatrogenic ligature of the bile duct.Although the procedures adopted for bile duct surgery are routine, serious complications occasionally occur. This article reports the authors' experience in managing an iatrogenic ligature of the bile duct. The patient in this case had undergone open cholecystectomy and had significant jaundice in the early postoperative period. During the investigation, a complete ligature of the common hepatic duct was discovered. An anastomosis of the common hepatic duct with an excluded jejunum loop was performed with use of laparoscopy. Periodic follow-up continuing until 30 months after surgery showed the patient was asymptomatic, and ultrasonography, percutaneous transhepatic cholangiography, and cholangioresonance findings were normal. We consider the procedure feasible and technically advantageous when done with the assistance of laparoscopy.- - - - - - - - - - ranking = 1keywords = open (Clic here for more details about this article) |
