Efficacy of embolization in traumatic uterine vascular malformations

PURPOSE: To evaluate the efficacy of embolotherapy in patients with bleeding traumatic uterine arteriovenous malformations (AVMs). MATERIALS AND METHODS: A retrospective review of all patients who underwent pelvic arterial embolization at our institution between July 1992 and September 2002 was performed. Fifteen patients were diagnosed with a uterine vascular malformation on duplex ultrasonography and correlative MR imaging. Serial beta-human chorionic gonadotropin levels were measured to exclude gestational trophoblastic neoplasia. All patients underwent transcatheter embolization of the uterine arteries. Embolizations were performed with use of standard 4-5-F catheters and microcatheters when necessary. Embolic agents in the 25 procedures included glue only (n = 13), polyvinyl alcohol (PVA) particles and glue (n = 4), PVA particles (n = 2), Gelfoam (n = 2), coils (n = 1), PVA particles and coils (n = 1), glue and Gelfoam (n = 1), and glue and coils (n = 1). PVA particle size ranged from 350 to 1,000 micro m. Outcomes assessed were cessation of bleeding, persistence or resolution of the AVM, complications, and pregnancy after embolization. These were assessed by chart, laboratory, and imaging reviews. RESULTS: A total of 25 embolization procedures were performed in 15 patients. Six patients required repeat embolization (one patient underwent embolization on six occasions; five patients had two embolization procedures each) for recurrence of bleeding. Sixteen procedures were performed on an elective basis and nine were performed on an emergent basis. The technical success rate of embolization was 100%. The clinical success rate was 93%: bleeding was controlled in 14 of 15 patients and one patient underwent a hysterectomy. Four of the 15 patients subsequently had a total of five uneventful intrauterine pregnancies carried to term. The 14 patients who underwent successful embolization had no recurrence of bleeding at a median follow-up of 53 months (range, 3-124 months) after treatment. Three patients were eventually lost to follow-up. One minor complication (0.4%) of non-flow-limiting dissection of the internal iliac artery occurred. CONCLUSION: Percutaneous embolotherapy is a safe and effective treatment for traumatic AVMs. This procedure allows for preservation of uterine function with the possibility of future pregnancy and should be considered as a primary treatment option.     

Percutaneous transhepatic cholangiography and biliary drainage after liver transplantation: A five-year experience

Evaluation of the biliary tract by percutaneous transhepatic cholangiography (PTC) is often required in liver transplant patients with an abnormal postoperative course. Indications for PTC include failure of liver enzyme levels to return to normal postoperatively, an elevation of serum bilirubin or liver enzyme levels, suspected bile leak, biliary obstructive symptoms, cholangitis, and sepsis.Over a 5-year period 625 liver transplants in 477 patients were performed at the University Health Center of Pittsburgh. Fifty-three patients (56 transplants) underwent 70 PTCs. Complications diagnosed by PTC included biliary strictures, bile leaks, bilomas, liver abscesses, stones, and problems associated with internal biliary stents.Thirty-two percutaneous transhepatic biliary drainage procedures were performed. Ten transplantation patients underwent balloon dilatation of postoperative biliary strictures. Interventional radiologic techniques were important in treating other complications and avoiding additional surgery in many of these patients.     

Functional outcome of an early anterior cruciate ligament reconstruction in comparison to delayed: Are we waiting in vain?

Background

Surgical techniques of ACL reconstruction (ACLR) have evolved over the past three decades along with debate regarding timing of reconstruction. It was a widespread belief that the timing of surgery was an important factor in determining the resulting stiffness after ACLR. Delayed rather than early reconstruction of the ACL is the current recommended treatment since it is thought to give a better functional outcome. However, there is no consensus in the literature regarding the optimal time of surgical intervention. The purpose of this study was to compare the range of motion and functional outcome in patients who underwent ACLR early with those that were delayed.

Analysis of Patterns and Treatment Strategies for Mandibular Condyle Fractures: Review of 175 Condyle Fractures with Review of Literature

This study aims to evaluate incidence, patterns and epidemiology of mandibular condylar fractures (MCF) to propose a treatment strategy for managing MCF and analyze the factors which influence the outcome. One hundred and seventy-five MCF’s were evaluated over a four year period and their pattern was recorded in terms of displacement, level of fracture, age of incidence and dental occlusion. Of the 2,718 facial bone fractures, MCF incidence was the third most common at 18.39 %. Of 175 MCF 58.8 % were unilateral and 41.12 % were bilateral. 67 % of bilateral fractures and 43.8 % of unilateral fractures were associated with midline symphysis and contralateral parasymphysis fractures respectively. Most of the MCF was seen in the age group of above 16 years and 50 % of them were at subcondylar level (below the neck of the condyle). Majority of MCF sustained due to inter personal violence were undisplaced (72.7 %) and contrary to this majority of MCF sustained during road traffic accident were displaced. 62.9 % of total fractures required open reduction and rigid fixation and 37.1 % were managed with closed reduction. 80 % of MCF managed with closed reduction were in the age group of below 16 years. From this study it can be concluded that the treatment algorithm proposed for managing MCF is reliable and easy to adopt. We observed that absolute indication for open reduction of MCF is inability to achieve satisfactory occlusion by closed method and absolute contraindication for open reduction is condylar head fracture irrespective of the age of the patient.     

Limberg Flap for Sacrococcygeal Pilonidal Sinus a Safe and Sound Procedure

Sacrococcygeal pilonidal sinus (SC-PSD) is an acquired condition usually seen in young adults especially males. This prospective study has been performed to determine effects of the Limberg flap rotation surgery for sacrococcygeal pilonidal sinus, its feasibility to the patients, their compliance, and outcomes such as wound infection, postoperative pain relief, recurrence rates, and return to work. A total of 30 patients were operated by the same two surgeons from January 2009 to June 2011, including both primary and recurrent diseases, and patients with previous incision and drainage done for the pilonidal abscess. All patients successfully underwent surgery, with very minimal postoperative pain, stayed in hospital for average 5 days, returned to work after 3 weeks, with 3 patients having flap edema, 2 having flap necrosis, and no recurrences so far. Patients with flap edema and flap necrosis took 2–3 weeks to heal with regular dressing and antibiotic usage. Limberg flap for sacrococcygeal pilonidal sinus was found very useful and sound in terms of postoperative pain, infection rates, and early return to work with almost nil recurrences.     

Predictors of long-term survival in patients with gallbladder cancer

The aim of this study was to examine the predictors of long-term survival (>24 months) in patients with gall bladder cancer. A retrospective review of 117 cases of gall bladder cancer resected between 1989 and 2000. The resections included 80 simple cholecystectomies and 37 extended procedures. Patients with survival >24 months (n=44) were compared with those having survival <24 months (n=73) for 17 prognostic factors. Overall median survival was 16 months with a 5-year survival of 27%. T status (P=.000) and adjuvant chemoradiotherapy (P=.001) were independent predictors of long-term survival. Survival advantage was seen in T3N+ve disease (P=.007) with extended procedures. Complete (R0) resection was attained in 30 patients with a 5-year survival advantage of 30% as compared with incomplete (R1) resection (P=.0002). Adjuvant chemoradiotherapy improved survival in simple cholecystectomy group (P=.0008) but no advantage was seen after extended procedures. Stage III (P=.001) and node-positive disease (P=.0005) had significant benefit with adjuvant therapy. Poor differentiation and vascular invasion were associated with poor long-term survival. R0 resection was associated with prolonged survival. Extended procedures improved survival in patients with T3N+ve disease. Addition of chemoradiotherapy made significant improvement in long-term survival in stage III and node-positive lesions and in patients undergoing simple cholecystectomy. R0 resection predicted long-term survival in gall bladder cancer. T3 N+ve disease had better survival after extended procedures. Adjuvant chemoradiotherapy improved survival in stage III and node-positive disease. Poor differentiation and vascular invasion were adverse predictors of survival.     

Comparative study of ankle arthrodesis using cross screw fixation versus anterior contoured plate plus cross screw fixation

Arthrodesis of the ankle joint is still the traditional treatment for symptomatic osteoarthritis. This comparative study was done to assess the functional outcome of open ankle fusion using either cross screw fixation (group A) or anterior contoured plate and cross screw fixation (group B) in a consecutive series of 22 patients. All the patients had the same inclusion criteria. All the patients in both groups underwent the same operative technique and were operated by the same surgeon. Mean follow-up was 26.8 months. The mean time to fusion was 18.8 weeks in group A and 16.8 weeks in group B (p = 0.046). The mean American Orthopaedic Foot and Ankle Society (AOFAS) Ankle and Hind foot score at the final follow-up was 79 in group A and 86 in group B (p = 0.23). Two patients in group A that went to non-union required re-arthrodesis using contoured plate and cross screw fixation; both attained eventual union. We conclude that anterior contoured plate plus cross screw fixation is a simple and reproducible technique for ankle arthrodesis that gives stable internal fixation and excellent clinical results.
