Left gastric artery pseudoaneurysm following traumatic pancreatic transection.

A 24-year-old man presented to us 10 days after suffering blunt trauma to the abdomen. He was diagnosed with pancreatic transection and underwent distal pancreatectomy and splenectomy. Two weeks after the operation, he developed intra-abdominal haemorrhage. Selective visceral angiogram revealed left gastric artery pseudoaneurysm, which had embolised. His recovery was uneventful. To our knowledge, ruptured left gastric artery pseudoaneurysm following pancreatic trauma, has not been reported before. In this article, we discuss some vascular complications of pancreatic trauma.

Changing profile of Budd Chiari syndrome in India.

There is increasing evidence that Budd Chiari syndrome occurs when acquired predisposing factor(s) affect a susceptible individual with one or more underlying thrombophilic conditions. Geographical variations in disease pattern of Budd Chiari syndrome exist, which may reflect differing predisposing factors. We review a change in disease profile of Budd Chiari syndrome in India over the past three decades. While earlier studies from India reported isolated inferior vena cava (IVC) obstruction as the commonest disease type, this is a minority in more recent reports where a combination of IVC and hepatic vein obstruction is the commonest type. Longer duration of illness has been shown to be associated with IVC obstruction and the recent change in disease profile in India may reflect earlier diagnosis of Budd Chiari syndrome. Poverty, malnutrition, recurrent bacterial infections and filariasis have been previously suggested as predisposing factors for IVC obstruction. Improvement in hygiene and sanitation may partly explain the recent change in disease profile of Budd Chiari syndrome in India.

Direct intrahepatic cavo-portal shunts in Budd-Chiari syndrome: Role of simultaneous fluoroscopy and trans-abdominal ultrasonography.

BACKGROUND: Transjugular intrahepatic porto-systemic shunt (TIPS) for Budd-Chiari syndrome (BCS) can be inserted from inferior vena cava or hepatic vein to portal vein. The former is performed when hepatic veins are not suitable and is technically more challenging. METHODS: In this retrospective study, 7 patients with chronic BCS needed cavo-portal shunt as hepatic veins were neither amenable to plasty nor provided access for TIPS placement. Simultaneous fluoroscopic and trans-abdominal ultrasound guidance was used at the time of portal vein puncture. RESULTS: Technical success and clinical improvement were obtained in all patients. Median 3 (range 1-4) attempts were needed to puncture the portal vein. There were no significant complications. Uncovered stents were used in six patients and stent occlusion was common, but could be managed by re-intervention. CONCLUSION: Cavo-portal shunt is an effective technique for patients with BCS uncontrolled by medical therapy. Additional trans-abdominal ultrasound in oblique parasagittal plane keeps the procedure safe.

Kenny-Caffey syndrome.

Kenny-Caffey syndrome is a rare hereditary skeletal syndrome characterized by dysmorphic features, severe growth retardation, classical radiological changes and hypocalcemia with hypoparathyroidism at an early age. We report an 8-month-old girl child with Kenny-Caffey syndrome who had most of the features of the syndrome. Any child with hypocalcemia who has typical facial features should raise a suspicion of this syndrome.

Evaluation of radiation dose to patients during abdominal embolizations.

BACKGROUND: Abdominal embolization procedures performed using digital subtraction angiography (DSA) is on the increase in the present-day scenario owing to their diagnostic and therapeutic values. These procedures involve prolonged fluoroscopy times and may tend to impart high radiation dose to patients if adequate radiation safety measures are not taken. AIM: To evaluate radiation dose imparted to patients and the work practices involved therein during abdominal embolization procedures. MATERIALS AND METHODS: Forty-two patients who underwent abdominal embolizations performed using DSA equipment were included in the study. Dose area product (DAP) was measured using DAP meter and values obtained were used for calculating entrance surface dose (ESD). Work practices of personnel involved in conducting the procedure were evaluated based on the choice of field sizes, selection of appropriate fluoro-modes, and optimization techniques. RESULTS AND CONCLUSIONS: The mean ESD values during hepatic embolization, renal embolization, splenic artery embolization and transarterial chemoembolization (TACE) were 1.2, 1.01, 1.19, and 1.03, respectively. No deterministic effects of radiation, such as transient or main erythema, were noticed for a few patients whose doses exceeded the threshold doses.
